The number of wins for a high school football team is measured for the season. when the team plays at home, it is generally believed that they will win. comparing the location of the game and the number of wins, a correlation coefficient of −0.91 is calculated. what would this imply about the football team winning at home?
a. the scatter plot would closely resemble a straight line with a negative slope. the data has a strong negative correlation, and a causal relationship exists between the team playing at home and winning.
b. the scatter plot would closely resemble a straight line with a negative slope. the data has a strong, negative correlation, but causation cannot be determined.
c. the scatter plot would not represented by a line of best fit with a negative slope. there is a weak correlation between the football team playing at home and winning.
d. there is no causation and almost no correlation between the football team playing at home and winning.

Isuck at math ; ^; m a student solved this problem and said the answer is 3 feet. chase had a roll of ribbon that contained 7 7/8 feet of ribbon. he cut off one piece that was 3 5/8 feet long and another piece that was 1 1/4 feet from the roll. how much ribbon was left on the roll? is the student's answer reasonable? yes, the answer is reasonable. no, the answer is not reasonable. it should be about 2 feet. no, the answer is not reasonable. it should be about 13 feet. no, the answer is not reasonable. it should be about 4 feet.

If m∠abc = 70°, what is m∠abd? justify your reasoning. using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°. using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°. using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality. using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
