Answer:

C.   37.5%

Step-by-step explanation:

From the table, we know that the relative frequency of Contractors that prefer Glossy finish is 0.18, and the frequency of Contractors is 0.48. Therefore, contractors who prefer the glossy finish represent 0.18/0.48 = 0.375 or 0.375*100 = 37.5% of the total people surveyed.

Assuming that a soap bubble is a perfect sphere, what is the diameter of a bubble containing 1,000 cm^3 of air? Round to the nea
jenyasd209 [6]

Answer:

A is correct

Step-by-step explanation:

In this question, we are concerned with. calculating the diameter of a bubble given the volume of the bubble.

Since we have assumed the bubble to be a perfect sphere, it’s volume V = 4/3 * pi * r^3

Plugging the value of V = 1000cm^3 , we have

1000 = 4/3 * pi * r^3

3000/4pi = r^3

r^3 = 238.732

r = cube foot of 238.732

r = 6.20cm

This is same as 6.2cm
