Awell-designed and safe workplace can contribute greatly to increased productivity. it is especially important that workers not be asked to perform tasks, such as lifting, that exceed their capabilities. the accompanying data on maximum weight of lift (mawl, in kg) for a frequency of four lifts/min was reported in the article the effects of speed, frequency, and load on measured hand forces for a floor-to-knuckle lifting task (ergonomics, 1992: 833843); subjects were randomly selected from the population of healthy males ages 1830. assuming that mawl is normally distributed, does the data suggest that the population mean mawl exceeds 25?

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

alright well the answers to your question is

2xy/9 hope this have a nice day : )

step-by-step explanation:

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
