X=84° because the 84 above it and x are corresponding angles
Probability of giving birth to four consecutive boys ;
0.52 0.52 * 0.52 * 0.52
= 0.073 ( rounded off)
Thus, the probability to give birth to 4 consecutive boys is 0.073
Answer:
10
4
Step-by-step explanation:
Purple: This makes two trapezoids. A=(a+b)/2 times h
1st = (4+1)/2 x 1 = 2.5
2nd = (4+1)/2 x 3 = 5/2 x 3 = 2.5x3=7.5
Total = 2.5+7.5=10
Green: if you draw a line down the center, you can divide these into two more manageable triangles. A=1/2bh
1st = 1/2x2x2 = 2
2nd = 1/2x2x2 = 2
Total = 2+2=4
The answer is 61.
66 + 7 = 73
13 + 8 = 21
52 + 9 = 61 (The answer)
10 + 10 = 20
