there are two coins, one fair and one biased. The biased coin comes up heads with a probability of 0.8 and tails with a probability 0.2. One of the coins is selected at random and flipped ten times. The results of the coin flips are mutually independent. The result of the 10 flips is

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°

step-by-step explanation:

5 + 8 +7 + 4 + 0 +1 = 25
