Abusiness owner pays $1200 a month and a total of $120 per hour in employee salary for each our list doors open on our roots the store brings in $200 in net sales per hour which equation can be solved it to turman the break even point if c(x) represents the cost function r(x) represents the revenue function and eggs the number of hours per month the store is open
a) c(x)=1,200+120xr(x)=200x
b) c(x)=1,200+120r(x)=200x
c) c(x)=200xr(x)=1,200+120x
d) c(x)=200xr(x)=1,200+120

The points (1, 7) and (0, 2) fall on a particular line. what is its equation in slope-intercept form?

Farmers know that driving heavy equipment on wet soil compresses the soil and injures future crops. here are data on the "penetrability" of the same type of soil at two levels of compression. penetrability is a measure of how much resistance plant roots will meet when they try to grow through the soil. compressed soil 2.85 2.66 3 2.82 2.76 2.81 2.78 3.08 2.94 2.86 3.08 2.82 2.78 2.98 3.00 2.78 2.96 2.90 3.18 3.16 intermediate soil 3.17 3.37 3.1 3.40 3.38 3.14 3.18 3.26 2.96 3.02 3.54 3.36 3.18 3.12 3.86 2.92 3.46 3.44 3.62 4.26 use the data, omitting the high outlier, to give a 95% confidence interval for the decrease in penetrability of compressed soil relative to intermediate soil. compute degrees of freedom using the conservative method. interval: to
