Given expressions:
Area of a rectangle = L W
Area of a triangle =
Problem;
Create problems using the formula;
Solution:
Problem 1; Find the area of a rectangle whose length is 10cm and the width is half the size of the length?
Given parameters:
Length of rectangle = 10cm
Width of rectangle = x length =
x 10 = 5cm
So, the area of the rectangle = 10cm x 5cm = 50cm²
2. A triangle with a base length of 30cm and a height of 2cm will have an area of what?
Given parameters:
base length = 30cm
height = 2cm
Solution:
Area of a triangle = x b x h
Area of a triangle = x 30 x 2 = 30cm²
The area of the triangle will be 30cm²
Answer: Mean of the sample proportion = 74.4
Standard deviation of the samnple proportion is 5.32.
Step-by-step explanation:
Given : A random sample of 120 is taken from a population of 10000.
Let n = 120
Also, from previous survey, it is believed that 62% of the population has an Instagram account.
i.e, population proportion : p = 0.62
Now , the mean of the sample proportin would be :
i.e. Mean of the sample proportion = 74.4
The standard deviation of the samnple proportion would be :
Thus , the standard deviation of the samnple proportion is 5.32.
