(a) and (b) looks correct
(c) Here's how my table looks like:
15 -18 324
27 -6 36
28 -5 25
34 1 1
42 9 81
52 19 361
SUM 828
(d) Take the sum of 828 and divide it by 6 to get 138. Now take the square root of 138 to get the standard deviation:
sqrt(138) ≈ 11.75
Answer:
The answer is Steps 1 and 2. Step 1: -3(x+2) = 5(x-7)
Step 2: -3x-6 = 5x-35
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
We need two points to find the slope
( -1,0) and ( 2,3)
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 3-0)/(2 - -1)
= (3-0) / ( 2+1)
= 3/3
= 1
The slope is 1
Answer:
volume of cylinder = 1232cm³
Step-by-step explanation:
from the question
volume of cylinder =?
height of the cylinder = 8cm
Base diameter of the cylinder = 14cm
to solve this problem we need to know the formula to calculate the volume of a cylinder
volume of cylinder = πr²h
or
volume of cylinder = π(d/2)²h........................... if we are given diameter and not radius.
D= 14cm
d = 14/2
d = 7cm
now,
volume of cylinder = π × (7)² × 8
volume of cylinder = 22/7 ×49 ×8
volume of cylinder = 22 × 7 × 8
volume of cylinder = 1232cm³
therefor the volume of the cylinder is equals to 1232cm³
