The miles that can be travelled in the car on $30 gasoline is 240 miles (option A).
<h3>How many miles can the car travel?</h3>
The first step is to determine the total gallons in the car. The total gallons in the car can be determined by dividing the total value of the gasoline the car by the cost per gallon. Division is the process of determining the quotient of two or more numbers.
Total gallons = total value of gasoline in the car / cost per gallon
$30 / $2.50 = 12 gallons
The next step is to determine the total miles that the car can travel using the gallons available. To determine the total miles, multiply the total gallons by the number of miles that that one gallon can cover.
Total miles = miles one gallon can cover x total gallons in the car
12 x 20 = 240 miles

Answer:
a. 5 hours
b. 40 kph
Step-by-step explanation:
300 km ÷ 60 km = 5 hours
200 km ÷ 5 hours = 40 kilometers per hour
Answer: A 50% chance or 1/2 chance for each.
Step-by-step explanation: You did not state how many sides are on the die, but I am going to assume a standard 6 sided die in my answer. You stated 3 numbers (4, 5, and 1) and 3 numbers on a 6 sided die are 1/2 or a 50% chance.
The volume of the spherical solid resulting of the drill is of 11,226 units³.
<h3>What is the volume of a sphere?</h3>
The volume of a sphere of radius r is given as follows:
In this problem, we have two spherical balls, one of radius 14 and other of radius 4, hence their volumes are given as follows:
The volume of the resulting solid is the difference of the volumes, hence:
V = 11494 - 268 = 11,226 units³.

The parameter used in the probability is the average number of students represented by u.
How to calculate the probability?
The confidence interval based on the information will be:
= 3.85 - 2.09(1.348 / ✓20)
= 3.22
Also, 3.85 + 2.09(1.348 / ✓20) = 4.48
The confidence interval simply means that one is 95% confident that the true mean is between 3.22 and 4.48.
