W The number of days, d, to build a house is given by
780
d =
where w is the number of workers used each day on site.
Bob's company will take 60 days to build the house.
Pat's company will take 39 days to build the house.
Pat's company will have to use more workers each day than Bob's company.
How many more?
Note: Make your final answer clear by writing "... more".

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

answer: .64

step-by-step explanation

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

in 2010, the population of the state of california is 37.29 × 10⁶

step-by-step explanation:

population of los angeles = 3.79 × 10⁶

population of california = 9.84 × population of los angeles

                                        = 9.84 × 3.79 × 10⁶

                                        = 37.2936 × 10⁶

                                        = 37.29 × 10⁶

∴ in 2010, the population of the state of california is 37.29 × 10⁶

so mark-up is 0.4 multiplied by 180 = 72
