Michael has a substantial student debt, but he recently got a new job, which came with a signing bonus. He calculates that with his new

job, he can put aside a fixed amount of money every month to pay off his debt. He also puts the entirety of his bonus towards paying off

his debt. He constructs the expression 36, 700 - (5,000+ 500m)to represent the size of his debt after m months. Which number

describes the value of his signing bonus?

I need help plz

Answers

Answer:

Michael needs to save $63.40, approximately.

Step-by-step explanation:

The given expression is

[tex]36,700 - (5,000 + 500m)=0[/tex]

Where [tex]m[/tex] is months.

We need to solve for the variable.

[tex]36,700-5,000-500m=0\\31,700=500m\\m=\frac{31700}{500} \approx 63.4[/tex]

Therefore, Michael needs to save $63.40, approximately.

Answer:

The number representing describing the value of his signing bonus = 5,000.

Step-by-step explanation:

Total debt = $36,700

He pays $500 every month from his monthly salaries, since m = months.

The $5,000 is the amount of his signing bonus, which puts entirely towards paying off his debt.

It is like the fixed payment.  While the 500m is the variable payment per month.

So, at the end of any number of months, you can easily calculate the remaining debt using the expression, 36,700 - (5,000 + 500m)

Find the volume of the cylinder. Round your answer to the nearest tenth.

Please help!

Answers

Answer:1236.4 ft^3

Step-by-step explanation:

height=h=7ft

Diameter=15ft

Radius=r=15/2=7.5ft

Volume of cylinder=π x r^2 x h

Volume of cylinder=3.14 x (7.5)^2 x 7

Volume of cylinder=3.14x7.5x7.5x7

Volume of cylinder=1236.375

Volume of cylinder=1236.4 ft^3

On a​ team, 8 girls and 5 boys scored a total of 94 points. The difference between the number of points scored by the 8 girls and the number of points scored by the 5 boys is 34. Each girl scored the same number of points and each boy scored the same number of points. Find the number of points scored by each girl and each boy

Answers

Answer:

g = 8 points

b = 6 points

Step-by-step explanation:

If each girl scores g points, and each boy scores b points, then:

8g + 5b = 94

8g − 5b = 34

Add the equations together.

16g = 128

g = 8

Solve for b in either equation.

8(8) + 5b = 94

5b = 30

b = 6

The average mark of c
andidates in an aptitude test was 128.5 with a standard deviation of

8.2. Three scores extracted from the test are; 148, 102, 152. What is the average of the

extracted scores that are extreme values (outliers)?​

Answers

Answer:

The average of the extracted scores that are extreme values (outliers) = 102

Step-by-step explanation:

With the logical assumption that the population size is large enough, for a normal distribution,

68% of the data lies within 1 standard deviation of the mean.

95% of the data lies between 2 standard deviations of the mean.

99.7% of the data lies within 3 standard deviations of the mean.

So, the outliers for a normal distribution are usually beyond 3 standard deviations of the mean.

The mean = 128.5

Standard deviation = 8.2

The range of scores within 3 standard deviations of the mean is obtainable thus

(Mean ± 3standard deviations)

3 × standard deviations = 3 × 8.2 = 24.6

(128.5 ± 24.6) = (103.9, 153.1)

The 3 extracted scores are 148, 102 and 152. The only extreme value of these 3 extracted scores is 102. The two other scores are within the range of 3 standard deviations of the mean.

Hence, the average of the extracted scores that are extreme values (outliers) = 102

which is the equation of an asymptote of the hyperbola whose equation is (x-2)^2/4 - (y-1)^2/36 =1

Answers

Answer:C

Took the test

Step-by-step explanation:

The  equations of an asymptote of the hyperbola are y = 3x - 5 and y = -3x - 5.

What are the standard form of hyperbola and asymptotes?

The standard form of a hyperbola is:

(x-h)²/a² - (y-k)²/b² = 1

The general equation of the asymptotes for a hyperbola centered at (h,k) with semi-axes a and b is given by:

(y - k) = ± (b/a)(x - h)

To find the equations of the asymptotes of the hyperbola with equation:

(x-2)²/2² - (y-1)²/6² = 1

Plugging in the values, we get:

(y - 1) = ± (6/2)(x - 2)

Simplifying:

y - 1 = ± 3(x - 2)

y = ± 3x - 5

Therefore, the equations of the asymptotes for the given hyperbola are y = 3x - 5 and y = -3x - 5.
