First find LCM (least common denominator) which is 12
so now u have 3/4 x 3= 9/12 and 2/3 x 4 = 8/12
now add 9/12 + 8/12 to get answer
try the rest on your own hope dis helped <span>✌️</span>

Answer:
y= 2x-1/2 is x=.5 y + .25

Answer:
b>5
=greater than or equal too
Step-by-step explanation:
divide -35 by -5, and since you are dividing by a negative, the sign flips
Answer:
0.0177 = 1.77% probability that the first defect is caused by the seventh component tested.
The expected number of components tested before a defective component is found is 50, with a variance of 0.0208.
Step-by-step explanation:
Assume that the probability of a defective computer component is 0.02. Components are randomly selected. Find the probability that the first defect is caused by the seventh component tested.
First six not defective, each with 0.98 probability.
7th defective, with 0.02 probability. So

0.0177 = 1.77% probability that the first defect is caused by the seventh component tested.
Find the expected number and variance of the number of components tested before a defective component is found.
Inverse binomial distribution, with 
Expected number before 1 defective(n = 1). So

Variance is:

The expected number of components tested before a defective component is found is 50, with a variance of 0.0208.
