A pet store sells mice reptiles and birds Let event A = a customer buys a mouse Let event B = A customer buys a reptile What doe
enyata [817]

Answer:

The correct option is C.

Step-by-step explanation:

According to the question given in the attached picture:

Event A = a customer buys a mouse

Event B = A customer buys a bird

P(A or B) = 0.25

Now have a look at the probability P(A or B). Here or means either..Its means that the customer will purchase either a mouse or a bird. That means that there is 0.25 or 25% probability that the customer will purchase either a mouse or a bird. In this case there are only 3 choices, which are: the customer will either purchase a mouse, a bird or a reptile because the pet store has only these three possible outcomes. We are not told that how much of each animal they have. Thus the probability that the customer will either purchase either a mouse or a bird is  0.25 or 25%. That means that the probability of either purchasing a mouse or a bird is added together which is 0.25 or 25%

Thus the correct option is C....

klemol [59]
For this case we first define varials:
 x: number of hours working as cashier
 y: number of hours working as a baby sit
 We now write the system of equations:
 6x + 6y ≥ 60
 x + y ≤ 12
 Answer:
 
to solve the real-world problem the system of inequalities is:
 
6x + 6y ≥ 60
 
x + y ≤ 12

Use synthetic division to find the expression for the area of the base of a rectangular prism with height x 4 and volume x3 2x2
IRINA_888 [86]

The expression for the area of the base of Prism is   x2 – 2x – 9

The volume of a rectangular prism is this

Volume = Area x Height

Substituting the given expressions

x3 + 2x2 - 17x - 36 = Area x (x + 4)

Area = (x3 + 2x2 - 17x - 36) / (x + 4)

Now, let's use synthetic division

-4 |    1    2    -17   -36

----    __-4___8___36

        1    -2     -9     0

The expression for the area is

Area = x2 - 2x - 9
