In general, Volume is equal to the area of the base multiplied by the height.
Let's check the volume of each.
A.
V=area of base x height, all given, so,
B.
Volume of cone is given by,
V= one-third area of base x height, all given, so,
C.
Here, the slant height is given, not the altitude (height). The volume is not 32 nor .
D.
Rectangular solid's volume is area of base times height, all given, so,
Hence, A and D have same volume.
ANSWER: Option A and Option D have the same volume (32)
Answer:
The closest to the output when the input is approximately 12
Step-by-step explanation:
The given (x, y) coordinates are;
The line of best fit is
x, 0, 3, 6, 6, 8, 10, 11
y, -2, 7, 16, 15, 21, 28, 31
The line of best fit can be obtained from the scatter plot of the given data from where a linear pattern is apparent
A linear line of best fit is a trend line that gives an overall cumulative minimum distance of all the points from the line
The method for constructing a line of best fit includes;
1) The least Squares Method
2) The method of linear regression
3) Construction of line of best fit
a) The area method
b) The dividing method
The least squares equation is given as follows;
= a + b·x
From MS Excel, we have;
= 266.8571
= 89.42857
∴ b = 266.8571/89.42857 ≈ 2.984
From MS Excel, with the given data, we get;
= 16.57143
= 6.285714
Therefore;
a = 16.57143 - 2.984 × 6.285714 = -2.185
Therefore, we get the following regression equation;
= -2.185 + 2.9·x
Where;
x = The input
= The output
Therefore, when x = 5, we get;
= -2.185 + 2.9 × 5 = 12.315
Therefore, the closest to the output when the input is 5, y ≈ 12
