Answer:

m ≥- 28 / 5

Step-by-step explanation:

–5(m + 1) ≤ 23

Distribute

-5m -5 ≤ 23

Add 5 to each side

-5m -5+5 ≤ 23+5

-5m ≤ 28

Divide each side by -5, remembering to flip the inequality

-5m/-5 ≥ 28 / -5

m ≥- 28 / 5

= 57.36 lbs. (rounded off to 2 decimal places) 

2) sin60 = .866 
F = 18(.866) 
= 15.59 lbs. (rounded off to 2 decimal places)

Suppose that you bet $5 on each of a sequence of 50 independent fair games. Use the central limit theorem to approximate the pro

amm1812

Answer:

chances chances of happening = 0.0119

Step-by-step explanation:

given data

bet = $5

independent fair games = 50

solution

we will think game as the normal distribution

so here mean is will be

mean = $\frac{50}{2}$

mean = 25

and standard deviation will be

standard deviation = $\sqrt{50*0.5*0.5}$

standard deviation = 3.536

we have to lose 33 out of 50 time for lose more than $75

so as chance of doing things z score is

z score = $\frac{33-25}{3.536}$

z score = 2.26

so from z table

chances chances of this happening = 0.0119
