15. Suppose $12,000 is borrowed for 5 years and is to be paid back with interest in one lump sum. If the annual interest
rate is 8%, what will the lump sum payment be? (Use 1= Prt)
a. $16,800.00
b. $492,000.00
c. $16,100.00
d. $17,400.00
e. $4,800.00
Answer:
Step-by-step explanation:
To solve this problem, we need to use the formula for the present value of a lump sum payment: $PV = FV \cdot (1 + r)^{-t}$, where $PV$ is the present value (the lump sum payment that needs to be made), $FV$ is the future value (the amount borrowed), $r$ is the annual interest rate, and $t$ is the number of years the money is borrowed for.In this case, we are given that $FV = 12,000$, $r = 8%$, and $t = 5$ years. Plugging these values into the formula, we get $PV = 12,000 \cdot (1 + 0.08)^{-5} = 12,000 \cdot 0.5987 = 7,184.40$.Therefore, the lump sum payment that needs to be made is $PV = \boxed{7184.40}$. The answer is $\boxed{\text{(a)}\ $16,800.00}$ is incorrect.
One interior angle of a triangle is 34°, and the other two angles are congruent. Choose the equation that could be used to determine the degree measure of one of the congruent angles. x − 34 = 90 x + 34 = 180 2x − 34 = 90 2x + 34 = 180
What is m∠C? What is m∠C?
The unknown angle in the triangle is as follows:
m∠C = 60 degrees.How to find the angle of a triangle?A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees.
A triangle can be named base on it's angles or sides. They include equilateral triangle, scalene triangle, Isosceles triangle, Right triangle, Acute triangle etc
Therefore, let's solve the angle C of the triangle as follows;
m∠C = 2x
x + 2x + 3x = 180
6x = 180
divide both sides by 6
x = 180 / 6
x = 30
Therefore,
m∠C = 2x = 2(30) = 60 degrees.

What can you conclude about the triangles? *Hint: What is congruent and how can you prove it?
The conclusion about the triangle is that the two triangles are congruent i.e they are equal
What are Congruent triangles?Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure.
In the figure, triangle ∆GHJ and ∆ GKM are the two triangles formed.
To prove that triangle GHJ = GKM
angle KGM= angle JGH ( opposite angles)
angle K = angle H (alternating angles)
Therefore angle H = angle J
since the three angles of each triangles are equal, we can say the triangles are congruent.

Answer: increasing by 0.25
Step-by-step explanation:
For the three-part question that follows, provide your answer to each question in the given workspace. Identify each part with a coordinating response. Be sure to clearly label each part of your response as Part A, Part B, and Part C.
A bag contains three blue marbles, five red marbles, and four green marbles.
Part A: What is the probability of selecting three marbles where one is blue and two are green?
Part B: What is the probability of selecting one blue marble and then selecting three red marbles?
Part C: In your own words, write a short paragraph that explains your work for Parts A and B.
The probabilities for the given problem is calculated as 0.081 and 0.06 respectively.
What is probability?Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.
The probability of any event always lie in the close interval of 0 and 1 [0,1].
The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.
Given that,
There are 3 blue marbles, 5 red marbles and 4 green marbles.
Then, the total number of marbles is 12.
The given problem can be solved as follows,
Part A:
The probability of getting 1 blue and 2 green marbles is,
P( 1 blue and 2 green) = (³C₁ × ⁴C₂)/¹²C₃
= ( 3 × 6)/ 220
= 9/110
= 0.081
Part B:
The probability of selecting one blue marble = 3/12 = 1/4
After one blue marble is selected, the remaining number of marbles is 11.
Thus, probability of selecting 3 red marbles is,
⁵C₃/¹¹C₃
= 10/165
= 0.06
Part C:
In the Part A the probability is calculated by taking the ratio of total number of ways of selecting 3 marbles and the number of ways of selecting 1 blue and 2 green marbles.
And, in Part B the number of ways is calculated from the remaining number of marbles after one blue marble is chosen.
Hence, the probabilities for the given parts in the question are 0.081 and 0.06 respectively.

A town in east Texas received 25 inches of rain in two weeks. If it kept raining at this rate for a 31-day
month, how much rain did the town receive? Round your answer to the nearest inch.
The town received approximately
inches of rain during a 31-day month.
We get approximately 56 inches of rain during a 31-day month.
What is the rate in mathematics?
In mathematics, a rate is a ratio that compares two different quantities. It is a way to express the relationship between two quantities that have different units of measure. For example, you might express the rate at which you are traveling as miles per hour, which compares the distance you have traveled (in miles) to the time it took you to travel that distance (in hours).
To find the amount of rain the town received in a 31-day month, we need to determine the daily rainfall rate and then multiply it by the number of days in the month.
The town received 25 inches of rain in two weeks, which is equal to 25/2 = 12.5 inches per week. Since there are 7 days in a week, the daily rainfall rate is 12.5/7 = 1.79 inches per day.
If it kept raining at this rate for a 31-day month, the town would receive approximately 1.79 inches per day * 31 days = 55.9 inches of rain.
Hence, we get approximately 56 inches of rain during a 31-day month.

There are 6 cards in a bag numbered 1 through 6. Suppose we draw two cards numbered A and B out of the bag(without replacement), what is the variance of A 2B
The Variance of (A +2B) is 12.6724.
What is Variance ?
Variability is measured by the variance. The average of the squared deviations from the mean is used to compute it. The degree of dispersion in your data collection is indicated by variance. The variance is greater in respect to the mean the more dispersed the data.
Here we have to select two card out of 6 card. now suppose we take 2 card (1,2 ) out of six card (1,2,3,4,5,6) . so here A=1 and B=2 but it is also possible that A=2 and B =1 because it represent same two card . Therefore here order of card matter.
Hence the posible out come of selecting 2 card are (without replacement)

mr. bell gave out a science test last week to six honors students. the scores were 88, 94, 80, 79, 74, and 83. what is the standard deviation of the scores?
The standard deviation of the scores is 6.48
For given set of scores, 88, 94, 80, 79, 74, and 83
Here, the number of observations = 6
The mean of the scores would be,
μ = Σx/n
μ = (88 + 94 + 80 + 79 + 74 + 83)/6
μ = 498/6
μ = 83
Using the formula of standard deviation,
σ = √((Xi−μ)^2)/n
σ = √[(88 - 83)² + (94 - 83)² + (80 - 83)² + (79 - 83)² + (74 - 83)² + (83 - 83)²]/6
σ = √(252/6)
