The probability that if 5 tires are inspected, exactly 2 have a defect is 0.021
<h3>How to calculate the probability</h3>
The given parameters are:
--- the proportion that contains defect
--- the sample size
-- the selected sample
The probability is then calculated as:
So, we have:
Hence, the probability that if 5 tires are inspected, exactly 2 have a defect is 0.021

Answer:
B
Step-by-step explanation:
The given equations satisfy the given conditions. There are 2 equations and 2 unknowns, so a certain solution can be found.
This can be solved using substitution,
Substituting eqn 2 to eqn 1:
2(2y – 10) + 3y =1240
Simplifying,
y = 180
x = 350
The answer is Identity property of multiplication
Answer:
Step-by-step explanation:
1. Subtract 7 on both sides
2. multiply by 4 on both sides
3. v = 4
Since you are writing this in slope-intercept equation you will want to isolate the y. Therefore move the -8x over making it into -2y=8x+10. Then simply divide by the -2. And your equation will be y=-4x-5.
