Answer:
2.4
Step-by-step explanation:
132/55=2.4
MA=output force/input force.
X=-3X=2 —> move the variable to the left handed side and change its sign
-2x=2 —> collect like terms
Divide both sides of the equation by -2 and your answer is x=-1
Given:
n = 150, sample size
Denote the sample proportion by q (normally written as
).
That is,
q = 60/150 = 0.4, sample proportion.
At the 96% confidence level, the z* multiplier is about 2.082, and the confidence interval for the population proportion is
That is,
0.4 +/- 2.082* √[(0.4*0.6)/150]
= 0.4 +/- 0.0833
= (0.3167, 0.4833)
= (31.7%, 48.3%)
Answer: The 96% confidence interval is about (32% to 48%)
Live Fund receive it they sold half thier holding in Marks Brothers.
