a) The point (140, 57) lies furthest from the rest of the data, therefore making it an outlier.
b) Since the points are all going in somewhat of a positive diagonal direction, there is a positive correlation.
c) We can estimate that the new student weighs approximately 155 kg.
Answer:
C.
Step-by-step explanation:
To find the volume of a cylinder the equation is pi times radius squared times height, the radius is half of the base so the radius is 2.5 inches so you have
pi(2.5)^2 h
This is all about proportions. You can make this into fractions:
3/5 = 12/x
A good way to handle this, is to make one of those numbers the same. If you do (3/5) * 4, you would get 12/20 (because 4 * 3 = 12 and 4 * 5 = 20)
So then you have this:
12/20 = 12/x
It's basically a fill in the blank from there. x= 20
Elena's team played 20 games
X+y=16
the sum of the squares is
x^2+y^2=sum
solve for y in first equation
x+y=16
y=16-x
subsitiute that for y in other equation
x^2+(16-x)^2=sum
x^2+x^2-32x+256=sum
2x^2-32x+256=sum
take derivitive to find the minimum value (or just find the vertex because the parabola opens up)
derivitive is
4x-32=derivitve of sum
the max/min is where the derivitive equals 0
4x-32=0
4x=32
x=8
at x=8
so then y=16-8=8
the smallest value then is 8^2+8^2=64+64=128
