Answer:
Step-by-step explanation:
1) False: The function is decreasing (because the base, 1/3, is between 0 and 1).
2) True: The function is decreasing (see #1, above)
3) False: There is no x-intercept.
4) True: If x is 0, then y = (1/3)^0 = 1.
5) False: the range consists of the set of all real numbers greater than zero.
Answer:
( f + g) (x) = –2x + 6 ( f – g) (x) = 8x – 2 ( f × g ) (x) = –15x 2 + 2x + 8

Answer: Yes, we have.
Step-by-step explanation:
Going by the details provided, Probability of success of choosing a citizen with a fitness band 27%
The probability function for expected value shows the Formula to know with sufficient dependence what proportion of the sampled people will have the fitness band.
Since 27% of 500 = 135.
and 135 is more than a quarter of 500(125), then we have enough Evidence that more than a quarter of this age group own a fitness band.
Answer:
slope of line is 3
y-intercept of line is -13
Explanation:
The general formula of the linear line is:
y = mx + c
where:
m is the slope of the line
c is the y-intercept
The given line is:
y = 3x - 13
Comparing the given line with the general formula, we would find that:
m (the slope of the line) is 3
c (the y-intercept) is -13
Hope this helps :)
