1st question answer is owning a dog or owning a cat

the second question answer is 7

Step-by-step explanation:

1)mutually exclusive means 2 things that cannot happen at the same times. so its asking which is NOT an example so u can own a dog and a cat at the same time

2)the answer is 7 because 11 ppl buy contact lenses and 4 people buy glasses. 11-4=7

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
