Sunshine stereo cassette decks have a deck life that is normally distributed with a mean of 2.3 years and a standard deviation of 0.4 years. . For how many years should the cassette deck be insured to be 95% confident that it will last beyond the insurance date. _years. Round to 1
decimal place.

Rest of the question on the image.

Find the value of 1715⋅211.though these numbers aren't quite as nice as the ones from the example or the previous part, the procedure is the same, so this is really no more difficult. give the numerator followed by the denominator, separated by a comma.

Find the pattern and use it to list the nth term in the sequence. 6, 12, 20, 30, 42, 56, the nth term of the sequence is

The box plots show the distributions of the numbers of words per line in an essay printed in two different fonts.which measure of center would be best to compare the data sets? the median is the best measure because both distributions are left-skewed.the mean is the best measure because both distributions are left-skewed.the median is the best measure because both distributions are symmetric.the mean is the best measure because both distributions are symmetric
