Answer:
D
Step-by-step explanation:
A is not true because from the graph, they make less money at $13 compared to $10 even though 13 > 10. B isn't true either because when the app price is more than $7 the profit decreases, not increases. D is true because the y-coordinate of the vertex (which is the maximum in this case) is about 40 million, and if we know the maximum already we know that C is false because 40 ≠ 7.

Answers
The data is already sorted for us. If it wasn't, then you would have to write the values from smallest to largest.
The median is the middle most value 9 (in slot 4)
The median separates the data into two halves, which I'll call the lower and upper half
lower half = {4,6,8}
upper half = {13,21,31}
The median of the lower half is 6, and this is the value of Q1.
The median of the upper half is 21. This is the value of Q3
Grady marks down some $2.49 pens to $1.99 for a week and then marks them back up to $2.49. Find the percent of increase and the percent of decrease to the nearest tenth. Are the percent of change the same for both price changes? If not, which is a greater change?
Please, need answer in 5 minutes
Answers
The percent decrease is found by using the formula (original price - new price)/(original price). The percent decrease is then (2.49 - 1.99)/2.49 = 0.20 = 20%. A percent increase is found by using the formula (new price - original price)/(original price). The percent increase is then (2.49 - 1.99)/1.99 = 0.25 = 25%. The percents of change are not the same. The percent increase is greater.
Answer:
2.49-1.99= 0.5
0.5 divided by2.49 times 100 is about 20% decrease
1.99-2.49+0.5 also so it is also a 25 percent increase
Step-by-step explanation:
If sin 30º = cos(3x), then x=_
Answers
Answer:
x = 20º
Step-by-step explanation:
we know that sin x = cos(90-x)
Hence
sin 30º = cos(90 - 30)º
sin 30º = cos 60º
hence sin 30º can be also written as cos 60º
Also, as given
sin 30º = cos(3x)
therefore
cos 60º = cos(3x)
as we have cos on both side then angle for both side will be same
60º = 3x
=> 60º / 3 = x
=> x = 20º
Then x = 20º is answer.

The vertices of a rectangle are A(-2, 4), B(-2,6), C(3,6), and D(3, 4). Which expression
shows how to find the length of the diagonal?
Answers
Answer:
Third option correct
Step-by-step explanation:
The diagonal is the distance between 2 of the vertices, and to end.
So the option we shall choose will contain 2 of the vertices in a distance between points equation.
Mathematically, the distance between two points is given by;
D = √(x2-x1)^2 + (y2-y1)^2
The correct option is the third option.
This is because it takes into consideration two of the vertices which are points A and point C

If AB = 3x + 5, BC = 2x + 8, and AC = 88, what is the value of x?
Answers
Answer:
x = 15
Step-by-step explanation:
AB + BC = AB
3x+5 + 2x+8 = 88
Combine like terms
5x +13 = 88
Subtract 13 from each side
5x+13-13 = 88-13
5x = 75
Divide each side by 5
5x/5 = 75/5
x = 15
Answer:
15
Step-by-step explanation:
AB + BC = AB
3x + 5 + 2x + 8 = 88
5x + 13 = 88
5x = 88 - 13
= 75/5
= 15

-6(4 + 5v) - 3 = -57 solve for V
Answers
-6(4 + 5v) - 3 = -57
Use distributive properties
-24 -30V -3 = -57
Combine like terms
-27 -30v = -57
Add 27 to both sides
-30v = -30
Divide both sides by -30
V=1
Answer:
v = 1
Step-by-step explanation:
-6(4 + 5v) - 3 = -57
Add 3 to each side
-6(4 + 5v) - 3+3 = -57+3
-6(4 + 5v) = -54
Divide by -6 on each side
-6(4 + 5v) / -6 = -54/-6
4+5v = 9
Subtract 4 from each side
4+5v-4 = 9-4
5v = 5
Divide each side by 5
5v/5 = 5/5
v =1

A)the set of integers
B)the set of natural numbers
C)the set of rational numbers
D)none of the above
Answers
Answer:
A) the set of integers is commutative under operation '-'
The commutative property holds for Addition and Multiplication, but not for subtraction and division.
So, option (D) is correct.
The commutative property states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer.
The commutative property holds for Addition and Multiplication,
Example, [tex]2+4=4+2[/tex]
[tex]3*2=2*3[/tex]
The commutative property does not holds for subtraction and division.

Step-by-step explanation:
Interpreting Box Plots
A box plot is used to present the 5-Number summary of a set of data.
The 5-Number summary consists of the following in their order of appearance on the box plot.
Minimum ValueFirst Quartile, [tex]Q_1[/tex]Median, [tex]Q_2[/tex]Third Quartile, [tex]Q_3[/tex]Maximum ValueIn the box plot, the following rules applies
The whisker starts from the minimum value and ends at the first quartile.The box starts at the first quartile and ends at the third quartile. There is a vertical line inside the box which shows the median. The end whisker starts at the third quartile and ends at the maximum value.Using these, we interpret the given box plot
A left whisker extends from 1 to 6.
Minimum Value=1First Quartile =6The box extends from 6 to 16 and is divided into 2 parts by a vertical line segment at 12.
Median=12Thrid Quartile=16The right whisker extends from 16 to 19.
Maximum Value =19Therefore any set of data that satisfies the 5-Number summary: 1,6,12,16 and 19 can be represented with the box plot.
