The answer should be D. 165.85+20.5x. This is because 165.85 is what he first deposited. 20.5 is what he deposits each week . x is the amount of weeks he’s deposited. whatever amount of weeks , you would multiply it with 20.5 and then add that amount to the amount he already had which was 165.85

Answer: 0.8413

Step-by-step explanation:

Given : Henry has collected data to find that the typing speeds for the students in a typing class has a normal distribution.

Mean : $\mu=47$

Standard deviation : $\sigma= 4$

Let x be the random variable that represents the typing speeds for the students.

The z-score :-

$z=\dfrac{x-\mu}{\sigma}$

For x= 51

$z=\dfrac{51-47}{4}=1$

Using the standard normal distribution table ,the probability that a randomly selected student has a typing speed of less than 51 words per minute :-

$P(x$
