Answer:
$5 per ticket
Step-by-step explanation:
25/5 = 5
Answer:
20ln(3)
Step-by-step explanation:
Put 15 for A and solve for t.
15 = 45e^(-.05t)
15/45 = 1/3 = e^(-.05t) . . . . divide by 45
ln(1/3) = -.05t . . . . . . . . . . . take natural logs
20ln(3) = t . . . . . . . . . . . . . . multiply by 20, simplify
It will take 20·ln(3) years for the area to decrease to 15 km^2.
Answer:
1/3
Step-by-step explanation:
The total number of marbles is
6+12 = 18
P( red) = red/total
= 6/18
=1/3
F(x) = x3 - 5x2 - 2x + 24
roots -2, 3 and 4
Answer:
P(compact cars) = 4/25
Step-by-step explanation:
We know that there are 13 trucks, 8 vans, and 4 compact cars.
Let P denotes the probability of an event
Now we are asked to find the probability of compact cars
Number of favorable events = number of compact cars = 4
total number of outcomes = 13+8+4 = 25
hence, P(compact cars) = number of favorable events/total outcomes
=4/25
