Answer:
(2,1)
Step-by-step explanation:
This is the answer by substitution.
change 2x+y=5 to y=5-2x
5x-2(5-2x)=8
x = 2
y=5-2(2)
y = 1
(x,y) = (2,1)
You're welcome!!!
Answer:
23.44%
Step-by-step explanation:
The probability of getting a 4 on the first 2 throws and different numbers on the last 5 throws = 1/6 * 1/6 * (5/6)^5
= 0.01116
There are 7C2 ways of the 2 4's being in different positions
= 7*6 / 2 = 21 ways.
So the required probability = 0.01116 * 21
= 0.2344 or 23.44%.
6,9,8 hope you have a great day :D
