Answer:
I will explain each one under this is.
Step-by-step explanation:
The answer to the blank space in number 2 is 8 because you would need to take the bigger denominator and then divide it by the lower denominate to find out the equivalent fraction. And for number two, you would divide 28 by 7 which equals 4, so you then take 4 and take the numerator and multiply the numerator by 2, so that's 2 times 4 which is 8. So the answer 8 in the blank space. Since I already explained how to do it here, I'll just give you the rest of the answers.
3: 20
4: 33
5: 5
6: 100
7: 28.8
8: 5.7
This can be solve by just knowing what is amount that is going
to be yours and the amount that you will need to give for the prize. So the
expected value of your gain is
[$2/ ticket (1500 tickets)] – ( $500 + $250 + 150 + $650) =
$2035 is the expected gain
F(x) is the function that represents a given equation. It is defined more specifically by rules or conditions to satisfy the whole formula/equation.
In this case, f(x) has an inverse proportion with x (e.g. f(x) = 1/x). The second parameter says that f(x) = -15 when x is 30. Given that condition, just look for the formula, among the choices, that will result to -15 when x = 30. The answer is:
D. f(x) = -450/x
This is just -450/30 = -15
