Answer:
The probability that the second card is a face card if it’s known that the first card was a face card is 0.0497
Step-by-step explanation:
Total number of face cards = 12
Total cards = 52
Probability of getting face card on first draw=
Remaining no. of face cards = 11
Remaining number of total cards = 51
Probability of getting face card on second draw=
The probability that the second card is a face card if it’s known that the first card was a face card =
Hence The probability that the second card is a face card if it’s known that the first card was a face card is 0.0497
Answer:
8) No solution
9) n > -5 <em>(View explanation for info on how to graph)</em>
Step-by-step explanation:
<em><u>Question 8</u></em>
<em><u /></em>
<u>24+6k < -6(-4-k)</u> - Solve and graph
1) Distribute -6 to -4 and -k:
24+6k < 24+6k
2) Subtract 6k from both sides:
24<24
^ We know the following is false, therefore there is no solution to question 8.
<em><u>Question 9</u></em>
<em><u /></em>
<u>-2n-40 < 5(6+n)+7n</u> - Solve and graph
1) Distribute 5 to 6 and n:
-2n-40 < 30+5n+7n
2) Combine alike terms:
-2n-40 < 30+12n
3) Add 2n to both sides:
-40 < 30+14n
4) Subtract 30 from both sides:
-70 < 14n
5) Divide both sides by 14:
n > -5
6) To graph, plot an OPEN CIRCLE (<em>don't fill in the circle)</em> at point -5 and then draw an arrow pointing to the right!
Let me know if you need any help with the others :)
A). $2 since on the graph you look at the bottom and the numbers represent the bags of candy. So then you look at the side and see that 2 is the only one plotted to 1
Answer:
Step-by-step explanation:
x is tripled so it becomes 3x
it is decreased by 10 so it becomes 3x - 10
so the answer is <u><em>a) 3x - 10</em></u>
hope this helps
plz mark as brainliest!!!!!!!!!
