7) A student group postulates that the stride length, L, of a marathon runner is proportional to a runner’s inseam, H, and inversely proportional to the square of a runner’s weight, W. The inseam length is to be measured using a tape measure and the weight using a scale. The estimated uncertainties for H and W are 6% and 5% respectively, based upon a typical inseam of 70 cm and a weight of 600N. Determine the fractional uncertainty in L

the answer will be the last one

factor trees are nice.

probably the last option

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
