The functions f(x) and g(x) are shown below f(x) = 5x g(x) = 5x Which statement best describes the graph of f(x) and g(x)?

Tasya [4]

The functions supplied appear to be the same? Regardless:

We have the equation y = 5x.
Therefore the gradient of this graph will be 5, so for every 1 increase in the y axis, there will be 5 in the x.

It will appear as a straight line passing through the origin and the point (1, 5).

Jane Marko buys a car for 43,900. in three years, the car depreciates 48% in value. how much is the car worth in three years ?

docker41 [41]

Let's take this step by step.

A car cost $43,900.

If it depreciates 48% in value in 3 years, we must find 48% of $43,900, and subtract that from its total value.

A 48% of $43,900 is:

$43,900 * 0.48 = $21,072

$43,900 - $21,072 = $22,828

The car is worth $22,828 in three years.

A set of n = 25 pairs of scores (x and y values) has a pearson correlation of r = 0.80. how much of the variance for the y score

enot [183]

0.64 or 64% of the variance for the y scores is predicted by its relationship with x.

<h3>What is coefficient of determination?</h3>

The percentage of the variation in the dependent variable that can be predicted from the independent variable is known as the coefficient of determination, abbreviated R2 or r2, in statistics.

<h3>How to find the variance for the y scores?</h3>

given that

A set of n = 25 pairs of scores (x and y values) has a pearson correlation of r = 0.80.

now we have to find the variance for the y scores.

here, r=0.80 then ${r}^{2} = 0.64$

which means 0.64 or 64% of the variance for the y scores is predicted by its relationship with x.

$r = \sqrt{ {r}^{2}} \: or \: \sqrt{ {r}^{2}} \\ 0.80 = \sqrt{ {0.80}^{2} } \\ 0.80 = 0.80$
