Answer:
70 in
Step-by-step explanation:
Answer:
55.5
Step-by-step explanation:
find the median - in this case it's 60
then group the upper and lower halves of the data:
(11, 19, 35, 42) 60 (72, 80, 85, 88)
now we find the medians of those sets:
35 + 19/2 = 54/2 =27
80 + 85/2 = 165/2 = 82.5
then subtract those two medians to find the interquartile:
82.5 - 27 = 55.5
The percentage increase in staff was 60.6%.
Answer:
-2(-3n - 12)
Step-by-step explanation:
The first answer would be 44. You just need to add all the numbers together. For the second one the formula for area of a trapezoid is a+b/2*h. So you have to add both bases and divide them by 2 and that multiply that by the height. So if you do the math your answer should be 115. I hope this helps love! :)
