Answer:
11/1024.
Step-by-step explanation:
Binomial Probability distribution.
This is the probability of 9 tails or 10 tails being flipped.
Prob ( 10 tails) = (1/2)^10 = 1/1024
Prob ( 9 tails) = 10C9 * 1/2^9* 1/2 = 5/512
Required probability = 1/1024 + 5/512
= 11/1024.
Answer:
32 people got off
Step-by-step explanation:For the 10th stop, we can get the total number of people that have gotten off
Mathematically, this is the product of the mean and the number of stops
= 10 * 6.3 = 63 people
Now, for the 11th stop, the total becomes
11 * 8.6 = 94.6
Answer:
3d + 15
Step-by-step explanation:
(d + 5) + (d + 5) + (d + 5) =
d + 5 + d + 5 + d + 5 =
(d + d + d) + (5 + 5 + 5) =
3d + 15
Answer:
(a)
(b)
Step-by-step explanation:
If a line passes through a points with slope m, then the point slope form of the line is
It is given that the slope of the line is 1.9 and it passes through the point (4.5, -1.4). So, the equation of line in point-slope form is
It is given that the slope of the line is 2 and it passes through the point (-8,1). So, the equation of line in point-slope form is
Answer:
0.
Step-by-step explanation:
sin 12 = cos(90 - 12) = cos 78 so the answer is 0.
