Answer:

See below.

Step-by-step explanation:

The standard deviation  =  √  (∑(x - 10)^2 / 8 )  must be approximately = 1 if we take the mean to be 10.

This requires ∑ (x - 10)^2 to be approximately equal to 8.

The following  data set would fit the bill:

8.6  9  9  10 10  11  11  11.5.

The values of (x - 10)^2  could be 1.96, 1, 1, 0,0, 1, 1, 2.25 = 8.21

This would give a mean of about 10 and standard deviation of about 1.

C=-a/b what does a equal
Nutka1998 [239]

Answer:

a = -bc

Step-by-step explanation:

We are given the equation:

c = -a/b

Because multiplication and division are inverse operations, if we move b over to the other side, since it was dividing on the right side, it would be multiplied on the other side (I don't know how to explain that well)

so you can make it look like this:

b*c = -a

Or:

-a = b*c

Then, do isolate a, we will have to divide by -1 on both sides

a = -b*c

To check this, we can plug in numbers

-8 = -16/2

-16 = -8*2

16 = 8 * 2

Let me know if you have any questions
