An article reported the following data on oxygen consumption (mL/kg/min) for a sample of ten firefighters performing a fire-suppression simulation: 29.8 49.3 30.6 28.1 29.0 26.5 33.2 29.3 23.8 31.6

Compute the following. (Round your answers to four decimal places.)

a. The sample range 25,5 mL/kg/min
b. The sample variance s2 from the definition (i. e., by first computing deviations, then squaring them, etc.) mL2/kg2/min2
c. The sample standard deviation mL/kg/min
d. s2 using the shortcut method mL2/kg2/min2

the answer is a if my teacher taught me correct

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

2 1/2 feet
