Answer:
6 / 51
Step-by-step explanation:
It is false.
Reason:
The probability of picking a black card at first is:
26 / 52 = 1/2
There are now 25 black cards and 51 cards in total.
The probability of picking another black card, if there's no replacement is now:
25 / 51
Now, there are 24 black cards and 50 cards left in total.
The probability of picking a black card without replacement now becomes:
24 / 50 = 12 / 25
Hence, the probability of picking three black cards without replacement is:
1/2 * 25/51 * 12 / 25 = 300 / 2550
In simplest form, it is 6 / 51
Answer:the first one on the left, where 8 and under is at the 45 players, non of the others match up

Answer:
C. 90
Step-by-step explanation:
If x^3 = 729, x = 9.
Then, plug that into x^2 + x
9 ^ 2 + 9 = 81 + 9 = 90
N = 30 makes that a perfect square
Answer:
x = 2.2
Step-by-step explanation:
From the figure, we see that
Δ ABC
is similar to
Δ ADE
So we can say that the corresponding sides are proportional (ratio is equal).
From the similarity statement, we can say:
AB corresponds to AD
BC corresponds to DE
AB = 10
AD = 10 + 1 = 11
BC = 2
DE = x
Now, we can write ratios and solve:
The value of x is 2.2
