STATISTICS PLEASE HELP
Bingel [31]

Answer:

95

Step-by-step explanation:

If the mean is 400 and the standard deviation 12.5. It means that a range between 375 and 425 is the mean +- 2 standard deviations

400 - 12.5*2 = 375

400 + 12.5*2 = 425

Which means the probability is 95%

When you are looking for +- 1 deviation standard the probability is 68, and for +- 3 the probability is 99.7

There is a more complex explanation based on Z, but assuming you are only applying 68-95-99.7 rule this should be enough.

(x-p)^2=p<br> -9+12x-6x^2=0
Volgvan

Answer:

Step-by-step explanation:

Hello

(x-p)^2=p (I don’t understand)

-9+12x-6x^2=0

6x^2 - 12x + 9 = 0

3(2x^2 - 4x + 3) = 0

2x^2 - 4x + 3 = 0

\Delta = (-4)^{2} - 4 \times 2 \times 3 = 16 - 24 = -8 < 0 so no solutions
