A triangle has vertices A (1, 1), B (2, 4), and C (4, 2). Line p is parallel to side AB and contains point C. Part I: Find the slope of AB. Show your work
Part II: Use the slope from Part I and point C to write an equation for line p in the slope-intercept form.
Show your work
Part III: Graph and line p on the grid to show AB and line p are parallel

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

could u provide us some answer choices or hmm idk maybe a table for us to anser with ? ?

the answer is c 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.
