Aconsumer advocate wants to collect a sample of jelly jars and measure the actual weight of the product in the container. he needs to collect enough data to construct a confidence interval with a margin of error of no more than 3 grams with 95% confidence. the standard deviation of these jars is usually 3 grams. estimate the minimum sample size required.

Aprojectile is thrown upward so that its distance above the ground after t seconds is given by the function h(t) = -16t2 + 704t. after how many seconds does the projectile take to reach its maximum height?

Afield is shaped like the figure shown

The equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true? a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of 5/9 degree celsius. a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit. a temperature increase of 5/9 degree fahrenheit is equivalent to a temperature increase of 1 degree celsius. a) i only b) ii only c) iii only d) i and ii only
