it is assumed that approximately 15% of adults in the u.s. are left-handed. consider the probability that among 100 adults selected in the u.s., there are at least 30 who are left-handed. given that the adults surveyed were selected without replacement, can the probability be found by using the binomial probability formula with x counting the number who are left-handed? why or why not?
Option C. No, because the 100 adults were selected without replacement, the selections are dependent.
The binomial probability formula assumes that the trials are independent, meaning that the probability of success or failure for each trial remains the same regardless of the outcomes of previous trials. However, in this case, the 100 adults were selected without replacement, so the probability of being left-handed for each selection depends on the outcomes of previous selections. Therefore, the binomial probability formula cannot be used to find the probability in this situation. Instead, the hypergeometric distribution can be used to account for the dependence between selections.

if £1=1. 62USD then, £650 is equivalent to $1053 in US dollars and £450 is equivalent to $729 in US dollars.
To convert British pounds to US dollars, we can multiply the pound amount by the exchange rate of pounds to dollars.
£650 in USD:
£1 = $1.62, so we can write:
650 x 1.62/1 = 1053
Therefore, £650 is equivalent to $1053 in US dollars.
£450 in USD:
Using the same method, we can calculate the value of £450 in US dollars as follows:
450 x 1.62/1 = $729
Therefore, £450 is equivalent to $729 in US dollars.
The conversion of British pounds to US dollars is a common currency exchange process, as both currencies are widely used in international trade and finance. The exchange rate between the two currencies represents the value of one currency in terms of the other. In this case, the exchange rate of £1 to $1.62 means that one British pound is worth 1.62 US dollars. To convert a certain amount of British pounds to US dollars, we simply multiply the pound amount by the exchange rate. The resulting dollar amount reflects the value of the pounds in the equivalent US dollars. Exchange rates can fluctuate frequently due to various economic and political factors, affecting the value of currencies and international transactions.

Answer:
This pair of equations is solvable by substitution, as I can easily substitute for y because it is already isolated in both equations. After substituting for y, I will solve the equations to get the value of x and then substitute that x-value into the simpler of the two equations, y = x - 1. Once I have both the x-value and y-value, they will be put into a point (x,y).
y = 3x + 3
y = x - 1
x - 1 = 3x + 3
x = 3x + 4
-2x = 4
x = -2
y = x - 1
y = ( -2 ) - 1
y = -3
The final answer to the pair of inequalities is ( -2,-3 )
Step-by-step explanation:
y = 3x + 3
y = x - 1
"substitution" means we are defining one variable by an expression of the other variable and use this identity in one of the original equations.
in our case here the main work was already done (even twice) : y is defined as expressions in x.
we even have the luxury to pick which one and then to use it in the other.
it does not matter which one you pick, it will lead to the same result.
so, let's use the identity of equation 1 in equation 2 : we replace every occurrence of y by the defined identity
y = x - 1
turns into
3x + 3 = x - 1
now we subtract x from both sides
3x + 3 - x = x - 1 - x
2x + 3 = -1
now we subtract 3 from both sides
2x + 3 - 3 = -1 - 3
2x = -4
and finally we divide both sides by 2
2x/2 = -4/2
x = -2
this result we use now in one of the original equations to get y :
e.g.
y = x - 1
y = -2 - 1 = -3
so, the solution is (-2, -3)
what is the solution for the following system of equations? -y + 3x = 6 and y = -6x + 12
The answers to the equations y = -6x + 12 and y = -y + 3x = 6 are x = 2 and y = 0, respectively.
What does "system solution" mean?A location that satisfies every equation in a system of linear equations is the system's solution. You can graph a set of linear equations and find their points of intersection, or you can use algebra to figure out the variables.
Using substitution, we may solve by replacing y in the first equation with the second equation:
-(-6x + 12) + 3x = 6
Share the ominous symbol
6x - 12 + 3x = 6
combining similar terms
9x - 12 = 6
Separate the variable and add 12 to both sides to find the value of x:
9x = 18
x = 2
Substitute 2 with x in any equation to find the value of y:
-y + 3(2) = 6.

A = 3x + 65
B = 2x + 100
The number of miles driven that would make the cost of each company the same is $35.
How to write a system of equation to model this situation?Based on the information provided above, Company A charges an initial fee of $65 for the rental plus $3 per mile driven. Therefore, the total cost, A, can be represented by this equation:
A = 3x + 65
Since Company B charges an initial fee of $100 for the rental plus $2 per mile driven. Therefore, the total cost, A, can be represented by this equation:
B = 2x + 100
For the cost of each company to be the same, we have the following:

Your parents opened a college investment account for you when you were in the first grade. They made an initial deposit of $5000 with an annual interest rate of 5% compounded quarterly.
a. Write a function A, that represent the balance (in dollars) of the investment after t years.
b. What is the current balance of the account (presuming they only made the one deposit)?
c. Will this cover your first year of school? If it does do you have any money left over? If not, how much more money do you need?
Answer:
La fórmula para calcular el balance (en dólares) de una inversión con una
A = P(1 + r/n)^(nt)
Donde:
A es el balance total después de t años
P es el depósito inicial
r es la tasa de interés anual expresada como decimal (5% = 0.05)
n es la frecuencia de capitalización por año (en este caso, 4 para compuestos trimestrales)
t es el tiempo en años
Sustituyendo los valores dados, la función que representa el balance después de t años es:
A(t) = 5000(1 + 0,05/4
b. Para encontrar el balance actual, podemos simplemente evaluar la función A en t = 0, lo que nos da:
A(0) = 5000(1 + 0,05/4
Por lo tanto, el balance actual de la cuenta es de $5000.
c. Supongamos que el costo de la matrícula y los gastos de su primer año en la universidad suman $20,000. Para determinar si la inversión cubrirá el costo, podemos evaluar la función A en t = 12 (es decir, después de 12 años desde el depósito inicial) y compararla con el costo de la matrícula y los gastos.
A(12) = 5000(1 + 0.05/4)^(4(12)) = $10,768.49
Como el balance de la cuenta después de 12 años es menor que el costo de la matrícula y los gastos, se necesitará más dinero para cubrir el costo del primer año de universidad. La cantidad adicional requerida será:
$20,000 - $10,768.49 = $9,231.51
Por lo tanto, se necesitarán $9,231.51 adicionales para cubrir el costo del primer año de universidad.

find three real-life examples of a continuous variable. which do you think may be normally distributed? why?
Of these three examples, height and weight are more likely to be normally distributed.
What is continuous variable ?
A continuous variable is a type of quantitative variable that can take on any value within a certain range. Continuous variables can be measured to any degree of precision, meaning they can be broken down into smaller and smaller increments.
Three real-life examples of a continuous variable are:
Height: Height is a continuous variable that can take any value within a certain range. It can be measured to any degree of precision, making it a continuous variable.
Time: Time is another continuous variable that can be measured to any degree of precision, from milliseconds to years.
Weight: Weight is also a continuous variable that can take any value within a certain range. It can be measured to any degree of precision, making it a continuous variable.
This is because these variables tend to follow a bell-shaped curve when plotted, with most values clustering around the mean and fewer values appearing further away from the mean. Time, on the other hand, may not be normally distributed because it can have different distributions depending on the situation, such as a bimodal distribution for the time of day people go to sleep or wake up. However, it's important to note that the normal distribution is just one of many possible distributions for continuous variables and may not always be the most appropriate or accurate for real-life situations.
Therefore, Of these three examples, height and weight are more likely to be normally distributed.

Therefore, the lateral surface area of the cube is 35/2 square inches.
What is area?In mathematics, area is the measure of the size of a two-dimensional region or surface. It is usually measured in square units, such as square meters, square feet, or square centimeters. The area of a shape or surface is determined by the amount of space it covers in a plane or on a flat surface. Areas are commonly used to describe the size of objects or spaces in a variety of contexts, including geometry, architecture, engineering, and physics. They are also used in everyday life, such as calculating the amount of carpet needed to cover a floor or the amount of paint needed to cover a wall.
Here,
Since the package is a cube, all of its faces are identical squares. Therefore, the area of one face is equal to the length of one side squared.
Let x be the length of one side of the cube. Then we have:
x² = 7(5)/8
Solving for x, we get:
x = √(7(5)/8) = sqrt(35/8)
The lateral surface area of the cube is the sum of the areas of the four non-base faces. Since the cube has six faces in total, the lateral surface area is:
Lateral surface area = 4 * (side length)²
Lateral surface area = 4 * x²
Lateral surface area = 4 * (√(35/8))²

To find the solution for ( f + g ) ( 2 ), evaluate the solution above for 2.
Since ( f + g ) ( x ) = x2
+ 4x then;
( f + g ) ( 2 ) = 22
+ 4(2)
= 4 + 8
= 12
Example 2. Given f ( x ) = 2x – 5 and g ( x ) = 1 – x find ( f – g ) ( x ) and ( f – g ) ( 2 ).
Solution
Step 1. Find ( f – g ) ( x ).
( f – g ) ( x ) = f ( x ) – g ( x )
= ( 2x – 5 ) – ( 1 – x )
= 2x – 5 – 1 + x
= 3x – 6
Step 2. Find ( f – g ) ( 2 ).
( f – g ) ( x ) = 3x – 6
( f – g ) ( 2 ) = 3 (2) – 6
= 6 – 6
= 0
Step-by-step explanation:
Which of the following takes all the correlations found in studies of a particular relationship and calculates a weighted average of them?A. Human resource managementB. Resource-based viewC. Meta-analysisD. Strategic managementE. Method of intuition
Option C is correct. Meta-analysis takes all of the correlations found in studies of a particular relationship and calculates a weighted average of them.
In order to identify results on a broad scale, meta-analysis looks for common threads among various studies and applies weights to them. In essence, it expands on the numerous research that might be conducted on a certain relationship topic. For instance, one particular relationship might be investigated using various methods at various points in time. A meta-analysis attempts to compile all of these studies, assign weights to each study, and then determine the outcomes that are on a meta-level, or bigger picture, after taking into account all of the various correlations.

Answer:
46.8 cm²
Step-by-step explanation:
3.9 x 6 = 23.4 (We are multiplying by 6 because there are 6 tiles)
23.4 x 2 = 46.8 (We are multiplying by 2 because when Suki is adding more tiles, she makes a hexagon double the side lengths.)
