Hello!
The mean is 12
The data has a standard deviation of 4
Look and see how far away 18 is from 12 using 4
12 + 4 = 16
16 is one deviation
16 + 4 = 20
20 is two deviation
18 is right in the middle
The answer is C. 1.5 deviations
Hope this helps!
Answer:
x4
Step-by-step explanation:
going down on the x axis
Answer:
steps below
Step-by-step explanation:
a) f(x) = (x+2)² - 9
b) y = (x-h)² + k , (h,k) is vertex vertex (-2 , -9)
x intercept: (x+2)² - 9 = 0
x+2 = ± 3
<u>x = 1 or x = -5</u>
y intercept: <u>y = -5</u>
c) attached
d) y ≥ -9 [-9,∞)
