Answer:
<em>The probability of obtaining a score less than 60 is 2.28%
</em>
<em>It happens 2 out of 100 times.</em>
Step-by-step explanation:
If the mean μ = 80 and the standard deviation σ = 10, then we need to find the probability that an X value is less than 60.
Then we find

To find this probability we use the Z statistic.



This is the same as

We look for this value in the table for the normal distribution of right queue and we have:

<em>The probability of obtaining a score less than 60 is 2.28%
</em>
<em>It happens 2 out of 100 times.</em>

Answer:
<h2>x = 16.55</h2>
Step-by-step explanation:
1.06(12.95 + x) = 31.27
<u>Multiply the terms in the bracket</u>
That's
13.727 + 1.06x = 31.27
<u>Subtract 13.727 from both sides</u>
That's
13.727 - 13.727 + 1.06x = 31.27 - 13.727
1.06x = 17.543
<u>Divide both sides by 1.06</u>
That's

We have the final answer as
<h3>x = 16.55</h3>
