Answer:
A. 
or 4%
B. 
or 64%
C. 8 times
Step-by-step explanation:
The county-fair prize wheel has equally spaced sections with the following colors: 1 is golden, 2 are silver, 3 are green, 4 are blue, 6 are red, and 9 are yellow, 25 sections in total.
A. The probability of landing on gold is
or 4% as a percent.
B. If the probability of landing on yellow is 36% (or 0.36 as decimal), then the probability of not landing on yellow is
or 64% as a percent.
C. If the wheel is spun 1 time, the probabilty of landing on silver is
or 8% as a percent.
If the wheel is spun 100 times, the expected number of landing on silver is
75 because
9 = .12x
9/.12 = 75

when it comes to checking if a function is even or odd, it boils down to changing the argument, namely x = -x, and if the <u>resulting function is the same as the original</u>, then is even, if the <u>resulting function is the same as the original but negative</u>, is odd, if neither, well then neither :).
anyway, that said, let's first expand it and then plug in -x,
