Answer:
f(x)=38x+b
Linear Equation
Step-by-step explanation:
So I used slope intercept form it 38 per bicycle and plus the costs of running but we don't know the cost so it's shown as b, the reason I did not use Exponential because from reading the word problem it's not going to grow rapidly.
Answer:
The expected value is -$0.17
Since it gives a negative expected value, the game is not favorable and should not be played
Step-by-step explanation:
Here, we want to calculate the expected game value and decide if the game is worth playing
Probability of rolling a six is 1/6
Probability of rolling a 5 is 1/6
Probability of rolling a number less than 5 is 4/6 = 2/3
So the only way to win is rolling a six
The expected value is thus;
1/6(3) - 0(1/6) - 2/3(1)
= 1/2 - 2/3
= -$0.17
Since the game gives a negative expected value, it is not favorable and should not be played
1) y=mx+b
m=slope
m=-3/7 in y=-3/7x+20
2) Since the slope is negative it is decreasing, as seen on a graph. So, the tire tread would be decreasing by the month (x).
3) y=mx+b
b=y-intercept
b=20 in y=-3/7x+20
