1 answer:
frosja888 [35]3 years ago

Answer:

1. No, 2. 46, 3. The amount of tails flips would be more than the amount of heads flips.

Step-by-step explanation:

1 is no because .77 and .23 are not equal to .5, so her prediction was wrong. 2 is 46 because if you double both the numbers (to get a total of 200 flips), you would get 154 tails and 46 heads. 3 is more tails than heads because that is what we have observed.

statuscvo [17]

Answer:a) 54/55

b) 100/110

c) 99/110

Step-by-step explanation:

a)Probability of ordering 4= 9/12×3/11×2/10×1/9 = 54/11880

Probability of 4 good units= 4 × 54/11880

= 216/11880

1/55

1-(1/55) = 54/55

b)Probability of 2 good units= 2 × 54/(11880)

= 108/11880

= 1/110

1- (1/110)= 100/110

c) Probability of exactly 2 units not good= 1 -(100/110) =99/110

Aneli [31]

diagonal = sqrt(l^ + w^2)

17 = sqrt(10^2 + x^2)

17^2 = 10^2 + x^2

289 = 100 + x^2

189 = x^2

x = sqrt(189) = 13.747

X = 13.75

 width is 13.75 inches
