Astudy was conducted to determine the effectiveness of varying amounts of vitamin c in reducing the number of common colds. a survey of 450 people provided the following information:

daily amount of vitamin c taken
none 500 mg 1000 mg
no colds 57 26 17
at least one cold 223 84 43

what conclusion can be made?

a.) approximately 64% of the people that had at least one cold did not take vitamin c.
b.) the data proves that vitamin c has no effect on the number of common colds.
c.) the data proves that vitamin c reduces the number of common colds.
d.) approximately 50% of the people that had at least one cold did not take vitamin c.
e.) since common colds are caused by viruses, there is no reason to conclude that vitamin c could have any effect.

(i really need ) read the story problem, and then answer the questions that follow. gordon works for a graphic design firm and is creating a label for a food truck vendor. the vendor specializes in finger food and wants to sell food in right conical containers so that they are easy for people to hold. to complete his label, gordon needs to collect several different measurements to ensure that the label he designs will fit the surface of the container. gordon has been told that the containers have a diameter of 4 inches and a height of 6 inches. part a: find the slant height of the cone. the slant height is the distance from the apex, or tip, to the base along the cone’s lateral surface. show your work. part b: find the measure of the angle formed between the base of the cone and a line segment that represents the slant height. part c: imagine two line segments where each represents a slant height of the cone. the segments are on opposite sides of the cone and meet at the apex. find the measurement of the angle formed between the line segments.
