<h3>What is percentage decrease?</h3>Percentage decrease is the amount deducted or reduced from the initial value in the percentage part.
In the year 2017, an estimated 4,347,000 people in this country are illiterate. With new incentives and funding, The country is hoping to cut that number by 14% every year.
Total year from 2017 to 2025 are 8 years. Thus, use the following formula of compound interest to find percentage decrease:
Here, A is the final population, The initial population is P, the rate is r and the time period is t. Put the values,
Thus, the number of people of the country which is predicted will be illiterate in the year 2025 are 1,300,700.

Answer:
a) The value of A = 2
b) The value of
Step-by-step explanation:
a)
Given that:
X should be the random variable that assumes only positive integer values.
The probability function; for some constant A and n ≥ 1.
Then, let
This implies that:
A = 2
Thus, the value of A = 2
b)
Suppose X represents a e constant A (n> 1). Find A.
b) Let X be a continuous random variable that can assume values between 0 and 3
Then, the density function of x is:
where; B is constant.
Then, using the property of the probability density function:
Taking the integral, we have:
B [ 9 +3 ] = 1
B [ 12 ] = 1
Divide both sides by 12
