1. A butterfly is clinging to the tip of one blade of a windmill. The center of the windmill is 30 feet above ground and has a radius of 8 feet. It takes the windmill 20 seconds to complete one revolution. The butterfly's path
begins in the 9 o'clock position and the blade rotates clockwise. Write an equation that can be used to calculate
the butterfly's height off of the ground at any time during the 'ride. Then use the equation to calculate its
height after riding for 17 seconds.

Aclass consists of 55% boys and 45% girls. it is observed that 25% of the class are boys and scored an a on the test, and 35% of the class are girls and scored an a on the test. if a student is chosen at random and is found to be a girl, the probability that the student scored an ais

25 ! the line of best fit is h = 5a + 86. predict the height at age 16.

Martha has a deck of cards. she has lost some of the cards, and now the deck only contains nine spades, eleven diamonds, eight clubs, and twelve hearts. martha predicts that whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time. which activity would best allow martha to test her prediction? a. randomly draw a card from the box and see if it is a club. b. randomly draw a card. then, continue to draw another card until all eight clubs are drawn. c. randomly draw and replace a card 120 times. then, observe how close to 30 times a club is drawn. d. randomly draw and replace a card 100 times. then, observe how close to 20 times a club is drawn.
