#2) The following discrete probability distribution was created from data gathered by an online shopping site that sells gluten free cereal. # of items purchased, x Probability, P(x) 0 0.205 1 0.315 2 0.448 3 0.032 A) Show your work to find the Mean of the distribution. B) Show your work to find the Standard Deviation for the distribution. C) Thinking in terms of an online shopping website, give an example of something that could be discrete variable and something that could be a continuous variable. Justify your answer, convince me that you understand the difference between a continuous variable and a discrete variable. #3) Thirty-nine percent of U. S adults think that the government should help fight childhood obesity. You randomly select six U. S. adults. Find the probability that the number of U. S. adults who think that the government should help fight childhood obesity is: A) Exactly two. B) At least four. C) Less than three.

what?

step-by-step explanation:

what do you need with. i love quadrants. can you tell me ?

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

ok then what happened.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
