Slope of a Line passing through two points [tex](x_1 , y_1)[/tex] and [tex](x_2 ,y_2)[/tex] equal [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

1. Data is approx bell-shaped and symmetric

2. Median is between 150 to 175

A histogram is a graphical representation of a frequency distribution of a set of continuous data. It is used to display the shape of the data and to show how frequently certain values occur within a given range or interval.

In a histogram, the x-axis represents the range or interval of the data, and the y-axis represents the frequency of occurrence of values within each interval.

The data is divided into a set of bins or intervals, and the height of each bar on the histogram represents the number of data points that fall within that particular bin. The bars of the histogram are typically drawn adjacent to each other, with no gaps between them, to emphasize the continuity of the data.

Therefore, from the histogram used to represent the given data, it can be seen that the data is symmetric and also the median has the values between 150 to 175

The calculated value of the derivative f'(x) at x = -2/3 if f(x) = 5x√(x + 1) is f'(-2/3) = 0

Given the function

f(x) = 5x√(x + 1)

Factor out 5

So, we have

f(x) = 5[x√(x + 1)]

The derivative is then calculated using the following chain rule

f'(x) = 5[du/dx * dy/du]

When differentiated, we have

f'(x) = 5[√(x + 1) + x/2[√(x + 1)]]

This gives

f'(x) = 5[3x + 2/2[√(x + 1)]]

So, we have

f'(x) = [15x + 10]/[2√(x + 1)]

Substitute -2/3 for x

f'(-2/3) = [15(-2/3) + 10]/[2√((-2/3) + 1)]

Evaluate

f'(-2/3) = [0]/[2√1/3]

Evaluate the quotient

f'(-2/3) = 0

The equation that can be solved to predict the number of times Harris will spin a sum less than 10 is B) 12/500 = x/15

Harris should expect to spin a sum of 10 or greater 240 times.

It should be noted that to predict the number of times Harris will spin a sum less than 10, we need to find the probability of getting a sum less than 10 and multiply it by the total number of experiments (500).

The possible sums that can be obtained are: 5, 6, 7, 8, 9, 10, 11, and 12. The probability of getting a sum less than 10 is the sum of the probabilities of getting each of these outcomes, which is:

P(sum less than 10) = P(1 and 4, 1 and 5, 2 and 4, 2 and 5, 3 and 4, 3 and 5)

= 6/15 * 2/5

= 4/25

Multiplying this probability by the total number of experiments (500), we get:

Number of times Harris will spin a sum less than 10 = (4/25) * 500 = 80

Therefore, the correct equation to predict the number of times Harris will spin a sum less than 10 is: 12/500 = x/15

Part B: Based on the information, the possible outcomes that give a sum of 10 or greater are: 10, 11, and 12. The probability of getting a sum of 10 or greater is the sum of the probabilities of getting each of these outcomes, which is:

P(sum of 10 or greater) = P(1 and 9, 2 and 8, 3 and 7, 4 and 6, 5 and 5, 6 and 4, 7 and 3, 8 and 2, 9 and 1, 8 and 3, 7 and 4, 6 and 5)

= 12/15 * 3/5

= 36/75

= 12/25

Multiplying this probability by the total number of experiments (500), we get:

Number of times Harris should expect to spin a sum of 10 or greater = (12/25) * 500 = 240

Therefore, Harris should expect to spin a sum of 10 or greater 240 times.

the measurement of the fourth angle of the quadrilateral is 95 degrees.

To find the measurement of the fourth angle of a quadrilateral when the measures of three angles are given, we can use the fact that the sum of the measures of the angles in a quadrilateral is 360 degrees.

Let's denote the measure of the fourth angle as x. Then we can write an equation:

80 + 120 + 65 + x = 360

Simplifying this equation, we get:

x = 360 - 80 - 120 - 65 = 95

Therefore, the measurement of the fourth angle of the quadrilateral is 95 degrees.

In light of this, the cylinder's total surface area falls between approximately 1017.9 cm²and 1357.2 cm².

A cylinder's total surface area is equal to the sum of all of its faces' surface areas. The cylinder's total surface area—the sum of its curved and circular areas—has a radius of "r" and a height of "h." The entire surface area of the cylinder is calculated as follows:

Total Surface Area of Cylinder = 2r (h + r) square units.

The three-dimensional shape of a cylinder is made up of two parallel circular bases connected by a curved surface. It is seen as a prism since its base is a circular. It is frequently used as a container and can either be solid or hollow 13.

The following formula can be used to get a cylinder's total surface area:

A = 2πr² + 2πrh

where r is the cylinder's base's radius, h is the cylinder's height, and is a mathematical constant roughly equal to 3.14159.

Yet, we can locate a variety of potential surface areas using the provided information. With the assumption that the radius is equal to the feedback's half (9 cm), we can

after which, we can determine the surface area as follows:

A = 2π(9)² + 2π(9)(18) (18)

A=  2π(81) + 2π(2916)

A ≈ 1017.9 cm²

The surface area can be calculated as follows if we assume that the radius is equal to two-thirds of the feedback (i.e., r = 12 cm):

A = 2π(12)² + 2π(12)(18) (18)

A ≈ 1357.2 cm²

    [tex]P=2+4+2+1+4+5=18cm[/tex]

Answer: the slower bus travels at 55 miles per hour and the faster bus travels at 73 miles per hour.

Step-by-step explanation:

distance = rate x time

768 = 6x + 6(x + 18)

Simplifying this equation, we can distribute the 6 on the right-hand side:

768 = 6x + 6x + 108

Combining like terms, we get:

768 = 12x + 108

Subtracting 108 from both sides:

660 = 12x

Dividing both sides by 12:

x = 55

So the slower bus is traveling at 55 miles per hour. To find the speed of the faster bus, we can add 18:

x + 18 = 55 + 18 = 73

Answer: one is 55 and the other is 73

Step-by-step explanation:

lets say x is for the slower bus. for every hour the become x+x+18

and this is happening for 6 hours so its is 6(2x+18)=768

x=55

x+18=73

CB = 8 cm * tan(25°)

≈ 3.45 cm

To find the segment CB, we need to use the tangent of the angle α (25°). We also need to know the length of the segment AB, which is 8 cm. To solve for CB, we use the equation CB = 8 cm * tan(25°).

The coordinate of point B' is (8, 3) after reflecting point B (8, -3) over the x-axis.

A reflection is an involution: when applied twice in succession, every point returns to its original location, and every geometrical object is restored to its original state.

When a point is reflected over the x-axis, its y-coordinate changes sign while its x-coordinate remains the same.

Therefore, to find the coordinates of point B' after reflecting point B over the x-axis, we simply need to change the sign of the y-coordinate of point B.

Starting with point B at (8, -3), reflecting over the x-axis changes the sign of the y-coordinate, so the new point B' is at:

B' = (8, 3)

Therefore, the coordinate of point B' is (8, 3) after reflecting point B (8, -3) over the x-axis.

Answer:

Step-by-step explanation:

Let's call the weight of Karen's package "w" in pounds.

For the first courier, the cost is given by:

Cost = 20 + 2w

For the second courier, the cost is given by:

Cost = 12 + 3w

We know that these costs are equivalent, so we can set them equal to each other:

20 + 2w = 12 + 3w

Simplifying this equation, we get:

8 = w

So the weight of Karen's package is 8 pounds.

To find the cost, we can plug this weight into either of the equations above:

For the first courier:

Cost = 20 + 2(8) = 36

For the second courier:

Cost = 12 + 3(8) = 36

So it will cost Karen $36 to deliver her package, and the weight of the package is 8 pounds.
