A statement which best describes the strength of the correlation, and the causation between the variables is that: D. it is a strong positive correlation, and it is likely causal.

<h3>What is a positive correlation?</h3>

A positive correlation can be defined as a terminology that is used to described a scenario (situation) in which two variables move in the same direction and are in tandem.

This ultimately implies that, a positive correlation exist when two variables have a linear relationship or are in direct proportion. Hence, when one variable increases, the other increases as well, and vice-versa.

By critically observing the scatter plot (see attachment) which models the data in the given table, we can infer and logically deduce that the value on the y-axis (circumference) increases as the value on the x-axis (radius) increases, so this is a strong positive correlation.

Also, we know that there exist a direct relationship between the circumference of a circle and its radius, so this relationship is most likely causal.

In conclusion, a statement which best describes the strength of the correlation, and the causation between the variables is that it's a strong positive correlation, and it is likely causal.

Dhani has 4 cards numbered 1 through 4. He removes 2 cards at random and adds their values.
DanielleElmas [232]

Answer:

2/3

Step-by-step explanation:

The total number of sums (not distinct) is 4\cdot 3=12, because we're removing without replacement.

Count the sums that fit the stipulation (sum \leq 5):

1,2,\\2,1\\1,3\\3,1\\1, 4\\4, 1\\2, 3, \\3,2

There are 8 sums that work. Therefore, the desired answer is \frac{8}{12}=\boxed{\frac{2}{3}}

Can anyone explain these?
Paul [167]
The perimeter , width and length are all one dimensional so the preimeter of the resulting rectangle  will be 2.5 * 36 = 90.

The area  is 2 dimensional  whereas the vase and height are one dimensional so the area will be increased by a factor of 5^2  ( or 25)
New  rea =  36*25 =  900

solids are 3 dimensional  so the ratio of thereir volumes is  5^3 : 3^3
= 125:27

to answer the last 2 use the formula Volume = pi r^2 h  where r = radius and h = height of a cylinder
