Can we predict how fast a tennis player can hit a serve from the playerâs height? The following computer output and scatterplot

olga_2 [115]

Complete question :

The computer output and scatter plot output pertaining to the question can be found in the attached picture.

Answer:

Kindly check explanation

Step-by-step explanation:

A.) Relationship between height and fastest serve speed :

According to the scatterplot and Correlation Coefficient (R) value which can be obtauned by getting the square root of R²

R = √27.7%

R = 0.5263 = 52.63% ; this depicts a fairly strong positive correlation or relationship between height and fastest serve speed

B.)

Equation of least square regression line :

From the computer output and scatter plot above :

Recall :

y = mx + c

y =predicted variable (s fastest serve)

m= slope

x = predictor variable (height)

c = intercept

y = 84.98x + 68.81

C.) 27.7% of the variation in fastest speed can be explained by height while the remaining percentage is due to other variables

D.) fastest serve of tennis player with height 1.7m

y = 84.98x + 68.81

y = 84.98(1.7) + 68.81

y = 213.276km/hr

E.)

R = √27.7%

R = 0.5263 = 52.63% ; this depicts a fairly strong positive correlation or relationship between height and fastest serve speed

F.)

Height = 2.06m = x

y = 84.98(2.06) + 68.81

y = 243.8688 km/hr

Residual = Actual - predicted

Actual = 230 ; predicted = 243.8688

Residual = 230 - 243.8688

Residual = −13.8688

Hence, the model overestimated fastest serve speed of a 2.06 m tall player by −13.8688 km/hr

A prism with a base area of 5 ft² and a height of 10 ft is dilated by a factor of 65 . What is the volume of the dilated prism?

mina [271]

Answer:

The volume of the dilated prism is $86.4ft^3$ .

Step-by-step explanation:

The original prism has base area $5ft^2$ and a height of $10ft$ .

The volume of the original prism is $v=5\times 10=50ft^3$ .

The prism is dilated by a scale factor of $k=\frac{6}{5}$ .

To find the volume of the dilated prism, we multiply the volume of the original prism by $k^3=\frac{216}{125}$ .

$V=\frac{216}{125} \times 50ft^3$

$\Rightarrow V=86.4ft^3$

A city determines that a planned community must have at least 4 acres of developed and open space, and the difference between th

Bezzdna [24]

Answer:

The graph in the attached figure

Step-by-step explanation:

Let

x ----> the number of open acres

y ----> the number of developed acres

we know that

$x+y \geq 4$ -----> inequality A

The solution of the inequality A is the shaded area above the solid line $x+y=4$

$y-x\leq 1$ -----> inequality B

The solution of the inequality B is the shaded area below the solid line $y-x=1$

so

The graph in the attached figure
