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

lord [1]

Answer:

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

$P(X$

To find this probability we use the Z statistic.

$Z = \frac{X- \mu}{\sigma}$

$P(\frac{X- \mu}{\sigma}$

$P(Z$

This is the same as

$P(Z> 2)$

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

$P(X 2) = 0.02275$

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

It happens 2 out of 100 times.

What is the value of f(3) in the function f(x)=5/6x+8

natita [175]

For this case we have a function of the form $y = f (x)$ , where $f (x) = \frac {5} {6} x + 8$

We must find the value of the function when $x = 3$ , that is, we must find f (3). So:

$f (3) = \frac {5} {6} (3) + 8\\f (3) = \frac {15} {6} +8\\f (3) = \frac {5} {2} +8\\f (3) = 2.5 + 8\\f (3) = 10.5$

So $f (3) = 10.5$

Answer:

$f (3) = 10.5$
