The mean is the average. To find it, you add all of the numbers together.
2 + 8.7 + 11.9 + 3.3 + 4.2 + 2.2 + 13.4 = 45.7
Now you divide the total by the amount of numbers you added. Because you added 7 numbers, you divide 45.7 by 7.
45.7 ÷ 7 = 6.52 (This is the mean.)
To find the median you have to put all of the numbers in order of least to greatest.
2 2.2 3.3 4.2 8.7 11.9 13.4
The median is the number in the very middle. In this case, it is 4.2.
Answer:
25+144 = 169
Step-by-step explanation:
Step-by-step explanation:
x² + x - 2 = 0
x² + 2x - x - 2 = 0
x(x + 2) - 1(x + 2) = 0
(x + 2)(x - 1) = 0
x + 2 = 0 and x - 1 = 0
x = -2 and x = 1
So, f(x) has no solution if x = -2 or 1
Domain = {x | x ≠ 2 and x ≠ 1}
Answer:
<em>5,086.8cm³</em>
Step-by-step explanation:
Given the following
radius of the cylinder r = 9cm
Height of the cylinder h = 20cm
Volume of a cylinder = πr²h
Substitute:
V = π(9)²(20)
V= 3.14 * 81 * 20
<em>V = 5,086.8cm³</em>
<em>Hence the volume of the cylinder is 5,086.8cm³</em>
