Answer: The percentage of parents who use cloth diapers in the sample is the statistic.
Step-by-step explanation:
- A statistic is the measure of a particular characteristic in the sample which is nothing but a subset of population.
Here, the concern is to estimate the percentage of parents who use cloth diapers.
He took a sample of 125 parents to enquiry whether or not they use cloth diapers.
So, the percentage of parents who use cloth diapers 9in the sampl is the statistic.

The angle swept out is equal to 1/12 of a full rotation is π/6 radians.
r^2 * theta = π/6 * 11.25^2 = 66.268"
Answer:
Volume is about 26.5 in^3
Step-by-step explanation:
The volume = 4/3 pi r^3 where r = the radius.
the radius = 1/2 diameter = 1/2 * 3.7 = 1.85 ins.
So V = 4/3 * 3.14 * 1.85^3
= 26.5084
Answer:
<h3>55 secs</h3>
Step-by-step explanation:
Given the elevation h (in feet) of the balloon modeled by the function h(x)=−6x+330, we can calculate the time it takes the balloon to reach the ground. The hot air balloon hits the ground at h(x) = 0.
Substitute h(x) = 0 into the modeled expression and find x as shown;
h(x)=−6x+330
0 = −6x+330
6x = 330
Divide both sides by 6
6x/6 = 330/6
x = 55 seconds
Hence the hot air balloon hits the ground after 55 seconds
