What happens to the mean of the data set {10, 2, 8, 9, 5, 2, 6} if the number 12 is added to the data set?

Step-by-step explanation:

10+2+8+9+2+6+12/7

=49/7

= 7

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
