Answer:

A) 57%

B) 16%

C) 53%

D) 57%

Step-by-step explanation:

Let R1 be students that attend class regularly

R2 be students that don't attend class regularly

A be students that receives A's in class

A) From the question A/R1 =57%

P(A/R1) = 0.57

B) From the question students that receive As that does not attend lectures regularly =16%

C) P(R2) = 1 -0.57 = 0.43

P(A) = P(A/R1) × P(R1) + P(A/R2)×P(R2)

P(A) = (0.57× 0.81) + (0.16×0

43)

P(A) = 0.46 + 0.0688= 0.53

The overall percentage that recieved A's = 53%

D) 57% recieved A's given that they attend class regularly.

Solve for . 5w-26=-4(w-7) Simplify your answer as much as possible. PLZ HELP
NikAS [45]

Answer:

w = 6

Step-by-step explanation:

5w-26 = - 4 (w - 7)   multiply -4 through

5w - 26 = - 4w + 28  add 4w to each side to cancel it out on the right

5w + 4w - 26 = 28  

9w - 26 = 28  Now add 26 to each side

9w - 26 + 26 = 28 + 26

9w = 54   Now divide each side by 9

(9w)/9 = 54/9

w = 6
