1) 5000*90/100=4500
2)5000*0.05=250
3)0.05/(90/100)=5.6%
Answer:
By the Empirical Rule, 99.7% of the students have grade point averages that are between 1.28 and 3.8.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed(bell-shaped) random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 2.54
Standard deviation = 0.42.
Between 1.28 and 3.8?
1.28 = 2.54 - 3*0.42
So 1.28 is 3 standard deviations below the mean
3.8 = 2.54 + 3*0.42
So 3.8 is 3 standard deviations above the mean
By the Empirical Rule, 99.7% of the students have grade point averages that are between 1.28 and 3.8.
Alright, so we are trying to figure out what number 18% of equals 29. First, we should divide 100 by 18 we get 5.55555555555. That means 29*5.5555555555 is the number we are looking for: <em>29*5.5555555555=161.111111</em>
Answer:161.11111111111(repeated infinitely)
