lower than the national average. a survey covering 10 different suburbs in dallas
found the average price of gasoline to be $3.924 per gallon with a population standard
deviation of $0.053. what critical value should be used to test the claim using
a= 0.01?
a) -2.33
b) 1.26
c) 2.33
d) -1.26

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
