It's not an accurate value for the data based on the scatter plot, r = 0.01 is not an accurate value for this data, because 0.01 means practically no correlation, while the points on the graph are moderately correlated

<h3>How to illustrate the information?</h3>

1. Part A:

Since the points in the scatter plot shows a moderated upward trend, you must expect a correlation coefficient close to ± 0.5. A correlation coefficient of 0.01 is too close to 0, which would mean that the points are almost not correlated at all.

The correlation coefficients, r, measure the strength of the correlation of two variables and they can have values from - 1 to  1.

Here, r = - 1 is a perfect negative correlation as the points will adjust perfectly to a line with a negative slope.

r =  + 1 is a perfect positive correlation: the points will adjust perfectly to a line with a positive slope.

r = 0 means that the variables are not correlated at all.

Hence, the closer to zero, the worse the correlation is, and that is what r = 0.01 means, but the graph shows another thing.

Therefore, the calculated value of r = 0.01 is not accurate for this scatter plot.

2. Part B.

A causal relationship means that the explanatory variable (the independent variable) is the cause of the dependent variable.

Hence, you must find a reasonable variable that can be the cause of the number of strawberries picked.

Thus, the scenario could be:

Amount of rainfall in mm (x)         Number of strawberries picked (y)

      100                                                     20

        50                                                     40

        25                                                     80

        12.5                                                  160

        6.25                                                 320

The amount of rainfall is the cause of the number of strawberries picked, and you could find a model that relates both variables.

Find the missing length of the triangle.
AysviL [449]

Answer:

12 in.

Step-by-step explanation:

Leg = a = 9 in.

Leg = b

Hypotenuse (side opposite of the right angle) = c = 15 in.

Use the pythagorean theorem to find the missing side length

a^2 + b ^2 = c ^2

9^2 + b^2 = 15^2

Simplify

81 + b^2 = 225

Subtract 81 from both sides of the equation

b^2 = 144

Find the square root of 144

b = \sqrt{144}

b = 12

12 in

Hope this helps :)
