Answer:
60 months
Step-by-step explanation:
20 000 = 5000 + 250 m
20 000 - 5000 = 250 m
(15 000) / 250 = m = 60 months
4(2x-4)^2 - 3
4(4x^2 - 2(4)(2x) + 16) - 3
4(4x^2 -16x + 16) - 3
16x^2 - 32x + 32 - 3
16x^2 - 32x + 29
Answer:
d. 0.3446
Step-by-step explanation:
We need to calculate the z-score for the given weekly income.
We calculate the z-score of $1000 using the formula

From the question, the standard deviation is
dollars.
The average weekly income is
dollars.
Let us substitute these values into the formula to obtain:



We now read from the standard normal distribution table the area that corresponds to a z-score of -0.4.
From the standard normal distribution table,
.
We round to 4 decimal places to obtain:
.
Therefore the probability that a trainee earns less than $1,000 a week is
.
The correct choice is D.
