To compare the two classes, the Coefficient of Variation (COV) can be used.
The formula for COV is this:
C = s / x
where s is the standard deviation and x is the mean
For the first class:
C1 = 10.2 / 75.5
C1 = 0.1351 (13.51%)
For the second class:
C2 = 22.5 / 75.5
C2 = 0.2980 (29.80%)
The COV is a test of homogeneity. Looking at the values, the first class has more students having a grade closer to the average than the second class.
So a day is 24 hours
24/6=4
4*5=20
so they spend 20 hours a day sleeping
here’s a full on equation
(24/6)*5
Answer:
Step-by-step explanation:
We are given that
Initial value problem
, y(3)=4
Substitute the value 
When t=3 and y=4 then
z=3+4=7
Differentiate z w.r.t t
Then, we get
Integrate on both sides
Substitute t=3 and z=7
Then, we get
Substitute the value of C then we get
Answer:
y = 5x - 22
Step-by-step explanation:
In this question, we have to find the equation of the line.
We know that the slope is 5 and passes through (5, 3) on the graph.
We know that our equation must be in slope-intercept form: y = mx + b
To find our y-intercept, or "b", we would plug in our given information and solve for b.
Solve for b:
3 = 5(5) + b
3 = 25 + b
Subtract 25 from both sides.
-22 = b
This means that our y-intercept is -22. We can now make our equation with our new information:
y = 5x - 22
The equation of the line is y = 5x - 22
Divide it by 3.14 (pi) then find the square root it and the answer is 2 the radius is 2 square meters
