Test 4 Results If you got less than 70 on Test 4 make sure to go over your test with me or a TA sometime this week This material will also be covered again on the final exam Average class score after partial credit Commonly missed questions Now please CLOSE YOUR LAPTOPS and turn off and put away your cell phones Make sure you know the day and time of the final exam for this section of Math 110 Day Date Time to All Math 110 finals will be given in your regular classroom Final exam schedules for all sections are posted on the bulletin board and in your course syllabus Math 110 Final Exam Comprehensive covers the whole semester Worth 200 points 20 of course grade 47 questions Test period is one hour and 50 minutes Practice Final is worth 10 points and also has 47 questions and unlimited tries Your best score on the practice final will also earn up to 20 extra credit points on the final The practice final is due at the scheduled start time of this section s final exam IMPORTANT NOTE To get access to the practice final you must have submitted all four final exam review homework assignments and have scored at least 80 on each one Final Exam Review Materials 1 Four review homework assignments These are each worth 15 points vs the usual homework assignment of 4 points Unit 1 review homework Chapters 1 2 3 Due at the start of the next class session Unit 2 review homework Chapters 4 5 8 NOTE You must get at least 80 on the Unit 1 Review before you can start the Unit 2 review Due at the start of the second to last class session Unit 3 review homework Chapter 6 NOTE You must get at least 80 on the Unit 2 Review before you can start the Unit 3 review Due at the start of the last class session Unit 4 review homework Chapter 7 NOTE You must get at least 80 on the Unit 3 Review before you can start the Unit 4 review Check with your teacher for due date and time Final Exam Review Materials 2 Comprehensive Practice Final NOTE You must get at least 80 on the Unit 4 Review Homework before you can start the comprehensive practice final The practice final has 47 questions as does the regular final exam The questions will NOT be exactly the same as those on the regular final but they will be similar in content and are distributed across sections the same way as on the regular final Each time you take the practice final you will get a different set of questions AND your highest score will earn you that percentage of 20 extra credit points on the final so it will pay off if you can find the time to take it more than once Comprehensive Practice Final Once you finish the Unit 4 Final Review homework with at least an 80 score you will have access to the practice final with as many attempts as you want The practice final is worth 10 points plus a possible bonus of up to 20 extra credit points on the final exam Your best percentage score on the practice final will earn that percent of 10 points toward your course grade plus that best score percent times 20 extra credit points will be added on to your final exam point score before partial credit points are added This makes it extremely important for you to make sure you work to get at least 80 on each of the four final exam review homework assignments so that you can get access to the practice final Math TLC Open Lab Hours Room 203 Jarvis Hall Science Wing Regular hours through

Q of all numbers that can be expressed as a quotient of integers with denominator 0 Irrational numbers the set I of all numbers that can NOT be expressed as a quotient of integers Real numbers the set R of all rational and irrational numbers combined NOTE Q is a subset of R I is a subset of R but Q and I have NO members in common Commutative property of addition a b b a of multiplication a b b a Associative property of addition a b c a b c of multiplication a b c a b c Distributive property of multiplication over addition a b c ab ac Applications of Linear Equations Sections 2 2 and 2 3 contained many types of word problems You should review these two homework assignments using the online Gradebook sometime before your final in addition to the review homework problems for this unit Don t forget that if both sides of an inequality are multiplied or divided by a negative number the direction of the inequality sign MUST BE REVERSED Example 7 x 2 x 4 5 x 12 7x 14 x 20 4x 12 use distributive property 8x 14 4x 32 simplify both sides 8x 4x 14 4x 4x 32 add 4x to both sides 4x 14 32 simplify both sides 4x 14 14 32 14 subtract 14 from both sides 4x 18 simplify both sides 9 x 2 Graph of solution 9 2 divide both sides by 4 and simplify 9 2 Highlights from Chapter 3 Slope of a line Informally slope is the tilt of a line It is the ratio of vertical change to horizontal change or rise y change y2 y1 m run x change x2 x1 x2 x1 Slope intercept form of a line y mx b has a slope of m and has a y intercept of 0 b This form is useful for graphing since you have a point and the slope readily visible Example Find the slope and y intercept of the line 2x 6y 12 First we need to solve the linear equation for y 6y 2x 12 subtract 2x from both sides 1 3 y x 2 divide both sides by 6 Since the equation is now in the form of y mx b slope is 1 3 y intercept is 0 2 The slope intercept form uses specifically the y intercept in the equation The point slope form allows you to use ANY …
