3. Mr. Yardi will buy pens for all 19 employees at his store. He wants to give
each employee 3 pens. If he buys pens
in packages of 12, what is the minimum
number of packages of pens Mr. Yardi
needs to buy to have enough pens?

(a) compute the maclaurin polynomial m2(x) for f(x) = cos x. (b) use the polynomial of part (a) to estimate cos π 12. (c) use a calculator to compute the error made using the estimate from part (b) for the value of cos π 12. remember that the error is defined to be the absolute value of the difference between the true value and the estimate.

Is the figure congruent? yes or no?

Scores on the cognitive scale of the bayley-scales of infant and toddler development range from 1 to 19, with a standard deviation of 3. calculate the margin of error in estimating the true mean cognitive scale score, with 99% confidence, if there are 12 infants and toddlers in a sample.
