Answer:
1600
Step-by-step explanation:
Do 400 ÷ 0.25 = 1600
0.25 because of the discount
Check by doing 1600 X 0.25 and it should be 400 which it is

Answer:
The answer is b.)
Step-by-step explanation:
There are 38 slots in which the ball can land .
2 of the slots are green
18 of the slots are red
18 of the slots are black
The wheel is spun twice. The outcome of both the spins are independent of each other.
Therefore the probability, p(ball lands on red the first time and black the second time)
= p( ball lands on any one of 18 red slots) × p(ball lands on any one of 18 black slots)
=
The answer is b.)
<span> f(x) = 3(1/2)x is not properly formed; if you meant exponentiation here, please write the function as
f(x) = </span><span> f(x) = 3(1/2)^x.
The range is the set of all possible values of y (that is, all possible values of f(x). Try out a few x values and see what you get:
f(-5) = 3(1/2)^5 (note that this is positive)
f(0) = 3(1/2)^0 = 3 (this is positive)
f(4) = 3(1/2)^4 = 3/16 (this is positive)
There is no x value for which f is negative, and none for which f is 0. Given this info, what do YOU think the range of </span><span> f(x) = 3(1/2)^x is?
Write it in the form (a,b).</span>
