First draw p yellow = 4/7
2nd draw p red = 3/7
3rd draw p red = 3/7

To find the probability of this event (1yellow 2 red - with replacement) we multiply the probabilities.

4/7 x 3/7 x3/7  = 36/343 which cannot be reduced further

There are 7 marbles in the bowl all together.

-- Probability of a yellow marble on any draw  =  4/7
-- Probability of a red marble on any draw       =  3/7

-- Probability of one yellow and two red in 3 draws = (4/7) (3/7) (3/7) = <u>36/343</u>

                                                                                     =    <em>10.5%  </em>(rounded)

Find the measure of angle A. (Hint: You will need to find the value of x, but that is NOT the solution.)
dangina [55]

Answer:

41°

Step-by-step explanation:

Sum of angle measures in a triangle: 180°

So,

108 + x + 5 + x - 5 = 180

Simplify.

2x + 108 = 180

Subtract 108 from both sides.

2x = 72

x = 36

Substitute x = 36 into (x + 5)

m∠A = 36 + 5 = 41

Thus, the answer is 41°
