The mean is != 15.2 and the standard deviation is σ = 0.9. Find the probability that X is between 14.3 and 16.1.

95%

Step-by-step explanation:

Assuming the distribution is normally distributed with a mean of

and standard deviation

We want to find the probability that X is between 14.3 and 16.1

We find z-scores to get:

We simplify to get:

According to the empirical rule, approximately 95% of the distribution falls within one standard deviation of the mean.

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).
