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.
(Observed data - Accepted standard) divided by the accepted standard. Then all of that is multiplied by 100.
( ( O - A ) / A) * 100
Answer and Step-by-step explanation:
Solve for m.
<u>First, distribute the 5.</u>
5 + 20m - 2m = -13
<u>Combine like terms.</u>
5 + 18m = -13
<u>Subtract 5 from both sides of the equation.</u>
18m = -18
<u>Divide by 18 to both sides of the equation.</u>
<u>m = -1 <- This is the answer.</u>

Answer:
9. 7/2
10. -6
Step-by-step explanation:
1. Negative
Explanation: A negative minus a positive will be a negative
2. Negative
Explanation: If you use your order of operations a negative multiplied by a negative will be positive but since BxB would be greater than A it would be negative for example 2-8 would equal -6
