State dmv records indicate that of all vehicles undergoing emissions testing during the previous year, 70% passed on the first try. a random sample of 200 cars tested in a particular county during the current year yields 124 that passed on the initial test. does this suggest that the true proportion for this county during the current year differs from the previous statewide proportion? test the relevant hypotheses using a 1⁄4 .05.

step-by-step explanation:

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
