Answer - Andrea is NOT correct.
I can explain it best by suggesting both Andrea and Blake start with 10 marbles.
If Andrea gave one (1) marble to Blake, Andrea now has 9 and Blake has 11.
Step-by-step explanation:
Below is an attachment containing the solution.
Answer:A. The theoretical probability for pink is 95/185 or about 51.35%
B. The theoretical probability for brown is 90/185 or about 47.82%.
C. To find the experimental probability, we will make another fraction. The number of outcomes will be the numerator and the total will be the denominator.
Pink 36/69 = 52.17%
Brown 33/69 = 47.82%
Step-by-step explanation:
sin x = cos 54 = sin (90-54) = sin 46
Hence x = 46 deg
Same technique. Sin 21 = cos (5x+9) = sin (90-5x-9)
81-5x = 21
Or 5x = 60
Or x = 12 deg
hope it helps
Answer:
12°
55°
Step-by-step explanation:
∠WXY=90°
∠ZXY=∠WXY- ∠WXZ= 90° - 35°= 55°
- 4x+7°= 55°
- 4x= 48°
- x= 48°/4
- x= 12°
