A survey was given to a random sample of 350 residents of a town to determine whether they support a new plan to raise taxes in order to increase education
spending. Of those surveyed, 20% of the people said they were in favor of the plan. At
the 95% confidence level, what is the margin of error for this survey expressed as a
percentage to the nearest tenth? (Do not write =).

In the following situation, determine whether you are asked to determine the number of permutations or combinations. then do the calculation how many ways are there to pick a starting five from a basketball team of twelve members? a. permutation; ps - 2520 b. combination; 1c, - 792 c. combination: 2cs - 2520 d. permutation; ps - 95040

Write the sine and cosine values of a, b, respectively, in the figure for (1) and (2) + explanation.

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
