She has one more gift to buy and wants her mean cost to be $24. What should she spend for the last gift? 3 Methods : Method 1: Guess & heck Try $30 pplication Problems - Method = Try a greater price, such as $ = 24 5 The answer is $32. Slide 41 / 141 pplication Problems - Method 3 pplication Problems - Method 2 Jae bought gifts that cost $24, $26, $20 and $1. She has one more gift to buy and wants her mean cost to be $24. What should she spend for the last gift? Method 2: Work ackward In order to have a mean of $24 on 5 gifts, the sum of all 5 gifts must be $24 5 = $120. The sum of the first four gifts is $. So the last gift should cost $120 $ = $ = = 32 Slide 42 / 141 pplication Problems - Method 3 Method 3: Write an quation Let x = Jae's cost for the last gift x = x = x = 120 (multiplied both sides by 5) x = 32 (subtracted from both sides) our test scores are 7, 6, 9, and. ou have one more test in the marking period. ou want your average to be a 90.

To create a frequency table, choose a scale that includes all of the numbers in the data set. Next, determine an interval to separate the scale into equal parts. The table should have the intervals in the first column, tally in the second and frequency in the third.

Time spent studying Slide 113 / 141 raw a Line Notice that the points form a linear like pattern. To draw a line of best fit, use two points so that the line is as close as possible to the data points. Slide 114 / onsider the scatter graph to answer the following: Which 2 points would give the best line of fit? and and and there is no pattern X Our line is drawn so that it fits as close as possible to the data points.

21 Slide 117 / 141 raw a Line The points form a linear like pattern, so use two of the points to draw a line of best fit. Slide 11 / 141 Prediction quation Use the two points that formed the line to write an equation for the line. Find m Find b = 50 + b m = = + b m = = b S = 15 t Our line is drawn so that it fits as close as possible to the data points. This line was drawn through (35,2) and (50,90). Slide 119 / 141 xtrapolation Prediction quations can be used to predict other related values. Where S is the score for t minutes of studying. This equation is called the Prediction quation. Slide 120 / 141 Interpolation If a person studies 42 minutes, what would be the predicted score? S = 15 t If a person studies 15 minutes, what would be the predicted score? S = 190 (15) S = (42) This is an interpolation, because the time was inside the range of the original times. This is an extrapolation, because the time was outside the range of the original times. Slide 121 / 141 What is Wrong? Interpolations are more accurate because they are within the set. The farther points are away from the data set the less reliable the prediction. Using the same prediction equation, consider: If a person studies 120 minutes, what will be there score? S = (120) What is wrong with this prediction? Slide 122 / 141 What is the Prediction? If a student got an 0 on the test, What would be the predicted length of their study time? 0 = 190 t = 15 t = t The student studied about 31 minutes.

Which of the predicted values (7,5) or (14, 2) will be more accurate and why? (7,5); it is an interpolation (7,5); there already is a 5 and a 7 in the table (14, -2) it is an extrapolation (14, -2); the line is going down and will become negative X
