Yes because if you graph it, it will pass the vertical line test
16cos(28). Type that in like last time.
$9147 x 12 =190,764
12 is how many months there is in a year
Answer:
Step-by-step explanation:
Leaving leap years, a year contains 365 days.
For a group of 100 people, each person is independent of the other and probability of any day being his birthday has a chance of
![\frac{1}{365}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B365%7D)
a) Probability that exactly 3 people have same birthday = ![\frac{1}{365^3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B365%5E3%7D)
Each day is independent of the other
And hence no of days having exactly 3 persons birthday out of 100 persons is binomial with n = 365 and p = ![\frac{1}{365^3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B365%5E3%7D)
Expected value of days = np = ![\frac{1}{365^2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B365%5E2%7D)
b) Distinct birthdays is binomail with p =1/365 and n = 365
Hence
expected value = np =1
1 hour=3600 seconds
1 mile=5280 feet
87 miles/hr (1 hr/3600 sec)(5280 ft/mile)=127.6 feet/sec
Distance= Rate*time
d=127.6(12)=1531.2 feet (after 12 seconds)
