Distance between two villages = d
![(a) \: \frac{4}{5} \: of \: d = \frac{4}{5} d \\ \\ (b) \: \frac{3}{4} \: of \: d = \frac{3}{4} d \\ \\ (c) \: \frac{4}{5} d - \frac{3}{4} d = 1.5 \\ \\ \therefore \: \bigg(\frac{4}{5} - \frac{3}{4} \bigg) d = 1.5 \\ \\ \therefore \: \bigg(\frac{4 \times 4 - 3 \times 5}{5 \times 4} \bigg) d = 1.5 \\ \\ \therefore \: \bigg(\frac{16- 15}{20} \bigg) d = 1.5 \\ \\ \therefore \: \bigg(\frac{1}{20} \bigg) d = 1.5 \\ \\ \therefore \: d = 1.5 \times 20 \\ \\ \: \: \: \: \: \huge \orange{ \boxed{{ \therefore \: d = 30}}}](https://tex.z-dn.net/?f=%28a%29%20%5C%3A%20%20%5Cfrac%7B4%7D%7B5%7D%20%20%5C%3A%20of%20%5C%3A%20d%20%3D%20%20%5Cfrac%7B4%7D%7B5%7D%20d%20%5C%5C%20%20%5C%5C%20%28b%29%20%5C%3A%20%20%5Cfrac%7B3%7D%7B4%7D%20%20%5C%3A%20of%20%5C%3A%20d%20%3D%20%20%5Cfrac%7B3%7D%7B4%7D%20d%20%20%5C%5C%20%20%5C%5C%20%28c%29%20%5C%3A%20%5Cfrac%7B4%7D%7B5%7D%20d%20-%20%20%20%5Cfrac%7B3%7D%7B4%7D%20d%20%3D%201.5%20%5C%5C%20%20%5C%5C%20%20%5Ctherefore%20%5C%3A%20%20%20%5Cbigg%28%5Cfrac%7B4%7D%7B5%7D%20-%20%20%20%5Cfrac%7B3%7D%7B4%7D%20%5Cbigg%29%20d%20%3D%201.5%20%5C%5C%20%20%5C%5C%20%5Ctherefore%20%5C%3A%20%20%20%5Cbigg%28%5Cfrac%7B4%20%5Ctimes%204%20-%203%20%5Ctimes%205%7D%7B5%20%5Ctimes%204%7D%20%5Cbigg%29%20d%20%3D%201.5%20%5C%5C%20%20%5C%5C%20%5Ctherefore%20%5C%3A%20%20%20%5Cbigg%28%5Cfrac%7B16-%2015%7D%7B20%7D%20%5Cbigg%29%20d%20%3D%201.5%20%5C%5C%20%20%5C%5C%20%5Ctherefore%20%5C%3A%20%20%20%5Cbigg%28%5Cfrac%7B1%7D%7B20%7D%20%5Cbigg%29%20d%20%3D%201.5%20%5C%5C%20%20%5C%5C%20%5Ctherefore%20%5C%3A%20d%20%3D%201.5%20%5Ctimes%2020%20%5C%5C%20%20%5C%5C%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5Chuge%20%5Corange%7B%20%5Cboxed%7B%7B%20%5Ctherefore%20%5C%3A%20d%20%3D%2030%7D%7D%7D)
Kim's method of sampling the students in the given scenario is said to; It is not a random survey.
<h3>What is a random sample?</h3>
Random sampling is defined as a sampling technique whereby each sample has an equal probability of being chosen. This means that a sample chosen randomly is meant to be an unbiased representation of the total population.
In this question, we are told that Kim asked the first 50 kids to school in the morning about a question and used their responses to arrive at a conclusion.
Now, Kim's method is not random because it is biased as only those who came earliest were asked.

So all you have to do to solve these problems is substitute the y coordinate and the x coordinate into the equation.
So question 1 would be true because when you substitute the numbers in it equals the y value.
Question 2 is (4, -7)
Question 3 is False
Question 4 is true
Question 5 is true
See if you can do the rest!
Answer:
2754
Step-by-step explanation:
Given,
Length = 18 yards is equivalent to 54 feet
Width = 51 feet
So area of the field = Length * width
= 54 x 51
=2754 square feet
