The area formula depends on the shape your doing. for Ex:(rectangle, A=lenght*height) and Ex2: (trapazoid, A= 1/2h(b1 +b2))
.......In perimeter you just add up all the sides no matter what shape. Except circle is (C= 2(pie)r)

Step-by-step explanation:
This is a question on hypothesis testing.
Population mean based on 30 year average for July was 90 with
a std deviation of 2.1
Sample of 5 shows average 93.5
To check whether sample average = population average
H0: x bar =90
Ha: x bar not equal 90(Two tailed test)
Test statistic = 
=3.73
Since this lies outside the range (-1.96, 1.96) we reject null hypothesis
Hence we cannot say sample mean equals 90
Answer:

Step-by-step explanation:
Here is a function rule that produces an output of 7 for an input of 1.6
f(x) = x + 5.4
when x = 1.6, f(x) = 1.6 + 5.4 = 7
Well, it’s quite surprising to learn that washing and drying may take up to 80 minutes.
