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.
1st :The angle of depression 30° = the angle of elevation (from the truck to the height of the building.
2nd :
cos 30° = (adjacent side)/(hypotenuse)
cos 30° = x/100, but cos 30°= (√3)/2
(√3)/2 = x/100 and x = (100√3)/2
and x = (50.√3) = 86.60 m
Combining the like-terms, the result of the addition of polynomials f(x) and g(x) is given by:

<h3>How do we add polynomials?</h3>
We add polynomials combining the like-terms, that is, adding terms with the same exponent.
In this problem, the polynomials are:

Answer:
(x+13)2.3 if simplifying.
Step-by-step explanation:
sum means add. so x plus 13 times 2.3 or 2.3(x+13)
Answer:
Step-by-step explanation:
An equation is 5p + 2 = 18.5.
The 1950 population was approximately 3.3 million.
Step-by-step explanation:
If p million was the population in 1950 the equation is:
5p + 2 = 18.5
5p = 16.5
p = 16.5 / 5
p = 3.3 million.
