tatyana61 [14]

Well what were given:
1 inch = 30 feet

The drawing of the building of this problem has the height of 1.25 inches and base of 0.75 inches.

Actual height:
1.25 inches * 30 feet/inch = 37.50 feet

Actual base:
0.75 inches * 30 feet/inch = 22.50 feet

So in this problem the answer would be "A" 22.50 Aka 22.5 For the building. Hope this helps you! (:

A survey of 250 homeless persons showed that 14 were veterans. Find a point estimate for the population proportion of homeless p

snow_lady [41]

Answer:

$\hat p =\frac{14}{250}= 0.056$

And for this case that represent the 5.6% of the homeless persons who are veterans

Step-by-step explanation:

We know that in a survey of 250 homeless persons 14 were veterans. We can find the estimated proportion of homeless persons who are veterans with the following formula:

$\hat p =\frac{X}{n}$

The last one is an unbiased estimator of the true population proportion p

And replacing the info given we got:

$\hat p =\frac{14}{250}= 0.056$

And for this case that represent the 5.6% of the homeless persons who are veterans

How does tripling the side lengths of a right triangle affect its area?)

kap26 [50]

The area of the triangle will then be 9 times as great.

The formula of the area of a triangle is 1/2bh, so if the base has been tripled and the height has been tripled, you're essentially multiplying 3 to the original equation twice (3 x 3 = 9).
