5 0

Answer: it could end in 20 different ways.

Step-by-step explanation:

This match could be

3x0 D or F

3x1 D or F

3x2 D or F

For 3x0

We have 2 options: DDD or FFF

2.P₁ = 2.1 = 2

For 3x1

We have 6 options

DFDD         FDFF

DDFD         FFDF    

FDDD         DFFF

2.3.1 = 6

For 3x2

we have 12 options:

DFDFD          FDFDF

DDFFD          FFDDF

DFFDD          FDDFF

FFDDD          DDFFF

FDFDD          DFDFF

FDDFD          DFFDF

2.3.2 = 12

In total we could have 20 outcomes.

if a 16 ounce nectar feeder concede about 80 hummingbirds a day how many hummingbirds would you expect to be able to feed with a
tekilochka [14]
In the given question, it is already given that the 16 ounce feeder can feed about 80 humming birds. It has to be found the number of birds that a 12 ounce feeder can feed.
Now coming back to the problem.
The number of humming birds that a 16 ounce feeder can feed = 80
The number of humming birds that 1 ounce feeder can feed = (80/16) * 1
                                                                                                 = 5 * 1
                                                                                                 = 5 birds
Then
The number of humming birds that a 12 ounce feeder can feed = (12 * 5) birds
                                                                                                       = 60 birds
So a 12 ounce feeder can feed 60 humming birds.

Solve for b.<br> 3-2(b-2)=2-7b3−2(b−2)=2−7b
lyudmila [28]

Step-by-step explanation:

3 - 2(b - 2) = 2 - 7b

To solve this first distribute -2 to (b - 2)

3 + (-2b + (-2) x -2) = 2 - 7b

when we simplify this it becomes:

3 + (-2b + 4) = 2 - 7b

We take (-2b + 4) out of the parenthesis:

3 - 2b + 4 = 2 - 7b

Now simplify again.

7 - 2b = 2 - 7b

Now send all the b's to one side and constants on the other.

7 - 2 = -7b +2b

5 = 5b

b = 1
