The discount is 50-14 = $36
% discount = (36/50)*100 = 72%
Answer:
So about 95 percent of the observations lie between 480 and 520.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviations of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
The mean is 500 and the standard deviation is 10.
About 95 percent of the observations lie between what two values?
From the Empirical Rule, this is from 500 - 2*10 = 480 to 500 + 2*10 = 520.
So about 95 percent of the observations lie between 480 and 520.
Answer:
8×
Step-by-step explanation:
you just add 7×+1 and the answer will be 8×
165 divided by 11 equals 15
3 square root is called cube root btw:
cube root of -27/64 is the same as (cube root of -27)/(cube root of 64)
cube root of -27 is -3
cube root of 64 is 4
the anser is -3/4
