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:
Step-by-step explanation:
let ∠GEF=x
then ∠GFE=90-x

((-3)^2)^3
The rule for raising and exponent to another exponent is:
(a^b)^c=a^(b*c) so:
((-3)^2)^3
(-3)^(2*3)
(-3)^6
