If you wanted to find the approximate average age of all students taking online coursework this summer (there are almost 2000), which would be the most practical
and efficient way to collect the data?
A) Perform an experiment
B) Use sampling
C) Take a census
D) Use a simulation

y = i/2 xtnop + (3i/2 tnop+ 1)

step-by-step explanation:

the picture is the step by step explanation.

i agree because i see the other persons thinking is clear

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
