The volumes aren't the same as the first cylinder has a bigger volume.

Based on the information given, it should be noted that the first cylinder has circumference of 11 inches. The radius will be calculated thus:

2πr = 11

2 × 3.14 × r = 11

6.28r = 11

Divide

r = 11 / 6.28

r = 1.75 inches

The volume of the cylinder will be:

= πr²h

= 3.14 × 1.75² × 8.5

= 81.74 inches³

For the second cylinder, circumference is 8.5 inches. The radius will be calculated thus:

2πr = 8.5

2 × 3.14 × r = 8.5

6.28r = 8.5

Divide

r = 8.5 / 6.28

r = 1.35 inches

The volume of the cylinder will be:

= πr²h

= 3.14 × 1.35² × 11

= 63 inches³

Answer:

A rectangle of 10.6 x 11.4 dimensions.

Step-by-step explanation:

(5.3*2)*(5.7*2)=5.3*4*5.7=10.6x11.4.

(a) the mgf of X is M_X(t) = (1 - γ) / (1 - γe^t).

(b) the mean and the variance is E[X] = γ / (1 - γ) and Var(X) = γ / (1 - γ), respectively.

The moment generating function (mgf) of a random variable X is defined as M_X(t) = E[e^(tX)], where t is a real number and E[X] denotes the expected value of X.

To find the mgf of X, we can first calculate the expected value of e^(tX) for each possible value of X:

E[e^(tX)] = (1 - γ)e^(t0) + γe^(t1) + (1 - γ)e^(t2) + γe^(t3) + ...

This infinite series can be simplified using the geometric series formula:

E[e^(tX)] = (1 - γ) + γe^t + (1 - γ)e^(2t) + γe^(3t) + ...

= (1 - γ) / (1 - γe^t)

Thus, the mgf of X is M_X(t) = (1 - γ) / (1 - γe^t).

To find the mean and variance of X, we can use the following formulas:

Mean of X: E[X] = ΣxP(X=x) = ΣxfX(x)

= 0(1 - γ) + 1γ + 2(1 - γ) + 3γ + ...

= γ / (1 - γ)

Variance of X: Var(X) = E[X^2] - (E[X])^2

= Σx^2fX(x) - (E[X])^2

= 0^2(1 - γ) + 1^2γ + 2^2(1 - γ) + 3^2γ + ... - (γ / (1 - γ))^2

= γ / (1 - γ)^2 - (γ / (1 - γ))^2

= γ / (1 - γ)

Therefore, the mean and variance of X are E[X] = γ / (1 - γ) and Var(X) = γ / (1 - γ), respectively.

The perimeter and area of a rectangle are (5,6) and (6,5).

The perimeter method for a rectangle states that P = (L + W) × 2, where P represents perimeter, L represents length, and W represents width. when you are given the size of a square form, you may simply plug within the values of L and W into the formula that allows you to clear up for the fringe.

A perimeter is a closed course that encompasses, surrounds, or outlines either a two-dimensional shape or a one-dimensional period. The perimeter of a circle or an ellipse is known as its circumference. Calculating the perimeter has several practical programs.

The perimeter P of a rectangle is given by means of the method, P=2l+2w, in which l is the period and w is the width of the rectangle. The place A of a rectangle is given with the aid of the components, A=lw, wherein l is the length and w is the width.

The perimeter of the rectangle:

P=2l+2w=22

divide 2 into both sides

l+w=11 -------------> (1)

w=11-l

Area of the rectangle:

l*w=30

l(11-l)=30

11l-l^2-30=0

l^2-11l+30=0

By factor method,

(l-5)(l-6)=0

l=5,6.

Substitute this value in w,

l=5 implies w=6

l=6 implies w=5

There we have two solutions.

Answer x=12

Step-by-step explanation:

5/2x-7=3/4x+14

      +7.         +7

5/2x=3/4x+21

-3/4x -3/4x

5/2-3/4=7/4x

7/4x=21.         since there's a fraction on one side, multiply 4 with 21

7x=84

divide and you'll get x=12

\( \frac{5}{2} x(4) - 7(4) = \frac{3}{4} x(4) + 14(4) \\ 10x - 28 = 3x + 56\)

\(10x - 3x = 56 + 28 \\ 7x = 84 \\ x = \frac{84}{7} \\ x = 12\)

\( \large \boxed {x = 12}\)

Answer:

x = 5

y = 1

Step-by-step explanation:

2x - y = 9

3x + 4y = 19

We multiply the first equation by 4

8x - 4y = 36

3x + 4y = 19

11x = 55

x = 5

Now we put 5 in for x and solve for y

2(5) - y = 9

10 - y = 9

-y = -1

y = 1

Let's Check the answer

2(5) - 1 = 9

10 - 1 = 9

9 = 9

So, x = 5 and y = 1 is the correct answer.

Z score is a statistical that corresponds to the standarization of the regular score to a normal dsitribution

The formula for Z score is Z = [X - mean ]./ (standar deviation)

Here X = 930.00; mean = 900.00; and standard deviation = 15.00

Then, Z = [930.00 - 900.00] / 15.00 = 30.00 / 15.00 = 2.00

Answer: 2.00

The size tray of plants which is the best value for money is large tray.

A small tray of 10 plants costs £2.50

Cost per unit = Total cost / number of plants

= £2.50 / 10 plants

= £0.25 per plant

A medium tray of 40 plants costs £8.40

Cost per unit = Total cost / number of plants

= £8.40 / 40 plants

= £0.21 per plant

A large tray of 90 plants costs £12.60

Cost per unit = Total cost / number of plants

= £12.60 / 90 plants

= £0.14 per plant

Hence, the large tray of 90 plants costs £12.60 is the best buy for your money.

Answer:

165 minutes

Step-by-step explanation:

To solve for the number of minutes that Joaquin played for, we can use this expression:

(let 'a' represent how much time passed from the time Joaquin started playing basketball until the time he arrived at home)

Subtracting 1:10 from each side:

1:10 - 1:10 cancels out to 0, while 3:35 - 1:10 is equal to 2:25.

So, the expression is now:

So, 2 hours and 25 minutes passed.

If we know that 1 hour is equivalent to 60 minutes, we can use this expression to solve for however many minutes are in 2 hours:

Now we need to add on the number of minutes and the time it took him to get home:

Therefore, 165 minutes passed from the time Joaquin started playing basketball until the time he arrived at home.

In statistics, a residual is defined as the difference between the predicted value of an outcome variable and the observed value of that variable. Residuals are used to evaluate how well a regression model fits the data.In order to calculate the residuals for a scatterplot, follow these steps:

Step 1: Plot the data on a scatterplot.

Step 2: Perform a regression analysis on the data to find the equation of the regression line. This equation should take the form y = mx + b, where y is the dependent variable, x is the independent variable, m is the slope of the line, and b is the y-intercept.

Step 3: Using the equation of the regression line, calculate the predicted value of y for each data point in the scatterplot.

Step 4: Subtract each predicted value of y from the actual value of y for each data point in the scatterplot. This difference is the residual for that data point.

Step 5: Plot the residuals on a new scatterplot. The x-axis of this scatterplot should be the independent variable, and the y-axis should be the residual values.

Step6: This scatterplot is called a residual plot.Residuals are useful for identifying patterns in data that the regression model fails to capture. If the residuals are randomly scattered around the horizontal axis, then the regression model is a good fit for the data. If there are clear patterns in the residual plot, then the regression model may not be a good fit for the data and further analysis is required.

1/4π radians is approximately equal to 45 degrees.

To convert a value from radians to degrees, multiply the value by 180/π. For example, to convert π/4 radians to degrees, multiply π/4 by 180/π to get 45 degrees. This conversion is useful for converting angles between the two units of measurement.

Degrees = Radians × 180/π.

Therefore, to convert 1/4π radians to degrees, we have:

Degrees = (1/4π) × (180/π) ≈ 45°

Hence, 1/4π radians is approximately equal to 45 degrees.
