As part of a class project, a college student wanted to estimate the proportion of students at his college that owned a red car. to estimate this proportion he went to a large student parking lot during the middle of a class day. he found that 325 out of 1037 cars (31%) were red. this sample is best described as
a. a volunteer response sampleb. a convenience samplec. a stratified random sample with color of car as the stratad. a simple random sample

b. convenience sample

Step-by-step explanation:

Here , the student went to a large student parking lot during the middle of a class day.

Since in the middle of class it is convenient to collect sample of cars from parking lot .

Therefore , the sample is best described a "convenience sample".

Hence, the correct answer is b . convenience sample .

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
