Answer:
B. 52
Step-by-step explanation:
T and S are the same
2x + 2 + 2x + 2 + 3x + 1 = 180
2x + 2x + 3x + 2 + 2 + 1 = 180
7x + 5 = 180
7x = 180 - 5
7x = 175
7x/7 = 175/7
x = 25
2x + 2
2(25) + 2
50 + 2
53
Pretty sure it’s obtuse !
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.
Answer:
<em><u>=15a−8</u></em>
Step-by-step explanation:
Let's simplify step-by-step.
4(2a−1)−4+7a
Distribute:
=(4)(2a)+(4)(−1)+−4+7a
=8a+−4+−4+7a
Combine Like Terms:
=8a+−4+−4+7a
=(8a+7a)+(−4+−4)
=15a+−8
Answer:
=15a−8
