7:45-5:51 gives you the difference in times remember 60sec per min (1:54)
turn it into only seconds so 60+54=114s and 7x60+45=645s
114/645 gives you the percentage of difference
Let's plug in both x and y values in the equation and check if the inequality is true...


Substitute x as 4 and y as 1



- <em>This is not a solution because both are not true, Only one equation is giving true as answer which is not correct!~</em>


Substitute x as 0 and y as -3



- <em>This is a solution because both are true, </em><em>Both the </em><em>equations</em><em> </em><em>are</em><em> </em><em>true</em><em> </em><em>which</em><em> </em><em>means</em><em> </em><em>the</em><em> </em><em>ordered</em><em> </em><em>pair</em><em> </em><em>is</em><em> </em><em>a</em><em> </em><em>solution</em><em>!</em><em>~</em>
<u>Thus</u><u>,</u><u> </u><u>Option</u><u> </u><u>B</u><u> </u><u>(</u><u>0</u><u>,</u><u>-</u><u>3</u><u>)</u><u> </u><u>is</u><u> </u><u>the</u><u> </u><u>correct</u><u> </u><u>choice</u><u>.</u><u>.</u><u>.</u><u>.</u>
Answer:
1) ¼
2) yes
Step-by-step explanation:
1) P(A) = 13/52 = 1/4
P(B) = 4/52 = 1/13
P(A^B) = 1/52
P(A|B) = (1/52) ÷ (1/13) = 1/4
Since P(A|B) = P(A), they are independent
