If f = {(2,5), (3, 2) (4, 6), (5, 1), (2, 2)), then f is a function.

Answer:
false
Step-by-step explanation:
f is not a function because you can see that two of the points are (2,5) and (2,2). A function can only have one corresponding y-coordinate for every x-coordinate and since this is not the case here, f is not a function.
Calculate the mean and median of: 202, 199, 223, 199, 223, 256, 301, 199
a. mean = 199, median= 212.5
b. mean = 225.25, median = 199
c. mean = 225.25, median = 212.5
d. mean = 212.5, median = 225.25
Answers
Answer:
C. mean =225.25, median= 212.5
Step-by-step explanation:
You add all the numbers and divided by the total numbers to get mean, and for get the median you need to put them in order and get the number that is between all the number it be the 202 and 223 so you divide the two number with two and it will be 212.5
Answer:
C. mean =225.25, median= 212.5
Step-by-step explanation:
Yellow trapezoid equals to ________? not 2 or 3
Answers
Answer:
The yellow trapezoid equals to 6.
Step-by-step explanation:
Assuming that two green items equals to two purple items and one yellow trapezoid, we can make the equation 5+5=2+2+x. Simplifying both sides, we get 10=4+x. If we subtract 4 from both sides and isolate x, we get that x=6.
Answer:
yellow trapezoid = 6
Step-by-step explanation:
since the green crescent equals 5, and there are two on the left side, that would equal 10, so the right side also should equal 10 too. The purple teardrops equal two, and there are two on the right side, so the total of teardrops on the right side is equal to 4. Since both sides need to equal to 10, and we only have 4, we need to find the amount of the yellow trapezoid. To do that you need to subtract 4 from 10, to get 6, which is the amount of the yellow trapezoid.

Answers
Answer:
A
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 13 and h = 4 , thus
A = [tex]\frac{1}{2}[/tex] × 13 × 4 = [tex]\frac{1}{2}[/tex] × 52 = 26 units² → A
Answer:
A, 26
Step-by-step explanation:
Since the area of a triangle is one half base times height, and we have our height as 4, and our base as 13, we get 1/2 * 13 * 4, which is equal to 13 times 2, which is 26. Thus, our answer is A, 26.

Solve for x in the triangle. Round your answer to the nearest tenth.
Answers
Answer:
8.5
Step-by-step explanation:
For this we will use trigonometry.
First lable the diagram: 13 will be the hypotenuse (H), x will be the opposite(O). Therefore, we will use sin as it is SOH.
sin Θ = [tex]\frac{O}{H}[/tex]
sin 41 = [tex]\frac{x}{13}[/tex]
x = 13 sin 41
Type this into the calculator, then you will get 8.5287677377. Round this to the nearest tenth will be 8.5.
As the question does not give any units, there will be no need to write any units after the answer.
Hope this helps

Levi would like to use a credit card to make a $3000 purchase. He is considering two credit options. The first requires a down payment of $1000 followed by monthly payments of $125. The second requires a down payment of $1300 followed by monthly payments of $110. The two options accumulate the same amount of interest and require the same number of monthly payments. What is the amount of interest for this loan?
Answers
Answer: $500
Step-by-step explanation:
Hi, since both credit options accumulate the same amount of interest:
1000+125x=1300+110x
Solving for x(number of months)
125x-110x =1300-1000
15x = 300
x =300/15
x= 20 months
Replacing x =25 in one equation:
1000+125x =
1000+125(20)=
1000+2500= $3500
Finally, we have to subtract the amount of the purchase (3000) to the result obtained:
3500-3000=$500
