cody has a box of cereal. on monday he ate 1/7 of the cereal. on tuesday, he ate 1/6 of the remaining cereal. what fraction of t
1 answer:
So, on Monday he ate 1/7, that means from a whole 7/7, take away 1/7, the leftover was 6/7 then.
on Tuesday, he ate 1/6 of the leftover, namely, 1/6 of 6/7.
now, how much is 1/6 of 6/7? well, is just their product,
now, so he really ate 1/7 of the whole thing on Tuesday, there were 6/7 remaining, how much is 6/7 - 1/7? yeap, you guessed it, 5/7.

Answer:
a)
We have a perfect linear relationship between the two variables
b)
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
c) For this case the slope indicates that for each increase of the number of hours in 1 unit we have an expected increase in the score about 6 units.
And the intercept 5 represent the minimum score expected for any game
Step-by-step explanation:
We have the following data:
Number of hours spent practicing (x) 0 0.5 1 1.5 2 2.5 3 3.5 4
Score in the game (y) 5 8 11 14 17 20 23 26 29
Part a
The correlation coefficient is given:
For our case we have this:
n=9
We have a perfect linear relationship between the two variables
Part b
Where:
With these we can find the sums:
And the slope would be:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
Part c
For this case the slope indicates that for each increase of the number of hours in 1 unit we have an expected increase in the score about 6 units.
And the intercept 5 represent the minimum score expected for any game
Try this solution, it consists of two parts (MN=8).
