I’m another normally distributed test score is 80 and the standard deviations is 10. how common are values in the less than 60? show your work

The probability of obtaining a score less than 60 is 2.28%

It happens 2 out of 100 times.

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:

The probability of obtaining a score less than 60 is 2.28%

It happens 2 out of 100 times.

72 is the answer to this problem

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
