Answer:

No. it does not

Step-by-step explanation:

(i assumed you meant 2x+7y=10)

1.) 2(2)+7y=10

2.)2(2)+7(1)=10

3.)4+7=10

4.)11=10

Answer:

2x+7y>=10

Replace x and y with 2 and 1

2*2+7*1>=10

2*2=4

7*1=7

4+7>=10

7+4=11

2x+7y>=10 is a true statement

Because 11 is greater than 10 and it doesnt have to be equal to 10 as long as its greater.

What is the formula for a confidence interval?

ikadub [295]

Answer:

a) The formula is given by mean $\pm$ the margin of error. Where the margin of error is the product between the critical value from the normal standard distribution at the confidence level selected and the standard deviation for the sample mean.

b) $\bar X \pm z_{\alpha/2}\frac{\sigma}{\sqrt{n}}$

Step-by-step explanation:

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

If the distribution for X is normal or if the sample size is large enough we know that the distribution for the sample mean $\bar X$ is given by:

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})$

Part a

The formula is given by mean $\pm$ the margin of error. Where the margin of error is the product between the critical value from the normal standard distribution at the confidence level selected and the standard deviation for the sample mean.

Part b

The confidence interval for the mean is given by the following formula:

$\bar X \pm z_{\alpha/2}\frac{\sigma}{\sqrt{n}}$

What is the equation of the line graphed?

miv72 [106K]

Answer: 3x -2
Because i know as soon as the line goes through the y-axis that number is your y-intersect and for the slope from the first point to the second point you go up 3 and over 1 and 3/1 is equal to 3 which gives your answer y=3x-2
