To estimate the volume of the chord of wood, since the wood exists cut into equal lengths and stacked evenly in a rack then we can use a cylinder as a model.
<h3>What is a cylinder?</h3>
In mathematics, a cylinder exists as a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance. These bases exist normally circular (like a circle) and the center of the two bases exists joined by a line segment, which exists named the axis.
A cylinder exists as a closed solid that contains two parallel circular bases joined by a curved surface.
To calculate the volume of the chord of wood, since the wood exists cut into equal lengths and stacked evenly in a rack then we can use a cylinder as a model.

Answer:
So then the best answer for this case would be:
C. 2.78
Step-by-step explanation:
For this case we have the following probabability distribution function given:
Score P(X)
A= 4.0 0.2
B= 3.0 0.5
C= 2.0 0.2
D= 1.0 0.08
F= 0.0 0.02
______________
Total 1.00
The expected value of a random variable X is the n-th moment about zero of a probability density function f(x) if X is continuous, or the weighted average for a discrete probability distribution, if X is discrete.
If we use the definition of expected value given by:
And if we replace the values that we have we got:
So then the best answer for this case would be:
C. 2.78
Answer:
Step-by-step explanation:
Given that,
The area of the base = 13.2 cm²
The height of the pyramid = 13.7 cm
We need to find the volume of this pyramid. The formula can be given by :
Put all the values,
So, the volume of the pyramid is equal to .
Answer:
Step by step explanation:
We have been given a number 75 and we are supposed to rewrite it using a different way. Since the given number has been written in standard notation, we can write it using scientific notation.
We know that we can write a standard number in scientific notation by moving the decimal point to the left or right and making corresponding changes to the exponent of 10. In this case, we will move the decimal point to the left by one place and raise the exponent of 10 by 1. Therefore, we get the required number in a different notation (scientific notation) as .
Answer:
217 ft^2
Step-by-step explanation:
Area for triangle is 1/2 bh
The b is the base and h is the height
For the base, 4 is included but we need to find the other piece for the base. so…
8 + 9 = 11 + ?
17 = 11 + ?
? = 17 - 11
? = 6
Then add 6 and 4
10
so the base of the triangle is 10. now…
10 x 7 = 70/2 = 35
The area of the triangle is 35
Now the square
8 x 7 = 56
The area of the square is 56
Finally the rectangle
9 x 14 = 126
The area of the rectangle is 126
Now add the areas for all of the shapes
35 + 56 + 126 = 217 ft^2
The area of the figure is 217 ft^2
