Answer:
2.25
Step-by-step explanation:
The computation of the number c that satisfied is shown below:
Given that
Interval = (0,9)
According to the Rolle's mean value theorem,
If f(x) is continuous in {a,b) and it is distinct also
And, f(a) ≠ f(b) so its existance should be at least one value
i.e
After this,
After this,
Put the values of a and b to the above equation
= 2.25
Answer:
2, 4.5 and 8
Step-by-step explanation:
(1)
The mode is the number which occurs most often , then
mode = 2
(2)
The median is the middle value of the numbers arranged in ascending order. If there is no exact middle value then it is the average of the numbers either side of the middle.
1, 2, 2, 3, 4, 5, 6, 7, 8, 9
↑ middle
median = =
= 4.5
(3)
The range is the difference between the largest and smallest values
range = 9 - 1 = 8
