Answer:

The scores within one standard deviation of the mean are: 77, 79, 80, 83, 87, 88

Step-by-step explanation:

The mean of the data is 83 and the standard deviation is 6.5, find scores within 1 standard deviation of the mean:

Between

83 - 6.5 = 76.5

83 + 6.5 = 89.5

So:

The scores within one standard deviation of the mean are: 77, 79, 80, 83, 87, 88

What is the value of -6x3-y2-3xy if x=-2 and y=4
Svetach [21]
<h2>Hello!</h2>

The answer is:

The value of the given expression evaluated with x equals to -2 and y equals to 4, is equal to 56 units.

<h2>Why?</h2>

To solve the problem, we need to evaluate both variables for the given values:

x=-2

and

y=4

So, we are given the expression:

-6x^{3}-y^{2}-3xy

Then, evaluating the given values for both variables, we have:

-6*(-2)^{3}-(4)^{2}-3*(-2)*(4)=(-6*-8)-(16)+24=48-16+24=56

Hence, we have that the answer is:

The value of the given expression evaluated with x equals to -2 and y equals to 4, is equal to 56 units.

Have a nice day!
