David has a monthly after-tax income of $ 1430.15 1430.15 . He will be using the companies health insurance plan which costs $ 63 63 a monthand the retirement option which takes 7 7 % of his after tax income. Calculate David's Monthly Take-Home pay.
Answers
Answer:
$ 1267.
Step-by-step explanation:
Given :
David's monthly income after tax = $ 1430.15
His health insurance cost him in a month = $ 63
Percent deducted from his income after tax for his retirement option is = 7%
Therefore money left after retirement option deduction is :
$ 1430.15 - 7% of $ 1430.15
= 1430.15 - 100.11
= $ 1330.04
= $ 1330 (aprrox)
Money deducted from this amount for his health insurance plan
= $ 1330 - $ 63
= $ 1267
Therefore, David's monthly take home pay is $ 1267.

Answer and Step-by-step explanation:
When we take a look at the graph, we can see that at around 1 gallon, which would be halfway between 0 and 2, the line is underneath $5.
That means we can eliminate any number that is or above $5.
That leaves us with answer choices A and C.
Let's go to a point that is easily readable. Point (4, 15) is readable, and we can use this to find the price per gallon.
Divide 15 by 4. We get 3.75 as the result.
This means that the answer choice is:
C. The cost of gas is $3.75 per gallon.

Cyber Monday Shopping A survey of 1000 U.S. adults found that 33% of people said that they would get no work done on Cyber Monday since they would spend all day shopping online. Find the 95% confidence interval of the true proportion.
Answer:
(0.301 ; 0.359)
Step-by-step explanation:
Sample size, n = 1000
Phat = 0.33
(1 - phat) = 1 - 0.33 = 0.67
Zcritical at 95% = 1.96
Confidence interval :
Phat ± margin of error
Margin of Error = Zcritical * sqrt[(phat(1 - phat)) /n]
Margin of Error = 1.96 * sqrt[(0.33 * 0.67) / 1000]
Margin of Error = 1.96 * 0.0148694
Margin of Error = 0.0291440
Lower boundary = (0.33 - 0.0291440) = 0.300856
Upper boundary = (0.33 + 0.0291440) = 0.359144
(0.301 ; 0.359)
In the third quarter of 2001, the median sale price for a single-family
home in Putnam County, New York, was $259,970. A year earlier, the
price was $242,555. What was the percent increase?
Answers
Answer:
The % increase is 7.179 but see the remark I made below. What I have given and what it could be is a rounding error. Less than 2 dollars error is not much when you are calculating something for someone just to show them how to do it.
Step-by-step explanation:
242,555 * x/100 = 259,970 Multiply by 100
242,555 * x = 259970 * 100
242,555 * x = 25997000 Divide by 242555
x = 24997000/242444
x = 107.179
That's the total increase.
What you want is 7.179%
If you take 7.179% of 242,555 and add it onto 242555 you should get 259,970
7.1797/100 * 242555 = 17413.02
17413.02 + 242555 = 259968.02
Why isn't it exact. I'm out just about 2 whole dollars. The reason is that the % isn't exact. It's only out to 3 decimal places which apparently is not enough. You can go over my numbers if you want more exactness us use something that is rounded to 7.180 if you like.

O A. The value of n can be any positive integer resulting in the same factor
O B. The value of n can be any positive integer resulting in the distinct factors

O
D. The value of n can be any prime integer resulting in the distinct factors
(Use a comma to separate answers as needed.)
O E. The expression cannot be factored for the given values of n.
Answers
Answer:
A. The value of n can be any positive integer resulting in the same factor
Step-by-step explanation:
Given
[tex]x^2 + 2xn + n^2[/tex] --- the right expression
[tex]n > 0[/tex]
Required
Possible values of n
[tex]x^2 + 2xn + n^2[/tex]
Expand
[tex]x^2 + 2xn + n^2 = x^2 + xn+xn + n^2[/tex]
Factorize
[tex]x^2 + 2xn + n^2 = x(x + n)+n(x + n)[/tex]
Factor out [tex]x + n[/tex]
[tex]x^2 + 2xn + n^2 = (x + n)(x + n)[/tex]
From the expression above, we can see that the result has the same factor. This means that options (b), (d) and (e) are not possible
[tex]x^2 + 2xn + n^2 = (x + n)^2[/tex]
The above also shows that n can take any positive value.
Hence: (a) is correct
