The correlation coefficient for blood pressure and amount of vegetables eaten in a group of people is −0.7. analyze the following statement:

is this a reasonable conclusion?

no; blood pressure and eating vegetables are completely unrelated
no; even though there is a strong negative correlation, not eating vegetables doesn't necessarily cause high blood pressure
yes; eating vegetables reduces blood pressure, so the opposite is also true
yes; the correlation coefficient is below −0.5, so that implies causation

Fran would like to estimate the mean amount of time it takes people in her town to travel to work. the town's population is 150,000 and about 90,000 of those are working adults. which statements are true? select each correct answer. there is no way to infer the value of the mean. she must collect data for all 90,000 working adults and calculate the mean. a larger sample of working adults will provide a better estimate of the true mean than a smaller sample. the population of working adults is too large for using a sample to estimate the mean of the entire group. if she takes a random sample of the population of working adults in her town, the mean for that group is likely close to the mean for the entire group.

Lines b and c are parallel. what is the measure of 2? m2 = 31° m2 = 50° m2 = 120° m2 = 130°

Shane and abha earned a team badge that required their team to collect no less than 2000 cans for recycling. abha collected 178 more cans than shane did. write an inequality to determine the number of cans, s, that shane could have collected.
