The scale model of a car is 5% of the size of the actual car. The length of
podryga [215]
<h3>Answer:  15 feet</h3>

Explanation:

x = length of the actual car in inches

5% of x = 9 inches

0.05x = 9

x = 9/(0.05)

x = 180 inches

Divide by 12 to convert from inches to feet.

180 inches = (180/12) feet = 15 feet

Find the residual values, and use the graphing calculator tool to make a residual plot. A 4-column table with 5 rows. The first
Svetlanka [38]

The best answer from the options that proves that the residual plot shows that the line of best fit is appropriate for the data is: ( Statement 1 ) Yes, because the points have no clear pattern

X         Given     Predicted     Residual value

1            3.5           4.06             -0.56

2           2.3           2.09             0.21

3            1.1            0.12               0.98

4           2.2           -1.85              4.05

5          -4.1            -3.82            -0.28

The residual value is calculated as follows using this formula: ( Given - predicted )

1) ( 3.5 - 4.06 ) = -0.56

2) ( 2.3 - 2.09 ) = 0.21

3) ( 1.1 - 0.12 ) = 0.98

4) (2.2 - (-1.85) = 4.05

5) ( -4.1 - (-3.82) = -0.28

Residual values are the difference between the given values and the predicted values in a given data set and the residual plot is used to represent these values .

attached below is the residual plot of the data set

hence we can conclude from the residual plot attached below that the line of best fit is appropriate for the data because the points have no clear pattern ( i.e. scattered )

A relief package is released form a helicopter at 1600 feet. The height of the package can be modeled by h=16t^2 + 1600, where h
postnew [5]
The equation is <span>h(t) = -16t2 + 1600</span>. 
When the package hits the ground, h(t) = 0: 0 = -16t2 + 1600 To solve by factoring: 0 = -16(t2-100)0 = -16(t+10)(t-10) t = -10 and +10 seconds. 

Since we aren't interested in negative time, t = 10 seconds.

Lee records the height of players on a basketball team, and calculates the mean absolute deviation of the set of data. What does
Luba_88 [7]

The mean absolute deviation can be defined as the average distance between the mean and each of the given data points. It is the absolute value of the deviation.

To find the mean absolute deviation, take the folllowing steps:

1. Find the Mean

2. Find the distance of each value from the mean by Subtracting the mean value from each value

3. Find the mean of the distances

Therefore, the mean absolute standard deviation of the set of data describes the average difference in height between each player and the mean height

ANSWER:

The average difference in height between each player and the mean height
