The total amount repaid by Melvin for the specified case is given by: Option C. $1,440

For finding the total amount repaid, we need to find how repeated addition can be evaluated using multiplication.

Suppose that there are two positive integer numbers( numbers like 1,2,3,.. ) as a and b

Then, their multiplication can be interpreted as:

[tex]a \times b = a + a + ... + a \: \text{(b times)}\\\\a \times b = b + b +... + b \: \text{(a times)}[/tex]

For example,

[tex]5 \times 2 = 10 = 2 + 2 + 2 + 2 + 2 \: \text{(Added 2 five times)}\\or\\5 \times 2 = 10 = 5 + 5 \: \text{(Added 5 two times)}[/tex]

Since Melvin paid $60 for 24 months, so the amount he paid is $60 added 24 times, or:

Total amount paid by Melvin for furniture buying = 60  + 60 + ... + 60 (24 times) = [tex]24 \times 60 = 1440 \text{\: (in dollars)}[/tex]

Thus, the total amount repaid by Melvin for the specified case is given by: Option C. $1,440

The  17/4 as a mixed number can be written as  4 1/4.

For conversion from decimal to fraction, we write it in the form a/b such that the result of the fraction comes as the given decimal. Usually, to get the decimal of the form a.bcd, we count how many digits are there after the decimal point (if its finite), then we write 10 raised to that many power as denominator, and the considered number without any decimal point as numerator.

In order to make 17/4 as a mixed number, we would have to do 17 divided by 4.

17/ 4 = 4.25

Then just put that decimal into a fraction.

That would be 4.25 = 4 1/4

Therefore, the  17/4 as a mixed number can be written as  4 1/4.

Answer:

Option B - right angle

Step-by-step explanation:

We have Given statement : To trisect a(n) ____ angle, you first construct an equilateral triangle.

Solution: Option B is correct because,  a right angle is 90 degrees and an equilateral triangle has a 60 degree corner.

So, if you construct the equilateral you have one 60 and one 30, now bisect the 60.

The value of x with a z-score of -0.74 is -0.22.

To find the value of x that has a z-score of -0.74, we can use the formula:

x = mean + (z-score * standard deviation)

Given that the mean (mean) is 2 and the standard deviation (standard deviation) is 3, we can substitute these values into the formula:

x = 2 + (-0.74 * 3)

Simplifying the equation, we get:

x = 2 - 2.22

x = -0.22

Therefore, the value of x that has a z-score of -0.74 is -0.22.

Inequalities describe a range of possible values and are useful in fields like business, economics, and physical sciences. They allow for decisions based on a range of results, like determining minimum product sales for profit. However, they don't provide specific values, which is a limitation in some contexts.

Many people would be interested in using inequalities in a range of fields, including business, engineering, economics, physical sciences, and mathematics. The use of inequalities provides benefits when you need to understand a range of possible values rather than a specific number. This allows decisions to be made based on a range of acceptable outcomes.

For example, in a business setting, inequalities can be used to determine the minimum number of products that need to be sold to achieve a certain profit. If the goal is to earn at least $500, the inequality would be nx > 500, where n is the price per unit and x is the number of units sold.

However, inequalities have their limitations. They provide a range of answers, not specific solutions. Thus, they may not be suitable in situations where precise values are needed. They also imply that all values within the range are equally acceptable, which might not always be the case.

a. at r = 2

P = [10! / (10 – 2)! 2!] * 0.33^2 * 0.67^(10 – 2)

P = 0.1989 ~ 0.20               (answer)

b. We deduct the values of P when r = 0, r = 1, r = 2 from 1 to get all values when r > 2

at r = 0

P = [10! / (10 – 0)! 0!] * 0.33^0 * 0.67^(10 – 0)

P = 0.0182

at r = 1

P = [10! / (10 – 1)! 1!] * 0.33^1 * 0.67^(10 – 1)

P = 0.0898

so for r > 2, the probability is:

P = 1 – (0.1989 + 0.0182 + 0.0898)

P = 0.6931            (answer)

c. at r = 3

P = [10! / (10 – 3)! 3!] * 0.33^3 * 0.67^(10 – 3)

P = 0.2614

at r = 4

P = [10! / (10 – 4)! 4!] * 0.33^4 * 0.67^(10 – 4)

P = 0.2253

at r = 5

P = [10! / (10 – 5)! 5!] * 0.33^5 * 0.67^(10 – 5)

P = 0.1332

So when r is between 2 and 5 inclusive, the probability is:

P = 0.1989+ 0.2614 + 0.2253 + 0.1332

P = 0.8188            (answer)

The domain of the function is restricted to the altitude of the plane, and the plane cannot exceed its absolute ceiling. The graph of the function will have a vertical asymptote at the absolute ceiling. As the plane approaches its absolute ceiling, the time required to further increase its altitude increases significantly. To find the time it will take for the plane to climb to a specific altitude, substitute the altitude into the equation and solve for time.

a. The domain of the function is determined by the restrictions given in the problem. In this case, the domain represents the altitude of the plane. Since the plane's absolute ceiling is 18,000 feet, the altitude cannot exceed 18,000 feet. Therefore, the domain is 0 ≤ h ≤ 18,000.

b. To graph the function, we can plot points by substituting different values of h into the function and calculating the corresponding values of t. This will result in a smooth curve. Asymptotes occur when the function approaches certain values of h or t. In this case, the function has a vertical asymptote at h = 18,000, because the plane cannot climb beyond its absolute ceiling.

c. As the plane approaches its absolute ceiling of 18,000 feet, the time required to further increase its altitude increases significantly. This is because the logarithmic function in the equation has a slower growth rate as h approaches its limit.

d. To find the time it will take for the plane to climb to an altitude of 4000 feet, we can substitute h = 4000 into the equation t = 50 log10 (18000/(18000-h)) and solve for t.

Let us say that:

K = age of Kristen

B = age of Ben

From the problem, we make the equations:

eqtn 1: K + B = 32

eqtn 2: (K – 4) = 2 (B – 4)

Simplifying eqtn 2:

K – 4 = 2 B – 8

K = 2 B – 4

Plugging in this to eqtn 2:

(2 B – 4) + B = 32

3 B – 4 = 32

3 B = 36

B = 12

From eqtn 2:

K = 2 B – 4 = 2 (12) – 4 = 20

So Kristen is 20 while Ben is 12.

Final answer:

By translating the given information into a system of equations and solving them step-by-step, we found that Kristen is 20 years old and Ben is 12 years old.

Explanation:

The question asks us to solve a system of equations based on the ages of Kristen and Ben. The total sum of their ages is 32, and four years ago, Kristen's age was twice that of Ben. Let's denote Kristen's age as K and Ben's age as B. The given information can be translated into two equations:

K + B = 32

K - 4 = 2(B - 4)

To solve these equations, first simplify the second equation:

K - 4 = 2B - 8

K = 2B - 4

Now substitute the value of K from the second equation into the first equation:

2B - 4 + B = 32

3B = 36

B = 12

Now that we know Ben's age (12), we can find Kristen's age by substituting the value of B into any of the initial equations. Using K + B = 32:

K + 12 = 32

K = 20

Therefore, Kristen is 20 years old and Ben is 12 years old.

The probability of drawing a red marble first and a green marble second (without replacement) from a box containing 5 red, 8 green, 4 blue, and 3 yellow marbles is 2/19.

In the scenario you've described, you would first calculate the probability of selecting a red marble from the box. You have 5 red marbles and a total of 20 marbles (5+8+4+3), so the probability of drawing a red marble first is 5 out of 20, or 1/4.

When you draw a second marble without replacing the first, you have a slightly altered situation - the total number of marbles in the box now comes down to 19. We are interested in the probability of drawing a green marble now. As there are 8 green marbles, probability of drawing a green marble is 8 out of 19, or 8/19.

Probability of a red marble being picked first and then a green marble without replacement is calculated as: P(Red and then Green) = P(Red) * P(Green | Red is already picked). This equals 1/4 * 8/19 = 8/76 = 2/19.
