Minimum required sample size for a desired margin of error and confidence level when it is a proportion problem: n = (z2÷margin of error2)*p-hat*q-hat

The maximum value of p-hat*q-hat occurs where p-hat = .5 (found by taking the derivative of (p-hat)*(1-p-hat) and setting it equal to 0 to find the maximum. n = ( 2.5762( for 99% confidence interval)÷.0482 )*.5*.5 = 720.028 or 721

Write the equation of the line that<br> Passes through (-9,4) and 10,-2)
adell [148]

Answer: The first thing we need to do is find the slope--the rise over run. We can find it by using the formula:

(y2 - y1) / (x2 - x1), that is we subtract the x an y values of our two points and then divide:

(-4 - -10) / (9 - 9)

(-4 + 10) / (9 - 9)

6 / 0

We cannot divide by 0. Our slope is essentially infinity, or a straight line up and down. This means we take a look at the x-coordinate: 9. This means our equation is:

x = 9

because no matter what we use for y, x will always stay at 9

Step-by-step explanation:

also you pfp is cute as hell girl!
