Answer 2
Answer:

Answer:

sqrt(2)

Step-by-step explanation:

1. Find the mean.

Mean=1+2+3+4+5=15/5=3

2. Subtract each number by the mean and square the value.

1-3=-2^2=4

2-3=-1^2=1

3-3=0^2=0

4-3=1^2=1

5-3=2^2=4

3. Add the values in step 2 then divide by amount of numbers.

4+1+0+1+4=10/5=2

4.Square the value in step 3 and that is the answer.

sqrt(2)

Y varies directly as x. if x =5 when y=12. find x when y=30

Answers

x = 5 ... y = 12
x = ? ... y = 30

If you would like to know the value of x when y = 30, you can calculate this using the following steps:

5 * 30 = x * 12
x * 12 =150    /12
x = 150 / 12
x = 12.5

The result is 12.5.
