Answer:
The sample mean is$ 52
The claimed population mean is $58
Step-by-step explanation:
American households spent an average of about $52 in 2007 on Halloween merchandise such as costumes, decorations and candy. This tells you that the sample mean is$ 52.
1500 households were surveyed in 2008 and found an average spending of $58 0n Halloween tell us that the claim's population mean is $58
Answer:
50.24 yards
Step-by-step explanation:
We will use the pythagorean theorem to find hypotenuse of each of the 4 triangles.
Pythagorean Theorem is 
For Spinach area, two of the legs are 8 and 6. Solving for hypotenuse:

For watermelon area, two of the legs are 12 and 8. Solving for hypotenuse:

in red peppers area, the hypotenuse is already given as 15. But we need to find one leg since that will be the leg of the triangle in tomatoes area. Hypotenuse is 15 and one leg is 12, so the other leg is:

So, in tomatoes area, we have one leg 9 and another leg 6. Solving for hypotenuse:

Adding all the four hypotenuses, we get the length of the walkway:
Length of Walkway =
yards
Answer:
The volume of the water in the pool is 1,017 cubic feet
Step-by-step explanation:
we know that
The volume of a cylinder is equal to

we have
----> the radius is half the diameter
Remember that

so

To find out the height of the water, subtract 0.5 feet from the height of the swimming pool

assume

Find the volume of the water


So, basically ..you just multiply
9*9*9*9
