Step-by-step explanation:
There are 20 chips in total.
P(red) = 8/20 = 2/5
P(not green) = 16/20 = 4/5
P(yellow or green) = 9/20
Answer:
Option D (r(t) = 3.50t +25
; r(8) = 53)
Step-by-step explanation:
The fixed cost to rent the kayak $25. This is the cost which remains fixed irrespective of the usage of the kayak. The variable cost of using the kayak is the cost which depends on the usage of the kayak. It is mentioned that the kayak is used for 4 hours and the company charges $3.5 for every half hour. The cost function is given by:
r(t) = 25 + 3.5t ; there r is the total cost of using the kayak and t is the number of half-hours the kayak is used.
4 hours means that there are 8 half-hours. Therefore, t=8. Put t=8 in r(t).
r(8) = 25 + 3.5*(8) = 25 + 28 = 53.
Therefore, Option D is the correct answer!!!
Answer:
Step-by-step explanation:
By the diagram FG = MN.
3y + 3 = 5y - 25 Add 25 to both sides
3y + 3 + 25 = 5y Subtract 3y from both sides
28 = 5y - 3y Combine
28 = 2y Divide by 2
28/2 = 2y/2
y = 15
15 is not your answer. It is just the value of y.
3y + 3 = 3*15 + 3 = 45 + 3 = 48
There are 3 face cards for each of the 4 suits, leading to a total possible gain of 120, there are 40 other cards leading to a total possible loss of 80.
120 - 80 = 40.
40 / 52 (total number of cards) = about .77
Final Answer:
The expected value of a draw is positive 0.77 points.
