William has a lemonade stand today he made $17.55 and lemonade sales and one-third that amount in cookie sales how much money di
IgorC [24]

Answer:

Well to find 1/3 of something you have to multiply it by 1/3.

1/3 in decimal form is .33 repeating.

17.55 * .33 = 5.79

17.55 + 5.79 = $23.34

$23.34 is the total profit.

(10v^4 + 30v^3 + 2v^2) / 10v
Zina [86]

Given expression is

\frac{10v^4+30v^3+2v^2}{10v}

Now we need to simplify this expression. We can begin by factoring numerator and denominator if possible.

= \frac{2v^2(5v^2+15v+1)}{10v}

divide numerator and denominator both by 2v

= \frac{v(5v^2+15v+1)}{5}

= \frac{5v^3+15v^2+1v}{5}

Hence final answer is \frac{5v^3+15v^2+1v}{5}

Or you can also keep factored form

\frac{v(5v^2+15v+1)}{5}

Suppose a call center receives 4000 calls on average during their Friday evening shift. Next Friday several people have put in f
luda_lava [24]

Answer:

The probability that the center will have enough employees to handle this call volume is 0.2764

Step-by-step explanation:

Probability is defined as the ratio of favorable outcomes to the total number of outcomes.

Here the total mean expected number of outcomes=u = 4000

The favorable  expected outcomes are = x= 22* 178= 3916

The  standard deviation= σ= 5

The random variable X =178 has normal distribution with mean 4000/22 and standard deviation 5

So z= x-u/σ

Z= (3916-4000)/22/5

z= -0.764

From the table of areas under normal curve

P (  x= 3916)=  P( -0.764 ≤ Z≤ 0)

P (  x= 3916)=  0.2764

The probability that the center will have enough employees to handle this call volume is 0.2764
