Answer:
Letters can be chosen in 12 different ways, if order matters, or 6 different ways, if order doesn't matter.
Step-by-step explanation:
Since we want to choose 2 letters, without replacement, from the 4 letters A, B, C, and D, to determine in how many ways can this be done, if the order of the choices matters, and in how many ways can this be done, if the order of the choices does not matter, the following calculations must be performed:
If order matters =
(4 x 3 x 2 x 1) / 2 = X
24/2 = X
12 = X
If the order doesn't matter =
12/2 = X
6 = X
Therefore, letters can be chosen in 12 different ways, if order matters, or 6 different ways, if order doesn't matter.

Answer:
c. Multiple zero is 3; multiplicity is 2
Step-by-step explanation:
The factor is repeated, that is, the factor (
x − 3
) appears twice. The number of times a given factor appears in the factored form of the equation of a polynomial is called the multiplicity. The zero associated with this factor, x = 3
, has multiplicity 2 because the factor (
x − 3
) occurs twice.
Then
Multiple zero is 3; multiplicity is 2.
Answer:
$2.60 per towel
Step-by-step explanation:
15.60 devided by 6 =2.60
Answer:
$700
Step-by-step explanation:
Step one:
Given data
Regular cost of cell phone= $780
discount = 15%
tax = 5.5%
Step two
Let us compute the discounted amount
= 15/100*780
=0.15*780
=$117
hence the selling price is
=780-117
=$663
Also, the tax-deductible is
=5.5/100*663
=0.055*663
=$36.465
The total cost of the phone will be
=663+36.465
=699.465
=$700 to the nearest cent
