Choice A. <span>14/81
</span>Possible outcomes = total number of marbles = 18
P (1st blue) = 8/18 = 4/9
P (2nd red with replacement of blue) = 7/18
P (both) = (4/9) * (7/18) = 28/162 = 14/81
Choice B. 7/18
Possible outcomes = total number of marbles = 18
<span>P (1st black) = 3/18 = 1/6 </span>
<span>P (2nd red with replacement of black) = 7/18 </span>
<span>P (both) = (1/6) * (7/18) = 7/108</span>
Answer:
A) 129° B)66°
Step-by-step explanation:
A) A is 129° because the angle is alternate to it.
B) B is 66° because it the angle you would be trying to find would be alternate to that angle, however we do not yet have the angle. To find this angle, we will need to do 180-114 as angles on straight lines add up to 180°. 180-144 is subsequently 66°.

The formula is Area = ( top + bottom)/2 * height
Using the image:
Area = (20 + 14) / 2 * 9
Area = 34/2 * 9
Area = 17*9
Area = 153 cm^2
