Answer:
a) rCn = 1176
b) 2352
Step-by-step explanation:
a)Each committee should be formed with 3 members ( no two members could be of the same state) then
Let´s fix a senator for any of the 50 states so in the new condition we need to combined 49 senators in groups of 2 then
rCn = n! / (n - r )! *r!
rCn = 49!/ (49 - 2)!*2!
rCn = 49*48*47! / 47!*2!
rCn = 49*48 /2
rCn = 1176
So we can choose in 1176 different ways a senator for a given state
b) To answer this question we have to note, that, 1176 is the number of ways a committee can be formed with senators of different sate (taking just one senator for state ) if we have 2 senators we need to multiply that figure by 2.
1176*2 = 2352
Answer:
the annual rate of inflation r is 0.023
Step-by-step explanation:
Given by the expression:
The average price of a gallon of milk increased from $0.36 in 1913 to $3.53 in 2013.
Let 
n = 2013 - 1913 = 100
replacing our values into the given equation; then the annual rate of inflation r is as follows:
r = 0.023
Hence, the annual rate of inflation r is 0.023
Yes because linear means lines as to lines become a pair which is an angle.
