Answer:
0.0015 is he probability that a randomly selected student has a body weight of greater than 169 pounds.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 142 pounds
Standard Deviation, σ = 9 pounds
We are given that the distribution of body weights is a bell shaped distribution that is a normal distribution.
Empirical Rule:
- The empirical rule states that for a normal distribution 68% falls within the first standard deviation from the mean, 95% within the first two standard deviations from the mean and 99.7% within three standard deviations of the mean.
P( body weight of greater than 169 pounds)
According to empirical rule, 99.7% within three standard deviations of the mean.
Thus, we can write:
P( body weight of greater than 169 pounds)
0.0015 is he probability that a randomly selected student has a body weight of greater than 169 pounds.
Answer:
4.3
Step-by-step explanation:
look at the picture .......
The slope is -2/7. I hope that helps
Well if 1 is 20 square inches then times 20 X 30 which equals 600. So the area is 600 square inches.
Answer:
m = 1, y = 1x + 10
Step-by-step explanation:
The equation of a line is y = mx + c where m is the slope and c is the y-intercept. I will be calculating the slope using the points (7, 2) and (0, 10)
m =
=
=
= 1
Based on the graph, the y-intercept is 10. Thus, the equation of the line is 1x + 10.
