Answer:
<h3>If you had a line of x = 7, (or any time you have an equation where x equals a number) then you would have a vertical line. In every vertical line, the slope is undefined. In equations of lines that are in the format of y = mx + b, the slope is represented by the "m".</h3>
Answer:
0.9968
Step-by-step explanation:
Given that:
P of being correct = 0.5 (since there are only 2 options in each question with only one bring correct).
1 - p = 1 - 0.5 = 0.5
Number of questions, n = 12
Probability that atleast 2 questions are correct
P(x ≥ 2) = p(x = 2) + p(x = 3) +... + p(x = 12)
P(x =x) = nCx * p^x * (1 - p)^(n - x)
The sun of the individual probabilities gives us the answer or we could use the binomial probability calculator :
Hence,
P(x ≥ 2) = 0.9968
