Based on the information given, the value of the area of the irregular figure will be 13.7 ft².
<h3>How to calculate the area.</h3>
From the complete question, the area of a triangle will be:
= 0.5 x base x height
= 0.5 x 3.6 x 4.8
= 8.64 ft²
Area of the semicircle = 0.5πr²
Area of the semicircle = 0.5 x 3.14 x 1.8²
Area of the semicircle = 5.09 ft²
Area of the irregular figure = Area of the semicircle + Area of the triangle
= 5.09 ft² + 8.64 ft²
= 13.73ft² = 13.7 ft²

95.44% IQ scores are between 77 and 125
We're given,
Mean (a)=101
standard deviation (b)=12
To find : ![P[77 < x < 125]](https://tex.z-dn.net/?f=P%5B77%20%3C%20x%20%3C%20125%5D)
Using Empirical Rule:
∴ 
![P[\frac{77-101}{12} < \frac{x-a}{b} < \frac{125-101}{12}]\\](https://tex.z-dn.net/?f=P%5B%5Cfrac%7B77-101%7D%7B12%7D%20%3C%20%5Cfrac%7Bx-a%7D%7Bb%7D%20%3C%20%5Cfrac%7B125-101%7D%7B12%7D%5D%5C%5C)
![=P[-2 < z < 2]\\](https://tex.z-dn.net/?f=%3DP%5B-2%20%3C%20z%20%3C%202%5D%5C%5C)
![=P[Z < 2]-P[Z < -2]\\](https://tex.z-dn.net/?f=%3DP%5BZ%20%3C%202%5D-P%5BZ%20%3C%20-2%5D%5C%5C)

North/South America:
New World monkeys inhabit the New World, which includes North and South America.
Africa and Asia:
Prosimians, the earliest of the primates, inhabit regions of Africa and Asia.
Old World monkeys still live in Africa and Asia. Fossil species also lived in Europe.
Apes are Old World primates. They are found today in Africa and Asia.
<h3>What is the group of Primates?</h3>
The primates are;
- New World monkeys
- Prosimians
- Old World monkeys
- Apes
The groups are;
North/South America
Africa and Asia
New World monkeys inhabit the New World, which includes North and South America.
Prosimians, the earliest of the primates, inhabit regions of Africa and Asia. This also applies to Apes and Old monkeys.
Thus;

The true statement about the graph of f(x) is 
The graph of f(x) is a straight line that passes through the points (-5,0) and (0,3).
Start by calculating the slope (m)
So, we have:
Simplify
The equation of the line is then calculated as:
This gives
Open bracket
Express y as a function of x
Hence, the true statement about the graph of f(x) is
