Answer:
18.86 feet
Step-by-step explanation:
One rotation of the tire is equal to the circumference of the tire
The formula for circumference of a circle (remember that a tire is shaped as a circle) = πd
where
π = 22/7
d = diameter
The size of one revolution = 2 x 22/7 = 44/7 feet
The distance covered in one rotation of the tire is 44/7 feet
The distance covered in 3 rotations = (44/7) x 3 = 18.86 feet
20 students.
40% are boys. (40/100)*20 = 0.4 * 20 = 8 boys.
Girls= 20 - 8 = 12 girls.
25% of the boys wear glasses. = (25/100)*8 = 0.25*8 = 2 boys wear glasses.
50% of the girls wear glasses. = (50/100)*12 = 0.50*12 = 6 girls wear glasses.
Total students that wear glasses = 2 + 6 = 8 students.
8 students wear glasses.
Answer: 6,77,040 different random samples of four accounts are possible.
Step-by-step explanation:
We have to calculate the different random samples of four accounts are possible from the population of 65 bank accounts.
we are using combination formula for calculating various combination of four accounts:
= 
Where,
n - total population of bank accounts
r - random samples drawn from the population
= 
= 
= 
= 
= 6,77,040 different random samples of four accounts are possible.
