Two angles are complementary angles if they have a sum of 90 degrees. We could write the expression as below.
angle 1 + angle 2 = 90
7x + 2 + 3x - 2 = 90
solve for x by adding like terms
7x + 3x + 2 - 2 = 90
10x = 90
x = 90/10
x = 9
The value of x is 9
Considering that the mean of the normal distribution is the same as the median, the median is of 88%.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
For the normal distribution, the median is the same of the mean, that is, the median is of 88%.

Answer:
Future Value= $530.45
Step-by-step explanation:
Giving the following information:
Initial investment (PV) = $500
Number of periods (n) = 2 years
Interest rate (i)= 3% = 0.03
<u>To calculate the future value (FV), we need to use the following formula:</u>
FV= PV*(1+i)^n
FV= 500*(1.03^2)
Future Value= $530.45
Csc theta=-2 then theta equals csc^-1(-2) then theta would equal 5pi/6, 7pi/6
