Answer:
The x is the domain and the y is the range. It's still a function
Step-by-step explanation:
You can do
83 - 5 to find the answer
So that's
78 or
5 + 78 = 83
13: 72.25
14: 52
For 14, you need to split the figure into a triangle and rectangle.

Answer: One sample z test for means
Step-by-step explanation:
From the information given, the sample size is large. It is greater than 30. Again, the population standard deviation is given. This means that the test statistic would be the z score which is determined by the formula
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = population standard deviation
The probability value would be determined from the normal distribution table.
Therefore, the hypothesis test that should be used is
One sample z test for means
