Answer:
The mean is 15.93 ounces and the standard deviation is 0.29 ounces.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
7% of the bottles containing this soft drink there are less than 15.5 ounces
This means that when X = 15.5, Z has a pvalue of 0.07. So when X = 15.5, Z = -1.475.
10% of them there are more than 16.3 ounces.
This means that when X = 16.3, Z has a pvalue of 1-0.1 = 0.9. So when X = 16.3, Z = 1.28.
From above
So
The mean is
The mean is 15.93 ounces and the standard deviation is 0.29 ounces.
7/18! This is because if you double both the top and bottom of 8/9 you get 16/18. Half of 18 is 9. So if we use half a yard, 9/18, and we subtract it from 16/18, we get 7/18!
Answer:
yes but no
Step-by-step explanation:
um well that is a lot by not if there is a bunch of people doing it.
g(x) = -3x + 5
g(-2) = -3(-2) + 5
g(-2) = 6 + 5
g(-2) = 11
(x, y) = (-2, 11)
g(x) = -3x + 5
g(0) = -3(0) + 5
g(0) = 0 + 5
g(0) = 5
(x, y) = (0, 5)
g(x) = -3x + 5
g(3) = -3(3) + 5
g(3) = -9 + 5
g(3) = -4
(x, y) = (3, -4)
