Ou are a mechanic who is measuring the valve clearance on a motorcycle engine. the current clearance for one of the valves is 0.30 millimeter (mm). the clearance should be at least 0.18 mm and no more than 0.22 mm. the valve clearance is set by using a spacer that reduces the distance between the cam and the valve by the size of the spacer. spacers are available in 0.04 mm increments, and the spacer currently in the motorcycle engine is 2.84 mm. which of the following size spacers, in millimeters, should you use to achieve a correct valve clearance?

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

27 +27 or 27times 2=54

the diffrence is 0

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
