Answer:
(15/31) ?
Step-by-step explanation:
|-15| = 15
15+15+1 (for 0) = 31
1 through 15 are positive, so 15 of the 31 could be positive, or 15/31
Sorry, could be wrong, but I think it's right

Answer:
jacket 80
shoes 32 and 16
shirt 9 , 8.04, 4.08
Step-by-step explanation:
you need to multiply the original cost by the percentage off and then subtract from the original
example
Jacket is originally priced at $120 it is on sale for 1/3 off which means that if you divide 120 by 3 you will get 40. but you would have to subtract the 40 from 120 giving you 80

The histogram shows the scores on a recent science test.
Using the histogram, select all of the true statements that describe the data.
(Pls help the correct answer gets brainiest)
Also, remember to look at all the pages.
And their is more than one answer
Answer:
Answer In Explanation
Step-by-step explanation:
O More Than Half Of The Students Scored 81 Or Better
O The Same Number Of Students Scored Between 81 And 90 On The Test As Scored Between 61 And 80
-The Last One Is Confusing Because It Doesn't Say 71-80
Options (B) and (D) are true statements that describe the data in the histogram are the correct answers.
What is a histogram?A histogram is a visual way to display frequency data using bars. It is a chart that shows frequencies for intervals of values of a metric variable. It is a display of statistical information that uses rectangles to show the frequency of data items in successive numerical intervals of equal size.
For the given situation,
The histogram shows the scores on a recent science test.
We need to check the options, which statements describe the data.
Option A: Only two students scored less than 71 on the test.
There are four students scored less than 71.
So option A is false.
Option B: More than half of the students scored 81 or better on the test.
Students scored more than 81 = [tex]16+8[/tex]
⇒ [tex]24[/tex]
Total number of students = [tex]40[/tex]
Half of the students = [tex]\frac{40}{2}[/tex]
⇒ [tex]20[/tex]
Thus, [tex]24 > 20[/tex]
So option B is true.
Option C: More students scored between 91 and 100 on the test than scored between 71 and 80.
Students scored between 91 and 100 = [tex]8[/tex]
Students scored between 71 and 80 = 12
⇒ [tex]8 < 12[/tex]
So option C is false.
Option D: The same number of students scored between 81 and 90 on the test as scored between 61 and 80.
Students scored between 81 and 90 = [tex]16[/tex]
Students scored between 61 and 80 = [tex]4+12[/tex]
⇒ [tex]16[/tex]
Thus, [tex]16=16[/tex]
So, option D is true.
Option E: There were 12 students who scored 80 on the test.
The score range is between 71 to 80. So we could not predict the number of students who score 81.
So option E is false.
Hence we can conclude that options (B) and (D) are true statements that describe the data in the histogram are the correct answers.

-4(x-1)=-3x+13-9-x
PLS SOLVE IT STEP BY STEP
Answer:
x can be any real number.
Step-by-step explanation:
- 4 (x - 1) = - 3x + 13 - 9 - x
The easiest approach to solving this problem is to simplify each side. Start by focusing on the left side, distribute the term outside of the parenthesis, multiply every term inside the parenthsis by the term outside of it,
- 4 ( x - 1 ) = - 3x + 13 - 9 - x
Distribute,
(-4)(x) + (-4)(-1) = - 3x + 13 - 9 - x
Simplify,
-4x + 4 = - 3x + 13 - 9 - x
Simplify the right side of the equation, combine like terms,
-4x + 4 = - 3x + 13 - 9 - x
Rearrage,
-4x + 4 = -3x - x + 13 - 9
Simplify,
-4x + 4 = -4x + 4
At this point, one should use inverse operations to solve the problem, but the given equation is an identity, meaning that any real value can be substituted into the parameter (x), and the equation will yield a true result. Thus, (x) equals all real numbers.

Two dams, when opened, release water at different rates. The following functions represent the amounts of water the dams release over t minutes:
Dam A
f(t) = 5t – 7t – 1
Dam B
g(t) = 3t 2 + 4t + 9
Which function represents the difference in the amounts of water released, h(t) = f(t) – g(t)?
h(t) = 3t 2 – 5t + 11t + 10
h(t) = 2t 2 – 11t – 10
h(t) = 5t – 3t 2 – 3t + 8

Angle PQR and angle TQV are vertical angles. The measures of the two angles have a sum of 100o. Write and solve an equation to find x, the measures of angle TQV.
Answer:
I'm not certain what the sum is, so I will teach you how to solve.
Step-by-step explanation:
As the question states, angle PQR and TQV are vertical angles, so they have to be the same measure. Just divide the sum by 2 and you get the answer.
If there were more context, I would totally edit my answer!

Answer:
Step-by-step explanation:
Min. = 7
Max. = 13
Median = 10
Q1 = 8
Q3 = 12
IQR = 4
Step-by-step explanation:
Sorting it in order: 7, 8, 9, 10, 11, 12, 13
To find the median: Look for the middle number. In this case, the middle number is 10.
To find the 1st quartile: The first quartile is the median of the first half of the data. So, the first half of the data is 7, 8, 9. The median is 8.
To find the 3rd quartile: The third quartile is like the 1st quartile, but it's on the other end. So, it contains 11, 12, 13. The median of that is 12.
To find the maximum: The maximum is the largest number in the data set. So, in this case, it is 13.
To find the minimum: The minimum is the smallest number in the data set. In this case, it is 7.
Data in all: median: 10 1st Quartile: 8 3rd Quartile: 12 Min: 7 Max: 13

I don't understand this
Answer:
If you use the area formula it should be really simple.
Step-by-step explanation:
Have you been taught base x height?
Answer:
To find the area, you use a specific formula for the shape.
For the squares and rectangles, multiply the length by the width.
For a triangle do base times height divided by 2.
I would suggest asking your teacher for help with the formula.
