Aset of data with a mean of 40 and a standard deviation of 5.1 is normally distributed. find the value that is −2 standard deviations from the mean. 25.7 34.9 45.1 29.8

Answer : 29.8

A set of data with a mean of 40 and a standard deviation of 5.1 is normally distributed.

Mean = 40

standard deviation = 5.1

Find the value that is −2 standard deviations from the mean.

standard deviation = 5.1

-2 standard deviation =

The value that is −2 standard deviations from the mean = 40 - 10.2

= 29.8

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

it would rotate about 180 degrees.
