We intend to estimate the average driving time of a group of commuters. from a previous study, we believe that the average time is 42 minutes with a standard deviation of 19 minutes. we want our 99% confidence interval to have a margin of error of no more than plus or minus 2 minutes. what is the smallest sample size

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.

happy to

pls mark as brainliest

r = 78539458390583095803458309458039485093485 or just 3

step-by-step explanation:

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
