TRUE or FALSE: The square root of R2 (the coefficient of determination) is r, the correlation coefficient. (remember that square

roots are always positive)

The The square root of R² (the coefficient of determination) is not r, the correlation coefficient. Therefore, it's false.

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

It should be noted that the correlation coefficient is used to measure how string the relationship between two variables are.

The correlation formula tells us the linear relationship between the variables. R² is the square of the correlation coefficient.

The yellow rose taxi service charges $1.75 per passenger and $2.25 per mile for a ride . How much will the yellow rose taxi serv
Ann [662]

Answer:

$40.50 for the miles and 1.75 x P (passangers)

Step-by-step explanation:

Since $2.25 is the fee for miles, 2.25 x 18 = $40.50

and since it depends on the group, ima say its probably 3, the passenger fee would be $5.25

that would add up to about $45.75

but if there is a different amount of passengers, just multiply it by $1.75 then add it to $40.50!

The shape below is a composite figure made up of two rectangular prisms, what is the volume of the figure?
Shkiper50 [21]

Answer:

11098{cm}^{3}

Step-by-step explanation:

The formula to find the volume of a rectangular prism is

v = length \times \: width  \times height

Since there are 2 shapes we are going to find the volume of each of them, then add them to find the volume of the entire shape.

The length of the rectangle that is standing is 62 cm, its width is 3 cm and its height is 13 cm. Therefore the volume is:

v = l \times w \times h \\ v = 62 \times 3 \times 13 = 2418 {cm}^{3}

On the other hand, the length of the rectangle that is lying down is 62 cm, its width is 20 cm <em>(</em><em>2</em><em>3</em><em>-3</em><em>=</em><em>20</em><em>)</em>, and the height is 7 cm. Therefore the volume is:

v = l \times w \times h \\ v = 62 \times 20 \times 7 = 8680 {cm}^{3}

The volume of the entire shape would then be:

2418 {cm}^{3}  + 8680 {cm}^{3}  = 11098 {cm}^{3}
