ou are assembling a loft. One piece of wood has 9 screw holes in a straight row, but you can only find 7 screws (which look iden
Katyanochek1 [597]

Answer:

1) If the order doesn't matter, there are 36 possible outcomes.

2) If the order does matter, there are 181,440 possible outcomes.

Step-by-step explanation:

1) In the case when the order doesn't matter , we have to calculate a combination of 7 screws in 9 holes.

We use the formula for combinations:

C=\frac{n!}{(n-r))!r!} =\frac{9!}{2!7!}=\frac{362880}{2*5040}=36

being r: the number of screws and n: the number of holes.

2) When the order does matter, the possible outcomes are called permutations. We have permutations of 7 screws in 9 holes.

We use the formula for permutations:

P=\frac{n!}{(n-r)!}=\frac{9!}{(9-7)!}=\frac{362880}{2}=181,440

Answer:

(2, 5)

Step-by-step explanation:

Let the number of fancy throw pillows be x.

Let the number of plain throw pillows be y.

Hope spent a total of $131 on 7 throw pillows.

Fancy throw pillows  cost $28 and plain throw pillows cost $15.

These imply two things:

x + y = 7 _______  (1)

28x + 15y = 131 ___(2)

We have a linear system of equations.

From (1):

x = 7 - y

Substitute the value of f into (2):

28(7 - y) + 15y = 131

196 - 28y + 15y = 131

196 - 13y = 131

=> 13y = 196 - 131

13y = 65

y = 65 / 13

y = 5

This means that:

x = 7 - 5 = 2

Hope bought 2 fancy throw pillows and 5 plain throw pillows

Vaselesa [24]
Well, since it is asking for an average, we have to add
78+89+87+96=
350... then we divide by 4
which would be 87.5 which IS greater than 80 :)
and less than 90 :)
