42 in base 5 is written as 132.

In mathematics, we often use different number systems, also known as bases, to represent numbers. The most commonly used number system is the decimal system, which is base 10. However, there are many other number systems, such as base 2, base 5, base 8, and so on. Each base system has its own set of digits that are used to represent numbers. In this explanation, we will focus on base 5 and how to convert the number 42 to base 5.

To convert a number to a different base system, we need to first understand the concept of place value. Place value is the value of a digit based on its position in a number. In the number 42, the digit 4 is in the tens place and has a value of 40 (4 x 10). The digit 2 is in the ones place and has a value of 2.

In base 5, we only have 5 digits to work with: 0, 1, 2, 3, and 4.

To convert the number 42 to base 5, we need to divide 42 by 5 and record the remainder.

We then divide the quotient by 5 again and record the remainder, and so on, until the quotient is 0.

42 ÷ 5 = 8 remainder 2

8 ÷ 5 = 1 remainder 3

1 ÷ 5 = 0 remainder 1

To convert these remainders into the corresponding digits in base 5, we simply read them from bottom to top. Therefore, 42 in base 5 is written as 132.

The conversion factor for changing centimetres to feet is 0.032. Thus, the conversion of 150 centimetres in feet is equals to the 4.92 feet.

A conversion factor is a number used to convert one set of units into another set of units by multiplication or division. If conversion is necessary, a conversion factor suitable for equivalent value must be used. For example, to convert meters to centimetres, the appropriate conversion value is 100 centimetres equal 1 meter. It includes converting a value from inches to millimeters, for distance from miles to kilometers, feet or other units. How to convert centimeters to feet : One meter is a measure of length and equals approximately 3.28 feet. Thus conversion factor is 3.28 feet. So,150 meters

= 150 × 3.28 feet

= 492 feet --(1)

But we need to convert 150 centimeters to feet. So, change meters to centimeters. As you know, 1 meter = 100 centimeters, so 150 meters = 15000 centimeters --(2). Now from equations (1) and (2),

15000 centimeters = 492 feet,

Divide both parts by 100,

=> 150 centimetres = (492/100 ) feet

When tossing a fair coin, the possible outcomes are a head (H) or a tail (T), each with a probability of 1/2.

To find the probability of getting at least one head in two coin tosses, we can first find the probability of getting no heads (i.e., two tails) and then subtract that from 1 to get the probability of getting at least one head.

The probability of getting two tails is (1/2) * (1/2) = 1/4, since the probability of getting a tail on the first toss is 1/2 and the probability of getting a tail on the second toss is also 1/2, and we multiply these probabilities together to get the joint probability.

Therefore, the probability of getting at least one head in two coin tosses is:

1 - 1/4 = 3/4

So the probability of at least one head in two coin tosses is 3/4 or 0.75.

The regression line can be used to determine the strength of a linear association between two variables, as well as to make predictions about the values of y for a given x-value.

The regression line is a type of mathematical model used to describe the relationship between two variables, typically denoted as x and y. The regression line is a straight line that best fits the data points of the two variables. This line can be used to make predictions about the values of y for a given x-value.

The equation of the regression line is y = mx + b, where m is the slope of the line, and b is the y-intercept. The slope of the line, m, represents the strength of the linear relationship between the two variables. It is calculated by dividing the covariance of the two variables by the variance of the independent variable (x). The y-intercept, b, is the point where the regression line crosses the y-axis. It is calculated by taking the mean of y and subtracting the slope of the line multiplied by the mean of x.

The regression line can also be used to determine the strength of the linear association between two variables. This is determined by calculating the correlation coefficient, which is a measure of how closely two variables are associated. The correlation coefficient is calculated by taking the covariance of the two variables, divided by the product of the standard deviation of each variable. A correlation coefficient of close to 1 indicates a strong positive linear association, while a correlation coefficient of close to -1 indicates a strong negative linear association.

In conclusion, the regression line can be used to determine the strength of a linear association between two variables, as well as to make predictions about the values of y for a given x-value.

The missing side length, C, is approximately 23.53 units.

To find the missing side length in a right triangle, we need to use trigonometry. Given the angle A = 27° and the side length opposite to it, B = 12C, we can follow the following steps to find the missing side length:

1. Locate the angle measured: In this case, we are given angle "A = 27°."

2. Label the sides of the right triangle: Let's label the hypotenuse as H, the side opposite to angle A as O, and the side adjacent to angle A as A. We can choose any side as the hypotenuse, so let's choose H to be the side opposite to angle B.

3. Which side do you know? Which side are you trying to find?: We know the length of side B and are trying to find the length of side C.

4. Decide which trig function (cosine, sine, or tangent) fits the sides chosen in step 3: We are given the length of the opposite side (B) and are trying to find the length of the adjacent side (C), so we will use the tangent function.

5. Write your equation. Fill in the known measurements: The tangent of angle A is defined as the ratio of the length of the opposite side to the length of the adjacent side. So we can write:    tan(A) = B/C

      Substituting the known values, we get:

      tan(27°) = 12/C

6. Create two fractions. Cross-multiply to solve: To solve for C, we can cross-multiply and simplify the equation as follows:

      tan(27°) = 12/C  

      C * tan(27°) = 12          

      C = 12/tan(27°)                                                                                

        Using a calculator, we can evaluate the value of tan(27°) to be approximately 0.5095. Therefore,                                                     

       C = 12/0.5095 ≈ 23.53

Without knowing the scale factor, we can use the ratio of corresponding sides of the two trapezoids to set up an equation and solve for x.

The ratio of the lengths of the corresponding sides of the two trapezoids is: 14.7 cm / 12.6 cm = 4.9 cm / x

To solve for x, we can cross-multiply:

14.7 cm × x

= 12.6 cm × 4.9 cm

Dividing both sides by 14.7 cm, we get:

x = (12.6 cm × 4.9 cm) / 14.7 cm

The sum of ∠A and ∠C is 90°.

Step-by-step explanation:

Interior angles of a triangle sum to 180°.

[tex]\implies m \angle A + m \angle B + m \angle C = 180^{\circ}[/tex]

From inspection of the given right triangle:

Substitute the given angles into the equation and solve for x:

[tex]\implies m \angle A + m \angle B + m \angle C = 180^{\circ}[/tex]

[tex]\implies (2x+1)^{\circ} + 90^{\circ} + (5x+5)^{\circ} = 180^{\circ}[/tex]

[tex]\implies (2x+1)^{\circ} + 90^{\circ} + (5x+5)^{\circ}-90^{\circ} = 180^{\circ}-90^{\circ}[/tex]

[tex]\implies (2x+1)^{\circ} + (5x+5)^{\circ} = 90^{\circ}[/tex]

[tex]\implies 2x+1 + 5x+5 = 90[/tex]

[tex]\implies 2x+ 5x+1 +5 = 90[/tex]

[tex]\implies 7x+6 = 90[/tex]

[tex]\implies 7x+6 -6= 90-6[/tex]

[tex]\implies 7x=84[/tex]

[tex]\implies 7x\div7=84\div7[/tex]

Step-by-step explanation:

A right angled triangle is given to us and we need to find out the value of " x " . The two unknown angles are (2x + 1)° and (5x + 5)° .

We know that, the Angle sum property of a triangle is 180° . So the sum of all the given angles inside the triangle will be 180° .

And as per question one of the angle is 90° . So the sum of other two angles will be 90° .

Hence ,

2x + 1 + 5x + 5 + 90 = 180

7x + 96 = 180

7x = 180 - 96

7x = 84

x = 84/2

x = 12

Hence the value of x is 12 .

The probability of selecting three balls of the same color without replacement is 0.0545, and with replacement is 0.0393. The probability of selecting three balls of different colors without replacement is 0.4591, and with replacement is 0.4968.

(a) To select a set of 3 balls that are all of the same color, we need to choose one of the three colors (red, blue, or green), and then select 3 balls of that color from the urn. There are three ways to choose the color of the balls. For each color, the number of ways to select 3 balls of that color is given by the number of combinations of 3 balls from the set of balls of that color. Thus, the total number of ways to select a set of 3 balls that are all of the same color is:

Number of ways to select 3 red balls + number of ways to select 3 blue balls + number of ways to select 3 green balls

= (5 choose 3) + (6 choose 3) + (8 choose 3)

= 10 + 20 + 56

= 86

The total number of ways to select any set of 3 balls from the urn is given by the number of combinations of 3 balls from the set of 19 balls in the urn:

Total number of ways to select any set of 3 balls = (19 choose 3) = 969

Therefore, the probability that each of the balls will be of the same color is:

P(each ball of the same color) = (number of ways to select 3 balls of the same color) / (total number of ways to select any set of 3 balls)

= 86 / 969

= 0.089

So the probability that each of the balls will be of the same color is approximately 0.089 or 8.9%.

(b) To select a set of 3 balls that are of different colors, we need to choose one ball of each color from the urn. The number of ways to select one ball of each color is given by the product of the number of balls of each color:

Number of ways to select 1 ball of each color = 5 x 6 x 8 = 240

The total number of ways to select any set of 3 balls from the urn is still 969.

Therefore, the probability that each of the balls will be of different colors is:

P(each ball of different color) = (number of ways to select 1 ball of each color) / (total number of ways to select any set of 3 balls)

= 240 / 969

= 0.248

So the probability that each of the balls will be of different colors is approximately 0.248 or 24.8%.

When the balls are selected with replacement, the probabilities remain the same because the probabilities of selecting each ball are unchanged on each draw.

The integral of sec^3(4x) can be found using the substitution method.

Let u = 4x, then du/dx = 4 and dx = du/4

Substitute these values into the integral:

Now we can use the formula for the integral of sec^3(x):

Substitute back in u for x:

Therefore, the integral of sec^3(4x) is (1/8) sec(4x) tan(4x) + (1/8) ln |sec(4x) + tan(4x)| + C, where C is the constant of integration.

Answer:

The major axis of the given ellipse is on the y-axis.

Step-by-step explanation:

The general equation of an ellipse is:

[tex]\boxed{\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1}[/tex]

where (h, k) is the center.

The major axis is the longest diameter of an ellipse, and the minor axis is the shortest diameter of an ellipse.

If a > b the ellipse is horizontal, a is the major radius (parallel to the x-axis), and b is the minor radius (parallel to the y-axis).

If b > a the ellipse is vertical, b is the major radius (parallel to the y-axis), and a is the minor radius (parallel to the x-axis).

The given equation is:

[tex]\dfrac{x^2}{49}+\dfrac{y^2}{81}=1[/tex]

Therefore:

As b > a, the ellipse is vertical.

The major axis is 18 units in length and is parallel to the y-axis.

The minor axis is 14 units in length and is parallel to the x-axis.

Both axes pass through the center of the ellipse.

As the center of the ellipse is the origin, the major axis is on the y-axis and the minor axis is on the x-axis.
