Answer:
The center is (0,0) and the radius is 4
Step-by-step explanation:
x^2+y^2=16.
The equation of a circle can be written in the form
(x-h)^2+(y-k)^2=r^2 where ( h,k) is the center and r is the radius
(x-0)^2+(y-0)^2=4^2
The center is (0,0) and the radius is 4
Carter paid $200 for the bike.
Step-by-step explanation:
Given,
Current value of bike = $90
This represent 45% of the original amount Carter paid for bike.
Let,
x represent the original amount of bike.
45% of x = 90

Dividing both sides by 0.45

Carter paid $200 for the bike.

To find the median you list out all the numbers and find the middle.
80, 90, 100
With angie getting 75, it goes from "80, 90, 100" to "75, 80, 90, 100"
This changes the median from 90 to 85.
Mean is the average of all the numbers. The average of the first set of numbers (Found by adding all of the numbers up and dividing by the amount of numbers present) is 90.
The mean of the second set is 86.25
The answer would be A, both the mean and median will decrease.
Answer:
left, right
Step-by-step explanation:
If you use the < or ≤ symbol to compare the numbers, their left-right order is the same as on the number line. Here, we would write the ordering as ...
-21 < -20 < -19
So, we see that ...
-21 is <em>left</em> of -20 on the number line
-19 is <em>right</em> of -20 on the number line
