which of the following could be used to calculate the total volume of grains that can be stored in the silo?

a) π(2ft)2(10ft) + one over threeπ(13ft − 10ft)2(2ft)
b) π(10ft)2(2ft) + one over threeπ(13ft − 10ft)2(2ft)
c) π(2ft)2(10ft) + one over threeπ(2ft)2(13ft − 10ft)
d) π(10ft)2(2ft) + one over threeπ(2ft)2(13ft − 10ft)

What signals you that factoring by grouping is the best method to use when factoring a problem?

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
