Step-by-step explanation:
information given
represent the sample mean
represent the population standard deviation
sample size
represent the value that we want to test
represent the significance level for the hypothesis test.
z would represent the statistic
represent the p value for the test
Hypothesis to test
We want to test if the true mean is less than 12, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info given we got:
We can replace in formula (1) the info given like this:

Answer:
It would be $10.
Step-by-step explanation:
The area of part 1 is 15√2 square in, the area of part 2 is 30 square in, and the area of the entire rectangle is (30 + 15√2) square in.
<h3>What is the area of the rectangle?</h3>
It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
The area of part 1 = 5√2×3 = 15√2 square in
The area of the part 2 = 5√2×3√2 = 15×2 = 30 square in
The area of the entire rectangle = area of part 1 + area of part 2
= (15√2 + 30) square in or
= (30 + 15√2) square in
Thus, the area of part 1 is 15√2 square in, the area of part 2 is 30 square in, and the area of the entire rectangle is (30 + 15√2) square in.
