Answer:
x = 7 & y = 8
Step-by-step explanation:
We know that
Mean = Sum of terms/Total terms
=> Mean = 4 + 6 + x + y + 10/5
=> Mean = 20 + x + y/5
Now,
Median = (n + 1)/2
=> Median = (5 + 1)/2
=> Median = 6/3
=> Median = 3rd term = x
So,
x = 20 + x + y/5
x × 5 = 20 + x + y
5x = 20 + x + y
5x - x = 20 + y
4x = 20 + y
Since x and y are in order so,
Possible outcomes will be 7,8 & 9
(7,8) & (8,9) & (7,9)
Taking x = 7 and y = 8
4(7) = 20 + 8
28 = 28
Hence,
x = 7 and y = 8
Answer:
Example: f(x) = (1 + x + x^2) / x, x=0 is excluded from the domain, since division by zero is undefined.
Step-by-step explanation:
4 - t = 3(t - 1) - 5
= 4 - t = (3t - 3) - 5
= 4 - t = 3t - 8
Add 8 to both sides:
12 - t = 3t
Add t on both sides:
12 = 4t
Divide both sides by 4:
t = 3
Hope I helped :)
EDIT: Yeah I see where I went wrong - answer is 3
Mean: Add up all of the values then divide by the number of values
Ex. 3+5+2 = 10 divided by three
