B: The least common multiple LCM of two integers is the smallest or least integer that is a multiple of both numbers. Because Utah is one of the first states to move to this research-based, effective method of instruction, textbook publishers were not motivated to prepare materials to support instruction.

C: According to the order of operations PEMDAS , evaluate any quantities or expressions in parentheses first. C: The appropriate unit of measure of a quantity corresponds to what you are counting when you measure it.

A monthly charge increases the amount of your debt. Which of the following could be your new balance? Calculate 24 x 6 - 2. Calculate the area of the right triangle below. The mean of a data set is 12, and its range is 8. Which of the following values could NOT be value in the set? The test scores in Mr. Smith's class are shown below. What unit of measure would be appropriate to use when investigating the attendance of nine different Broadway shows? D: A ratio is a relationship between two numbers of the same type. For instance, if the ratio of apples to oranges in a basket is 3:2, then the basket contains 3 apples for every 2 orange. In the given problem, we are looking for ratio between the populations of two cities. Since we are told that the population of New York is about twice that of Paris, there are about two New Yorkers for every Parisian. Therefore, the correct ratio is 2:1. C: A percent represents one part out of 100. B: The least common multiple LCM of two integers is the smallest or least integer that is a multiple of both numbers. One way to find the LCM of 8 and 12 is to list their multiples, and choose the smallest number that appears in both lists. Therefore, -60 could be your new balance. C: According to the order of operations PEMDAS , evaluate any quantities or expressions in parentheses first. A: A solution to an equation or inequality is a value of the variable s that makes the equation or inequality true. The only x to choose less than 3 is 2, so A is correct. A: The mean of a data set is its average. Therefore, unless all of the values in the set are 12 and you know they are not because the range is 8 , some of them must be less than 12 and some must be more than 12. The range of a data set is the difference between its largest and smallest values. Since the range of this set is 8, all values in the set have to be greater than 4. If one value was 4, there has to be a value greater than 12 to ensure the average stays 12, and the difference between that value and 4 would be more than 8. Since we know the range is 8, 4 could not be a value in the set. A: A histogram is a way of graphically representing the distribution of a data set. In a histogram, the data range is divided into intervals so that every value falls in one interval. For the given test scores, one natural way to set the intervals is 50 - 59, 60 - 69, 70 - 79, 80 - 89, and 90 - 100. Next calculate the number of values that fall within each interval, i. C: The appropriate unit of measure of a quantity corresponds to what you are counting when you measure it. To measure the attendance of the Broadway shows, you count the number of people who go to each show. Therefore, the unit of measure is people.

Part of the thinking is that if districts adopt, they may be more likely to also purchase professional development, which teachers alone cannot afford. D: A ratio is a relationship between two numbers of the same type. So far, she thinks the full curriculum is following suit. He says the team could always fundraise again. Part of the thinking is that if districts adopt, they may be more likely to also purchase professional development, which teachers alone cannot afford. Larry Singer A former Pearson executive, Singer has been taking notes in the last year not only from the educators using the resources, but also from what other publishers and companies in the OER space are doing. The range of a data set is the difference between its largest and smallest values.
