Answer:

Step-by-step explanation:

10 - 4m + 7m = m - 10

Simply both sides:

10 + -4m + 7m = m + -10

Combine like terms:

( -4m + 7m) + (10) = m - 10

3m + 10 = m -10

3m + 10 = m - 10

Subtarct m from both sides:

3m + 10 - m = m - 10 - m

2m + 10 = -10

Subtract 10 from both sides:

2m + 10 - 10 = -10 - 10

2m = -20

Divide both sides by the 2:

2m/2 = -20/2

m = -10

<u>Answer =====> m = -10</u>

How many weeks of data must be randomly sampled to estimate the mean weekly sales of a new line of athletic footwear? We want 98

Irina18 [472]

Answer:

$n=(\frac{2.33(1400)}{400})^2 =66.50 \approx 67$

So the answer for this case would be n=67 rounded up

Step-by-step explanation:

Information given

$\bar X$ represent the sample mean for the sample

$\mu$ population mean

$\sigma=1400$ represent the sample standard deviation

n represent the sample size

Solution to the problem

The margin of error is given by this formula:

$ME=z_{\alpha/2}\frac{\sigma}{\sqrt{n}}$ (a)

And on this case we have that ME =400 and we are interested in order to find the value of n, if we solve n from equation (a) we got:

$n=(\frac{z_{\alpha/2} \sigma}{ME})^2$ (b)

The critical value for 98% of confidence interval now can be founded using the normal distribution. And the critical value would be $z_{\alpha/2}=2.33$ , replacing into formula (b) we got:

$n=(\frac{2.33(1400)}{400})^2 =66.50 \approx 67$

So the answer for this case would be n=67 rounded up

What is the x-intercept for the following linear equation:

Alexandra [31]

The "x-intercept" occurs when y=0, because it is at this point that the equation touches the x axis. So if you plug in y=0 into the equation you can solve for the x coordinate.

4x-2(0)-8=0

4x-8=0

4x=8

x=2

So the x-intercept is the point (2,0)
