It would be: 28*15 / 100 = 420 / 100 = 4.2
To find the range subtract from the biggest to the lowest, so it would be 86 - 13 which equals to 73.
Your lower or first quartile would be 42 and your upper or third quartile would be 74.
Find the equation of the line
slope=(y2-y1)/(x2-x1)
slope=(6-2)/(7-(-3))=4/10=2/5
slope is 2/5
y=mx+b
y=2/5x+b find b
input a point
6=2/5(7)+b
6=14/5+b
minus 14/5 from both sides
3 and 1/5=b
16/5=b
xintercept is when y=0
0=2/5x+16/5
minus 16/5 from both sides
-16/5=2/5x
times both sides by 5/2 to clear fraction
-8=x
xintercept is -8 or (-8,0)
The slopes of perpendicular lines are negative reciprocals.The slope of the given line is 4.The slope of the perpendicular is -1/4.
Now we need to find the equation of a line that has slope -1/4 and passes through the point (4, 20).
We use the point-slope form of the equation of a line, where m = slope, and the point is (x1, y1).
y - y1 = m(x - x1)
y - 20 = -1/4(x - 4)
-4y + 80 = x - 4
x + 4y = 84
Hi there!
Find the volume of a sphere using the following equation:
V = 4/3πr³
Substitute in the given radius:
V = 4/3π(1)³
V = 4/3π or ≈ 4.19 units³
