Asurvey of 1,000 men and women asked, "do you earn over $50,000 per year? " the table below shows the responses for males and females: male female total income over $50,000 475 375 850 income below $50,000 75 75 150 total 550 450 1,000 based on these data, are "being female" and "earning over $50,000" independent events?

You are given the table

The events A and B are independent when

1. The probability "being female" is

2. The probability "earning over $50,000" is

3. The probability of "being female and earning over $50,000" is

Since these events are dependent.

x = 23.78

step-by-step explanation:

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
