The circumference is found by multiplying mc005-1.jpg by the diameter.
Remember - Circumference = pi r^2
Answer:
The sample proportion is 0.36095.
Step-by-step explanation:
A confidence interval has two bounds, a lower bound and an upper bound.
The sample proportion is the halfway point betwen those two bounds, that is, the sum of those bounds divided by 2.
In this problem, we have that:
Lower bound: 0.2987
Upper bound: 0.4232
What is the sample proportion?
(0.2987 + 0.4232)/2 = 0.36095
The sample proportion is 0.36095.

Last term in each binomial:
Add them all together.
Simplify.
This load will weigh
1.5 TONS ALTOGETHER.
So, the truck is delivering a
ton of cement blocks, and a
of bricks. To find how much this load weighs, we'd have to add the two fractions together, which proves to be quite easy, because the denominators are already the same, so we wouldn't have to change anything.
+
=
And now, we would want to convert that fraction into a whole number, or at least a decimal, to find how many tons the truck is carrying. So we would divide. Once the work is done, here is what would happen:
12 ÷ 8 = 1.5
And there's your answer. The truck is carrying
1.5 TONS.
True, because they make up the two line segments make up the right angle
