Aschool is planning a field trip for 142 people. the trip will use 6 drivers and 2 types of vehicles: buses and vans. a bus can seat 51 people. a van can seat 10 people. write and solve a system of equations to find out how many buses and how many vans will be needed.

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)

Find the number of real number solutions for the equation. x2 + 5x + 7 = 0 0 cannot be determined 1 2
