Answer:
Interquartile range IQR = 5.5
Step-by-step explanation:
Interquartile range IQR = third quartile Q3 - first quartile Q1
IQR = Q3 - Q1 ........1
arranging the data in ascending order;
1,3,5,6,6,7,8,11,12
The median of the data is the 5th number which is 6
Separating the data into two halves;
(1,3,5,6,),6,(7,8,11,12)
The first quartile Q1 is; (the median of the first half)
Q1 = (3+5)/2 = 4
The third quartile Q3 is; (the median of the second half)
Q3 = (8+11)/2 = 9.5
The interquartile range IQR can be derived using equation 1;
IQR = Q3 - Q1 = 9.5 - 4
IQR = 5.5
Answer:
(900 ÷ 4) x 10 -200 = 2050 And this will equal last Summer's earnings
Step-by-step explanation:
So we know that 900$ is equal to 40% and that we can simplify this
900 ÷ 4 = 225
40% ÷ 4 = 10%
Therefore:
225 = 10% and
2250 = 100% of earnings
