Question 1
Drag the orange points on the cylinder and the cone to change their radii and heights. (Make sure the Freeze height checkboxes are not checked.)
Set equal radii and heights for the cylinder and the cone, and note their respective volumes. Record the volumes for a few sets of heights and
radil, and calculate the ratio of the volumes in each case. Remember, make sure the height and radius of the cone and the cylinder are the same
in each pair. (You might see some discrepancies in the tool due to rounding of decimals.) Round your calculations for ratio to the hundredths
place. The first one has been done for you.

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.

Scores on a university exam are normally distributed with a mean of 78 and a standard deviation of 8. the professor teaching the class declares that a score of 70 or higher is required for a grade of at least “c.” using the 68-95-99.7 rule, what percentage of students failed to earn a grade of at least “c”?
