Help please I get y=mx+b but I'm not sure how to do this

Fofino [41]

(3,4) (9,7)

to find the slope

m = (y2-y1)/(x2-x1)

= (7-4)/(9-3)

3/6

1/2

The slope is 1/2

point slope form

y-y1 = m(x-x1)

y-4 = 1/2(x-3)

distribute

y-4 = 1/2x -3/2

add 4 to each side

y = 1/2 x -3/2 + 4

y = 1/2 x -3/2 + 8/2

y = 1/2 x + 5/2

this is in slope intercept form

A quiz consists of 20 multiple-choice questions, each with 5 possible answers. for someone who makes random guesses for all of t

blondinia [14]

N = 20, the number of questions
p = 1/5 = 0.2, the probability of making a correct guess
q = 1 - p = 0.8, the probability of making an incorrect guess.
Expected success = 60% or 6 of 10.

From the binomial distribution,
P(6 of 10) = ₁₀C₆ p⁶q⁴
= 210*0.2⁶*0.8⁴ = 0.0055

So. At oaknoll school 90 out of 270 students own computers. What percent of students at oaknoll school do not own computers? Rou

Arada [10]

Answer: There have 66.66..7% of Student own computer(s).

Step-by-step explanation:

What I did is make the whole school (270) be 100%, then I subtract from Whole school to own computer and the answer will be not own computer: 270 - 90 = 180, so there has 180 students who do not own computer, but we want to find the percentage. So we multiply 180 and 100, we will get 18,000! Then divide it to 270 and we will get 66.66..7, write it on top of 100, so it would be 66.66../100 which mean 66.66..% or 66.66..7%
