Y= 250000-8750t

3.5 percent of 250000 is 8750, if that’s the amount decreasing each (t) years, you multiply that number by number of years taken into account.

A score that is three standard deviations above the mean would have a z score of
tia_tia [17]

The value of z-score for a score that is three standard deviations above the mean is 3.

In this question,

A z-score measures exactly how many standard deviations a data point is above or below the mean. It allows us to calculate the probability of a score occurring within our normal distribution and enables us to compare two scores that are from different normal distributions.

Let x be the score

let μ be the mean and

let σ be the standard deviations

Now, x =  μ + 3σ

The formula of z-score is

z_{score} = \frac{x-\mu}{\sigma}

⇒ z_{score} = \frac{\mu + 3\sigma -\mu}{\sigma}

⇒ z_{score} = \frac{ 3\sigma }{\sigma}

⇒ z_{score} = 3

Hence we can conclude that the value of z-score for a score that is three standard deviations above the mean is 3.
