List all the different combinations with total cost:
Airplane + van = 350 + 60 = $410
Airplane + cab = 350 + 40 = $390
Bus + van = 150 + 60 = $210
Bus + cab = 150 + 40 = $190
Train + van = 225 + 60 = $285
Train + cab = 225 + 40 = $265
There are 6 different combinations.
There are 2 that are more than $300
The probability would be quantity higher than 300 / total combinations.
Probability = 2/6 = 1/3
So,
0.2(n - 6) = 2.8
Distribute.
0.2n - 1.2 = 2.8
Add 1.2 to both sides.
0.2n = 4
Divide both sides by .2.
n = 20
Check.
0.2(20 - 6) = 2.8
Simplify inside parentheses.
0.2(14) = 2.8
Multiply.
2.8 = 2.8 This checks.
S = {2.8}

Step-by-step explanation:
The area of a large pizza cut into 10 slices with be 20 square inches. This is from taking the area of a large 200.96 and dividing by 10.

Answer:
1.28 minutes
Step-by-step explanation:
Given data
Speed= 7 meters per minute
Distance= 8.96 meters
We know that the expression for the Speed, Distance, and time is given as
Speed= Distance/Time
TIme= Distance/Speed
Substitute
Time= 8.96/7
Time= 1.28 minutes
