Answer:
$16,725.21
Step-by-step explanation:
To get the cost of the copper used for the sculpture, we must first determine the volume of the object which is given as a cone
Recall that the volume V of a cone
= 1/3Pir^2h
where r is the base radius and h is the height
Given that the sculpture is 67 inches tall, and its base has a radius of 15 inches, the volume of the sculpture
= 1/3 * 3.14 * 15^2 * 67
= 15,778.5 cubic inch
If copper costs 1.06$ per cubic inch, then the cost of the copper for the sculpture
= 15,778.5 * 1.06
= $16,725.21
First add all the numbers in the data:
15.8 + 14.9 + 16.7 + 17.6 + 13.4 = 78.4
Divide by how many numbers are in the data set there is 5 so:
78.4 ÷ 5 = 15.7
The mean is 15.7
Answer:
y=0
Step-by-step explanation:
Reorder the terms:
2 + -1(2 + y) = 3y
2 + (2 * -1 + y * -1) = 3y
2 + (-2 + -1y) = 3y
Combine like terms: 2 + -2 = 0
0 + -1y = 3y
-1y = 3y
Solving
-1y = 3y
Add '-3y' to each side of the equation.
-1y + -3y = 3y + -3y
Combine like terms: -1y + -3y = -4y
-4y = 3y + -3y
Combine like terms: 3y + -3y = 0
-4y = 0
Divide each side by '-4'.
y = 0

Answer:
see below
Step-by-step explanation:
The formula for slope is
m = (y2-y1)/(x2-x1)
The person who tried to solve the problem did
Subtracted the x's over the y's instead of the y's over the x's
It should be (0-3)/(-4 -2)
-3/-6
