Answer:let x be the number of cars, and 7-x be the number of trucks.
25x + 30(7-x) = 195
25x + 210-30x = 195
5x = 15
x = 3
So, 3 cars were not rented. If 7 total vehicles were not rented, 7 - 3 cars = 4 Trucks
4 Trucks were not rented.
Step-by-step explanation:

Step-by-step explanation:
The decay function for percentage decay is given by:

Here,
a is the initial value
r is the rate
x is the number of time periods
Given
Initial value = 100 grams
Rate = 6% = 0.06
Time = 1 year = 52 weeks
Putting the values in the formula

Hence,
4 grams sample will be left after 1 year

Answer:
Step-by-step explanation:
Probability is the occurrence of any event it lies between 0 and 1
If there is 100 % chance to occur any event then probability is 1 and if there is no chance to occur any event then probability is 0
Probability is given by 
As the total outcomes is always greater than favorable outcomes so probability will be always less than 1 and it can't be negative so greater than zero.
