Answer:

18.4%

Step-by-step explanation:

The formula for rel. freq. is:

Relative Frequency = Class Frequency/n

Where

Class Frequency will be the number of students in the class we are interested in (in 35-38, the number of students is 9)

n is the total number of students [which is 6+7+8+9+10+9= 49]

Putting into formula we get:

Relative Frequency = 9/49 = 0.1837

To get percentage, we need to multiply by 100:

0.1837 * 100 = 18.37%

Rounded to 1 decimal place, that is 18.4%

Answer:

275 ft³

Step-by-step explanation:

Given the ratio of radii of 2 similar figures = a : b , then

ratio of volumes = a³ : b³

Here the ratio of radii = 5 : 2 , so

ratio of volumes = 5³ : 2³ = 125 : 8

Calculate the volume (V) of A using proportion

$\frac{125}{V}$ = $\frac{8}{88}$ = $\frac{1}{11}$ ( cross- multiply )

V = 275 ft³

That is the volume of figure A = 275 ft³
