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

Step-by-step explanation:
Answer:
y = 1/8x
Step-by-step explanation:
<h3>REMEBER: When the slopes are two lines are equal, they're parallel.</h3>
Given Equation:
- x - 8y = 48 ---> This equation is in standard form.
⇒ -8y = -1x + 48
⇒ y = 1/8x + 6
As a result, the equation of the parallal line to the given equation x - 8y = 48 is:
⇒ y = 1/8x
