Answer:
56 times
Step-by-step explanation:
P(red & red) = 0.5×0.6 = 0.3
Expected no. = no. Of trials × p
No. of trials: 84/0.3 = 280
P(blue & blue) = 0.5×0.4 = 0.2
Expected no. = 280 × 0.2
= 56

Answer:
11.6666666667
Step-by-step explanation:
First you multiply 7 by 5
7x5=35
Then you divide 35 by 3
35/3 = 11.6666666667
Long leg = 8 → opposite
short leg = 6 → adjacent
hypotenuse = ?
8² + 6² = c²
64 + 36 = c²
100 = c²
√100 = √c²
10 = c
sin ∠BOC = opposite / hypotenuse
sin ∠BOC = 8 / 10
sin ∠BOC = 0.80
tan ∠BOC = opposite / adjacent
tan ∠BOC = 8 / 6
tan ∠BOC = 1.33
