Multiply both sides by -3 to get rid of the negative and the fraction.
X - 3 = 21
Move the constants over to isolate the variable
X = 24
Answer:
68% of an investment earning a return between 6 percent and 24 percent.
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 deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 15
Standard deviation = 9
How likely is it to earn a return between 6 percent and 24 percent?
6 = 15 - 1*9
6 is one standard deviation below the mean
24 = 15 + 1*9
24 is one standard deviation above the mean
By the empirical rule, there is a 68% of an investment earning a return between 6 percent and 24 percent.
So you are given the amount he sold which is $7300, and you are given his commission rate so all you have to do is this
7300 x 0.12 = 876
Therefore, his amount of commission is 876 dollars
Answer:
x^9/8
Step-by-step explanation:
The exponent property that you can use here is that when multiplying the two exponents, you add their exponents
Thus, (x^7/8) (x^1/4) = x^(7/8+1/4)=x^9/8
