Answer:

9x-18

Step-by-step explanation:

Distribute the Negative Sign:

=12x−14−(3x+9)+−1(−4−1)

=12x+−14+−3x+−9+(−1)(−4)+(−1)(−1)

=12x+−14+−3x+−9+4+1

Combine Like Terms:

=12x+−14+−3x+−9+4+1

=(12x+−3x)+(−14+−9+4+1)

=9x+−18

Answer:

=9x−18

Step-by-step explanation:

In the figure attached, the distribution of data is shown.

From the picture we can see that:

The data has a standard deviation of 0.15 (= 0.5 - 0.35 = 0.65 - 0.5)

The mean of the data is 0.5

A value of 0.7 is more than 1 standard deviation of the mean.

A value of 0.9 is more than 2 standard deviations from the mean (0.8 is 2 standard deviations from the mean)
