Answer:

The area of the circle is 531.14 square unis

Step-by-step explanation:

Area of a circle = [tex]\pi[/tex][tex]r^{2}[/tex]

where r is the radius of the circle

Given that the diameter of the circle = 26 units, the radius can be determined by;

r = [tex]\frac{diameter}{2}[/tex]

 = [tex]\frac{26}{2}[/tex]

r = 13 units

So that,

Area of the circle = [tex]\frac{22}{7}[/tex] x [tex](13)^{2}[/tex]

                             = [tex]\frac{22}{7}[/tex] x 169

                             = 531.1429

The area of the circle is 531.14 square unis.

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:

[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: D. [tex]y=\frac{1}{9} x^{2}[/tex]

Step-by-step explanation: The smaller the coefficient of a fraction by the quadratic function (the x squared value), the more narrow the graph becomes. 1/4 is larger than 1/9 and the other two whole numbers are still larger than 1/9. Even though -1 is less than 1/9, this only makes the graph flip, not make it any more narrow. Fractions are what squeeze graphs, negatives do not make a difference (i.e. -1/4 is the same size of narrowness as 1/4).

$96 was the total cost

The Kristen's paycheck for 39 hours is $321.75.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, Kristen is paid $8.25 per hour.

Paycheck for 39 hours

= 39×8.25

= $321.75

Therefore, the Kristen's paycheck for 39 hours is $321.75.

Answer:

3 and 5

Step-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]

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:

8876-(3653 +2375)

Step-by-step explanation:

So your total is 8876. On the first and the second level of the game you scored 3653 and 2375. But when you where done playing the third level your total from all of the levels ended up to be 8876. So if you wanted to find how much points you got on level 3, then you would add 3653 + 2375, then suntract the total of that from 8876.
