Question

Medal
The table below shows the distance y, in miles, traveled by a toy car in x minutes:

Time (x)
(minutes)
10 20 30 40

Distance (y)
(miles)
4 8 12 15

Part A: What is the most likely value of the correlation coefficient of the data in the table? Based on the correlation coefficient, describe the relationship between time and distance traveled by the toy car.
[Choose the value of correlation coefficient from 1, 0.99, 0.5, 0.02]

Part B: What is the value of the slope of the graph of distance versus time between 10 minutes and 30 minutes, and what does the slope represent?

Answer 1

Part C: Does the data in the table represent correlation or causation? Explain your answer. (3 points)

Answer 3

still looking for help ?

Answer 4

yes sir

Answer 5

Look at the given table,
it seems the distance is `increasing` as time is increasing right ?

Answer 6

right

Answer 7

for part A :
Since the distance is increasing as time is increasing, this shows a strong positive correlation. The correlation coefficient could be 0.99

Answer 8

do you know how to work part B ?

Answer 9

you need to use slope formula

Answer 10

im not really good with the slope formula

Answer 11

Time (x)
(minutes)
`10` 20 `30` 40

Distance (y)
(miles)
`4` 8 `12` 15

Answer 12

(10, 4) and (30, 12) are the points

Answer 13

apply slope formula

Answer 14

ok let me try to type this without messing up lol

Answer 16

(10, 4) and (30, 12)
x1 y1 x2 y2

Answer 17

somthing like this

Answer 18

looks perfect!
simplify

Answer 19

yes simplify completely
