Answer: Estimated the standard deviation α = 5.35
Step-by-step explanation:
According to Empirical rule, the largest value is approximately:
ц + 3α
And the smallest value is approximately:
ц + 3α
Based on the given figures in the question, we can say
ц + 3α = 140.6
ц - 3α = 108.5
Now subtracting these two; we have
ц + 3α - ( ц - 3α ) = 140.6 - 108.5
ц + 3α - ц + 3α = 32.1
6α = 32.1
α = 32.1 / 6
α = 5.35
Estimated the standard deviation α = 5.35
Answer:
x is less than or equal to -23
Step-by-step explanation:
-x is greater than or equal fo 23 divide negative on both sides
x is less than or equal to -23

Answer:
b
Step-by-step explanation:
Step-by-step explanation:
f(x) = x² - 2x - 3
g(x) = 4x²
f(g(x)) = f(4x²)
f(4x²) = (4x²)² - 2(4x²) - 3
= 16x⁴ - 8x² - 3
Arrange from smallest to largest
-25, -12/4, 1/5, 18/5, 10
chose the middle number
1/5
