Iliana’s math grade increased from 65 to 86. Fiona’s math grade increased from 70 to 80. What is the difference, rounded to the nearest whole number, between the approximate percent increases?
Answer:
18 points
Step-by-step explanation:
We first need to find the percent increase for both Iliana an Fiona.
To do so, we take the absolute value of difference (the score increase) and we compare/divide it by the original score they had.
So, for Iliana, we have a starting score of 65 and an increase of 21 (86-65).
Her percent of increase is 21/65 = 32.3%
For Fiona, she went from 70 and had a 10 points increase (80-70).
Her percent of increase is 10/70 = 14.3%
The difference between the two percent of increase is 18 points (32.3 - 14.3)
Answer with Step-by-step explanation:
Percentage increase in score is calculated by the formula:
[tex]\dfrac{New\ score-Old\ score}{Old\ score}\times 100[/tex]
Iliana’s math grade increased from 65 to 86.
Percentage increase in Iliana's score is:
[tex]\dfrac{86-65}{65}\times 100[/tex]
=[tex]\dfrac{21}{65}\times 100[/tex]
=32.31%
Fiona’s math grade increased from 70 to 80.
Percentage increase in Fiona's score is:
[tex]\dfrac{80-70}{70}\times 100[/tex]
=[tex]\dfrac{10}{70}\times 100[/tex]
=14.28%
Difference between percentage increases=32.31%-14.28%
= 18.03%
Hence, difference, rounded to the nearest whole number, between the approximate percent increases is:
18%

The original price of a DVD was 12. The price was reduced by 18% . What is the new price of the dvd.
Answer:
New price of DVD is $9.84
Answer:
The answer is C. $9.84
Step-by-step explanation:
The original price of the DVD is $12.
So, In order to calculate the price reduced by 18%
Original price - ( rate x Original price) = price reduced
18% = 18/100 = 0.18
$12 - (0.18 x $12) = price reduced
Solving
price reduced = $12 - $2.16
price reduced = $9.84
The new price of the DVD with the price reduced by 18% is $9.84

In the diagram, if EC = 8, ED = 6 and AE = 12 solve for EB.
Answer:
The length of segment EB = 4
Step-by-step explanation:
* Lets revise a fact in the circle
- When two chords intersect each other inside a circle, the
products of their segments are equal
* Now lets use this fact to solve the problem
- AB and CD are two chords in the circle intersect each other
at point E
- The segments of AB are AE and EB
- The segments of CD are CE and ED
* From the fact above
∴ AE × EB = CE × ED
∵ AE = 12 units
∵ EC = 8 units and ED = 6 units
∴ 12 × EB = 8 × 6
∴ 12 EB = 48 ⇒ divide both sides by 12
∴ EB = 4
* The length of segment EB = 4
Answer:
The length of segment EB = 4 units
Step-by-step explanation:
From the figure we can see a circle with two chords intersects each other.
The products of segments of chords are equal
To find the length of EB
we have EC = 8, ED = 6 and AE = 12
From the figure we can write,
AE * EB = EC * ED
EB = (EC * ED)/AE
= (8 * 6)/12 = 4 units
Therefore the correct answer is EB = 4 units

The perimeter of a rectangle is 44. The length is 5 less than double the width. Find the dimensions
Length: 2w - 5
Width: w
2(2w - 5) + 2w = 44
Distribute:
4w - 10 + 2w = 44
Combine like terms:
6w - 10 = 44
Move 10 to the other side:
6w = 54
Divide by 6:
w = 9, which is the width. That means that 13 is the length.
To find the dimensions of the rectangle, we can set up a system of equations and solve for the width and length. By using the formula for the perimeter of a rectangle, we can find the values of the dimensions.
Explanation:To solve this problem, we can set up a system of equations based on the given information. Let's assume that the width of the rectangle is 'w', and since the length is 5 less than double the width, we can express the length as '2w - 5'. The perimeter of a rectangle is given by the formula 2(length + width), so we can use this formula to set up an equation:
2(2w - 5 + w) = 44
Simplifying this equation, we get 6w - 10 = 44. Solving for 'w', we find w = 9. Substituting this value back into the expression for the length, we find the length is 13.
Therefore, the dimensions of the rectangle are width = 9 and length = 13.

If y = 3x – 4 and the domain is { -3, -1, 4}, find the range. When the domain is -3, the range is ______. Show your work to find the range.
The answer is:
When the domain is -3, the range is -13.
Why?To solve the problem, we need to remember that the domain is also known as the input of the function, and the range of the function is also known as the output of the function.
We are given the inputs and we are asked to calculate the output of the function at -3, so, evaluating -3 into the function, we have:
[tex]y=3x-4\\f(x)=3x-4\\f(-3)=3*(-3)-4=-9-4=-13\\[/tex]
Hence, we have that when the domain is -3, the range is -13.

A book store is having a 30% off sale. Dairy of the wimpy kid books are now $6.30 each. What was the original price of the books.
Answer:
100% - 30% = 70%
70% = 0.7
6.30 / 0.7 = $9
answer: original price of the books were $9
Answer:
original price of the books was $ 9.
Step-by-step explanation:
Given: A book store is having a 30% off sale. Dairy of the wimpy kid books are now $6.30 each.
To find : What was the original price of the books.
Solution : We have given that discount = 30%
Cost percent 100% - 30% = 70%
Cost of each book after discount = $6.30.
Let us consider the original price of book = x
x * 70% = $6.30.
x * [tex]\frac{70}{100}[/tex] = $6.30.
On multiplying by 100 both sides
x *70 = 6.30 * 100.
x * 70 = 630.
On dividing both sides by 70
x = [tex]\frac{630}{70}[/tex].
x = $ 9 .
Therefore, original price of the books was $ 9.

I am pretty sure your test score has to be an 86.
Answer:
100
Step-by-step explanation:
Let the unknown score be x.
To find the average, you add all the scores and divide by the number of tests. Let's add all the scores including x:
89 + 95 + 76 + x = 260 + x = x + 260
All 4 scores, including the unknown one, add to x + 260.
To find the average, you divide the sum of the scores by the number of grades, which is 4 in this case.
The average is
(x + 260)/4
You want the average to be 90, so set the average equal to 90 and solve for x.
(x + 260)/4 = 90
Multiply both sides by 4.
x + 260 = 360
Subtract 260 from both sides.
x = 100
You must get a 100 on the next test.

There are two outliers, indicating very few books were rented out on those two days.
There are two outliers, indicating an abnormally large number of books were rented out on those two days.
There is one outlier, indicating an abnormally large number of books were rented out on that day.
Answer:
B
Step-by-step explanation:
There are two outliers, indicating very few books were rented out on those two days.
outlier: a person or thing situated away or detached from the main body or system. Since there are only two smaller numbers those are considered the outliers.
There are two outliers in this data set, indicating very few books were rented out on those two days. These outliers, 10 and 9, are significantly lower than the other data points and can skew the mean and standard deviation.
Explanation:To analyze outliers in a data set, we first need to understand that an outlier is a data point that is significantly different from the other points. In this data set, most of the numbers are close to 90, while two numbers stand out, 10 and 9. These numbers are significantly lower than other values.
From this, we can conclude that:
There are two outliers, indicating that very few books were rented out on those two days.
It's important to also note that the presence of outliers can often have a significant effect on the mean and standard deviation of the data set. So, in this case, the mean number of books rented per day and the variability (standard deviation) might be skewed by these outliers.

Answer:
DNE.
Step-by-step explanation:
8x - 2y = 1 ---------------------(1)
-4x+ y = 3----------------------(2)
Multiply (2) by 2
-8x +2y = 6 -----------------(3)
Add (1) to (3)
8x - 2y + (- 8x + 2y) = 1+6
8x - 2y - 8x +2y = 7
But all the terms in LHS cancel out, leaving 0.
So you get 0=7, which is not valid.
Therefore no solution exists. DNE
