What is the equation, in point-slope form, for a line that goes through (8, −4) and has a slope of −5/6 ?
horrorfan [7]

Point-slope form, y-y1 = m(x-x1)

(y-(-4)) = -5/6 (x-8)

y+4 = -5x/6+20/3

y = -5x/6+20/3 - 4

y = -5x/6 + 8/3

"5. Multiple-choice questions each have five possible answers (a,b,c,d,e), one of which is correct. Assume that you guess the an
Nina [5.8K]

Answer:

A) P(WWC) = 0.128

B) P(WCC) = 0.032

P(CWC) = 0.032

P(CCW) = 0.032

C) probability of getting 2 correct answers when 3 guesses are made is i.e P (1 wrong and 2 correct) = 0.064

Step-by-step explanation:

A) Using the multiplication rule, we have; P(A and B) = P(A) x P(B)

Probability of a wrong answer = 4/5 = 0.8

Probability of a correct answer = 1/5 =0.2

Thus; P(WWC) = 0.8 x 0.8 x 0.2 = 0.128

B) Beginning with one wrong and two correct answers, a complete list of all possibilities is;

P(WCC), P(CWC), P(CCW)

Hence the complete list is;

(0.8 x 0.2 x 0.2); (0.2 x 0.8 x 0.2); (0.2 x 0.2 x 0.8)

So we have;

P(WCC) = 0.032

P(CWC) = 0.032

P(CCW) = 0.032

C) Based on the results above, the probability of getting 2 correct answers when 3 guesses are made is i.e P(1 wrong and 2 correct) = 2 x 0.032 = 0.064
