<span>W = event where white marble is drawn
B = event where black marble is drawn
The two events W and B are independent. This is because the marble taken out on the first draw is put back into the bag. Since W and B are independent, we can use this rule
P(W and B) = P(w)*P(B)
Use the rule to get
P(W and B) = P(W)*P(B)
P(W and B) = (1/2)*(1/4)
P(W and B) = (1*1)/(2*4)
P(W and B) = 1/8
1/8 is equivalent to 0.125. Use long division or a calculator
0.125 = 12.5% </span>
n=-2 over 1m plus 45. Rise over run is the 2 over one and 10 plus 45 is 55

Answer:
The mean of Martin's scores is 85.2
Step-by-step explanation:
In order to find the mean of a set of numbers, you will have to add up all of the numbers and divide the result by the total numbers in the set.
98 + 78 + 84 + 75 + 91 = 426
Since there are 5 numbers in total, we will do 426 divided by 5.
426 ÷ 5 = 85.2
So, the mean of Martin's scores is 85.2
< x is 90 degrees because triangle ABC is isosceles and AD bisects < BAC.
Triangle BAD is right angled so < y = 90 - <ABD
<ABD = <ACD ( because triangle ABC is isosceles
So < ABD = 47 degrees
Finally y = 90 - 47 = 43 degrees answer
Answer:
The graph for x-2y>=-12 needs to get y aloneso add 2y to both sides to getx >=-12 +2ythen add 12 to both sides of the in equalityx+12 >=2ynext divide each term by 2x/2 + 6 >= yy<= x/2 + 6so the graph connects (0,6) and (2,7) and shade below the solid line
