Answer:
Step-by-step explanation:
We are given the claim.
Claim: The mean weight of male aerobics instructors in a certain city is more than 182 lbs.
Population mean = 182 lbs
The null hypothesis will state that the sample mean is less than or equal to the population mean 182 lbs.
The alternate hypothesis will state that mean weight of male aerobics instructors in a certain city is more than 182 lbs.

The answer can be either y = 1.5 or y = 1 1/2
Trapezoid, height 7, bases 5 and 6, so
area = (1/2) (6 + 5)(7) = 77/2 = 38.5
Answer: 38.5
As a check it's a 7×5 rectangle plus a 7×1 right triangle, so
A = 7×5 + 7×1/2 = 35 + 3.5 = 38.5, good
10-3=7 so 10-7=3 so 7 dollars spent, 3 dollars left.
Hello from MrBillDoesMath!
Answer:
#39 6.1 (approx)
$41 14.6 (approx)
Discussion:
# 39
From plane trigonometry
cos(69) = x/17 or
x = 17 * cos(69) = 6.1 (approx)
#41
sin(59) = x/17 or
x = 17 * sin(59) = 14.6 (approx)
