Answer:
So the best option is c) 0.1912
Step-by-step explanation:
For this case we have a standard deck of 52 cards and we consider the experiment without replacement.
So then we have 13 heart cards and 52-13 = 39 NOT heart cards
In order to find the probability that we select a heart card in the first extraction we have this:
Now for the second extraction we have a total of 51 cards since we select one at the first extraction and we can find the probability of not heart like this:
And for this case we can assume that we have independent events since the extraction of the first and second card are not related events and assuming this we have this probability:
So the best option is c) 0.1912
Answer:
total area = 217 m³
Step-by-step explanation:
area of the triangle
= 14 × 10
= 140 m²
area of a semicircle
= 1/2 × 22/7 × 7 × 7
= 77 m²
total area
= 140 + 77
= 217 m³
Answer:
s^4/r^2
Step-by-step explanation:
r^-2/ s^-4
When the exponent is negative, it moves from the numerator to the denominator or from the denominator to the numerator
r^-2 becomes 1 /r^2
1 / s^-4 becomes s^4
r^-2/ s^-4 = s^4/r^2
Actually an infinite number. Since y or x can be anything, that is infinity.
