A group of students want to determine if a person's height is linearly related to the distance they are able to jump.
Levart [38]

The correlation coefficient between the student's height and the distance they were able to jump is 0.86.

<h3>What is the correlation coefficient?</h3>

The correlation coefficient is a number that ranges from -1 to 1. It shows the strength of the relationship between two variables. It also shows the direction of the relationship.

Positive correlation is when the two variables move in the same direction. If one variable increases, the other variable also increases. Negative correlation is when two variables move in different direction. If one variable increases, the other variable decreases. Zero correlation is when there is no relationship between the variables.

The correlation coefficient is calculated using a financial calculator.

Here is the complete question:

A group of students want to determine if a person's height is linearly related to the distance they are able to jump.

To determine the relationship between a person's height and the distance they are able to jump, the group of students measured the height, in inches, of each person in their class and then measured the distance, in feet, they were able to jump from a marked starting point.

Each student was given three tries at the jump and their longest jump distance was recorded. The data the students collected is shown below.

Enter the correlation coefficient. Round your answer to the nearest hundredth.

Which expression shows the area of the shaded part of the grid? A hundred grid model showing a 7 4 array shaded blue. A. 0.04 ×
aksik [14]

Answer:

C.\ Area = 0.4 * 0.7

Step-by-step explanation:

See attachment for grid

From the attachment:

There are 10 cells on the horizontal axis and there are also 10 cells on the vertical axis.

This implies that, the measurement of each cell is:

Each\ Cell = \frac{10}{10 * 10}

Each\ Cell = \frac{1}{10}

Each\ Cell = 0.10

The horizontal axis has 7 selected cells.

This measures

Horizontal = 7 * 0.10 = 0.70

The vertical axis has 4 selected cells.

This measures

Vertical = 4 * 0.10 = 0.40

So, the selected area is:

Area = Vertical * Horizontal

Area = 0.40 * 0.70

or

Area = 0.4 * 0.7

What is the easiest to understand formula for solving 45 45 90 special right triangles?
alexgriva [62]

Step-by-step explanation:

45°, 45°, 90° triangle theorem states that:

Lengths of the sides opposite to the 45° angle are equal to one upon root two times of the length of hypotenuse.

Mathematically it can be expressed as:

length \: of \: sides \: opposite \: to \: 45 \degree \: \\  angle \\  =  \frac{1}{ \sqrt{2} }  \times length \: of \: hypotenuse.
