The number of newly reported crime cases in a county in New York State is shown in the accompanying table, where x represents the number of years since 2006, and y
represents number of new cases. Write the linear regression equation that represents
this set of data, rounding all coefficients to the nearest tenth. Using this equation,
estimate the calendar year in which the number of new cases would reach 767.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
