The time for this z-score is 3.28.
The formula for z-scores is
z = (X-μ)/σ
Using our information, we have
-1.2 = (X-4.6)/1.1
Multiply both sides by 1.1:
-1.2(1.1) = X - 4.6
-1.32 = X - 4.6
Add 4.6 to both sides:
-1.32 + 4.6 = X - 4.6 + 4.6
3.28 = X
Answer:
125
Step-by-step explanation:
5x5=25
then 25x5=125
Answer:
Plate tectonics explains why Earth's continents are moving; the theory of continental drift did not provide an explanation. Therefore, the theory of plate tectonics is more complete. It has gained widespread acceptance among scientists.
Step-by-step explanation:
Do some research on it.
Answer:
(f + g)(x) = x^2 + 3x - 6
Step-by-step explanation:
Given f(x) = x^2 + x − 2 and g(x) = 2x − 4
Plug in:
(f + g)(x) = x^2 + x − 2 + 2x − 4
(f + g)(x) = x^2 + 3x - 6
yes, I'm pretty shure they do
