Step-by-step explanation:
if x=2 and y=2 and radius=2
(x_2)2. +(y_2)2 =2x2
x2 -4x+4 +y2 -4y+4=4
x2 +y2 -4x- 4y +8-4=0
x2 +y2 -4x -4y +4=0
Answer:
a) 83
b) mean and mode are both 83
Step-by-step explanation:
a) mean is the average. so add all the numbers and divide by the number of numbers.
<u>88 + 73 + 81 + 83 + 79 + 94 + T</u> = 83
7
b) median - put the numbers in numerical order, smallest to largest, what is the middle number (4th number) 73, 79, 81, 83, 83, 88, 94
mode - which number shows up most frequently?
Let's say that BC is x, so that AB is 4x, and AE = y.
The shaded area then is represented by 4xy/2 = 2xy.
The total area is represented by (4x+x)*y = 5xy.
The fraction of these is 2xy/5xy = 2/5.
