Laila is visiting the grounds of an ancient burial site in the shape of a pyramid and is hoping to find old buried artifacts and sell them to a museum. Historians have told her that there is only 1 undiscovered artifact per side of the pyramid. She plans to look on all 4 sides of the pyramid and assumes that on each side there is a 50, percent chance of her finding that side’s artifact independent of the other sides. The table below shows the resale value depending on how many artifacts she finds. What is the expected value of the resale value of the artifacts Laila finds?

Artifacts found 0 1 2 3 4

Resale value $0 $100 $250 $500 $1000

$306.25 (Khan)

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257
