This equation shows how the amount of jam Jenna has jarred is related to the number of days she has spent making jam.
1 answer:
Jenna need 2 days to make jam if she wants to jar 12 litres of jam in all.
Step-by-step explanation:
The equation shows the amount of jam Jenna has jarred is related to the number of days she has spent making jam.
where j represents the amount of jam jarred and d represents the number of days spent making jam.
To find the number of days that Jenna will need if she wants to jar 12 litres of jam is to substitute in
Dividing 6 on both sides, we get,
Thus, Jenna need 2 days to make jam if she wants to jar 12 litres of jam in all.

Jason's scores : 80 90 95 85 70 and
Jill's score : 70 75 90 100 95.
Mean of Jason's scores =
Mean of Jill's scores =
Now, in order to find the mean absolute deviation, need to find the difference of each score from means.
<u>Mean absolute deviation for Jason's scores.</u>
|84-80| = 4
|84-90| = 6
|84-95| = 9
|84-85| = 1
|84-70|= 14
<u>Mean absolute deviation for Jill's scores</u>
|86-70| = 16
|86-75| = 11
|86-90| = 4
|86-100| = 14
|86-95|= 9
Jill got average quiz score 86 and Jason got 84.
Therefore, Jill got better quiz average.
Also, the mean absolute deviation for Jason scores is less that is 6.8 than 10.8.
Therefore, Jason got more consistent grades.
