Answer:
Deon drove the truck 201 miles.
Step-by-step explanation:
Base Fee + (.98* Number of miles)= Cost
19.99 + .98x = 216.97
Subtract 19.99 from both sides.
.98x = 196.98
Divide both sides by .98
x = 201
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
we need to find the chance of getting exactly one blue from 3 parakeets
n=3, r=1, p = 0.2 , q=0.8
0.384
Y=20x -1500, y equals the prophet, x is the number of books, 20 is the money made after taking out the cost of production, 1500 is a cost that only occurs once.
Take out the constants
(2 × 4)x^2xx^2y^3y^4z^2
Simplify 2 × 4 to 8
8x^2xx^2y^3y^4z^2
Use the Product Rule: x^ax^b = x^a + b
8x^2 + 1 + 2y^3 + 4z^2
Simplify 2 + 1 + 2 to 5
8x^5y^3 + 4z^2
Simplify 3 + 4 to 7
<u>8x^5y^7z^2</u>
