Suppose the time to complete a 200-meter backstroke swim for female competitive swimmers is normally distributed with a mean μ =
Jobisdone [24]

In order to be given a scholarship, a swimmer must complete the 200-meter backstroke in no more than 144 seconds.

<u><em>Explanation</em></u>

Given that the time to complete a 200-meter backstroke swim for female competitive swimmers is normally distributed with a mean μ = 141 seconds and a standard deviation σ = 7 seconds

The fastest 6% of female swimmers in the nation are offered college scholarships. So, the probability will be 0.06

According to the normal distribution table, the z-score for probability of 0.06 is   0.5239

Now using z-score formula z= (x- μ)/σ , we will get...

0.5239= \frac{x-141}{7}\\ \\ x-141= 3.6673\\ \\ x= 3.6673+141 \\ \\ x= 144.6673

That means, x < 144 <em>(in whole number)</em>

So, in order to be given a scholarship, a swimmer must complete the 200-meter backstroke in no more than 144 seconds.

Determine if each root is a rational or irrational number. Explain your reasoning. a.√36 b.√78
zmey [24]

Answer:

a) rational

b) irrational

Step-by-step explanation:

a) 36 = 6²

So sqrt(36) = 6

b) 72 = 2 × 36

sqrt(72) = sqrt(2) × sqrt(36)

Since 2 is not a perfect square, sqrt(72) is irrational
