Mail order cost for n prints will be
m = 0.40n +1.15
Photo shop cost for n prints will be
p = 0.52n
Mail order cost will be less than photo shop cost when
m < p
0.40n +1.15 < 0.52n
1.15 < 0.12n
9.583 < n
A customer must purchase 10 or more prints to make it less expensive to use mail order.
Answer:
independent events
Step-by-step explanation:
dependent is when the previous event affects the outcome of the next event.
Ex: When I draw a card without replacement at first I will have 52 cards. Once I draw the card, I will have only 51 cards to choose from.
Independent event is when the outcome is not related.

Answer:
Step-by-step explanation:
we have
Find the inverse
Let
y=f(x)
Exchange the variables (x for y and y for x)
Isolate he variable y
subtract 12 both sides
divide by 4 both sides
Let
g(x)=y
---> inverse of the function f(x)
X=110°
y=30°
Assuming that this is a parallelogram, ∠y and the 30° angle in the top right would be congruent, as would ∠x and the 110° angle in the bottom right.
They all should add up to 360°
110+110+30+30+40+40=360
which they do...
