Agiven by no real distribution has a mean of 153.1 and a standard deviation of 18.2 would a value of 187 be considered usual or unusual? why?

➷ (18.2 x 2) + 153.1 = 189.5 (this is considered the highest value)

153.1 - (18.2 x 2) = 116.7 (this is considered the lowest value

An unusual value would be more than 2 standard deviations away from the mean in a positive or negative direction.

In this case, the value is less than the highest value.

The value of 187 would be considered usual as it is less than 2 standard deviations away from the mean.

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
