What is the amount of oil for a sports car? 5 gallons, 5 quarts or 5 cups

Option A.

Step-by-step explanation:

We need to find the amount of oil for a sports car.

We know that,

1 quart = 4 cups

1 gallon = 4 quarts = 16 cups

Since, quart and cup are small units and they are not sufficient for a sports car because sports car needs more oil, therefore the amount of oil for a sports car is 5 gallons.

Therefore, the correct option is A.

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
