Answer:
The cost of a small bag of popcorn is
The cost of a large bag of popcorn is
Step-by-step explanation:
Let
x----> the cost of a small bag of popcorn
y----> the cost of a large bag of popcorn
we know that
----> equation A
----> equation B
Solve the system of equations by graphing
Remember that the solution of the system of equations is the intersection point both graphs
The solution is the point (2.95,4.75)
see the attached figure
therefore
The cost of a small bag of popcorn is
The cost of a large bag of popcorn is

Answer: (2, 12)</h3>
=================================
Explanation:
The translation rule is T(x,y) = (x-5, y+10) meaning we shift P 5 units to the left and 10 units up to go from P(2,-4) to P ' (-3, 6)
x = 2 ---> x-5 = 2-5 = -3
y = -4 ---> y+10 = -4+10 = 6
Apply the same idea to the point (7,2) to get the following two values
x = 7 ----> x-5 = 7-5 = 2
y = 2 ---> y+10 = 2+10 = 12
Answer:
Mean = 24
Variance = 107.78
Standard deviation = 10.38
Hope this helps! :)
