Answer:

^4+2x^3+x+2

Step-by-step explanation:

1. Combine exponents

(+2)(^2x+1)

(x+2)(x^3+1)

2. Distribute

x (x^3+1)+2(x^3+1)

x^4+x+ 2(x^3+1)

3. Solution is x^4 + 2x^3 + x+2

ICE Princess25 [194]

Answer:

Option B is the correct answer.

An association of art museums releases a study reporting that museums with restaurants have a greater number of annual visitors because---

B. There may be a correlation between having a restaurant and having a greater number of annual visitors.

Correlation can be defined as a relationship between two things. Here, the correlation is between the restaurants and the number of visitors. When they don't have restaurant, the number of visitors must have been low.

Consider the function represented by 9x+3y= 12 with x as the independent variable. How can this function be written using

Ivenika [448]

Answer:

f(x)=-3x+4

(can't see some of your choices)

Step-by-step explanation:

We want x to be independent means we want to write it so when we plug in numbers we can just choose what we want to plug in for x but y's value will depend on our choosing of x.

So we need to solve for y.

9x+3y=12

Subtract 9x on both sides

3y=-9x+12

Divide both sides by 3:

y=-3x+4

Replace y with f(x).

f(x)=-3x+4

If the inspection division of a county weights and measures department wants to estimate the mean amount of

Amanda [17]

If inspection department wants to estimate the mean amount with 95% confidence level with standard deviation 0.05 then it needed a sample size of 97.

Given 95% confidence level, standard deviation=0.05.

We know that margin of error is the range of values below and above the sample statistic in a confidence interval.

We assume that the values follow normal distribution. Normal distribution is a probability that is symmetric about the mean showing the data near the mean are more frequent in occurence than data far from mean.

We know that margin of error for a confidence interval is given by:

Me= $z/2* ST/\sqrt{N}$

α=1-0.95=0.05

α/2=0.025

z with α/2=1.96 (using normal distribution table)

Solving for n using formula of margin of error.

$n=(z/2ST/Me)^{2}$

n= $(1.96*0.05)^{2} /(0.01)^{2}$

=96.4

By rounding off we will get 97.

Hence the sample size required will be 97.
