Answer:
increase
Step-by-step explanation:
- Given data is: 71, 67, 67, 17, 69, 84, 21, 87
- Arranging in ascending order we find: 17, 21, 67, 67, 69, 71, 84, 87
- 4th term = 67, 5th term = 69
- -> median = Sum of 4th and 5th term/2 = (67 + 69)/2 = 132/2 = 66
- Now, when one of the 67 is replaced by 71, the new data set in ascending order will be: 17, 21, 67, 69, 71, 71, 84, 87
- Here, 4th term = 69, 5th term = 71
- New median = (69 + 71)/2 = 140/2 = 70
- -> new median > initial median
CONCLUSION: Median will increase if the number 71 replaced one of the 67's in the set.
Answer:
t greater than or less than -10

Answer: 16 1/2
Step-by-step explanation:
It's easiest to multiply improper fractions and then to convert them back into mixed numbers, so 4 1/2 would become 9/2 and 3 2/3 would become 11/3.
= 99/6. Now just simplify to 33/2 and then convert back into a mixed number. 16 1/2

Answer:
The answer is "Option C".
Step-by-step explanation:
Given:
![\to f(x)=2x^2-3x+1\\\\when \ x=1\\\\\to f(1)= 2(1)^2-3(1)+1\\\\\to f(1)= 2(1)-3+1\\\\\to f(1)= 2-3+1\\\\\to f(1)=-1+1\\\\\to f(1)=0](https://tex.z-dn.net/?f=%5Cto%20f%28x%29%3D2x%5E2-3x%2B1%5C%5C%5C%5Cwhen%20%5C%20x%3D1%5C%5C%5C%5C%5Cto%20f%281%29%3D%202%281%29%5E2-3%281%29%2B1%5C%5C%5C%5C%5Cto%20f%281%29%3D%202%281%29-3%2B1%5C%5C%5C%5C%5Cto%20f%281%29%3D%202-3%2B1%5C%5C%5C%5C%5Cto%20f%281%29%3D-1%2B1%5C%5C%5C%5C%5Cto%20f%281%29%3D0)
That's why choice C is correct.
