Volume of square pyramid = (base area) * h/3
= (8*8) *10/3
=64 * 3.333»
=213.33cm3
Btw " * " means multiply
and " »" means continued

Answer: a. confidence level.
Step-by-step explanation:
Given : A newspaper provided a "snapshot" illustrating poll results from 1910 professionals who interview job applicants.
i.e. Sample size : n= 1910
The illustration showed that 26% of them said the biggest interview turnoff is that the applicant did not make an effort to learn about the job or the company.
The point estimate of the proportion of job applicants said the biggest interview turnoff is that the applicant did not make an effort to learn about the job or the company = p=0.26
[Note : The point estimate of the population proportion is basically the sample proportion.]
The margin of error was given as plus or minus 3 ±3 percentage points.
But confidence level is necessary to describe the margin of error .
A confidence interval tells how sure you are about the margin of error .
Thus , the important feature of the poll was omitted = confidence level
Answer:
<em>The products did cost $173.9 in 2010</em>
Step-by-step explanation:
<u>Exponential function</u>
Two variables y and x are related as an exponential function if they comply:
where C is the initial value of F, r is the ratio, and k is a proportional constant.
The situation described in the question is modeled as
Where F is the final value of the cart of groceries in 2010, C = $150 is its value in 2005, r is the yearly rate of increase. n is the number of years
. So
If we set n=5 (from 2005 to 2010):
The products did cost $173.9 in 2010
