Alex’s monthly take home pay is $2,500. What is the maximum bad debt payment he can maintain without being in credit overload?
A): $250
B): $325
C): $475
D): $500

Answers

Answer:

it's d I agree with other person that answered

The solution is Option D.

The maximum bad debt payment Alex can maintain without being in credit overload is given by the equation A = $ 500

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the maximum bad debt payment Alex can maintain without being in credit overload be A

Let the take home pay of Alex be = $ 2,500

The percentage of maximum debt payment be = 20 %

Now , the equation will be

Maximum bad debt payment Alex can maintain without being in credit overload A = take home pay of Alex x percentage of maximum debt payment

Substituting the values in the equation , we get

Maximum bad debt payment Alex can maintain without being in credit overload A = 2500 x ( 20/100 )

On simplifying the equation , we get

Maximum bad debt payment Alex can maintain without being in credit overload A = 2500 x 0.20

Maximum bad debt payment Alex can maintain without being in credit overload A = $ 500

Therefore , the value of A is $ 500

Hence , the Maximum bad debt payment is $ 500

At a party there are 30 students over age 21 and 20 students under age 21. You choose at random 3 of those over 21 and separately choose at random 2 of those under 21 to interview about attitudes toward alcohol. You have given every student at the party the same chance to be interviewed: what is that chance

Answers

Answer:

10%

Step-by-step explanation:

According to the scenario, given data are as follows:

Students over age 21 = 30

Students under age 21 = 20

Choose student over age 21 = 3

Choose student under age 21 = 2

So, we can calculate chances by using following method,

Chances of student over age 21 = Number of choose student ÷ Total students

= 3 ÷ 30  = 0.10 = 10%

Similarly, Chances of student under age 21 = Number of choose student ÷ Total students

= 2 ÷ 20  = 0.10 = 10%

Hence, in both condition, chances are 10%.

The answer to the question is C

The length of a rectangular table is 3 times its width. If the total perimeter of the table is 36 meters. What is the length and the width of the table?

Answers

Answer:

Length = 13.5 m

Width = 4.5 m.

Step-by-step explanation:

Use an equation in x, where x = width of the table.

Length =  3x, so:

2*3x + 2x = 36

6x + 2x = 36

8x = 36

x = 36/8 =  4.5 metres.

So the length = 3*4.5 = 13.5 and width = 4.5 m.

Length = 13.5 m

Width = 4.5 m.

What is the perimeter?

A closed route that covers, encircles, or outlines a one-dimensional length or a two-dimensional form is called a perimeter.

Given, The length of a rectangular table is 3 times its width. If the total perimeter of the table is 36 meters.

Use an equation in B, where B = width of the table.

Length =  3B,

2*3B + 2B = 36

6B + 2B = 36

8B = 36

B = 36/8 =  4.5 meters.

So the length = 3*4.5 = 13.5 and width = 4.5 m.

Therefore, the length and the width of the given rectangle are 4.5 and 13.5 respectively.

0.2220

0.2339

0.7653

0.7780

Answers

Answer:

0.7780

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

When the distribution is normal, we use 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.

Population:

We have that [tex]\mu = 7.19, \sigma = 0.86[/tex]

Sample of 12:

[tex]n = 12, s = \frac{0.86}{\sqrt{12}} = 0.2483[/tex]

What is the probability that the mean cost will be more than $7.00?

This is 1 subtracted by the pvalue of Z when X = 7. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{7 - 7.19}{0.2483}[/tex]

[tex]Z = -0.765[/tex]

[tex]Z = -0.765[/tex] has a pvalue of 0.222

1 - 0.222 = 0.778

So the answer is 0.7780

D If a quadrilateral is a parallelogram, then both pairs of opposite sides of the

Answers

Answer:

B If a quadrilateral has diagonals that bisect each other, then the quadrilateral is a parallelogram

Explanation:

A rectangle just like a square has diagonals that bisect each other and they are congruent( two lines are congruent if they are equal). A parallelogram is a quadrilateral with parallel sides and when its diagonals intersect, they are congruent too. Therefore a rectangle with diagonals that bisect each other is not necessarily a parallelogram.

Sara has 2 pounds of chicken. She uses 5 ounces of chicken while cooking. How can you determine the mass of chicken that she has left?

Answers

Answer: 27 ounces of chicken.

Step-by-step explanation:

Sara has 2 pounds of chicken.

She uses 5 ounces of chicken.

So now, she has:

(2 pounds - 5 ounces ) of chicken.

To perform this subtraction, we first need to write bot quantities in the same units.

First, we know that:

1 pound = 16 ounces.

Then we can rewrite 2 pounds, this is equal to 2 times 16 ounces.

2 pounds = 2*16 ounces = 32 ounces.

Then initially she has 32 ounces, and she uses 5 ounces.

Now she has:

(32 ounces - 5 ounces) = 27 ounces of chicken

Using sides of a triangle rule, the inequality gives the range of possible values for x is  5 < x < 9.

What is sides of a triangle rule?

The sides of a triangle rule asserts that the sum of the lengths of any two sides of a triangle has to be greater than the length of the third side.

Given that two sides of triangle are 2 and 7 inches.

Let the third side be x inches.

x < 2+7 ⇒ x < 9

7 < 2 + x ⇒ x > 5

2 < 7 + x, which is true for any positive value of x.

Thus,  5 < x < 9.
