Answer:Z=1
Step-by-step explanation: if it is 11z+5, then... minus 9z on each side to get 2z+5=7. Minus 5 on each side to get 2z=2. Divide bboth sides by two to get 1z=1.
Answer:
c. The expected values of R and S will be equal, and the variability of R will be greater than the variability of S.
Step-by-step explanation:
This is Central Limit Theorem concept in which independent variables are added and form a normal distribution. The random sample of n sample size is selected which calculates normally distributed mean and variance. The expected value of samples distributor will be higher than the sample distribution.
You want to make the fractions have the same denominator.
2/3 = 8/12
1/4 = 3/12
now subtract the numerator and keep the denominator the same...
8/12 - 3/12 = 5/12
5 1/2 is the answer
Answer:
Yes.
Step-by-step explanation:
The answer is 7,388,854,191,165
7,388,475,694,872+378,496,293=7,388,854,191,165
