Answer:
Step-by-step explanation:
What is the probability that when two cards are drawn from a deck of cards without
replacement that both of them will be 8’s?
(ℎ 8
′
) = ( 8) ∙ ( 8)
( 8) =
4
52
There are three 8’s left in the deck if one is pulled and not replaced, and 51 total
cards remaining.
( 8) =
3
51
(ℎ 8
′
) =
4
52 ∙
3
51 =
12
2652 =
1
221 = .0045 .45%
Answer:
<h2>$12.6</h2>
Step-by-step explanation:
Step one:
given that the dimensions are
length=3cm
width=4cm
hieght= 7cm
the volume of the pool is= lwh
volume=3*4*7= 84cm^3
Step two:
the cost of filling
we are told that 1cm^3 will cost $0.15
hence 84cm^3 will cost x
cross multiply
x= 0.15*84
x=12.6
<u>The cost of filling the pool will be $12.6</u>
Answer:
the reasoning states that "all the numbers begin with a 7 or an 8"
however this is not accurate as they can be in different placements
which can make a big difference in the total estimate.
for example:
the number could've been an 8, or an 80
they both begin with an 8
however have totally different values and could have messed up the total estimated number.
hope this helps :D
<span>8/6 = x + 2/32
To solve this, you need to subtract 2/32 from both sides. To do that though, the two fractions need to have a common denominator.
2/32 can be simplified to 1/16.
The lowest denominator they have in common is 48.
1/16 = 3/48
8/6 = 64/48
Now subtract them.
</span>(64/48) - (3/48) = 61/48
That cannot be simplified, so it's the final answer.
x = 61/48
