Quiz 4: Solving Inequalities

san4es73 [151]

Answer:

$15x+60\leq 100$

Step-by-step explanation:

Let

x -----> the number of hours that the painter works

we know that

The inequality that represented this situation is equal to

$15x+60\leq 100$

solve for x

Subtract 60 both sides

$15x\leq 100-60$

$15x\leq 40$

Divide by 15 both sides

$x\leq 40/15$

$x\leq 2.67\ hours$

The maximum number of hours is 2

A case of wine has 12 bottles, three of which contain spoiled wine. A sample of four bottles is randomly selected from the case.

asambeis [7]

Answer: (4Cx) × (0.25^x) × (0.75^4-x), mean =1, variance = 0.75

Step-by-step explanation:

Total bottle of wine = 12

Number of spoilt wine = 3

p(spoilt wine) = 3/12 = 1/4 = 0.25, q = 1 - 0.25 = 0.75.

n = number of bottles selected randomly = 4.

Since n = 4, then the experiment is of a binomial.

The probability mass function for a binomial distribution is given as

p(x=r) = nCr × p^r × q^n-r

The distribution for x is given below as

P(X=x) = (4Cx) × (0.25^x) × (0.75^4-x)

The mean for a binomial probability distribution is given as

Mean = np = 4×0.25 = 1

Variance = npq = 4×0.25×0.75 = 0.75

2to the power of n • 2 divided by 2 to the power of 5 = 2to the power of 2 what is N

mestny [16]

If I understand correctly, what you're saying is 2^2n ÷ 2^5 = 2^4

the easiest way to do this is to get rid of the fraction by multiplying both sides by 2^5 and getting
2^2n = 2^9 (Because when you multiply exponents with the same base you add the exponents)
Because the bases are the same you can set the exponents equal to each other getting
2n=9
n=9/2 or 4.5
