Answer:
Given p = 0.07 as the probability that someone is a universal donor
In case of Geometric Distribution, Probability of getting the first success on nth trial is given by

where p is the probability of success on any one trial and (1-p) shows the probability of failure.
So the probability of the first subject to be a universal blood donor will be the seventh person is

So the final probability is 0.0453
Answer:
34. A negative number multiplied by a positive number will always have a negative product. The right answer should be -8.14.
35. When dividing fractions, you have to use the same-change-flip rule. The work should be like this: -1/4 x 2/3 = -2/12 = -1/6. The correct answer is -1/6.
36. In this problem, you need to convert 2 1/5 into a decimal, then multiply by -30. (2.2 x -30) The answer is -66 degrees.
Answer:
We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect
11 because if you count the spaces between the two places, the answer would be 11.
