The amount of money Trevon had last Friday⇢$29
The total amount of money he has after cleaning the attic⇢$41
So,
The amount of money he received after cleaning the attic ⇢ Total money he has after cleaning the attic - The money he had last Friday
⇢ $41-$29⇢$12Thus ,he received $ 12 for cleaning up the attic.
Answer²↷$9.02Solution ↷The cost of the game ⇢$30.98
The amount of money she gave to the cashier ⇢$40
The amount she'll receive back⇢ the amount of money she gave to the cashier - the cost of the game
⇢$ 40 - $ 30.98⇢$ 9.02Hence , she'll receive $ 9.02 back from the cashier.
Answer:
Question 1Given:
Last Friday Trevon had $29He received money for cleaning the atticHe now has $41To calculate the money Trevon received for cleaning the attic over the weekend, we need to find the difference between the money he started with and the money he now has. To find the difference, subtract the smaller number from the bigger number:
⇒ Money Trevon received = Money he has now - money on Friday
= $41 - $29
= $12
Therefore, Trevon received $12 for cleaning the attic over the weekend.
Question 2Given:
Cost of game = $30.98Money gave the cashier = $40To calculate the change Jenny received from the cashier, we need to find the difference between the two amounts. To find the difference, subtract the cost of the game from the money Jenny gave to the cashier:
⇒ Change = money given - cost of game
= $40 - $30.98
= $9.02
Therefore, Jenny received $9.02 in change from the cashier after paying for a game that costs $30.98 with $40.

Answer:
the rule is multiply input by 25 then add 2, for example 2 x 25 = 50, 50 + 2 = 52
Step-by-step explanation:
this is because you minus 2 from the output to see the pattern from input. For example, 52 - 2 = 50 and to get from 2 to 50 you have to multiply by 25. This can be seen in the other numbers as well. Therefore the answer as a graph will be y = 25x + 2
Answer:
52 divided by 2 equal 26

Answers
The appropriate values of n and r are illustrations of permutation.
The values of n and r are 75 and 10, respectively
How to determine the appropriate values of n and r?From the question, we have the following parameters:
Albums = 6Total songs = 75Songs to arrange in a album = 10The above means that:
n = 75
r = 10
This can be interpreted as:
Arrange 10 songs from a list of 75 songs
Hence, the appropriate values of n and r are 75 and 10, respectively

1. Use the Empirical Rule to construct a 99.7% confidence interval of the proportion (round to three decimal places) of all cats that will live to be more than 11 years old.
2. What sample size should the veterinarian use to achieve a margin of error of no more than 8% for the 99.7% confidence interval using the Empirical Rule? Use p=0.5 since we do not know the exact population proportion.
Answers
Answer:
1. 0.047, 0.453
2. 343
Step-by-step explanation:
The confidence interval regarding the veterinarian will be (0.045, 0.455).
How to depict the confidence interval?Sample success = 10
Sample size = 40
Pt estimate = 10/40 = 0.25
Standard error = 0.0685
The corresponding interval is (0.045, 0.455).
The sample size that the veterinarian should use to achieve a margin of error will be:
Margin of error = 0.08
Critical Z = 3.0
Estimated proportion = 0.5
Sample size = p × (1-p) × (z/e)²
= 0.5 × (1-0.5) × (3/0.08)²
= 352

A triangle has side lengths 25, 15x and 20x. The longest side is 25. What value for x proves that this triangle is a right triangle?

To prove that this triangle is a right triangle, we need to check the side lengths using pythogoras theorem.

Refer to the graph representing the number of hybrid cars sold in January in the United States for the given years.
What is the difference between the January sales in 2008 and 2007?
The difference is _____ cars.
Answers
Answer:
First, let's find how many hybrid cars are sold during those two years.
2007 = 17,300 hybrid cars were sold
2008 = 22,600 hybrid cars were sold
Find the difference by subtracting the cars in 2007 from 2008.
22,600(2008) - 17,300(2007)
= 5,300
The difference is 5,300 cars.

You have 14 coins in your pocket that are either quarters or nickels. The total value of the coins is $2.50.
A. Write a system of two equations that represents this situation. Let q represent the number of quarters and n represent the number of nickels.
B. Solve each equation for q.
D. What is the solution to the system?
E. Verify that the answer to part D is correct using the answer to part A.
F. How many of each coin are there?
Answers
Answer:
See below.
Step-by-step explanation:
A. First equation is
q + n = 14
then we have
0.25q + 0.05n = 2.5
Multiply last equation by -20
-5q - n = -50 Now add this to the first equation
-4q + 0 = -36
B. q = -36/-4 = 9.
D Substitute for q in the first equation
9 + n = 14
n = 14 - 9 = 5.
So the solution to the system is q = 9, n = 5.
E Verify this solution by substituting in the second equation:
0.25(9) + 0.05(5)
= 2.25 + 0.25 = 2.50.
- verified.
F. 9 quarters and 5 nickels.

please help me with this graph problem. NO LINKS!!!
Answers
Step-by-step explanation:
a)
Eric runs for 4 min and walks for 8 min.
The distance covered is
4*200 + 8*80 = 800 + 640 = 1440The goal of 1600 m is not met, needs additional 160 m
b)
The equation of distance is
d = 200x + 80yc)
For d = 1600, the equation is
200x + 80y = 1600Simplified form of it
2.5x + y = 20Some combinations of x and y to make the equation right
x = 2, y = 15x = 4, y = 10x = 6, y = 5d)
See the attached graph for more combinations, where the first coordinate represents running time and the second coordinate - walking time
Answer:
Part (a)Given:
Average running speed = 200 m/minAverage walking speed = 80 m/minIf Eric runs for 4 minutes ⇒ 200 x 4 = 800 m
If Eric walks for 8 minutes ⇒ 80 x 8 = 640 m
Total distance covered = 800 + 640 = 1440 m
Therefore, he is 160 m away from his 1600 m goal.
Part (b)Let x = number of minutes Eric runs
Let y = number of minutes Eric walks
Let d = total distance Eric covers
Equation: d = 200x + 80y
Part (c)Set d = 1600, then rewrite to make y the subject:
200x + 80y = 1600
⇒ 5x + 2y = 40
⇒ 2y = 40 - 5x
⇒ y = 20 - 2.5x
Now find ordered pairs (points on the line):
x-intercept (y = 0): 20 - 2.5x = 0 ⇒ x = 8 ⇒ (8, 0)y-intercept (x = 0): 20 - 2.5(0) = 20 ⇒ (0, 20)when x = 4: 20 - 2.5(4) = 10 ⇒ (4, 10)Part (d)Plot (8, 0) (0, 20) and (4, 10) and connect with a straight line.
(see attached graph)

what is the mode median mean and range of 4,5,0,2,3,1
Answers
Answer:
Mode = none, Median = 2.5, Mean= 2.5
Step-by-step explanation:
Hope this helps! :)
Step-by-step explanation:
the mode is the data item that occurres the most often.
but in 4, 5, 0, 2, 3, 1 every number appears only once. so, the mode is 0, 1, 2, 3, 4, 5 (as special case this average number can have more than one value - like in our case here).
the median is the value in the data set that lies directly in the middle between the other values (half of them are higher, the other half is lower).
if our data set has an even number of data points, or there is no unique middle value for other reasons, then the median is the mean value of the 2 middle values.
in our case 2 and 3 are the 2 middle values, so the median is (2+3)/2 = 2.5
the mean value is directly the average value across the whole data set : the sum of all values divided by the number of values.
(0+1+2+3+4+5)/6 = 15/6 = 2.5
the range is the difference between the highest and the lowest value in the data set : 5 - 0 = 0

Answers
Answer:

Step-by-step explanation:
Let the number be a ,b
The sum of two numbers is 143
⇒ x + y = 143 -------------(I)
Their difference is 7
⇒ x - y = 7 --------------(II)
Add the equation (I) & (II) and thus y will be eliminated and we can find the value of x
(I) x + y = 143
(II) x - y = 7 {Now add}
2x = 150
x = 150 ÷ 2
x = 75
Substitue x = 75 in equaion (I)
75 + y =143

Answers
Answer:
y = 2
Step-by-step explanation:
Given equation:
[tex]2y - 5 = 5y - 11[/tex]
Subtract 5y both sides:
[tex]\implies 2y - 5 = 5y - 11[/tex]
[tex]\implies 2y - 5 - 5y = 5y - 5y - 11[/tex]
[tex]\implies -3y - 5 = -11[/tex]
Add 5 both sides:
[tex]\implies -3y - 5 = -11[/tex]
[tex]\implies -3y - 5 + 5 = -11 + 5[/tex]
[tex]\implies -3y = -6[/tex]
Multiply -1 both sides:
[tex]\implies -3y = -6[/tex]
[tex]\implies \dfrac{-3y}{-1} = \dfrac{-6}{-1}[/tex]
[tex]\implies 3y = 6[/tex]
Divide 3 both sides:
[tex]\implies 3y = 6[/tex]
[tex]\implies \dfrac{3y}{3} = \dfrac{6}{3}[/tex]
[tex]\implies \boxed{y = 2}[/tex]
