Answer:
McDonald’s hamburger has a greater volume, compared to Wendy’s hamburger.
McDonald’s hamburger is 0.5 cubic Inch bigger.
Step-by-step explanation:
Volume of square burger = 4 * 4 * 3/16 = 3 cubic Inch
Area of the circular hamburger:
pi * diameter
Volume of the circular hamburger =
pi * diameter * thickness
pi * 4.5 * 1/4 = 3.53429173528852 cubic Inch
rounded answer is 3.5 cubic
McDonald’s circular hamburger has a greater volume, compared to Wendy’s hamburger, a bit more then 0.5 cubic Inch bigger.
Answer:
B' (2, 5 )
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 270°
a point (x, y ) → (y, - x ) , then
B(- 5, 2 ) → B' (2, 5 )
Answer:
The center of circle is
Step-by-step explanation:
We need to find the center of the circle of the equation 
Since, the general equation of circle is 
Where (h,k) is center of circle and r is radius.
Re-write the circle equation is
as,

Compare
with 
so, 
Hence, the center of circle is 
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

a) Probability that exactly 3 people have same birthday = 
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 = 
Expected value of days = np = 
b) Distinct birthdays is binomail with p =1/365 and n = 365
Hence
expected value = np =1
