Which is the best strategy to solve this problem?

mary-ann is making gift baskets for her friends. she has 32 candles and 64 lotion bottles. she splits the candles and lotion bottles equally among 8 baskets.

how many items were in each basket?

a.

draw a diagram.

draw 8 circles to represent baskets. think 32 ÷ 8 = 4, so draw 4 candles in each circle. think 64 ÷ 8 = 8, so draw 8 dots in each circle. count up the objects in a circle to find the number of items in each basket.

b.

guess and test.

guess that the number of items in each basket is 9. multiply 8 × 9. ask yourself if this is the same as the sum of 32 + 64? if not, revise your guess, and test your answer again.

c.

write a number sentence.

(32 + 64) × 8 =

The length of a rectangular piece of land is 92 yards more than three times its width. the perimeter is 760 yards. find its dimensions.

Select the two pairs of figures that are similar.

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
