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.
No
X would have to equal 6 or greater as if x was 5
5+3 is the same as 8
Exact form 27/4
decimal form 6.75
mixed number form 6(3/4)
Y= 1/10x + 2/10 is what you are left with once the equation is simplified
Answer: The jet will fly 4400miles in 8 hours.
Step-by-step explanation:
Let the missing value be represented by x
2 hours = 1100 miles
8 hours = x
We cross multiply:
2x = 1100 x 8
2x = 8800
Divide both sides by 2 to get the value of x
x = 8800/2
x = 4400
Therefore, the jet will fly 4400miles in 8 hours.
