Answer:
11/20
Step-by-step explanation:
22/50 is equivalent because if you multiply 50 by 2 to get 100, then multiply 22 by 2, you get 44 out of 100 (44). For 11/20 if you multiply 20 by 5 to get 100, then multiply 11 by 5, you get 55 out of 100 (55). Do the same thing for all the other ones. I hope this helps! Please mark me brainliest thanks!
3a + b = 54
Substitute b for 9
3a + 9 = 54
Subtract 9 to both sides
3a = 45
Divide 3 to both sides
a = 15

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.
Not clear.
