Answer: h= 7/10
Step-by-step explanation:
9(4h - 6 ) = 2(-13 - 2h) Distribute on both sides
9(4h) + 9(-6) = 2(-13) + 2(-2h)
36h - 54 = -26 - 4h Add 4h to both sides
+4h +4h
40h - 54 = -26 Add 54 to both sides
+54 +54
40h = 28 Divide both sides by 40
h = 7/10

Answer:
P(X>17) = 0.979
Step-by-step explanation:
Probability that a camera is defective, p = 3% = 3/100 = 0.03
20 cameras were randomly selected.i.e sample size, n = 20
Probability that a camera is working, q = 1 - p = 1 - 0.03 = 0.97
Probability that more than 17 cameras are working P ( X > 17)
This is a binomial distribution P(X = r) 

P(X>17) = P(X=18) + P(X=19) + P(X=20)
P(X=18) = 
P(X=18) = 
P(X=18) = 0.0988
P(X=19) = 
P(X=19) = 
P(X=19) = 0.3364
P(X=20) = 
P(X=20) = 
P(X=20) = 0.5438
P(X>17) = 0.0988 + 0.3364 + 0.5438
P(X>17) = 0.979
The probability that there are more than 17 working cameras should be 0.979 for the company to accept the whole batch
