13/ 52 = 1/4 chances.
There are 13 spades and 52 cards. You divide the spades and cards in the deck to find your chances of drawing one.
You have a 25% chance of getting a spade.
Now you put it back. Since you put it back, you still have the same number of cards and the same number of spades. So when you divide 13/52 again, the numbers are still the same. 1/4. 25% chance.
So, you still have a 25% chance the second time around.
Answer:
2
Step-by-step explanation:
5(2)+2=12
(2)+4=6
5x+2 is twice the length of x+4. Therefore the answer is 2

Step-by-step explanation:
The two ringtones will cost her a total of 
and is a fixed amount. The relationship between the cost and number of songs only is 
and therefore the answer is 
. You can also directly find the answer by finding the y-intercept (in this case 
), as no other answer choices include the term , so A must be the correct answer.
Find a ∩ b if a = {2, 5, 8, 11, 14} and b = {1, 3, 5, 7}. {1, 2, 3, 5, 7, 8, 11, 14} {5}

The intersection of given set a and b is a∩b = {5}.
According to the given question.
We have two sets a and b.
a = {2, 5, 8, 11, 14}
And, b = {1, 3, 5, 7}
As, we know that "the intersection of two sets A and B is the set of all those elements which are common to both A and B. Symbolically, we can represent the intersection of A and B as A ∩ B".
Since, only the element which is common to set a and set b is 5.
Thereofore, the intersection of given set a and b is given by
a∩b = {5}
