In a class of students, the following data table summarizes how many students play an instrument or a sport. What is the probability that a student chosen randomly from the class plays a sport or an instrument?

Answer:

4% compounded yearly

Step-by-step explanation:

20 / 500 = 0.04

0.04 * 100 = 4%

Answer:

Since figure is not given, assume drawing a rectangle and label it from left top to right top as A and B. Similarly label it as C and D from bottom left to right. Draw a semicircle starting from C to D inside the rectangle.

You are asked to find area of shaded region which I assume is semicircular part.  

Area of a circle is determined by    Pi × r ^2

r is the radius of circle which is half of diameter. The diameter of circle is same as width of rectangle. So radius = 7/2 = 3.5 mm And area of shaded region is

                         1/2(Pi×r^2) = 1/2(3.14×3.5^2) = 19.2325 sq mm

Step-by-step explanation:

1) Area of each circle = 0.5625π

There are 2 identical circles in the cylinder.

So the total area of all the circles is;  1.125π square inches

2) One side of the rectangle is; 1.5π

The other side of the rectangle is; 4 inches

The area of the rectangle is approximately; 6π square inches

3) The total area of the can is; 7.125π square inches

We can see that the can is broken down into two circles with one atop and one beneath the rectangle. Thus;

1) Area of Circle on top and at bottom = πr² = π * 0.75²

Area of each circle = 0.5625π

There are 2 identical circles in the cylinder.

So the total area of all the circles is 2(0.5625π) =  1.125π square inches

2) One side of the rectangle is; 2πr = 2 * π * 0.75 = 1.5π

The other side of the rectangle is; 4 inches

The area of the rectangle is approximately; 4 * 1.5π = 6π square inches

3) The total area of the can = 6π square inches + 1.125π square inches = 7.125π square inches

Given:

The bakers at Healthy Bakery can make 170 bagels in 2 hours.

To find:

How many  bagels can they bake in 14 hours and the rate per hour.

Solution:

We have,

Number of bagels the bakers can bake in 2 hours = 170 bagels

Number of bagels the bakers can bake in 1 hours = [tex]\dfrac{170}{2}[/tex] bagels

                                                                                   = 85 bagels

Therefore, the average rate is 85 bagels per hour.

Number of bagels the bakers can bake in 14 hours = [tex]14\times 85[/tex] bagels

                                                                                    = 1190 bagels

Therefore, the bakers can bake 1190 bagels in 14 hours.

Answer:

Median = 80

Mode = 85

The mode

Step-by-step explanation:

Given the data :

45 45 50 50 55 60 70 75 75 80 80 85 85 85 85 90 95 95 95 100

Rearranged data :

45, 45, 50, 50, 55, 60, 70, 75, 75, 80, 80, 85, 85, 85, 85, 90, 95, 95, 95, 100

The mean score :

ΣX / n ; n = sample size = 20

ΣX = 1500

Mean = 1500 / 20 = 75

Mode = most frequently occurring = 85 ( frequency of 4)

Median = 0.5(n + 1)th term

Median = 0.5(20 + 1)th term

Median = 0.5(21) th term

Median = 10.5th term = (10 + 11)th term / 2

Median = (80 + 80) / 2 = 160 / 2 = 80

2.) The mode

Answer:

30° and 150°

Step-by-step explanation:

supplementary means that the sum of the measures = 180

let's say 1 angle is labled ∠A and the other ∠B

m∠A + m∠B = 180°

however, m∠A = 5 * m∠B

so, by substituting that:

5*m∠B + m∠B = 180°

6*m∠B = 180°

m∠B = 30°

m∠A = 150°

The activity rate for the Order Size activity cost pool under activity-based costing is closest to A. $59.78 per MH.

The activity rate under activity-based costing is also called the cost driver rate.

The activity rate per cool pool can be computed by dividing the cost pool total cost by the cost driver total requirements.

Order size Overhead Costs = $579,866

Machine Hours (MHs) = 9,700

Activity rate for the Order Size = $59.78 ($579,866/9,700)

Thus, the activity rate for the Order Size activity cost pool under activity-based costing for Chrzan Inc. is closest to A. $59.78 per MH.

For the following graph, it is found that:

A graph represents a function if it has no vertically aligned points, that is, each value of x is mapped to only one value of y.

For the graph in this problem, the statement is true, hence the graph is a function.

The inverse of a graph will be a function if the original function is one-to-one, that is, each value of y is mapped to only one value of x, meaning that the graph has no horizontally aligned points.

This is also true for this function, hence the inverse is a function.

The correct answer is $170.4

Explanation:

The total Georgie spent is equal to the money spent on clothes ($160) added to taxes (6.5% of the price of the clothes). Now, to calculate the money spend on taxes follow this process:

1. Divide the total of money spent on clothes into 100 (this number represents 100%)

160 ÷ 100 = 1.6

2. Multiply this number by the specific percentage (6.5)

1.6 x 6.5 = $10.4 (This is the money spent on taxes)

Finally, add the value of taxes and the price of the clothes:

$160 + $10.4 = $170.4
