Order the steps to solve the equation
log(x2 - 15) = log(2x) form 1 to 5.
x² - 2x - 1550
Potential solutions are -3 and 5
x2 - 15 = 2x
x - 5 = 0 or x + 3 = 0
(X - 5)(x + 3) = 0
DONE

don't know what that says sorry i can't you

step-by-step explanation:

idk what it says

i believe that the answer is

b. y-1=-2(x-4)

hope this !

irst, find the z score of a score of 80. this is given by the formula z = (x-u)/o, where x is the score, u is the mean, and o is the standard deviation. this gives

z = (80-78)/12 = 1/6 = .1667

now, find what percentile a z score of 1/6 correlates to in the normal distribution.

a z score of 1/6 = .1667 is equivalent to the 56.36th percentile of the distribution. so the probability a score is over this is 1-.5636 = .4364

the mean of a sample mean is equal to the original mean. however, the standard deviation of a sample mean is equal to the original standard deviation divided by the square root of n (sample size). so the new standard deviation is 12/sqrt(16) = 3.

the new z score is 80-78/3 = 2/3 = .667. this is equivalent to the 74.86th percentile. so the probability that the mean will be greater than this score is 1-.7486 = .2514.
