Mr. Lutor wants to explain how to use a shortcut method (that is, without using a calculator). To calculate how much money he must pay it is proposed: I. Convert the mixed number into an improper fraction

II. Multiply the improper fraction by 100%

III. Multiply the improper fraction by 1/100 and 76

IV. Simplify the fractions

V. Add the found value with 76

The proposal that DOESN´T allow calculating the total of money he must pay is:

NUMBER: 17 1/2

What is the probability of drawing three queens from a standard deck of cards, given that the first card drawn was a queen? assume that the cards are not replaced.

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)

Now max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
