One of the questions in the Pew Internet & American Life Project asked adults if they used the Internet, at least occasional

Marizza181 [45]

Answer:

Part (a) The point estimate of the proportion of adults aged 18 to 29 who use the Internet is 0.9498.

Part (b) The point estimate of the proportion of adults aged 30 to 49 who use the Internet is 0.8896.

Part (b) Estimate of the proportion of population who use the Internet is 0.7624.

Step-by-step explanation:

Consider the provided information.

Part (a) point estimate of the proportion of adults aged 18 – 29 who use the Internet

The results showed that 454 out of 478 adults aged 18-29 answered yes;

$\hat p=\frac{454}{478}=0.9498$

The point estimate of the proportion of adults aged 18 to 29 who use the Internet is 0.9498.

Part (b) Develop a point estimate of the proportion of adults aged 30-49

741 out of 833 adults aged 30-49 answered yes;

$\hat p=\frac{741}{833}=0.8896$

The point estimate of the proportion of adults aged 30 to 49 who use the Internet is 0.8896.

Part (c) Suppose your target population of interest is that of all adults (18 years of age and over). Develop an estimate of the proportion of that population who use the Internet.

$\hat p=\frac{454+741+1058}{478+833+1644}$

$\hat p=\frac{2253}{2955}=0.7624$

Estimate of the proportion of population who use the Internet is 0.7624.

Use counters to find the quotient and remainder for 36 divide a by 8

koban [17]

First, you take 36 counters and spread them out. You then separate them into groups of 8 and any left that cannot be separated into groups of 8 are the remainders. When you do this, you will find that you are able to separate 36 into 4 groups of eight, and you will get a remainder of 4, so your answer is 4 remainder 4

I'm really stuck on this math problem. I never learned this in school. Can someone please help me out? Thank you

romanna [79]

Hehe, these are fun to do. There are two ways to do this kind of problem. You can use the pythagorean theorem or we can use the distance formula.
Distance formula:
$d= \sqrt{(x2-x1)^2+(y2-y1)^2}$

Pythagorean Theorem:
$a^2+b^2=c^2$

Distance formula is better if you're finding distance between two coordinates. The Pythagorean Theorem only really works for independent values. If I had 2 sides of a triangle, and I needed to find the third, I'd use this equation to find it. In this case, we'll use the distance formula.

I'll work the first one out for you:
x1 y1 x2 y2
(3, 2) & (7, 4)

$d= \sqrt{(7-3)^2+(4-2)^2}$
v
$d= \sqrt{(4)^2+(2)^2}$
v
$d= \sqrt{(16+4}$
v
$d= \sqrt{20}$

There's your answer!
