A mother function is the simplest function of a family of functions.
Answer: By cross multiplication.
Step-by-step explanation: Given product is 3 × 292.
We know that after simple multiplication, we get 3 × 292 = 876.
Now, to check division with multiplication, either we need to divide 876 by 3 to get the answer 292,
or
we need to divide 876 by 292 to get the answer 3.
We will do that as follows -

Thus, doing cross-multiplication, we arrive at our conclusion.
Answer:
Step-by-step explanation:first you multiply 0.76 by 14then multiply 0.68 by 8 then multiply 6.71 by 4. After you get your answer for each one you add them by the cost of each one
Answer:
с. A matched pairs t-interval for a mean difference.
Step-by-step explanation:
With the sample, we will have possession of the sample mean and of the sample standard deviation, which means that the t-distribution will be used.
We want to find the mean number of back problems for each sample, and estimate the difference. Since the groups are similar, with only the positions in which they work being different, we have matched pairs. So the correct answer is given by option c.
