William needs to take out a loan for $2,400. Which of these payment plans would have William
paying the last interest
A 18 payments of $144.15
8 12 Payments of $211
C 15 payments of $170.88
D payments of $110.75

Answers

12 payments of 211 because interest is primarily based on how long it will take you to pay back the loan, so the longer you take, the more interest you pay

In how many ways can 5 people arrange themselves in a row for picture taking ?

Answers

Answer:

120 times

Step-by-step explanation:

There are 5 people to fill the first place, 4 remaining to fill the second, 3 remaining to fill the third, 2 remaining to the fourth place and only 1 remaining to fill the fifth. That means there are 5 factorial (5!) ways. 5! = 5 x 4 x 3 x 2 x 1 = 120.

A point is chosen at random on AK what is the probability that the point will be on FI don't reduce

Answers

Answer: 3/10

Step-by-step explanation:

The probability that the point will be on FI is 3/10 if a point is chosen at random on AK the answer is 3/10.

What is probability?

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We have a number line shown in the picture:

Total Number partition or gaps between each letter(between A and K):

= 10

Total number of outcomes = 10

Total number of favorable outcomes(between F and I) = 3

The probability that the point will be on FI:

By using the definition of the probability:

= favorable outcomes/total outcomes

= 3/10

Thus, the probability that the point will be on FI is 3/10 if a point is chosen at random on AK the answer is 3/10.

Step-by-step explanation:

The standard form equation for a circle with center (h, k) and radius r is ...

  (x -h)^2 + (y -k)^2 = r^2

For your center and radius, the equation is ...

The associative property states that numbers can be added or multiplied regardless of their paratheses. This means that how the numbers are grouped can change and still be equal. Another example of this would be [tex]2+(6+5)=(2+6)+5[/tex]. In both equations the sides are balanced.

In some 4.0 grading systems, a student's grade point average (GPA) is calculated by assigning letter grades the following numerical values.
A = 4.00 B− = 2.67 D+ = 1.33
A− = 3.67 C+ = 2.33 D = 1.00
B+ = 3.33 C = 2.00 D− = 0.67
B = 3.00 C− = 1.67 F = 0.00
Use this grading system to find this student's GPA. Round to the nearest hundredth.

Step-by-step explanation:

Student's GPA:

To find the students GPA, we find the sum of the multiplication of each numerical grade(A is 4, A- is 3.67 and so on) and the credit load of the course, divided by the number of courses.

His grades are:

4 in English worth 3 credits.

4 in Antropology worth 3 credits.

2.67 in Chemistry worth 4 credits.

2 in French worth 4 credits.

3 in Theatre worth 2 credits.

GPA:

On Monday, 248 students went on a trip to the zoo. All 6 buses were filled and 8 students had to travel in cars. How many students were in each bus?​

Answers

Answer:

40 students in each bus.

Step-by-step explanation:

Subtract the 8 extra students from the total to get the total number of students who rode in buses. Then divide that total by 6.

248-8=240

240/6=40

40 students in each bus.

248-8=240
240/6=40
= 40 students in all six buses

Four members of a relay team evenly split the distance of a race. Each person ran more than 100 meters. Which inequality can be used to represent d, the total distance the group ran?
4 d greater-than 100
4 d less-than 100
StartFraction d Over 4 EndFraction greater-than 100
StartFraction d Over 4 less-than 100

Answers

Answer:

The answer would be C.

Step-by-step explanation:

Since each person ran more than 100 meters, the answer would be greater than 100.

d is the total distance the group ran, not the individual distance, so it couldn't be 4d because that would mean it would be 4 times d.

The answer would be d divided by 4. d/4. That is because the total distance divided by 4 would be the individual distance.

Step-by-step explanation:

It looks like every time the coefficient increases by 3 while the exponent increases by 1.

[tex]\\45\\\sum 3(n+1)x^{n}\\n = 0[/tex]

Notice it starts at zero so 3 is multiplied by (x+1) to make it start from 0

The exponent is simply n, because at the start is it zero [tex]x^0=1[/tex], then 1, then 2, so on.

The upper limit is 45 because 45 - 0 = 45 terms

The hypotenuse of a right triangle is twice the length of one of its legs. The length of the other leg is three feet. Find the lengths of the three sides of the triangle. Enter an exact answer. Do not type your answers as fractions or decimals.

Answers

a^2 + b^2 = c^2

Let c = hypotenuse = 2x

One of the legs = x. Let a or b = x.

I will let a = x. We can then say that b = 3.

3^2 + x^2 = (2x)^2

9 + x^2 = 4x^2

9 = 4x^2 - x^2

9 = 2x^2

9/2 = x^2

sqrt{9/2} = sqrt{x^2}

3/sqrt{2} = x

Rational denominator.

[3•sqrt{2}]/2 = x = a

Side 3 is given to be 3 feet. So, b = 3.

Hypotenuse = 2x

Hypotenuse = 2([3•sqrt{2}]/2)

Hypotenuse = 3•sqrt{2}

Understand?

The three sides are 3, [3•sqrt{2}]/2 and

3•sqrt{2}.

The water diet requires one to drink two cups of water every half hour from when one gets up until one goes to bed, but otherwise allows one to eat whatever one likes. Four adult volunteers agree to test the diet. They are weighed prior to beginning the diet and after six weeks on the diet. The weights (in pounds) are

Person 1 2 3 4
Weight before the diet 180 125 240 150
Weight after six weeks 170 130 215 152

For the population of all adults, assume that the weight loss after six weeks on the diet (weight before beginning the diet minus weight after six weeks on the diet) is normally distributed with mean (µ). When testing the claim that the diet leads to weight loss after six weeks for all adults given that α=0.05, do you reject or fail to reject the Null Hypothesis, why or why not?

A textbook store sold a combined total of 354 history and sociology test books in a week. The number of history textbooks sold was two times the number of sociology textbooks sold. How many textbooks of each those were sold?

Answers

Answer: History textbooks sold = 236, Sociology textbooks sold = 118

Step-by-step explanation:

Given

- There are in total 354 books

- Let x be the number of sociology textbooks sold

- Let 2x be the number of history textbooks sold

Solve

Given

x + 2x = 354

Combine like terms

3x = 354

Divide 3 on both sides

3x / 3 = 354 / 3

x = 118

2x = 118 × 2 = 236
