Step-by-step explanation:
Solve for a
k + a = v + w
a = v + w - k
Solution → { a = v + w - k }
Question A is asking: Considering the distribution shape (i.e skewed left, right, or symmetrical), what measure of center would be used? Explain why that measure of center would be used.
Question B is asking: What measure of variability (or change, i.e range, interquartile range, or standard deviation) would be used for this graph? Explain why this measure would be used.
Answer:
14x-11
Step-by-step explanation:
f(x) = 2x − 5
g(x) = 7x − 3
(f(g(x))=
Substitute g(x) into f(x) for every x
f(g(x) = 2 (g(x) -5
=2 (7x-3) -5
Distribute
=14x-6 -5
=14x-11
Answer: 1/15
Step-by-step explanation:
The number of striped socks is 2 while the number of total socks are 6. If he chooses a striped socks at first, that will be 2/6.
If he chooses it the second time, the probability will be 1/5 since there'll be 5 socks left and 1 striped.
The probability that Derek selected a striped sock both times will be:
= 2/6 × 1/5.
= 2/30
= 1/15
