Answer:
a) 12/52 = 3/14
b) 26/52 = 1/2
c) 4/52 = 1/13
d) 13/52 = 1/4
e) 8/52 = 2/13
Step-by-step explanation:
a) there are 12 face cards and 52 in the deck
b) half the cards are red, the other half black
c) one queen in each of four suits
d) the deck is broken up into 4 equal suits (hearts, diamonds, spades, clubs) so there are 13 of each.
e) like the answer in part C, there is one of each card in each of the four suits. that gives us four aces and four tens.
I think it’s “impossible”
Answer:
x = 10 and x = -10
Step-by-step explanation:
Given the function
This function is undefied when the denominator equals to 0. Find these values for x:
This means that vertical lines x = 10 and x = -10 are vertical asymptotes (the graph of the function f(x) cannot meet these lines because this function is undefined at x = 10 and x = -10)
Answer:
900 degree
Step-by-step explanation:
Answer:
It should be red or green 125 times
Step-by-step explanation:
The first thing to do here is to calculate the probability of selecting a red or a green marble
Total number of marbles = 7 + 3 + 2 + 8 = 20
Probability of selecting a red marble is 7/20
Probability of selecting a green marble is 3/20
The probability of selecting a red or a green marble = Probability of selecting a red marble + Probability of selecting a green marble = 7/20 + 3/20 = 10/20 = 1/2
Now our selection spans 250 times, the number of times it should have been a green or a red marble = The probability of selecting a green or a red marble * number of selection times = 1/2 * 250 = 125 times
