Ten cards numbered 1 through 10 are mixed together and then one card is drawn. What is the

1 answer:

3 0

Chance of a 2: 1/10. Chance of a 3: 1/10. These are disjoint events (they can’t happen at the same time) but we need the probability that either can happen. So 1/10+1/10=2/10=1/5.
This intuitively makes sense since there are 2 numbers out 10

Width = w
Length = 2w
Height = 4w
$w \times 2w = 384 \\ {2w}^{2} = 384 \\ {w}^{2} = 192 \\ w = 13.86cm$
Width = 13.86cm

Use substitution to solve the system. x=3y-8 3x-4y=-9

nadya68 [22]

x=3y-8
3x-4y=-9

We are told that:
x=3y-8

So replace x in 3x-4y=-9 with x=3y-8 like so:
3(3y-8)-4y=-9

Start by distributing the 3:
$(3)(3y)+(3)(-8)+-4y=-9$
Now you have:
$9y+-24+-4y=-9
$
Combine like terms, now you have:
$5y-24=-9
$
add 24 to both sides
$5y-24+24=-9+24
$
Now you have:
$5y=15$
Divide both sides by 5 to get:
y=3

Now that you know y=3 plug it into:
x=3y-8
x=3(3)-8
x=1

Final answer:
(1,3)
