Answer:
81.11 in decimal
81 1/9 in fraction
Step-by-step explanation:
Let the number be x
1.9 time a number is equal to 1.9x
1.7 plus 1.9 times a number is equal to 1.7 + 1.9x
Now given that
1.7 plus 1.9 times a number equals the sum of the number and 74.7
mathematically we have relation equation as
1.7 + 1.9x = x + 74.7
subtracting 1.7 from both side
1.7 + 1.9x - 1.7 = x + 74.7 - 1.7
=> 1.9x = x + 73
subtracting x from both side
1.9x - x = x + 73 - x
0.9x = 73
dividing both side by 0.9
0.9x/0.9 = 73/0.9
x = 81.11 or 81 1/9
Thus, the number is
81.11 in decimal
81 1/9 in fraction
Answer: A. Paul’s data has a bigger overall spread than Sally’s data
The range of Paul’s Data: 28-12=16
The range of Sally’s Data: 30-15=15
16>15. Therefore Paul’s data has a bigger overall spread than Sally’s
Why B is wrong: Remember that the interquartile range is the “box” range.
Paul’s IQR: 26-15=11
Sally’s IQR: 28-18=10
11<10 is false, so B is false.
Why C and D is wrong: The middle line in the IQR represented in each box and whisker plot is the median. Paul’s median is not equal nor greater than Sally’s median. 18=24 18<24 is false. Therefore, C and D are false.
