Jake and 4 friends went to the movies. They each spent the same amount for their movie tickets and snacks. They spent a total of $57.50 for the tickets and snacks. Write a multiplication equation that can be used to find the total amount, t, that Jake and his 4 friends each spent.

|z| > (1/2) {-1/2, 1/2} {z|(-1/2) < z < (1/2)} {z|z < (-1/2) ∪ z > (1/2)}

Aprobability experiment is conducted in which the sample space of the experiment is s={7,8,9,10,11,12,13,14,15,16,17,18 }, event f={7,8,9,10,11,12}, and event g={11,12,13,14}. assume that each outcome is equally likely. list the outcomes in f or g. find p(f or g) by counting the number of outcomes in f or g. determine p(f or g) using the general addition rule.

The area of each triangle is 7 square units. the surface area of the triangular prism is
