Answer:

0.9974 = 99.74% probability of selecting a sample of 65 one-bedroom apartments and finding the mean to be at least $2,260 per month.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

The rent for a one-bedroom apartment in Southern California follows the normal distribution with a mean of $2,350 per month and a standard deviation of $260 per month.

This means that [tex]\mu = 2350, \sigma = 260[/tex]

Sample of 65 one-bedroom apartments

65>30, which means that the sampling distribution of the sample means will be approximately normal. Also, [tex]n = 65, s = \frac{260}{\sqrt{65}} = 32.249[/tex]

What is the probability of selecting a sample of 65 one-bedroom apartments and finding the mean to be at least $2,260 per month?

This is 1 subtracted by the pvalue of Z when X = 2260.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{2260 - 2350}{32.249}[/tex]

[tex]Z = -2.79[/tex]

[tex]Z = -2.79[/tex] has a pvalue of 0.0026

1 - 0.0026 = 0.9974

0.9974 = 99.74% probability of selecting a sample of 65 one-bedroom apartments and finding the mean to be at least $2,260 per month.

Answer:

One pound can be written as 1.0 pounds, and moving the decimal place one place to the left gives you 0.10 pound, which is equal to one tenth of a pound. Convert 16 oz. to one sixteenth of an ounce by moving the decimal one place to the left.

Answer:

C. 24 units3 =8 units3 ×324 units3 =8 units3 ×3

Answer:

[tex]4x^{6}2y^{-2}[/tex]

Step-by-step explanation:

We can use a property I like to call SEi-F. (Subtract Exponents in a Fraction)

But first, there is an exponent outside of the parentheses in both places. We can use the Power of Parentheses to simplify and then use the SEi-F.

We will start with the x in the numerator.

3*4 = 12

Now for the y in the numerator.

4*4 = 16

Our new numerator is [tex]4(2x^{12}y^{16})[/tex]

We do need to simplify the numerator one more time to get rid of the 4 outside the parentheses.

We will start with x's coefficient.

2*4 = 8

Now for y's coefficient.

1**4 = 4

*y seems to have no coefficient, but if so, it has a coefficient of 1. This applies to other variables.

Our final simplified numerator is [tex]8x^{12}4y^{16}[/tex].

Repeat with the denominator.

Try it yourself!

Make sure that when you finish, you finish the fraction.

After completing the denominator, your completed fraction should be:

[tex]\frac{8x^{12}4y^{16}}{4x^{6}2y^{18}}[/tex]

Now we can use the SEi-F to complete the problem.

Start with x.

8x - 4x = 4x

12 - 6 = 6

The first term is [tex]4x^{6}[/tex].

Now for y.

4y - 2y = 2y

16 - 18 = -2

The second term is [tex]2y^{-2}[/tex]

The complete, simplified equation is [tex]4x^{6}2y^{-2}[/tex].

I could be wrong on the answer, but the work should be correct.

Hope this helps. Have a nice day. Oh, and one more thing. Surprised I'm not stealing points?

Answer: I’m pretty sure the common factor is 15x3yStep-by-step explanation:

The best-fitting regression model for the data plot given is linear decreasing. Therefore, option B is the correct answer.

Linear regression is a linear approach for modelling the relationship between a scalar response and one or more explanatory variables. The case of one explanatory variable is called simple linear regression; for more than one, the process is called multiple linear regression.

In the given graph, the data plot shows the decreasing order.

Therefore, option B is the correct answer.

Answer:

Adter ate [tex]\frac{1}{4}[/tex] of the remaining pie.

Step-by-step explanation:

equation:

⇒ [tex]\frac{3}{4} - \frac{1}{6}[/tex]

when subtracting fractions, make sure both denominators are the same, to do this, multiply the first fraction by 3 and the second fraction by 2

⇒ [tex]\frac{3}{4} x 3 - \frac{1}{6} x 2[/tex]

⇒ [tex]\frac{9}{12} - \frac{6}{12}[/tex]

solve:

⇒ [tex]\frac{9}{12} - \frac{6}{12}[/tex]

⇒ [tex]\frac{3}{12}[/tex]

simplify:

⇒ [tex]\frac{3}{12}[/tex] = [tex]\frac{1}{4}[/tex]

The value of x that would make the relation a function is x = 3.

Option D is the correct answer.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

{ (-2, -3), (-3, -2), (2, 3), (3, 2), (x, 2) }

A function can not be one-to-many.

A function can be many-to-one and one-to-one

Now,

If x = 2, -3, -2 we get one-to-many.

But if x = 3 we get one-to-one.

Thus,

x = 3.

Answer:

  a, b, c --- all not representative

Step-by-step explanation:

The question posed by the engineer is "are residents of the city in favor of ...".

The only representative sample is one from a pool that includes all residents of the city—not just those who (a) use the road, (b) live along the road, or (c)  own homes.

Additional comment

The engineer may want to refine the question. As posed, it would include children, homeless, and/or institutionalized residents of the city as well as drivers and tax-payers. In inclusive cultural traditions, "residents of the city" may also include animals, plants, water, air, and other holders of spiritual energy.

Answer:

852 students walking to school

Step-by-step explanation:

Lets start with a simple example so you can get it

if 60% of 100 students walk to school that means

60 students walk to school... right??

so lets simplify it more that means you have multiplied 100 (students) by 60%

or [tex]\frac{60}{100}[/tex]  (note: you can say that 60% is equal to [tex]\frac{60}{100}[/tex] )

so the problem told 60% of 1420 students walk to school that means we should

do this:     [tex]1420*\frac{60}{100} = 852[/tex]

Answer:

852 walk to school

Step-by-step explanation:

i got this because i divided the 1420 into 10 which became a 142, multiply by 6 and you get 852

also you could

it is really simple also, all you have to do is multiply the number of student, S times the precent of students who walk, so s times w, which is 60 precent turend into .6 precent so 1420 x .6
