Answer:
[tex]y=\frac{1}{4} x+3.[/tex]
Step-by-step explanation:
1. if the points (-4;2) and (12;6) belong to the required line, then it is possible to make up its equation:
[tex]\frac{x+4}{12+4} =\frac{y-2}{6-2}; \ \frac{x+4}{4}=\frac{y-2}{1};[/tex]
2. if the common form of line in slope-interception form is 'y=s*x+i' (where s - slope, i - interception), then after evaluation of the equation in item 1:
4(y-2)=x+4; ⇒ 4y=x+12; ⇔
[tex]y=\frac{1}{4}x+3.[/tex]

Answer:
B. 1.5 = 2p
Step-by-step explanation:
If p is the fraction of the price of a pizza, then 2p is the actual value of that fraction. We're told that is equal to the price of a hotdog, so ...
2p = 1.5
or
1.5 = 2p . . . . . . matches choice B
_____
Additional comment
Some of us would "cut to the chase" and compute the fraction directly:
p = (price of hotdog)/(price of pizza) = 1.5/2
No such choice is offered, so the next best is the equation you get when you multiply this by 2:
2p = 1.5
Which number makes the equation true?
Answer:
6 is the answer

At what rate does a payment plan for $1,500 accumulate $450 interest after 6 years?
Answer:
At a rate of 5%.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
[tex]E = P*I*t[/tex]
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
In this question:
Payment plan for $1500 means that [tex]P = 1500[/tex]
$450 interest after 6 years means that [tex]E = 450, t = 6[/tex]
We have to find the rate I. So
[tex]E = P*I*t[/tex]
[tex]450 = 1500*I*6[/tex]
[tex]I = \frac{450}{1500*6}[/tex]
[tex]I = 0.05[/tex]
At a rate of 5%.

34, 29, 28, 16, 19, 18, 34, 33, 29
Find the range of the data set
Answer:
34-16=18
so 18
Answer:
18
Step-by-step explanation:
First, order the data set from least to greatest:
16, 18, 19, 28, 29, 29, 33, 34, 34
The range of a given data set can be found by subtracting the greatest number (34 in this case) with the least number (16) in the set:
34 - 16 = 18
18 is your answer.

Analyzing O! Pioneers
Willa Cather’s 1910 novel, O! Pioneers, follows a Swedish family of farmers in Nebraska.
In this passage, John Bergson is dying and worries about what will become of his wife and
young children. Alexandra is the oldest Bergson child
Alexandra, her father often said to himself, was like her grandfather; which was his
way of saying that she was intelligent. John Bergson’s father had been a shipbuilder, a
man of considerable force and of some fortune. Late in life he married a second time, a
Stockholm woman of questionable character, much younger than he, who goaded him into
every sort of extravagance. On the shipbuilder’s part, this marriage was an infatuation,
the despairing folly of a powerful man who cannot bear to grow old. In a few years his
unprincipled wife warped the probity of a lifetime. He speculated, lost his own fortune
and funds entrusted to him by poor seafaring men, and died disgraced, leaving his
children nothing. But when all was said, he had come up from the sea himself, had built
up a proud little business with no capital but his own skill and foresight, and had proved
himself a man. In his daughter, John Bergson recognized the strength of will, and the
simple direct way of thinking things out, that had characterized his father in his better
days. He would much rather, of course, have seen this likeness in one of his sons, but it
was not a question of choice. As he lay there day after day he had to accept the situation
as it was, and to be thankful that there was one among his children to whom he could
entrust the future of his family and the possibilities of his hard-won land.
Discuss the Meaning
Alexandra shares personal qualities with her grandfather. What are these qualities and
how will they help the Bergson family survive after her father dies? Cite text examples to
support your ideas.

Jean works for the government and was conducting a survey to determine the income levels of a number of different neighborhoods in a metropolitan area. Based on national data, Jean knows that the mean income level in the country is $40,000, with a standard deviation of $2,000. Jean selected three neighborhoods and determined the average income level. What is the probability that the average income level in the neighborhoods was less than $38,000
Answer:
0.0418 = 4.18% probability that the average income level in the neighborhoods was less than $38,000.
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.
Jean knows that the mean income level in the country is $40,000, with a standard deviation of $2,000.
This means that [tex]\mu = 40000, \sigma = 2000[/tex]
Jean selected three neighborhoods and determined the average income level.
This means that [tex]n = 3, s = \frac{2000}{\sqrt{3}} = 1154.7[/tex]
What is the probability that the average income level in the neighborhoods was less than $38,000
This is the pvalue of Z when X = 38000. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{38000 - 40000}{1154.7}[/tex]
[tex]Z = -1.73[/tex]
[tex]Z = -1.73[/tex] has a pvalue of 0.0418
0.0418 = 4.18% probability that the average income level in the neighborhoods was less than $38,000.

What is the solution to 9x−6<21?
Select one:
x<4
x<3
x<2
x<5
Answer:
[tex]x > 3[/tex]
Step-by-step explanation:
1) Add 6 to both sides.
[tex]9x > 21 + 6[/tex]
2) Simplify 21 + 6 to 27.
[tex]9x > 27[/tex]
3) Divide both sides by 9.
[tex]x > \frac{27}{9} [/tex]
4) Simplify 27/9 to 3.
[tex]x > 3[/tex]
Therefor, the answer is option B. x > 3.
