The answer is c because if you do the math it’s 15/2
<span>y = 3x - 7
3 = slope
-7 = y intercept
This line would cross the y intercept at -7, and go up by 3 (slope). </span>
I think its only B because it's the only one I see that is enlivenment.<span />
The height of the cylinder will be 5 units based on the information given.
<h3>How to calculate the height?</h3>
The cylinder has a volume of 45π cubic meters and the radius is 3 units.
The height will be calculated thus:
Volume of a cylinder = πr²h
45π = πr²h
45π = π(3²)h
45π = 9πh
h = 45π/9π
h = 5
Therefore, the height of the cylinder will be 5. units.

❤️Hello!❤️For experimental data it may be good to use linear regression.
For precise data you do not need linear regression.
Step-by-step explanation: If you have a number of experimentally generated data points that are subject to inaccuracies then you can use something like linear regression to generate a linear model that fits the data reasonably well. Many modern calculators have a linear regression capability.
On the other hand, if you are given precise data, you should be able to generate a model that fits the data exactly. For example, given points (
x
1
,
y
1
) and (
x
2
,
y
2
) which are supposed to lie on a line, the equation of the line in point-slope form is:
y

=
m
(

=
