Answer:C
Step-by-step explanation:
Looking at number line, the function value always range from positive value from 0 to negative numbers to -1
Answer:
(a+5)^2=25 means a^2+5^2=25, a^2=25-25 then a^2=√0, a=0
Answer:
See explanation below
<u>Step-by-step explanation:</u>
range = 2200 - 300 = 1900
To find standard deviation, we have:
standard deviation = range/4 =
= 475
The range rule of thumb estimate for the standard deviation is 475
Given:
Standard deviation,
= 475
Margin of Error, ME = 100
= 1 - 0.90 = 0.10
Za/2 = Z0.05 = 1.64
Find sample size, n:
n ≥
n ≥
n ≥ 60.68
≈ 61
Minimun sample size,n = 61
Answer: The value of x in this figure is 43
