Answer:
0.25
Step-by-step explanation:
72% of courses have final exams and 46% of courses require research papers which means probability of 0.72 for courses that have final exams and 0.46 for courses that require research papers.
31% of courses have a research paper and a final exam, which means probability of 0.31 for both courses with exams and research papers, using Venn diagram approach, find picture attached to the solution.
P(R or E) = P(R) + P(E) - P(R and E), which gives:
P(R or E) = 0.15 + 0.41 - 0.31
P(R or E) = 0.25.
Answer: 8.1%
Step-by-step explanation:
Given :
Let x be the random variable that represents the actual speeds of cars.
The speed limit on a road is 60 mph.
Using formula , , we have for x= 60+10=70
Using z-table for right-tailed test value, The probability of cars exceed the speed limit by more than 10 mph will be
Hence, the percentage of cars exceed the speed limit by more than 10 mph is 8.1%.
Explanation:
Quadrants 2 and 3 houses points that have negative x-values, while as Quadrants 1 and 4 houses points that have positive x-values.
If 'your sister' completes the text with negative y-value, the point would be in Q3.
If 'your sister' completes the text with positive y-value, the point would be in Q2.
