Answer:
0.384
Step-by-step explanation:
pet supplier has a stock of parakeets of which 20% are blue parakeets
20/100 = 0.2 blue parakeets (success)
1-0.2 = 0.8 not parakeets (not success)
A pet store orders 3 parakeets from this supplier

Answer:
150(10s + h)
Step-by-step explanation:
We need to write an expression for the total items they shipped.
Let each skateboard be s.
Let each helmets be h.
The factory ships 100 boxes with 15 skateboards in each box. That is:
100 * (15 * s) = 1500s
The factory ships 10 boxes with 15 helmets in each box. That is:
10 * (15 * h) = 150h
The total number of items shipped is therefore:
1500s + 150h = 150(10s + h)
This expression represents the total number of items shipped.
