Hi!

The answer is no, because the y values have no pattern, nor are they proportional with the x values.

Hope this helps! :)

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.

One argument against the American standard system of measurement is a lesser degree of accuracy than that of the metric system.

densk [106]

In this item, we are to divide one (1) inch into 16 equal parts to be able to conclude that American standard system is less accurate than the metric system.
16 parts of 1 inch = 1 inch / 16 = 0.0625 inch

This in itself is already a proof enough that there are 4 decimal places after the decimal point which makes this hard to properly measure.

Whereas, if we are to divide a centimeter into the millimeters, we will have 10 equal parts and that would be 1 mm = 0.1 cm.

The number above only has one decimal place and the level of accuracy should be higher.

Find the ordered pairs for the x- and y-intercepts of the equation 3x − 2y = 18 and select the appropriate option below.

olasank [31]

<h2>Greetings!</h2>

Answer:

Step-by-step explanation:

Y intercept:

Simply substitute all the x values with 0:

When x = 0:

3(0) - 2y = 18

Move the - 2y over to the other side making it a +2y:

0 = 18 + 2y

Move the +18 over to the other side making it a -18:

-18 = 2y

Divide both sides by 2:

$\frac{-18}{2} = \frac{2y}{2}$

-9 = y

So y intercept is:

X - intercept:

Simply substitute all the Y's with 0:

3x - 3(0) = 18

3x = 18

Divide both sides by 3:

$\frac{3x}{3} = \frac{18}{3}$

x = 6

So the X intercept is:

This means that your guess of B is correct.
