A cactus casts a Shadow that is 15 ft long . A gate nearby casts a shadow that is 5 ft long at the same Moment . If the height of a gate is 3 ft long, what is the height of the cactus??

Given this information, which expression must represent the value of b?

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.)

Which expression is not a polynomial?
