Answer:
x = 66
Step-by-step explanation:
For a set of N numbers:
{x₁, x₂, ..., xₙ}
The mean can be calculated as:
In this case we have the data set:
{98, 122, 104, 115, 107, x}
And I assume that we want to have the mean = 102.
So we have a set of 6 numbers, the mean of this set will be:
We need to solve this equation for x.
If we multiply both sides by 6, we get:
(98 + 122 + 104 + 115 + 107 + x) = 102*6 = 612
546 + x = 612
x = 612 - 546 = 66
x = 66
Answer:
The volume of the pyramid is not equal to the volume of the cylinder.
Step-by-step explanation:
A right cylinder has the circular cross-sectional area and if the cross-sectional areas of a right pyramid and a right cylinder are the same then the pyramid must be a right circular cone.
Now, the volume of a right cylinder is πr²h and that of a right circular cone is 1/3 πr²h.
Therefore, the radius of the base of the cone and that of the cylinder is the same and their heights are equal to be 5 units, then the volume of the pyramid is not equal to the volume of the cylinder. (Answer)
Answer:
A
Step-by-step explanation:
You can eliminate B and D because it’s using 
, but the question is asking 
. So it’s either A or C. They are both written correctly, but out of the two, A is correct because just that x ≠ 
part of it is what makes it true.
The reason being is that the only thing that won’t make 
true is when the denominator equals 0, because anything divided by 0 is undefined. So, when you plug for x in the denominator you get: 
. The 
part just turns into 7, and 7 - 7 is 0. So you don’t want x to equal .
<u>So the answer is A:</u> 
, 
±
There you go my friend!
I hope you understand and that this helps with your question! :)
