Answer:
B. 35%
Step-by-step explanation:
P(winning $1.00)=40%
P(winning $5.00)=20%
P(winning $10.00)=5%
In a probability distribution, the sum of the probability must always be equal to 1.
Therefore:
P(winning $0.00)=1-(40%+20%+5%)
=1-(0.4+0.2+0.05)
=1-0.65
=0.35
The probability of winning nothing at all is 35%.

Answer:
c = 2.25
Step-by-step explanation:
f(x) is a continuous and differentiable function on the interval, so the Mean Value Theorem guarantees a value for c exists.
The average slope is ...
m = (f(4) -f(1))/(4 -1) = (24 -12)/3 = 4
The point at which the derivative is 4 is ...
f'(c) = 6/√c = 4
√c = 6/4
c = 2.25
4. 3x-27 = 90
3x = 63
x = 21
5. 2x+30 = 60
2x = 30
x = 15
Distance = speed x time
speed = distance/time
time = distance / speed
400m/36s = 11 1/9 m per second
