Answer: 1/4
Step-by-step explanation:
To determine the probability of landing on blue, you divide by the total number of spins.
In this experiment, the probability of the spinner landing on blue after 20 spins would be 15%.
This makes the probability of landing on blue to be:
Pr (landing on blue) / Pr (total trials) = 5/20
This gives 1/4
Answer:

Answer:
A) 40 + d
B) 45 days
Step-by-step explanation:
A)
total cost = (cost of the air conditioner itself) + (money charged per day)*(days)
cost of air conditioner itself = $40
money charged per day = $1
days = d
40 + 1*d
= 40 + d
B)
total cost = 40 + d
total cost = $85
85 = 40 + d
45 = d
Time used the air conditioner for 45 days.
