The mean of three numbers is 8 two of the numbers are 6 and 11 work out the third number

Andreas93 [3]

Answer:

7

Step-by-step explanation:

To find the number, first multiply 8 by 3, since that is how you find the mean.

8 x 3 = 24 (total)

x + 6 + 11 = 24

x = 24 - 6 - 11

x = 7

Inverse:

7 + 6 + 11 = 24

Mean = 24/3 = 8

Hope this helps!

What is the slope of a line that is perpendicular to the line v=-1/3x-6

bija089 [108]

If you are trying to find the slope of a line that is perpendicular to another line, you would need to change the sign and change it to the fraction's reciprocal.

m = $-\frac{1}{3}$

Change the sign of the slope:

$\frac{1}{3}$

Finally, make the reciprocal of the original slope (switching the numerator and denominator):

$\frac{3}{1}$

Simplify:

3

Final answer:

$m=3$
