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?

(NOT A MULTIPLE CHOICE)
Suppose a civic engineer wants to conduct a survey to find out if residents of a city would be in favor of widening one of the city's roadways for increased traffic flow
a. Would a sample consisting of residents who utilize that roadway to travel to work each morning be representative? Explain.
b. Would a sample consisting of residents who live along that roadway be representative? Explain.
c. Would a random sample of homeowners in the city be representative? Explain.
9514 1404 393
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.

You would need to multiply them together because it then gives you how much it is off.
Then then you would subtract it.
That takes D and C off.

Fon baked a cake and ate 1/8 of it she shared the remaining cake equally to her 4 friends whag Frection of the whole cake did each of her friends received?
Answer:
Each of her friends ate 7/32 of the cake.
Step-by-step explanation:
Given that Fon baked a cake and ate 1/8 of it, and then she shared the remaining cake equally to her 4 friends, to determine what fraction of the whole cake did each of her friends received, the following calculation must be performed:
(8 - 1/8) / 4 = X
(7/8) / 4 = X
(28/32) / 4 = X
7/32 = X
Thus, each of her friends ate 7/32 of the cake.

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. The distribution of the monthly costs does not follow the normal distribution. In fact, it is positively skewed. 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
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.

Which graph shows a linear relationship? Select yes or no. For A B C D
Answer:
A, B, and C show linear relationships.
Step-by-step explanation:
For something to have a linear relationship, it CANNOT have an x-value with two different y-values.
To determine if something has two y-values for one x-value, pass a line (like a pencil) over the graph. If there are any places where the line crosses the graph twice, the graph you have is not linear.
Can Someone Plz Help me???!!!
The Answers are
A 480
B 360- IT’S NOT B!
C 272
D 368
Plz Help Me!!
Answer:
D) 368
Step-by-step explanation:
you already have 2 of the sides of WXYZ (120 is the length of both long sides). to get the length of the shorter side (YZ), you can solve for the 3rd side of the triangle WYZ using the pythagorean theorem, which states that the square root of the different between the square of the hypotenus (the line YW, which is 2 * 68 for WYZ) and the square of the known side (WZ, which is 120 here) is equivalent to the unknown side (YZ). using that info,[tex]\sqrt\\(2 *68)^{2} - 120^{2}[/tex] = 64, so 64 is the length of YZ. the perimeter of WXYZ is (2 * WZ) + (2 * YZ) = (2 * 120) + (2 * 64) = 368. therefore, the perimeter of WXYZ is 368!
What value of x would make the following relation a function?
Answer: the answer is
C.) -2
Step-by-step explanation:
I got this answer by simply looking at the pattern. It goes -2,-3,2,3, and then starts over, So the answer would have to be -2. I hope this helped and good luck:))
The value of x that would make the relation a function is x = 3.
Option D is the correct answer.
What is a function?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.
