Answer:
1428
Step-by-step explanation:
We first find the surface area of the triangle=base times height/2
height=8
We add 15+6=21, 21 times 8=168/2=84
We have 84 for this triangle, so the other triangle's area would also be 84
Now we find the area of the rectangle on the bottom-30 times 15=450
We then find the area of the other rectangle on the right side of the prism=30 times 17=510
Finally the area of the left-side of the prism=30 times 10=300
For the surface area, we add these all up=84+84+450+510+300=1428
Answer and explanation:
Given : A driving exam consists of 29 multiple-choice questions. Each of the 29 answers is either right or wrong. Suppose the probability that a student makes fewer than 6 mistakes on the exam is 0.26 and that the probability that a student makes from 6 to 20 (inclusive) mistakes is 0.53.
Let X be the number of mistake


To find : The probability of each of the following outcomes.
a) A student makes more than 20 mistakes
i.e. 





b. A student makes 6 or more mistakes
i.e. 


c. A student makes at most 20 mistakes
i.e. 
Using 'a' part 


d. Which two of these three events are complementary?
The complement of an event happening is the exact opposite: the probability of it not happening.
According to definition,
Option a and c are complementary events.
