A credit card holder has an outstanding balance on four different credit cards. Which method of paying off the credit card will take the longest period of time? Making fixed payments each month Paying the minimum balance each month Snowballing payments according to the highest interest rate Snowballing payments according to the lowest balance

Set up as a system of equations,

Let x represent the number of 4 credit courses and y represent the 3 credit courses.

The total number of courses the student took was 15. So we can say[tex]x+y=15[/tex]

The total credits earned was 54. So we can say, [tex]4x+3y=54[/tex]

Now we have the following system of equations, solve for the value of x.

[tex]\left \{ {{x+y=15} \atop {4x+3y=54}} \right.[/tex]

Take the top equation and solving for y. We get,

=> [tex]x+y=15[/tex]

=>[tex]y=15-x[/tex]

Take the value of y above and plug it into the second equation.

=> [tex]4x+3y=54[/tex]

=> [tex]4x+3(15-x)=54[/tex]

=> [tex]4x+45-3x=54[/tex]

=> [tex]x+45=54[/tex]

=> [tex]x=54-45[/tex]

=> [tex]x=9[/tex]

Thus, the student took 9, 4 credit classes.

The side length of quadrilateral WXYZ are

|WX| = 4.47

|XY| = 2

|YZ| = 4

|ZW| = 4

The perimeter of quadrilateral WXYZ is 14.47 units.

The four points W, X, Y, and Z are located at ponts (3,1), (7,-1), (7,-3), and (3,-3) respectively.

To find the distance between two points, A and B, with coordinates (x1, y1) and (x2, y2) respectively, we use the formula:

|AB|=√(x2 – x1)² + (y2 – y1)²

The side lengths of the quadrilateral are calculated using this formula.

|WX| = √(– 1 – 1)² + (7 – 3)² = 4.47

|XY| = √(– 3 – (– 1))² + (7 – 7)² = 2

|YZ| = √(– 3 – (– 3))² + (3– 7)² = 4

|ZW| = √(– 3 – 1)² + (3 – 3)² = 4

Hence, the Perimeter of the quadrilateral = |WX| + |XY| + |YZ| + |ZX| = 4.47 + 2 + 4 + 4 = 14.47 units

Step-by-step explanation:

The plane's distance is the hypotenuse of a right triangle with legs of

(50 -20)mi = 30 miles     and     30500 - 18000 = 12500 ft

                             for consistent units  12500ft/5280ft/mile = 2.36742 miles

Now just use Pythagorean theorem

Hypotenuse^2 = leg1^2 + leg2^2

There are 252 different ways that the combination of 5 heads and 5 tails can occur. The coefficient for this term in the binomial equation is [tex]\mathrm{10C_x}[/tex]

The binomial theorem is a mathematical result that describes the expansion of the power of a binomial expression. A binomial expression is an expression that consists of two terms, such as (x + y) or (a + b). The binomial theorem states that for any positive integer n, the expansion of the expression (x + y)^n will contain exactly n+1 terms, each of which is a power of x multiplied by a coefficient.

If we want 5H and 5T,hence there are 10 trials.

Hence it is similar to choosing 5 out of 10 or choosing 2 similar sets of 5 each out of 10 in 10C5 ways:

[tex]$\mathrm{10C_5=\frac{10!}{5!(10-5)!}=252}[/tex]

The coefficient is actually the number of ways of choosing the 5 out of 10.

Solving a system of equations we will see that they sold 184 adult tickets.

We know that the theater sells two types of tickets:

adult tickets for $8 and child tickets for $4.

The variables that we will use are:

x = number of adult tickets sold.

y = number of child tickets sold.

Then we can write the cost revenue equation as:

8x + 4y = 1900

And the total number of tickets sold is 291, then:

x + y = 291

Then we have a system of equations:

8x + 4y = 1900

x + y = 291

We can isolate y on the second equation to get:

y = 291 - x

Replacing that on the other equation we will get:

8x + 4*(291 - x) =1900

4x + 1164 = 1900

4x = 1900 - 1164 =736

x = 736/4 = 184

Answer: B. The environment of the zoo may cause the lions to behave

differently than they would in a natural habitat.  

                                         and

D. The presence of the researchers may affect the lions' behavior.

Step-by-step explanation:  Studying lion behavior in zoos has limitations. The artificial environment of a zoo can affect how lions behave compared to their behavior in the wild.  Additionally, the presence of researchers may influence the lions' behavior, making it difficult to observe and understand their natural interactions.

B. The environment of the zoo may cause the lions to behave differently than they would in a natural habitat.

In a zoo, lions are confined to a limited space and are provided with a controlled environment.  This artificial setting may not accurately reflect their natural habitat and can influence their behavior.  For example, the availability of food, different social dynamics, and reduced hunting opportunities in a zoo can lead to altered behaviors that may not be representative of how lions behave in the wild.

D. The presence of the researchers may affect the lions' behavior.

When researchers observe animals in a zoo, their presence can influence the behavior of the lions.  The presence of unfamiliar humans can cause the animals to become more cautious, stressed, or exhibit abnormal behavior.  This could potentially alter the social interactions and dynamics observed by the researchers, making it challenging to accurately understand and interpret natural lion behavior.

The significance level is an factor in hypothesis testing and helps us determine the likelihood of making a Type I error.

A significance level is a critical value in hypothesis testing that determines the probability of making a Type I error, which is rejecting a null hypothesis when it is actually true.

To test whether a specific slope coefficient is equal to one, we can perform a t-test to see if the estimated slope coefficient is significantly different from one at a certain significance level.

The null hypothesis for this test is that the slope coefficient is equal to one, and the alternative hypothesis is that it is not equal to one.

We can use the t-statistic to determine the level of significance for the estimated slope coefficient. The t-statistic is calculated by dividing the estimated slope coefficient minus one by the standard error of the slope coefficient.

The resulting t-value is then compared to the critical t-value from a t-distribution table with the appropriate degrees of freedom.

If the t-value is less than the critical t-value, we fail to reject the null hypothesis and conclude that the estimated slope coefficient is not significantly different from one at the 5% significance level.

On the other hand, if the t-value is greater than the critical t-value, we reject the null hypothesis and conclude that the estimated slope coefficient is significantly different from one at the 5% significance level.

(a) To find the product of 1/2x-1/4 and 5x^2-2x+6, we can use the distributive property of multiplication:

(1/2x - 1/4)(5x^2 - 2x + 6)

= (1/2x)(5x^2) + (1/2x)(-2x) + (1/2x)(6) - (1/4)(5x^2) + (1/4)(2x) - (1/4)(6)

= (5/2)x^2 - x + 3 - (5/4)x + (1/2)x - (3/2)

= (5/2)x^2 - (3/4)x + 3/2

Therefore, the product of 1/2x-1/4 and 5x^2-2x+6 is (5/2)x^2 - (3/4)x + 3/2.

(b) No, the product of 1/2x-1/4 and 5x^2-2x+6 is not equal to the product of 1/4x-1/2 and 5x^2-2x+6. This is because when we expand both products using the distributive property, we get different expressions:

(1/2x - 1/4)(5x^2 - 2x + 6) = (5/2)x^2 - (3/4)x + 3/2

(1/4x - 1/2)(5x^2 - 2x + 6) = (5/4)x^2 - (7/4)x + 3

So the coefficients of the x^2 and x terms in the two products are different. Therefore, the two products are not equal.

                          Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

a.

Commission can be referred to as the reward given by the company on goods for the employee to sell products in order to make more sales and more money.

Commission is calculated as follows:

Total commission = Total Sales * Commission Percentage

Given

Total Sales = $495

Commission Percentage = 5½%

Substitute in, the above values

Total Commission = $496 * 5½%

Total Commission = $496 * 5.5%

Total Commission = $496 * 0.055

Total Commission = $27.28

Hence, the total commission is calculated as $27.28

b. The amount remitted to the store is calculated as

Amount = Total Sales - Total Commission

Where Total Sales = $496

Total Commission = $27.28

Amount = $496 - $27.28

Amount = $468.72

Hence, the store will get $468.72 from the sale of the couch.
