A. The greatest value with a dot above it is 11.
B. There will be 11 dots in total.
C. There will be 4 more dots above 7 than above 8.
D. There will be 5 dots above 7.
Answers
Statement " There will be 5 dots above 7" is true. Therefore, option D is the correct answer.
A line plot is an effective way to visualize and compare data in a table. In this case, the line plot would show the total number of people on each team, with dots representing the values.
The greatest value in the table is 11, but this would not be represented with a dot in the line plot. There will be 11 dots in total, representing the 11 teams listed in the table.
There will be 4 more dots above 7 than above 8, since there are 4 teams with 7 people on each team and only 3 teams with 8 people on each team.
Finally, there will be 5 dots above 7, since there are 5 teams with 7 or more people on each team.
Therefore, option D is the correct answer.

Two fair dice are rolled. What is the probability that the sum of the two numbers on the dice will be greater than 9?
A)11/12. B)5/6. C)1/12. D)1/6
Answers
Answer:
There are 36 possible outcomes when two dice are rolled (6 outcomes for the first die and 6 outcomes for the second die). To find the probability that the sum of the two numbers on the dice will be greater than 9, we need to count the number of outcomes where the sum is greater than 9.
The possible outcomes where the sum is greater than 9 are (4,6), (5,5), (5,6), and (6,5), for a total of 4 outcomes. Therefore, the probability of getting a sum greater than 9 is 4/36 or 1/9.

Huai takes out a $3700 student loan at 6.8% to help him with 2 years of community college. After finishing the 2 years, he transfers to a state university and borrows another $12,00 to defray expenses for the 5 semesters he needs to graduate. He graduates 4 years and 4 months after acquiring the first loan and payments are deferred for 3 months after graduation. The second loan was acquired 2 years after the first and had an interest rate of 7.4%. Find Huai's monthly payment when regular payments begin.

The monthly payment on loan 1 (community college) is :
Part: 0 / 30 of 3 Parts Complete
Please provide the honest answer here I can't do it and I need your help, okay thank you
To calculate the monthly payment for each loan, we need first to calculate the total amount
Answers
Huai's monthly payment for the community college loan is $89.72 and $235.35.
To calculate the monthly payment for each loan, we need first to calculate the total amount borrowed and the total interest paid for each loan.
For the first loan
Total amount borrowed = $3700
Total interest paid = $3700 x 0.068 x (4 + 4/12 + 3/12) = $1,271.12
Total amount repaid = $3700 + $1,271.12 = $4,971.12
To find the monthly payment, we can use the formula for a loan payment
P = (r(PV))/(1-(1+r)⁻ⁿ)
Where P is the monthly payment, r is the monthly interest rate, PV is the present value of the loan, and n is the total number of payments.
For the first loan, r = 0.068/12, PV = $3700, and n = 48 (4 years x 12 months/year). Substituting these values into the formula, we get
P = (0.068/12 * $3700)/(1-(1+0.068/12)⁻⁴⁸) = $89.72
Therefore, the monthly payment on the first loan is $89.72.
For the second loan
Total amount borrowed = $12,000
Total interest paid = $12,000 x 0.074 x (3/12) = $222.00
Total amount repaid = $12,000 + $222.00 = $12,222.00
The second loan was acquired 2 years after the first, so the total repayment period is 5 x 12 - 2 x 12 - 3 = 51 months.
Using the same formula as before, but with r = 0.074/12, PV = $12,000, and n = 51, we get
P = (0.074/12 * $12,000)/(1-(1+0.074/12)⁻⁵¹) = $235.35
Therefore, the monthly payment on the second loan is $235.35.

The minivan depreciates $3,000 in the first year. Write either a linear or exponential function to represent the value of the car x years after it was sold.
Answers
Answer:
Step-by-step explanation: However, say that the car loses 50% of its value every year. This means that if you originally bought a car for 2,000 dollars in 2015, in 2016 it would be world 2,000/2=1,000, 1,000/2=500 the year after that, and so on. We can try to put this into a linear function, but it's hard to put it into one equation because we're not subtracting or adding to the cost of the car by a specific amount each year. If we had our equation as y=-0.5*x+2000, this wouldn't work because it's adding to the original amount, not multiplying. However, if we used an exponential equation such as y=b(m^a), with y representing the end cost, b representing the starting cost, m representing the amount multiplied per year, and a representing the number of years. This works because we start with a value, and multiply it by an amount each year. Since 50%=0.5, we plug that into m to get y=2,000(0.5^a). Therefore, this works well here. If the minivan were to depreciate by 3,000 every year, starting at $29,248, this means that we first have to find out what we multiply by 29,248 by the first year to subtract 3,000. As, after one year, the value is 29,248-3,000=26,248, we have 26,248=29,248(m^1). Therefore, we can divide 29,248 by both sides to get around 0.9 as our answer form. Thus, our equation is y=29,248(0.9^a). This type of equation would not work if we subtracted an amount every year because we're not multiplying by the same amount then. For example, if a toy was valued at 3$ and gained a value of one dollar every year, we could multiply the toy by 4/3 the first year to get 4, but the next year we wouldn't get 5.
Determine the Y intercept:
Answers
The y-intercept of the line is 2.
In the equation y = 9x + 2, x and y are variables that represent the coordinates of any point on the line.
To find the Y-intercept, we need to find the value of y when x equals 0.
When x equals 0, the equation becomes:
y = 9(0) + 2
Any number multiplied by 0 is 0, so the first term drops out and we are left with:
y = 0 + 2
Which simplifies to:
y = 2
Therefore, when x equals 0, y equals 2. This means that the point (0, 2) is on the line. In other words, the line intersects the y-axis at y = 2, which is the Y-intercept of the line.

Let's say you wanted to make a flute from one-inch PVC pipe. If the lowest desired note is C5 on the Equal Temperament Scale (523.25 Hz), what length should it be cut?
Answers
The length the one-inch pipe should be cut to make a flute with a lowest desired note of 523.25 Hz, based on the acoustic length formula is 12.9 inches
What is the acoustic length?The acoustic length is the length obtained from the sum of the bore length and the corrections at the foot and the sound hole.
The frequency of the lowest note = 523.25 Hz
Whereby the frequency of the lowest note = The fundamental frequency
The acoustic length formula for finding the length of the pipe, L, can be presented as follows;
L = (v/(2·f)) × √(1 + 4·A²/v²)
Where;
L = The length of the pipe
f = The frequency = 523.25 Hz
A = The cross-sectional area of the pipe = π × 1.315²/4 ≈ 1.36 in²
v = The speed of sound ≈ 343 m/s ≈ 13503.9 in/s
L = (v/(2·f)) × √(1 + 4·A²/v²)
L = (13503.9/(2×523.25)) × √(1 + 4×1.26²/13503.9²) ≈ 12.9

Jada is designing a study to determine whether mold grows faster in tap water or bottled water. To do this she compares growth rate of mold growing in a glass of tap water to the growth rate of mold growing in a glass of bottled water.
What type of study is Jada designing?
How could her design be improved to collect date that would be better for answering question of interest?
Answers
Jada is directing a comparative analysis to identify whether mold thrives faster in tap water or bottled water.
How to improve her designTo upgrade her design and procure data that would be more viable for addressing the question of interest, Jada might reflect on the following:
Randomized Controlled Trial (RCT): Preferably of just contrasting the rate of growth of mold in tap water versus bottled water in a glass, Jada could arbitrarily allote separate glasses to either tap water or bottled water categories.
Replicates and Sample Size: Jada may utilize several copies for each type of water to escalate the probabilistic force of her study.
Control Group: Jada should integrate a control group in her study, where no water is integrated into the glass.

Answers
The mean number of bikes sold by the company from January to June was 146.17.
What is the mean number of bikes sold?
The mean, also called average refers to data set found by adding all numbers in the data set and then dividing by the number of values in the set.
Given data: 110 158 112 176 119 202
The total number of bikes sold is:
= 110 + 158 + 112 + 176 + 119 + 202
= 877
The number of months (Jan - Jun) = 6
The mean number of bikes sold will be:
= Ef/x
= 877 / 6
= 146.166666667
= 146.17

Which is the best reason why 2/5 is the exact quotient for 1/4 divided by 5/7
Answers
The best reason why 2/5 is the exact quotient for 1/4 divided by 5/8 is: ²/₅ * ⁵/₈ = ¹/₄
How to divide fractions?To divide fractions, firstly, you need to turn the 2nd fraction upside down. For example, 3/8 divided by 3/4 would be 3/8 divided by 4/3. After you have flipped the second fraction, you multiply them - 3*4 = 12. 8*3 = 24 so the answer would be 12/24. Which then could be cancelled down to 1/2.
Now, from the given question, we can say that:
1/4 ÷ 5/8
Now, from the earlier step in dividing fractions, the next step is to turn the 2nd fraction upside down and multiply by the first to get:
¹/₄ * ⁸/₅ = ²/₅
Rearranging, we have:
²/₅ * ⁵/₈ = ¹/₄

Answers
The area of the shaded region is 559 ft².
How to find the area of the shaded region?In order to find the area of the shaded region, we will subtract the area of the square from the area of the rectangle. That is:
area of the shaded region = area of rectangle - area of square
area of the shaded region = (32 * 20) - (9 * 9)
area of the shaded region = 640 - 81
area of the shaded region = 559 ft²
