The insurance period must be chosen so that the probability of a microchip failure within that period is 4%. Reference to a standard normal distribution table shows that the z-score for a cumulative probability of 4% is -1.75.
Let the insurance period be X months:
-1.75 = (X - 93)/3.8
-6.65 = X - 93
X = 83.35 months.
The answer is 83.35 months.
Answer:
24
Step-by-step explanation:
The LCM or least common multiple of these numbers is 24
To get 24, you list all the multiple of these numbers until they all share at least one
So
2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, <u>24</u>
6, 12, 18, <u>24</u>
8, 16, <u>24</u>
They all share 24 so this is the LCM
