X = 6.

Explanation:
Well we know that x + 12 must equal 3x, because the length of a cone is the same no matter where you look at it. Now we must write it out as an algebraic equation to solve for x

x+ 12 = 3x

1) We want to have x just on one side, so we subtract 1x (or x) from both sides
x - x + 12 = 3x - x
12 = 2x

2) We wan to have one x instead of 2, so we divide both sides by 2
12/2 = 2x/2
6 = x
x = 6

creativ13 [48]

Answer: y = 2/5 x + 2

Step-by-step explanation:

why not do this one too yk

slope = y2 - y1 / x2 - x1

4 - 2 / 5 - 0

slope = 2/5

ill use (5,4) for the y=mx+b initial equation

y = mx+b

4 = (2/5)(5) +b

4 = 2 + b

2 = b

now for the final equation whoop whoop

y = 2/5 x + 2

There are two calculus classes at your school. Both classes have a class average of 75.5. The first class has a standard deviati
Korvikt [17]
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.
