Answer:
[tex]k = 7[/tex]
Step-by-step explanation:
Given
[tex]g(x) = f(x) + k[/tex]
Required
The value of k
From the attached graph, line f(x) is shifted up 7 times to match g(x).
This implies that:
[tex]g(x) = f(x) + 7[/tex]
Compare: [tex]g(x) = f(x) + k[/tex] and [tex]g(x) = f(x) + 7[/tex]
[tex]k = 7[/tex]
(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.

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.

Henri’s potato vine is growing like crazy! When he planted it, it was 15 inches long. Two weeks later, it was 22 inches long. Four weeks after that, it was 36 inches long. Write an equation to represent this situation.
Answer:
1x = 7
Explanation:
Every week it grows 7 total inches. So, "x" stands for week. The equation "1x = 7" means 1 week equals 7 inches. This is the simplest equation to write this problem.

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.

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.

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 National Institute of Mental Health published an article stating that in any one-year period, approximately 9.5 percent of American adults suffer from depression or a depressive illness. Suppose that in a survey of 100 people in a certain town, seven of them suffered from depression or a depressive illness. If you were conducting a hypothesis test to determine if the true proportion of people in that town suffering from depression or a depressive illness is lower than the percent in the general adult American population, what would the null and alternative hypotheses be? (Note = refer to top of page 508 for format and appropriate equality and non-equality symbols, respectively)a. H0 :______b. Ha :______
Answer:
a) [tex]H_{0} = 9.5[/tex]
b) [tex]H_{a} < 9.5[/tex]
Step-by-step explanation:
The National Institute of Mental Health published an article stating that in any one-year period, approximately 9.5 percent of American adults suffer from depression or a depressive illness.
At the null hypothesis, we test if the value we find is equal to the expected value, that is:
[tex]H_{0} = 9.5[/tex]
Test to determine if the true proportion of people in that town suffering from depression or a depressive illness is lower than the percent in the general adult American population
Lower, which means that the alternate hypothesis, we test if the value we find is lower than the expected value, that is:
[tex]H_{a} < 9.5[/tex]
