Answer:

c. 106 million

Step-by-step explanation:

A = number of people in the sample that use public transportation 5 or more days per week

A = 2,067,153

B = number of people total in the sample

B = 4,295,280

C = proportion of those in the sample that use public transportation 5 or more days per week

C = A/B

C = (2,067,153)/(4,295,280)

C = 0.48126 approximately

Multiply this value by the figure 220 million to compute the estimated number of people who use public transportation 5 or more days per week

C*(220 million) = 0.48126*(220 million) = (0.48126*220) million = 105.8772 million = 106 million

kondaur [170]

To the nearest percentage point, what percentage of students who play a sport don’t play a musical instrument?

First, using the information given, fill out the chart with the rest of the data (in the image attached)

Then find the number of students who play a sport and don’t play a musical instrument, which in the chart is 11

Place 11 over the total: $\frac{11}{25}$ and convert to a percentage:

44%

Question 2

Answer:

Please check the explanation.

Step-by-step explanation:

Calculating the area of the outer rectangle:

Given

The length outer rectangle = l = 3x - 1

The width of outer rectangle = w = 5x + 2

Thus,

The area of the outer rectangle:

$A = wl$

$= (5x + 2) (3x - 1)$

$=5x\cdot \:3x+5x\left(-1\right)+2\cdot \:3x+2\left(-1\right)$

$=5\cdot \:3xx-5\cdot \:1\cdot \:x+2\cdot \:3x-2\cdot \:1$

$=15x^2+x-2$

Calculating the area of the inner rectangle:

Given

The length inner rectangle = l = x + 7

The width of inner rectangle = w = x

Thus,

The area of the outer rectangle:

A = wl

= x(x+7)

= x² + 7

Calculating the area of the shaded region:

As

The area of the outer rectangle = 15x² + x - 2

The area of the inner rectangle = x² + 7

The area of the shaded region can be determined by subtracting the area of the inner rectangle from the area of the outer rectangle.

Thus,

shaded region Area = Outer Rectangle Area - Inner Rectangle Area

= 15x² + x - 2 - (x² + 7)

= 15x² + x - 2 - x² - 7

= 14x² + x - 9

Therefore, the Area of the shaded region is: 14x² + x - 9
