1) In this problem, the first thing to do is to enlist the categories:
workers time to clean # apartments
8 2h15 12
8 9 x
2) Note that the number of cleaners is the same. So, we can pick the ratios that fall under the category <em>time </em>and <em>#apartments</em>
<em />
We need to convert that 2h 15 into decimal form before setting the ratios:

3) Now, we can set the ratios and solve for x:

Thus, the answer is 48
X is equal to 9
8.599 x 10^9
The answer is 9
We have been given that Grant spent $2.50, $4.00, $4.25, and $3.25 on breakfast in one week. The next week he spent $6 more in total for the 4 breakfasts than the week before. We are asked to find increase in the mean of second week.
Since Grant spent $6 more than last week, we will divide 6 by 4 to get how much mean of second week breakfast expenditures increased with respect to first week expenditures.
Therefore, mean of second week breakfast expenditure will be $1.5 more than first week.
Answer:
Estimate of the standard error of the mean = 0.38 lb
Step-by-step explanation:
We are given the following in the question:
Sample mean,
= 10.87 lb
Sample size, n = 131
Standard deviation, σ = 4.31 lb
We have ti find the estimate of the standard error of the mean.
Formula for standard error:

Putting values, we get,

0.38 lb is the standard error of the mean.
