Answer:

\frac{36}{25x^{20} }

Step-by-step explanation:

In order to simplify this function, we have to divide by the maximum common divisor:

\frac{72x^{16} }{50x^{36} }\\ 72/2=36\\50/2=25\\\frac{36}{25} \\(x^{16} )(x^{-36})=x^{-20}=\frac{1}{x^{20} } \\\frac{36}{25x^{20} }

By doing this you can simplify the function into the simplified form.

Quintina decided to increase the deduction percentage of her federal income tax rate from 14% to 16%. Quintina’s gross pay per m
rodikova [14]

Answer:

The monthly net pay is $1555 .

Step-by-step explanation:

As given

Quintina decided to increase the deduction percentage of her federal income tax rate from 14% to 16%.

Quintina’s gross pay per month is $2,100.

16% is written in the decimal form .

= \frac{16}{100}

= 0.16

Federal income tax = 0.16 × Gross pay

                                = 0.16 × 2100

                                = 336

Monthly net pay = Gross  pay - Federal income tax  -  State Income Tax - Social Security - Medicare

                           = 2100 - 336 - 89 - 85 - 35

                          = 2100 - 545

                         = $1555

Therefore the monthly net pay is $1555 .

Franchise Business Review stated over 50% of all food franchises earn a profit of less than $50,000 a year. In a sample of 130 c
nydimaria [60]

Answer:

We need a sample size of 564.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

For this problem, we have that:

\pi = \frac{81}{130} = 0.6231

The margin of error is:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

95% confidence level

So \alpha = 0.05, z is the value of Z that has a pvalue of 1 - \frac{0.05}{2} = 0.975, so Z = 1.96.

Based upon a 95% confidence interval with a desired margin of error of .04, determine a sample size for restaurants that earn less than $50,000 last year.

We need a sample size of n

n is found when M = 0.04

So

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

0.04 = 1.96\sqrt{\frac{0.6231*0.3769}{n}}

0.04\sqrt{n} = 1.96\sqrt{0.6231*0.3769}

\sqrt{n} = \frac{1.96\sqrt{0.6231*0.3769}}{0.04}

(\sqrt{n})^{2} = (\frac{1.96\sqrt{0.6231*0.3769}}{0.04})^{2}

n = 563.8

Rounding up

We need a sample size of 564.

2x+ 3 / 5= y<br> rearrange to make x the subject
Elza [17]

Answer:

<h3>(5y-3)/2</h3>

Step-by-step explanation:

Given the equation 2x+ 3 / 5= y

Cross multiply

2x+3 = 5 * y

2x+3 = 5y

Subtract 3 from both sides

2x+3-3 = 5y - 3

2x = 5y-3

Divide both sides by 2

2x/2 = (5y-3)/2

x = (5y-3)/2

Hence the value of x is (5y-3)/2
