Answer:
D
Step-by-step explanation:
Plug (5, 7) & (8, 13) into each equations and see which one of them makes mathematical sense. You'll find out that y=2x-3 is the right answer.
Using the binomial probability relation ; the probability that an head is obtained at least 50 times is 0.0271
<u>Using the binomial probability relation</u> :
- P(x = x) = nCx * p^x * q^(n-x)
- p = probability of success = 0.4
- q = 1 - p = 0.6
- n = number of trials = 100
P(x ≥ 50) = p(x = 50) + p(x = 51) + ...+ p(x = 100)
<u>Using a binomial probability calculator</u> :
P(x ≥ 100) = 0.0271
Therefore, the probability that atleast 50 heads are obtained in the trial is 0.0271

Answer:
6/5
Step-by-step explanation:
We can find the slope given two points by
m = (y2-y1)/(x2-x1)
= (1 - -5)/(7-2)
= (1+5)/(7-2)
=6/5
