Answer:
IQR = 6
Step-by-step explanation:
Given:
The given set of data is:
40 41 42 43 44 45 46 47 48 49 50
Number of terms, 
Therefore, the median is given as
term which is the sixth term. Median = 45
(40 41 42 43 44) <u>45</u> (46 47 48 49 50 )
Now, we find the median of the lower half (
) and upper half (
)of the data that are before and after the median.
The lower half of the data has the values 40 41 <u>42</u> 43 44.
Number of terms are 5. So, median is the third term which is, 
The upper half of the data has the values 46 47 <u>48</u> 49 50.
Number of terms are 5. So, median is the third term which is, 
Now, IQR is given as the difference of upper half median and lower half median.

The population before the increase was 894.
Answer:
y=-4/23
im not sure i didn't check (might be wrong)
Step-by-step explanation:
4x - 5y = -28
-3x - 2y = 10
then make x the same
So
12x-15y=-84
-12x-8y=80
then its left with
-23y=-4
y=-4/23
find x by entering y into -3x - 2y = 10 and solving
