At a high school movie night, the refreshments stand sells popcorn and soft drinks. Of the 100 students who came to the movie, 62 bought popcorn and 47 bought a drink. 38 students bought both popcorn and a drink.

Are buying a drink and buying popcorn independent or dependent events? Justify your answer.

Buying a drink and buying popcorn are independent events.

Step-by-step explanation:

Independent events are referred to as events whose occurrence does not affect the occurrence of another event.

In the case of this question, 62 bought popcorn while 47 bought a drink.

This means that the buying of popcorn by a student does not mean buying of a drink. It does not affect each other.

I hope this helps.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
