Which scatterplot has a correlation coefficient closest to r = 1?
qwelly [4]

Answer:

The scatter diagram that contains the correlation coefficient closest to r = 1 is the first one shown in the attached images.

Step-by-step explanation:

The correlation coefficient "r" measures how much two variables x and y are related. When the variables are highly related, the value of r is closer to one and the points contained in the scatter diagrams are assimilated more and more to a line. When the value of r is positive the relation is crescent and therefore the slope of the line drawn by the points in the diagram has a positive slope


Therefore, to answer this question, one must search among the attached images for the dispersion diagram in which the points resemble a straight line with a positive slope.


The scatter diagram that meets the requirements mentioned is the first one that appears in the attached images

How much material is required to make a pipe that is 300 cm long whose outer diameter is 8 cm with an inner diameter of 5 cm? Sh
worty [1.4K]

Answer:

Step-by-step explanation:

If you had a solid cylinder, in order to find the amount of material that makes up that solid cylinder, you would find the volume using the radius of 4 (half of the diameter 8).  BUT we want to know the volume of the solid with the radius of 4 minus the solid that has a radius of 2.5 (half of the diameter 5).

V_o-V_i  That's volume outer - volume inner.  To find the outer volume:

V=\pi r^2h so

V_o=\pi (4^2)(300) and

V_o=4800\pi  and do the same for the inner volume:

V_i=\pi (2.5^2)(300) and

V_i=1875\pi

Subtract the inner from the outer:

4800\pi-1875\pi=2925\pi cm^3

If you need your answer in decimal form, then the volume is

9189.16 cm³
