Contrast the shapes of the data sets displayed in the box-and-whisker plots in Question 1. Explain what the difference in the shapes means in context of the situation. (b) Compare the spread of the data sets. Discuss both the overall spread and the spread within the boxes. (c) Use an appropriate measure of central tendency to compare the center of the data sets. Explain what the difference in those measures means in context of the situation. Answer

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

so, converting firstly the mixed fractions to improper fractions and then "adding".

the one below it is a function

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
