It take 23 mins for the drive
He needs to reach the airport by a quarter before 6
a quarter before 6 = 5.45
So he needs to leave 23 mins before 5.45
23 mins before 5.45 = 5.22
> is greater than
< is less than
Answer:
3/4
Step-by-step explanation:
A: students present
B: students on time
P(all students present and on time) = P(A and B) = 3/10
P(all students present) = P(A) = 2/5
P(A and B) = P(A).P(B|A) where P(B|A) is the probability of everyone being on time given that everyone is present
So P(B|A) = P(A and B) /P(A) = 3/10 ÷ 2/5 = 3/10 * 5/2 = 15/20 which can be reduced to 3/4 by dividing numerator and denominator by 5
Circunference=diameter time pi
aprox pi to 3.14
circunference=200.332
subsitue
200.332=diameter time s3.14
divide both sides by 3.14
63.8=diameter
answer is 63.8 units
Answer:
mean = $11.15
median = $11.30
mode = $9.90, $10.70, $11.90, $12.05
Step-by-step explanation:
Ordered from smallest to largest
9.89, 10.71, 11.90, 12.06
The mean is the middle number.
There are two numbers in the middle so you have to add them together and divide by 2.
(10.71 + 11.90)/2 = 11.305
rounded 11.30
Mode is the number that appears the most. All of the prices are listed once. They are all the mode.
Mean is (10.71+11.90+9.89+12.06)/4 = 11.14
round 11.15
