Step-by-step explanation:

For fraction multiplication, multiply the numerators and then multiply the denominators to get

4×97×20=36140

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 36 and 140 using

GCF(36,140) = 4

36÷4140÷4=935

Therefore:

47×920=935

Solution by Formulas

Apply the fractions formula for multiplication, to

47×920

and solve

4×97×20

=36140

Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(36,140) = 4

36÷4140÷4=935

Therefore:

4/7×9/20=9/35

Maria and John decide to shop for furnishings for the new house. They choose items that amount to $5600.00. The store has 2 fixed installment simple interest loan options for purchasing:

Option 1: 20% down payment and financing at 5% simple interest per year for 3 years.

Option 2: no down payment and financing at 5.25% simple interest for 4 years.

Answer each of the following questions separately, showing all your work to reach each answer.

A. Which option will result in smaller finance charge (interest)? What will that finance charge/interest be?

B. Which option will result in the smaller monthly payment on this fixed installment loan? What will that monthly payment be?

C. They decide to defer any purchases and invest a $5600 bonus that Maria will be getting from work in a savings account. The APR is 21.6% compounded monthly. How much interest will they earn in 4 years?

D. They decide to defer any purchases and loan the $5600 bonus to a needy relative at 1.5% simple interest per year. How long will the term of the loan need to be if they want to earn $500 in interest (assuming the loan is not paid off early).

Answers

Answer:

A. The option that results in the smaller finance charge/interest is option 1

B. The option that will result in the smaller monthly payment is option 1

C. The interest they will earn in 4 years, I = $6,643.972

D. The time it will take for them to earn an interest of $500 by loaning $5,600 at 1.5% is approximately 5.95 years

Step-by-step explanation:

A. The simple interest, I, formula is given as follows;

[tex]I = \dfrac{P \times R \times T }{100}[/tex]

Where;

P = The principal

R = The rate

T =The time given for the loan

For Option 1 the first option, we have;

Down payment = 0.2 × $5600.00 = $1,120.00

Principal = $5600.00 - $1,120.00 = $4,480.00

[tex]\therefore I = \dfrac{\$ 4480\times 5 \times 3 }{100} = \$672[/tex]

For Option 2. the second option, we have;

P = $5600.00

[tex]\therefore I = \dfrac{\$ 5600 \times 5.25 \times 3 }{100} = \$1176[/tex]

The option that results in the smaller finance charge is option 1

B. For option 1, the total amount = Principal + Interest

∴ The total amount remaining = $4480 + $672 = $5,152

The monthly payment = A/N

Where;

A = The total amount yet to be paid out of the loan = $5,152

N = The number of time periods = 3 × 12 = 36 months

The monthly payment = $5,152/36 = [tex]\$ 143.\overline{111}[/tex]

For option 2, the total amount = Principal + Interest

∴ The total amount remaining = $5,600 + $1176 = $6776

The monthly payment = A/N

Where;

A = The total amount yet to be paid out of the loan = $6,776

N = The number of time periods = 3 × 12 = 36 months

The monthly payment = $6,776/36 = [tex]\$ 188.\overline{222}[/tex]

Therefore, the option that will result in the smaller monthly payment is option 1

C. For a compound interest on a principal of $5,600 invested for 4 years in a savings account that gives an interest rate 21.6% per annum, we have;

[tex]A = P \times \left(1 + \dfrac{r}{n} \right)^{(n\times t)}[/tex]

We have, using the annual rate, rather than calculating for the monthly rate;

[tex]A = 5600 \times \left(1 + 0.216 \right)^{4} \approx 12243.972[/tex]

Therefore, the amount they will have in 4 years ≈ $ 12,243.972

The interest they will earn in 4 years, I = A - P ≈ $ 12,243.972 - $5,600 = $6,643.972

The interest they will earn in 4 years, I = $6,643.972

D. To earn an interest of $500 at an interest rate of 1.5%, we have;

[tex]500 = \dfrac{5600 \times 1.5 \times T}{100} = 84 \times T[/tex]

From which we have;

[tex]T = \dfrac{500}{84} = \dfrac{125}{21} = 5\frac{20}{21} \approx 5.95[/tex]

Therefore, the time it will take for them to earn an interest of $500 by loaning $5,600 at 1.5% is approximately 5.95 years.

(x^3 - x^2 - 17x -15) ÷ (x-5)

Answers

Answer:

Step-by-step explanation:

The expression x^3 - x^2 - 17x -15) ÷ (x-5) shows that x+5 is one of the factor if the polynomial function. According to factor theorem, we will equate the factor to zero and find x;

x+5 = 0

x = -5

Next is to generate the remainder.

Substitute x = -5 into the polynomial function

P(x) = x^3 - x^2 - 17x -15

P(-5) = (-5)^3 - (-5)^2 - 17(-5) -15

P(-5) = -125-25+85-15

P(-5) = -150+70

P(-5) = -80

Hence the remainder is -80

Two random variables x and y are independent if the value of x does not affect the value of y. If the variables are not​ independent, they are dependent. A new random variable can be formed by finding the sum or difference of random variables.

Answers

Answer: [tex]\mu_{x+y} =[/tex] 3026

Step-by-step explanation: Average sum of the female and male's test score is the sum of expected value of each gender:

[tex]\mu_{x+y}=\mu_{x}+\mu_{y}[/tex]

Assuming x represents the random male selected and y represents the random female selected:

[tex]\mu_{x+y}=1528+1498[/tex]

[tex]\mu_{x+y}=[/tex] 3026

The average sum of their scores is 3026.

Average difference is the difference between the expected value (mean) of each gender:

[tex]\mu_{x-y}=\mu_{x}-\mu_{y}[/tex]

[tex]\mu_{x-y}=[/tex] 1528 - 1498

[tex]\mu_{x-y}=[/tex] 30

The average difference of their scores is 30.

Photos and videos have become an important part of the online social experience, with more than half of Internet users posting photos or videos online that they have taken themselves. Let A be the event an Internet user posts photos that they have taken themselves, and B be the event an Internet user posts videos that they have taken themselves. A research center finds that P(A) = 0.47, P(B) = 0.28,and P(A or B) = 0.52.

Required:
What is the conditional probability that an Internet user posts photos that they have taken themselves, given that they post videos that they have taken themselves?

Answers

Answer:

0.82

Step-by-step explanation:

Given:

A be the event that an Internet user posts photos taken by themselves.

B be the event that an Internet user posts photos taken by themselves.

P(A) = 0.47

P(A) = 0.28

P(A or B) = [tex]P(A\cup B)[/tex] = 0.52

To find:

Conditional probability that an Internet user posts photos given that they post videos.

OR

P(A/B) = ?

Solution:

Formula to be used to find the required conditional probability:

[tex]P(A/B) = \dfrac{P(A \cap B)}{P(B)}[/tex]

For this, [tex]P(A \cap B)[/tex] is required.

Formula

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

[tex]0.52=0.47+0.28-P(A\cap B)\\\Rightarrow P(A\cap B)=0.23[/tex]

Now, the required conditional probability is:

[tex]P(A/B) = \dfrac{P(A \cap B)}{P(B)}\\\Rightarrow P(A/B) = \dfrac{0.23}{0.28}\\\Rightarrow \bold{P(A/B)} = 0.82}[/tex]

So, the answer is 0.82.

a random sample of 21 students from U and 21 students at A&T for surveyed their music listening habits. Their responses (IN HOURS, each square represents 0.5 hour) were record and displayed using the following histograms. The one on the left is from U and the one on the right is for A&T students. Which data set (the U students or the SHSAT students) has a larger standard deviation? Explain!​

Answers

The numbers are a bit blurry so I can't determine the numeric standard deviation for each set. However, we can see that the histogram on the left has an outlier, which will increase the standard deviation compared to the data set that doesn't have an outlier. Therefore it is likely data set U has a larger standard deviation.

Determine the slope of line (AB) and the slope of line (CD). Determine whether line (AB) and line (CD) are parallel, perpendicular, or just intersecting (neither). Points A and B line on the line y = 2/3x + 4. Points C and D line on the line 6x + 4y = 16.

Answers

Answer:

The slopes are perpendicular

Step-by-step explanation:

Points A and B line on the line y = 2/3x + 4.

This line is in the form

y = mx+b where m is the slope

The slope is 2/3

Points C and D line on the line 6x + 4y = 16.

Solve for y

6x+4y = 16

4y = -6x +16

Divide by 4

4y/4 = -6/4x + 16/4

y = -3/2 x +4

The slope is -3/2

The slopes multiply to -1

2/3 * -3/2 = -1

so they are perpendicular
