To find the interquartile range, you will list the data that is presented in the stem and leaf plot.
Find the median of the data (30.5)
Find the median of the lower half and the median of the upper half.
Subtract these two values.
The data are <u>20</u>, 25, 30, 30, 31, 40, 41, <u>49</u>.
27.5 40.5
40.5-27.5 = 13
The interquartile range is 13.
The expression i determined is 10x + 6
Answer:
60 tickets for children were sold
Step-by-step explanation:
Let x be the number of sold children's tickets and let y be the number of adult tickets sold, then we can pose the following equations.
(i) Because 132 tickets were sold in total
(ii) because the total of $ obtained by sales was 931.20.
We must clear x. Then we substitute (i) in (ii)
60 tickets for children were sold
Answer:
A = 76.8 yd²
Step-by-step explanation:
The area (A) of a regular polygon is calculated as
A = 
pa ( p is the perimeter and a the apothem )
Here p = 8 × 4 = 32 yd and a = 4.8 yd , then
A = × 32 × 4.8 = 16 × 4.8 = 76.8 yd²
If you want to know what percent did Mr. Yoshikawa graded you can say:
60/75 = ?/100 so ? is:
60*100/75 = 80 % so he graded 80% of the papers and the rest of the papers was graded by his student so:
100% - 80% = 20% so his student graded 20% of the papers :)))
i hope this is helpful
have a nice day
