Answer:
The test statistic (z-score) of this one-mean hypothesis test is z=1.823.
Step-by-step explanation:
The null and alternative hypothesis are:
The significance level is 0.05.
The sample size is n=22.
The sample mean is M=157.
The standard deviation is 18.
The z-score can be calculated as:
The test statistic (z-score) of this one-mean hypothesis test is z=1.823.

Step-by-step explanation:
Assuming that the 270° rotation is in a clockwise motion,
A point (a, b) which undergoes such a rotation will have the new point (-b, a).
Since we have A(2, 1),
A' has the coordinates (-1, 2).
Answer:
c = 5.5
Step-by-step explanation:
c represents the grams of carbohydrates
27 is the total number of calories that are received by the granola bite.
4 is the number of calories from 1 gram of carbohydrates and
5 is the number of calories that are received from other ingredients.
Answer of Part a:
5 is the number of calories that are received from other ingredients.
Part b:
take left hand side (LHS) and put values of c = 8 and 3 one by one.
So, LHS becomes:
4 \times 8 + 5 = 37 4 \
times 3 + 5 = 17
So, Priya is correct that neither 8 or 3 could be solution.
Part c:
So, solution to the equation is: c = 5.5
