There are 16 females and 20 males in a class. Part A. What is the theoretical probability that a randomly chosen student is female? Explain your reasoning. One week later, there are 45 students in the class. The theoretical probability that a randomly chosen female is the same as last week. How many males joined the class? Justify your answer.

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get

the answer would be a 24
