A because inverse is the opposite order so instead of -3/1 or 5/1 it becomes 1/-3 and 1/5
Answer:
18/6=324/6=418/24=3/4
Step-by-step explanation:
if you multiply 2 times something you can’t get anything 11. the closest denominator is 5 and 5x2=10 so you have one left to get 11 so the answer is =5with 1$ still left. maria can buy 5 fish but she will have 1$ left over.
Hope this helps.
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.
