Answer:
Step-by-step explanation:
Part A
Since, line shown in the graph passes through origin (0, 0), relation between number of quarts picked (Q) and amount of money paid (M) will be proportional.
M ∝ Q
M = kQ [k = proportionality constant]
k = Slope of the line =
Since, line passes through two points (1, 3.5) and (2, 7),
k = = 3.5
Therefore, M = 3.5Q
This relation states that "For each number of quarts picked, $3.5 is to be paid"
Part B
Equation that represents the proportional relation,
y = 3.5x
Or Amount of money paid = 3.5(Number of quarts picked)
Expected number of wins=number of plays times the probability of winning
w=20(14.5/100)
w=20(0.145)
w=2.9
w≈3
So you would expect to win 3 times out of 20 attempts (rounded to the nearest whole number of wins)
Answer:
$9212
Step-by-step explanation:
15000-2250 = 12750 (1st year)
12750-1913 = 10838 (2nd year)
10838-1626 = 9212 ( 3rd year)
