Answer:
=
Step-by-step explanation:
Total Number of Cards=52
Number of Cards having a point value of 10=16
Number of Aces=4
We want to determine the probability that both cards dealt are aces or 10-point cards.
P(Aces) =
P(10 point cards)=
Definition
If A and B are mutually exclusive events,
Probability (A OR B) = P(A)+P(B)
P(both cards dealt are aces or 10-point cards) = P(Aces) + P(10 point cards)
=
=
Answer: 146cm²
Step-by-step explanation:
Answer:
33 by 45 meters
Step-by-step explanation:
The perimeter is twice the sum of adjacent side lengths, so the sum of the dimensions is 78 meters. If x is one of the dimensions, then 78-x is the other, and the area is their product:
x(78 -x) = 1485
Subtracting the left side, we get ...
x^2 -78x +1485 = 0
This can be graphed as ...
y = x^2 -78x +1485
and the zeros will reveal the dimensions.
The attached graph shows them to be ...
33 by 45 meters
The answer is 843... if you are talking about adding...
