Answer:
He will pay $922 Eve month where
$238.6667 is the interest in the payment
Step-by-step explanation:
Eric Shotwell borrows $24,600 from a certain bank. The interest charge amounts to $8,592 to be paid back in 36 months monthly.
Total money to be paid back
= 24600+8592
Total money to be paid back
= $33192
Now for each month in 36 months, a certain amount must be paid
That amount= 33192/36
= $922
But if the interest wasn't added
He'll pay= 24600/36
=$683.333
So the interest amount in the payment every month= 922-683.333.
= $238.6667
He will pay $922 Eve month where
$238.6667 is the interest in the payment
The calculation is as follows:Total money to be paid back
= 24600+8592
= $33192
Now for each month in 36 months, a certain amount must be paid
That amount= [tex]33192\div36[/tex]
= $922
Now in the case when the interest wasn't added
He'll pay= [tex]24600\div 36[/tex]
=$683.333
So the interest amount in the payment every month is
= 922-683.333.
= $238.6667

List the smallest three values in the set below. {x | x ∈ N and 20 < x}
Answer:
21, 22 and 23Step-by-step explanation:
Given the set A = {x | x ∈ N and 20 < x} , from the set it can be seen that the element of the set are natural numbers where 20< x.
If 20< x
reciprocating both sides will change the sense of the inequality
1/20>1/x
cross multiply
x > 20
This means that the values of x are values grater than 20.
The smallest three values will be the smallest three natural numbers greater than 20 and they are 21, 22 and 23. Note that natural numbers are whole numbers.

Ellen has $75 in her savings account she deposits 25 every week her father also deposit 35 into the account every time Ellen most salon
Answer:
She have 345$ in her account.
Step-by-step explanation:
Given that,
Ellen has $75 in her savings account she deposits 25 every week her father also deposit 35 into the account every time Ellen most salon
Suppose, her savings account balance can be shown with the following expression:
75 + 25w + 35m
If Ellen saves for 8 weeks and most the salon 2 times, how much will she have in her account.
We know that,
When the numbers appear with variables it called coefficients.
When the numbers appear without variables it called constant.
Alphabets in an expression are called variables.
According to question,
25 and 35 are the coefficients and the number 75 appear without variables.
We need to calculate the balance in her account
Using expression
[tex] 75 + 25w + 35m [/tex]
Put the value in the expression
[tex]75+25\times8+35\times2[/tex]
[tex]=345$[/tex]

Solving these Quadratics for x using factoring 2x^2+5x = 3
Answer:
x = 1/2 ; x = -3
Step-by-step explanation:
To solve this problem, we first need the quadratic to be set equal to x. Then, we can use factoring to solve for the values of x.
2x^2 + 5x = 3
2x^2 + 5x + -3 = 3 + -3
2x^2 + 5x + -3 = 0
Note that the first term's coefficient is 2. This factors into 1 and 2.
Note that the third term's coefficient is -3. This factors into 3 and -1.
From here, we will simply create the binomial factors for the quadratic.
(2x - 1) (x + 3) = 0
2x - 1 = 0 ; x + 3 = 0
2x - 1 + 1 = 0 + 1 ; x + 3 + -3 = 0 + -3
2x = 1 ; x = -3
2x * 1/2 = 1 * 1/2 ; x = -3
x = 1/2 ; x = -3
So our solutions for this quadratic equation are x = 1/2 or x = -3.
Cheers.
Solution:
2x²+5x=3
Using Factorisation method,

Answer:
39 meters
Step-by-step explanation:
We know the bottom distance ( 20-13) = 7
And we know the height 15-0 =15
We can use the Pythagorean theorem to find the hypotenuse
a^2 + b^2 = c^2
7^2 + 15^2 = c^2
49+225 = c^2
274 = c^2
Taking the square root of each side
sqrt(274) = c
We want the perimeter
a+b+c
7+15+sqrt(274)
22+sqrt(274)
22+16.55294536
38.55294536
Rounding to the nearest meter
39 meters
Answer:
[tex]\huge \boxed{\mathrm{39 \ meters}}[/tex]
Step-by-step explanation:
The perimeter of the right triangle is required.
The base of the triangle is 7 units.
The height of the triangle is 15 units.
The hypotenuse can be found through Pythagorean theorem.
a² + b² = c²
7² + 15² = c²
49 + 225 = c²
274 = c²
c = [tex]\sqrt{274}[/tex]
Adding all the three sides of the right triangle to get the perimeter.
P = a + b + c
P = 7 + 15 + [tex]\sqrt{274}[/tex]
P = 38.552945...
The perimeter of the right triangle is 39 meters rounded to nearest meter.

D=xlx is a whole number)
E = {xlx is a perfect square between 1 and 9)
F={xlx is an even number greater than or equal to 2 and less than 9)
Which of the following is an element of D n (E n F)?
16
3
6
4
Answer:
Option (4)
Step-by-step explanation:
D = {x| x is a whole number}
D = {1, 2, 3, 4..........}
E = {x | x is a perfect square between 1 and 9}
E = {4}
F = {x | x is an even number greater than 2 and less than 9}
F = {2, 4, 6, 8}
(E ∩ F) = Set of common numbers of E and F
= {4}
D ∩ (E ∩ F} = Set of common numbers in the sets of D and (E ∩ F)
= {4}
Therefore, Option (4) will be the answer.
There are 12 peaches and 8 bananas in a fruit basket. You get a snack for yourself and three of your friends by choosing of the pieces of fruit at random. 1)What is the probability that all 4 are peaches! 2)what is the probability that all 4 are bananas?
Answer:
10.2% chance
Step-by-step explanation:
There are 12 peaches and 8 bananas for a total of 20 pieces of fruit.
So we can write it:
[tex]\frac{12}{20} * \frac{11}{19} * \frac{10}{18} * \frac{9}{17}[/tex] = [tex]\frac{11880}{116,280}[/tex] = .102 or 10.2% chance
For ease multiply all numerators (top numbers) together, then multiply the denominators (bottom numbers) together, and then divide.
12 * 11 * 10 * 9 = 11880
20 * 19 * 18 * 17 = 116,280
We start with 12 peaches and 20 total fruit, as we select a peach the number of peaches and total fruit goes down by one. We do this 4 times because you draw 4 fruits. If you select 1 fruit your chances of it being a peach are 12/20, each time you select a fruit the chances of it being a peach go down because you have 1 less total fruit, and 1 less peach. This is why you multiply each probability together.
ΔDEF is formed by lines tangent to the circle, where = 13.7, = 9, and = 14. Determine the perimeter of ΔDEF.
Question 1 options:
1)
68.4
2)
73.4
3)
73.7
4)
73.1
Answer:
Option (2)
Step-by-step explanation:
To solve this question we will use the property of tangents drawn to a circle.
"Tangents drawn from an external point to a circle are equal in length"
From the figure attached,
In ΔDEF,
DA = DC = 14 units [Equal tangents]
EA = EB = 13.7 units [Equal tangents]
FB = FC = 9 units [Equal tangents]
Therefore, DE = DA + AE = 14 + 13.7 = 27.7 units
EF = EB + BF = 13.7 + 9 = 22.7 units
DF = DC + FC = 14 + 9 = 23 units
Perimeter of ΔDEF = DE + EF + DF
= 27.7 + 22.7 + 23
= 73.4 units
Option (2) will be the answer.

Answer:
1. The mean of the data summarized in the given frequency distribution is 51.81 degrees
2. Comparing the computed mean (51.81 degrees) to the actual mean(56.6) degrees, the computed mean is lesser than the actual mean.
Step-by-step explanation:
1) We are given a Frequency distribution.
Mean of a frequency distribution = Fx/F
Where
Fx = Frequency × midpoint
Low Temperature (◦F) Frequency
40−44 2
45−49 7
50−54 9
55−59 6
60−64 2
F =Total Frequency
= 2 + 7 + 9 + 6 + 2
= 26
a)For low temperature 40 - 44
Frequency = 2
Midpoint (x) = 40 +44/2 = 42
Fx =42 × 2 = 84
b) For low temperature 45 - 49
Frequency = 2
Midpoint (x) = 45+49/2 = 47
Fx =47 × 7 = 329
For low temperature 50 - 54
Frequency = 2
Midpoint (x) = 50 + 54/2 = 52
Fx =52 × 9 = 468
For low temperature 55 - 59
Frequency = 6
Midpoint (x) = 55 + 59/2 = 57
Fx =57 × 6 = 342
For low temperature 60 - 64
Frequency = 2
Midpoint (x) = 60 +64/2 = 62
Fx =62 × 2 = 124
Total Fx =84 + 329 + 468 + 342 + 124
= 1347
Mean =Total Fx/ Total Frequency
= 1347/26
= 51.807692308
Approximately = 51.81 degrees
Therefore, mean of the data summarized in the given frequency distribution is 51.81 degrees
2. Comparing the computed mean (51.81 degrees) to the actual mean(56.6) degrees, the computed mean is lesser than the actual mean.

How many ways can the letters of the word MINUTES be arranged in a row if M and I must remain next to each other as either MI or IM
Answer:
1440 combinations ways
Step-by-step explanation:
We know that the total arrangements will be
6!= 720 because its a 6letter word
So if we take MI to be a one letter word
Same for IM
which will Also be 6!= 720
SO TOTAL possible combination will be 720+720= 1440
Answer:
1440 ways
Step-by-step explanation:
First, we must consider how many letters are in the word "minutes"
7.
This means that the word "minutes" can be arranged in 7! ways, or simply put in 5040 ways.
But then, we're interested in how many ways it can be arranged with I and M besides each other.
In how many ways can the word be arranged with the letters "MI" together
We would have, "MI, N, U, T, E, S" which happens to be 6!, or say 720 ways.
In how many ways can the word be arranged with the letters "IM" together
We would have, "IM, N, U, T, E, S"
which happens to be 6! or again, 720 ways.
Then, the number of ways it can be arranged with "IM" or "MI" together is
720 + 720, and therefore 1440 ways

The purchase price of an iPad is $650. What is the total price if the sales tax rate is 8% and there is a 15% off sale today?
Answer:
Original cost + tax = Total cost
650+0.08(650) =
650+52 = $702
Answer:
$599.72
Step-by-step explanation:
8% of 650 is $52 so you add that to $650 which comes up to $702, then you find 15% of the total price, which is $105.30 you subtract that from the total price and you come up with $599.72.

"When comparing the means of two independent samples, the population standard deviations will almost always be"
Answer: Check this answer!
Step-by-step explanation:
The comparison of two independent population means is very common and provides a way to test the hypothesis that the two groups differ from each other. Is the night shift less productive than the day shift, are the rates of return from fixed asset investments different from those from common stock investments, and so on? An observed difference between two sample means depends on both the means and the sample standard deviations. Very different means can occur by chance if there is great variation among the individual samples. The test statistic will have to account for this fact. The test comparing two independent population means with unknown and possibly unequal population standard deviations is called the Aspin-Welch t-test.
In simple terms, The population standard deviation is a parameter, which is a fixed value calculated from every individual in the population. A sample standard deviation is a statistic. This means that it is calculated from only some of the individuals in a population. Since the sample standard deviation depends upon the sample, it has greater variability. Thus the standard deviation of the sample is greater than that of the population
Because: reason:
Since the sample standard deviation depends upon the sample, it has greater variability. Thus the standard deviation of the sample is greater than that of the population.

Write the slope-intercept form of the line passing through (–8, –5) and (4, 4).
Answer:
[tex]\Huge \boxed{y=\frac{3}{4} x+1}[/tex]
[tex]\rule[225]{225}{2}[/tex]
Step-by-step explanation:
We can find the slope through two points.
m = (y2 - y1)/(x2 - x1)
m = (4 - -5)/(4 - -8)
m = 9/12 = 3/4
The slope of the line is 3/4.
Slope-intercept form of a line is y=mx+b. Where m is the slope and b is the y-intercept.
y = 3/4x + b
A point on the line is (4, 4). x = 4 and y =4.
4 = 3/4(4) + b
4 = 3 + b
b = 1
The y-intercept is 1.
[tex]\rule[225]{225}{2}[/tex]
Answer:
[tex]\huge\boxed{y = \frac{3}{4}x+1}[/tex]
Step-by-step explanation:
Finding the slope (m) first:
Given the coordinates (-8 , -5) and ( 4 , 4 )
Slope = [tex]\sf \frac{Rise}{Run}[/tex]
Slope = [tex]\sf \frac{y2-y1}{x2-x1}[/tex]
Slope = [tex]\frac{4 + 8}{4+5}[/tex]
Slope = [tex]\frac{12}{9}[/tex]
Slope = m = [tex]\frac{3}{4}[/tex]
Finding y - intercept (b) :
Taking a coordinate say (4,4)
And putting it in slope intercept form along with b
y = mx+b
Where y = 4 , m = 3/4 and x = 4
4 = (3/4)(4) + b
4 = 3+b
4-3 = b
1 = b
So,
b = 1
Putting m and b now in slope-intercept equation:
y = mx+b
[tex]y = \frac{3}{4}x+1[/tex]

The length of a new rectangular playing field is 4 yards longer than quadruple the width. If the perimeter of the rectangular playing field is 488 yards, what are its dimensions?
Answer:
w = 48
w = 196
Step-by-step explanation:
Width = w
Length = l = 4 + 4w
Use the values for length and width above along with the given value for perimeter in the formula for perimeter.
P = 2l + 2w
488 = 2(4 + 4w) + 2w
488 = 8 + 8w + 2w
488 = 8 + 10w
488 - 8 = (8 + 10w) - 8
480 = 10w
(480)/10 = (10w)/10
48 = w
w = 48
The width is 48 yards. Use this value to solve for length.
l = 4 + 4w
l = 4 + 4(48)
l = 4 + 192
l = 196
The length is 196 yards.

h is the height
From the question
Area = 21 m²
The statement
The height of a triangle is 8 m more than the length of the base is written as
h = 8 + b
Make b the subject
That's
b = h - 8
Substitute the expression into the above formula and solve for the height
That's
[tex]21 = \frac{1}{2} (h - 8)h[/tex]
Multiply through by 2
h² - 8h = 48
h² - 8h - 48 = 0
(h + 4)(h - 12) = 0
h + 4 = 0 h - 12 = 0
h = - 4 h = 12
Since the height cannot be a negative number we have the final answer as
height = 12 cmHope this helps you
