Answer:
C. 54.7
Step-by-step explanation:
mean is the average number. so you add all six numbers then divide by 6 which equals the average ( mean)
- hey diddle diddle the medians the middle
you add and divide for the mean
the mode is the one you see the most often
and the range is a difference between
30x-18 because 6•5x=30x and 6•3=18.
Answer:
The number 0 is excluded from the domain of f(x) because f(x) is a rational function which is not defined if the denominator is zero.
Step-by-step explanation:
The Rational Function is defined as:
with Q(x) ≠ 0
Because a rational function is not defined when the denominator is zero.
In this case, Q(x) (the denomitador of the given function) is x. Therefore the domain of the given function is given by all real numbers except the restrictions of the function (where the function is not defined).
f(x) is not defined at x=0, that's why the zero is excluded.
Answer:
2/4 = 1/2
Step-by-step explanation:
Firstly expand cos(x - 30)....which is..
[cos x.cos 30 + sin x.sin 30]
If sin x = -1/2...then cos x = square root of 3/2
Then substitute the values into the expansion above....which...,
[(square root of 3/2)(square root of 3/2) + (-1/2)(1/2) ]
; 3/4 - 1/4 = 2/4
;Ans = 2/4 = 1/2
