which scatterplot shows a strong association between two variables even though the correlation is probably near zero?

worty [1.4K]

The scatterplot that shows a strong association between two variables even if the correlation is near zero is graph C.

<h3>What is zero correlation?</h3>

Correlation is a measure that is used in statistics to measure the linear relationship that exists between two variables.

Zero correlation is when there is no linear relationship between the variables been studied. When it is shown on a graph, zero correlation would have no clear linear trend either positive or negative. A linear trend is roughly a straight line. A linear trend is positive if it slopes upward and negative if it slopes downward.

xz_007 [3.2K]

Given:
15 students
2 students must be chosen.
No repetition, no order

This is a combinations problem. We use this formula: n! / (n-r)!(r!)

n = 15 ; r = 2

15! / (15-2)!(r!) ⇒ 15! / 13! * 2! = 105

A square is a rectangle with equal sides.<br> True or False?

Digiron [165]

<h3>Answer: True</h3>

Explanation:

A rectangle has all four angles that are 90 degrees. The side lengths may or may not all be the same length; however, we do know that the opposite sides are the same length.

A square is a special type of rectangle where all four sides are the same length and all angles are 90 degrees.

If a figure is a square, then it is automatically a rectangle, but not the other way around.

A piano has 52 white keys. Write and use an equation to find the number of octaves on a piano keyboard.

Firdavs [7]

There are 7 keys in each octave (C,D,E,F,G,A and B) so it would make sense to divide 52 to 7.
52/7=7 octaves and 3 extra kets
