The stock of Company A lost $2.55 throughout the day and ended at a value of $57.45. By what percentage did the stock decline?

Determine the number of outcomes in the event. decide whether the event is a simple event or not. upper a computer is used to select randomly a number between 1 and 9 comma inclusive. event upper b is selecting a number greater than 4. event upper b has nothing outcome(s). is the event a simple event? (yes or no) because event upper b has (fewer than, exactly, more than) one outcome.

Write an algebraic expression to match each statement a. four less than 8 times a number b. twice the difference of a number and six c. nine from a number squared

Which shows the correct substitution of the values a, b and c from the equation 1=-2x+3x^2+1
