Mike's dad invested $1,000 into Apple Stock the day he was born. If Mike keeps that money invested until the age of 30, how much will the investment be worth if the average rate is 6.5%, compounded weekly?

Answers

Answer 1

The investment will be worth approximately $4,667.27 after 30 years of compounding at a rate of 6.5% per annum, compounded weekly.

Assuming that the investment compounds weekly for 30 years, the formula to calculate the future value of the investment would be:

FV = [tex]PV * (1 + r/n)^{(n*t)}[/tex]

where:

PV = present value (initial investment) = $1,000

r = annual interest rate = 6.5%

n = number of times the interest is compounded per year = 52 (weekly)

t = number of years the money is invested = 30

Plugging in these values, we get:

FV = [tex]\$1,000 * (1 + 0.065/52)^{(52*30)}[/tex]

FV = [tex]\$1,000 * (1 + 0.00125)^{1560}[/tex]

FV = [tex]\$1,000 * 2.693[/tex]

FV = $2,693.29

Therefore, the investment will be worth $2,693.29 when Mike turns 30.

The formula for compound interest is a mathematical formula that calculates the final value of an investment based on the initial investment amount, the interest rate, and the number of compounding periods per year. It takes into account the effect of compounding on the investment, which means that the interest earned is added back to the principal amount, so that the investment grows at an accelerating rate over time.

A trucks has a maximum load limit of 5000 kg. Can it safely cary 230 bushels of canola, if the conversion factor is 44.092 bushels/tonne?

Answers

After answering the provided question, we can conclude that As a result, equation 230 bushels = (230/44.092) tonnes = 5.22 tonnes.

What is equation?

In mathematics, an equation is a statement that states the equivalence of two expressions. An equation consists of two sides separated by an algebraic equation (=). For instance, the argument "2x + 3 = 9" states that the sentence "2x + 3" equals the number "9". The purpose of solving equations is to find the value or amounts of the variable(s) that always allow the equation to be true. Equations can just be simple or complicated, regular or nonlinear, and contain one or more variables. For example, in the equation "x2 + 2x - 3 = 0," the variable x is raised to the second power. Lines are used extensively in mathematics, including algebra, calculus, and geometry.

To find out if the truck can safely transport 230 bushels of canola, we must first convert the bushels to kilos. Using the conversion factor, we can convert bushels to tonnes and finally tonnes to kilos.

1000 kg Equals 1 tonne

1 tonne is 44.092 bushels

As a result, 230 bushels = (230/44.092) tonnes = 5.22 tonnes.

We multiply by 1000 to convert tonnes to kilogrammes:

5.22 tonnes = 5220 kg

Because 5220 kg is less than the truck's maximum weight restriction of 5000 kg, it may safely transport 230 bushels of canola.

Determine the lateral and total surface area of the pyramid.

Answers

The lateral and total surface area of the square pyramid is 196.22 cm² and 232.22 cm².

what exactly is a square pyramid?

A square pyramid is a three-dimensional geometric shape that consists of a square base and four triangular faces that meet at a common vertex, called the apex. All the triangular faces are congruent, and the base and apex are aligned along the same vertical axis. A square pyramid is a type of pyramid because it has a polygonal base, which is a square in this case.

Now,

The lateral surface area of a square pyramid is given by the formula:

L = (1/2)Pl

where P= perimeter of the base and l = slant height .

To find the perimeter of the base, we can use the formula for the perimeter of a square:

P = 4s

where s= length of a side of the square. Substituting s = 6 cm, we get:

P = 4(6) = 24 cm

To find the slant height , we can use the Pythagorean theorem:

l² = h²+ (s/2)²

where h is the height of the pyramid and s is the length of a side of the square base. Substituting h = 16 cm and s = 6 cm, we get:

l² = 16² + (6/2)² = 256 + 9 = 265

l = √265 ≈ 16.28 cm

Therefore, the lateral surface area is

L = (1/2)Pl = (1/2)(24)(16.28) ≈ 196.22 cm²

The total surface area of a square pyramid is given by the formula:

T = B + L

where B is the area of the base. Since the base is a square with side length 6 cm, the area of the base is:

B = s² = 6² = 36 cm²

Therefore, the total surface area of the pyramid is:

T = B + L = 36 + 196.22 ≈ 232.22 cm²

Answers

Option B. 2 3. Sarah spends 2/3 hour vacuuming her mom's car. 2 3 hour, which means 2 hours and 20 minutes.

The problem is asking us to find the total amount of time Sarah spends washing her mom's car. We know that Sarah spends 4 times as long washing the car as she does vacuuming the car, and she spends 1/6 hour vacuuming. To find the amount of time Sarah spends washing, we need to multiply the time she spends vacuuming by 4:

1/6 hour x 4 = 4/6 hour = 2/3 hour

Sarah spends 4 times as long washing the car as she spends vacuuming, which is:

4 * 1/6 = 4/6 = 2/3 hour

Therefore, the total amount of time Sarah spends washing her mom's car is:

1/6 + 2/3 = 1/6 + 4/6 = 5/6 hour

Therefore, Sarah spends 2/3 hour washing her mom's car. The answer is (b) 2 3 hour, which means 2 hours and 20 minutes.

assume that male and female births are equally likely and that the birth of any child does not affect the probability of the gender of any other children. find the probability of exactly nine boys in ten births. round the answer to the nearest thousandth.

Answers

The probability of exactly nine boys in ten births is 0.010 (rounded to the nearest thousandth).

In a situation where male and female births are equally likely and the birth of any child does not affect the probability of the gender of any other children, finding the probability of exactly nine boys in ten births is quite easy.

We can approach this using the binomial probability distribution, which provides the probability of x successes in n independent Bernoulli trials.

[tex]P(x) = (nCx) * p^x * q^(n-x)[/tex]

Where P(x) is the probability of x successes, n is the total number of trials,

p is the probability of success,

q is the probability of failure, and nCx is the binomial coefficient.

Assuming that the probability of a male or female birth is 1/2 or 0.5 and using the above formula, we can find the probability of exactly nine boys in ten births as follows:

P(9) = (10C9) * (0.5)^9 * (0.5)^(10-9)P(9)

       = 10 * 0.001953125 * 0.5P(9)

Answers

By solving the generated equation, Calvin caught 16 smallmouth bass and 9 largemouth bass.

What is meant by equation?

An equation states that the two expressions have the same value or are equivalent to each other. Equations are used in various areas of mathematics, science, engineering, and everyday life to describe relationships and solve problems.

Let x represent the number of smallmouth bass that Calvin caught, and y represent the number of largemouth bass that he caught.

From the problem, we know that the total number of fish that Calvin caught is 25:

x + y = 25

We also know that the number of smallmouth bass that Calvin caught is 2 less than double the number of largemouth bass that he caught:

x = 2y - 2

We can use the first equation to solve for one of the variables in terms of the other. For example, we can solve for y:

y = 25 - x

Substituting this into the second equation, we get:

x = 2(25 - x) - 2

Simplifying this equation, we get:

x = 48 - 2x

Solving for x, we get:

3x = 48

x = 16

Substituting this value of x back into either of the original equations, we can solve for y:

y = 25 - x = 25 - 16 = 9

Therefore, Calvin caught 16 smallmouth bass and 9 largemouth bass.

Answers

Cross product of two vectors, a and b, is (3, 5, -15) and cross product a x b is orthogonal to both vectors.

The cross product of two vectors, a and b, is calculated by taking the determinant of the matrix formed by their components:


a x b =
   |i  3  -3|

   |-1 0   5|

   | 0 0   0|


This can also be written as:

   (i, 3, -3) x (-1, 0, 5) = (3, 5, -15)


Therefore, a x b = (3, 5, -15).

To verify that it is orthogonal to both a and b, we must check if their dot product is zero:

   (
a, b) = (i + 3j - 3k, -i + 5k) = (i - i + 3j - 3k + 5k) = 3j + 2k = 0


Since the dot product of a and b is zero, we can conclude that the cross product a x b is orthogonal to both vectors.

Hence, Cross product of two vectors, a and b, is (3, 5, -15) and cross product a x b is orthogonal to both vectors.

Using  Gauss-Jordan elimination method (RREF), the solution for the given system of equations is X1 = -t, X2 = t-3, and X3 = t.

The Gauss-Jordan elimination method is used to solve a system of equations. To solve a system of equations using the Gauss-Jordan elimination method, we must first construct the augmented matrix of the system.

The augmented matrix for the system of equations b) a) 2x1 + 4x2 - X3 = 2 X1 + x2 + 3x3 = -13 2x1 X2 = -2 3x1 - x2 - X3 = -7 X1 + 4x2 - 9x3 = 2 4x1 - 3x2 + 2x3 = -11 is:

Answers

The time for 630 kilometres would need to be covered in 5 hours if you were doing 126 kilometres per hour.

To find the time when distance and speed are known, we can use the formula: time = distance ÷ speed, where time is measured in hours, distance is measured in kilometers, and speed is measured in kilometers per hour. By plugging in the values, we can calculate the time it takes to travel a distance at a given speed.

time = distance ÷ speed

where time is measured in hours, distance is measured in kilometers, and speed is measured in kilometers per hour.

In this case, we are given the distance as 630 km and the speed as 126 km/h. Plugging these values into the formula, we get:

time = 630 km ÷ 126 km/h

We can simplify this expression by dividing 630 by 126:

time = 5 hours

Area = length x width = l x w

Tο find οut hοw many tiles Mοira needs, we first need tο find the tοtal area οf her kitchen flοοr. We can dο this by multiplying the length and width οf the kitchen:

Area οf kitchen flοοr = length x width = 12' x 18' = 216 square feet.

 The bus fare in a city is two dollars people who use the bus have the option of purchasing a monthly coupon book for $29 with a coupon book the fair is reduced to one dollar determine the number of times in a month the bus most be used so that the total monthly cost without the coupon book is the same as the monthly cost with a coupon book 

Answers

Answer:

Total Cost = 2(29) = $58 (without coupon book)

Total Cost = $29 + $1(29) = $58 (with coupon book)

Step-by-step explanation:

Let's assume that x is the number of times the bus is used in a month.

Without the coupon book, the total monthly cost would be:

Total Cost = 2x

With the coupon book, the total monthly cost would be:

Total Cost = $29 + $1x

We want to find the value of x that makes these two total costs equal. So we set them equal to each other and solve for x:

2x = 29 + 1x

2x - 1x = 29

x = 29

So if the bus is used 29 times in a month, the total monthly cost without the coupon book will be the same as the monthly cost with the coupon book. In this case, the total monthly cost would be:

Total Cost = 2(29) = $58 (without coupon book)

Total Cost = $29 + $1(29) = $58 (with coupon book)

Therefore, if a person uses the bus more than 29 times in a month, it would be more cost-effective for them to purchase the coupon book. If they use the bus less than 29 times, it would be more cost-effective for them to pay the regular fare of $2 per ride.

The EPA wants to conduct a survey to determine the current approval rating on the government's handling of environmental action. From previous studies, they know that they need to poll 275 people to achieve their desired level of confidence. If they want to keep the same level of confidence but divide the margin of error in third, how many people will they have to poll?

Answers

Answer: Assuming that the desired level of confidence and the population size remain constant, the sample size required for a given margin of error is proportional to the square of the standard normal deviate corresponding to the desired level of confidence.

That is, if n is the current sample size and m is the current margin of error, and we want to divide the margin of error by 3 while keeping the same level of confidence, then we need to find the new sample size, n', that satisfies the equation:

n'/n = (zα/2 / z'α/2)²

where zα/2 is the standard normal deviate corresponding to half the desired level of confidence, and z'α/2 is the standard normal deviate corresponding to half the desired level of confidence and one-third the margin of error.

Assuming a desired level of confidence of 95%, we have:

zα/2 = 1.96

z'α/2 = 1.96 / 3 = 0.6533 (rounded to four decimal places)

Substituting these values and the given values of n and m, we get:

n'/275 = (1.96 / 0.6533)²

Solving for n', we get:

n' = 275 * (1.96 / 0.6533)²

Using a calculator, we get:

n' ≈ 887

Therefore, the EPA would need to poll approximately 887 people to achieve the same level of confidence with a margin of error divided by three.

Step-by-step explanation:

Specifically, generate a reference sample of the same size of the training set. This can be done in a couple of ways, e.g., (i) sample uniformly for each variable, or (ii) by randomly permuting the values within each variable independently.
Build a classification tree to the training sample (class 1) and the reference sample (class 0) and describe the terminal nodes having highest estimated class 1 probability. Compare the results to the results near Table 14.1 (ESL), which were derived using PRIM.

Answers

The estimated probabilities of belonging to a particular class in each terminal node can also be used to predict the class of new observations.

To build a classification tree, we need a training set and a reference sample of the same size. The reference sample is a set of data that we use to compare our model's performance against random guessing. We can generate a reference sample in a couple of ways.

To estimate the probability of a new observation belonging to a particular class, we calculate the proportion of training samples or reference samples in that terminal node that belong to that class.

The terminal nodes with the highest estimated class 1 probability are the ones where most of the training samples belong to class 1. These nodes will be useful in predicting the class of new observations.

However, PRIM provides a more detailed summary of the important regions, whereas classification trees provide a more visual representation of the decision boundaries.

This circle graph shows how the students in two sixth-grade classes get to school. Fifty students were surveyed. What percent takes the bus?

Answers

Forty percent of the students surveyed take the bus to school, as indicated by the circle graph.

To calculate the percent of students who take the bus to school, we can use the information provided in the circle graph. There are a total of 50 students surveyed, and the graph indicates that 20 of them take the bus. To find the percent, we can first divide the number who take the bus (20) by the total number surveyed (50). This gives us 0.4, which, when multiplied by 100, is 40%. Therefore, 40% of the students surveyed take the bus to school. Hence, Forty percent of the students surveyed take the bus to school, as indicated by the circle graph.

What is quadratic equatiοn?

A quadratic equatiοn is a type οf pοlynοmial equatiοn οf the secοnd degree, which can be written in the fοrm:

[tex]ax^2 + bx + c = 0[/tex]

Where "a", "b", and "c" are cοnstants, and "x" is the variable. The cοefficient "a" must nοt be equal tο zerο, as this wοuld result in a linear equatiοn.

The quadratic equatiοn can be sοlved using the quadratic fοrmula, which is:

x = (-b ± sqrt(b² - 4ac)) / 2a

Tο find the rοοts οf the functiοn, we need tο find the values οf x that make y equal tο zerο since the rοοts οf a functiοn are the values οf x that make the functiοn equal tο zerο.

Sο we set y tο zerο and sοlve fοr x:

0 = (x+6)(x+1)

Using the zerο prοduct prοperty, we knοw that if the prοduct οf twο factοrs is equal tο zerο, then at least οne οf the factοrs must be equal tο zerο.

Sο we set each factοr equal tο zerο and sοlve fοr x:

x + 6 = 0 οr x + 1 = 0

x = -6 οr x = -1

Therefοre, the rοοts οf the functiοn are x = -6 and x = -1.

The center of dilation is (-3, 15). The scale factor is not the same for all sides of the triangles, which means that the dilation is not a similarity transformation.

Describe Transformation?

In mathematics, a transformation is a function that maps one set of values, called the domain, to another set of values, called the range. The term is commonly used in geometry and algebra to describe a change in the position, size, or shape of a geometric object or algebraic equation.

Transformations can be classified into several types, including translation, rotation, reflection, scaling, and shearing. Each type of transformation changes the appearance of the object in a specific way.

To identify the center of dilation and scale factor, we can compare the coordinates of corresponding points in the two triangles.

The center of dilation is the point about which the dilation occurs. It can be found by calculating the intersection of the lines joining corresponding points in the two triangles.

Scale factor is the ratio of the lengths of corresponding sides in the two triangles. It can be found by dividing the length of any side in the image triangle by the length of the corresponding side in the pre-image triangle.

Let's calculate the center of dilation first:

Line joining L and L': (y - 11)/(x - 5) = (8 - 11)/(3 - 5) = -3/2

Line joining M and M': (y - 9)/(x - 13) = (7.7 - 9)/(7 - 13) = -0.7/-6 = 0.1167

Line joining N and N': (y - 3)/(x - 11) = (4 - 3)/(6 - 11) = 1/-5 = -0.2

Solving any two equations simultaneously will give us the center of dilation:

(y - 11)/(x - 5) = -3/2

(y - 9)/(x - 13) = 0.1167

Solving the above two equations gives the point of intersection as (-3, 15). Therefore, the center of dilation is (-3, 15).

Now, let's calculate the scale factor:

Length of side LM = √((13-5)² + (9-11)²) = √(80)

Length of side L'M' = √((7-3)² + (7-8)²) = √(26)

Scale factor for side LM to L'M' = √(26)/√(80) = 0.470

Length of side MN = √((11-13)² + (3-9)²) = √(40)

Length of side M'N' = √((6-7)² + (4-7)²) = √(10)

Scale factor for side MN to M'N' = √(10)/√(40) = 0.5

Length of side NL = √((5-11)² + (11-3)²) = √(80)

Length of side N'L' = √((3-6)² + (8-4)²) = √(29)

Scale factor for side NL to N'L' = √(29)/√(80) = 0.544

Therefore, the scale factor is not the same for all sides of the triangles, which means that the dilation is not a similarity transformation.
