Answer:
(x^2-6)^2
Step-by-step explanation:
The pattern shows multiplication because the earnings are 12 times the number of hours worked in each pair of values.
We are given a graph. The graph shows the number of hours worked versus the earnings in dollars. The values of the x-coordinates are 0, 1, 2, 3, 4, and 5. The corresponding values of the y-coordinates are 0, 12, 24, 36, 48, and 60. We need to find the pattern among these values.
We can see from the data that the values are in a straight line in the graph. The coordinates have the same proportion. The constant of proportionality is calculated below.
k = 12/1 = 12
Hence, the pattern is multiplicative because the earnings are 12 times the number of hours worked for each pair of values.

Answer:
3.625
Step-by-step explanation:
Given a normal distribution :
Average weight = population mean = 172 pounds
Population standard deviation = 29 pounds
Number of samples selected(n) = 64
The standard deviation of the sample also called the standard error is the proportion of the population standard deviation to the square root of the number samples.
Sample standard deviation :
Population standard deviation /√n
= 29 /√64
= 29 / 8
= 3.625
