Answer:
Total distance Jason cycled = 20 miles
Step-by-step explanation:
Distance covered in first 2 hours = 2( 7.5)
=15
Distance covered in the 3rd hour = 15/3
= 5
Dividing by 3 because the distance covered in the 3rd hour is 1/4 of the distance covered in first two hours. By dividing by 3 we will get 1/4 of the distance
Total Distance = Distance covered in first two hours
+ Distance covered in the 3rd hour
=15 + 5
Total Distance = 20
Answer:
P (She selects the route of four specific capitals) = 
D. No,it is not practical to list all of the different possible routes because the number of possible permutations is very large.
Step-by-step explanation:
Let's start assuming that each route is equally likely to be chosen.
Assuming this, we can calculate P(A) where the event A is ''She selects the route of four specific capitals'' doing the following :
P(A) = Favourable cases in which the route of four specific capitals is selected / Total number of ways in 4 of 42 states
The favourable cases in which the route of four specific capitals is selected is equal to 1 .
For the denominator we need the permutation number of 4 in 42.
The permutation number is defined as :


The probability of event A is : 
Finally for the other question : The option D is the correct because the number of possible permutations is 2686320 and is very large to be listed.
Answer:
25
Step-by-step explanation:
4.5×5.5=24.75
so 24.75 is the area of the room but you have to buy whole tiles so you would need to but 25 tiles
535 centimeters because of the decimal places
Answer: -3
