MATH MODERN MIDTERM- EXAM What do you call the single value that attempts to describe a set of data by identifying the central position within that set of data? ANSWER: Measure Of Central Tendency What do you call the method developed to help solve large, real-world linear programming problems? ANSWER : Simplex Method Successful problems solvers uses a variety of techniques when they attempt to solve a problem. The following techniques are most useful ANSWER: Devise a Plan Ayaka scored the following on his mathematics tests: 60 ,75 ,80 ,75 ,70 ,90 , 91 , 84 ,61 ,75. What is the standard deviation of her test scores? Round off your answer to the nearest hundredths. ANSWER: 10.10 It refers to a collection of numbers or values that relate to a particular subject. ANSWER: Data set Sunshine holds two part-time jobs, Job 1 and Job 2. She never wants to work 56 hours a week. If Sunshine makes $99.13 an hour at Job 1, and $56.37 an hour at Job 2, how many hours should she work per week at each job to maximize her income? Conditions: No zero constraints/ She should at least work 21 hours in Job 1 and 16 hours in Job 2  

Answer format: Job1=36.21/Job2=22.21 Answer must be rounded off to two decimal places

ANSWER: Job1=40/Job2=16 It refers to the middle number if n is odd for a ranked order list of numbers. ANSWER: Median What do you call the measure of the strength of a linear association between two variables and is denoted by r? ANSWER: Pearson product-moment correlation coefficient

What kind of correlation shows no linear dependence or no relation between the two variables? ANSWER; No Correlation In a linear programming problem, it is the maximal value for profit. ANSWER: Corner Point Principle The mean for data set: 10,12,15,16 ,8, 7 is ANSWER: 11.33 It is a policy that gives you the optimal number of each product to produce. ANSWER: Optimal Production Policy Identify which of the statements shown below is NOT an Essential of Linear Programming Models. ANSWER: Complexity It refers to the number that occurs most frequently in a list of numbers. ANSWER: Mode Suppose that a marketing firm conducts a survey of 1,000 households, determine the average number of TVs each household owns. ANSWER: 3 Find the quartiles (Q1, Q2, Q3) of the data set shown below: D ={98, 88, 78, 99, 84, 80, 62, 44, 49, 70, 33, 35} ANSWER: Q1=46.5/Q2=74/Q3=86 In an exam, students in a class scored as follows: S= [45, 67, 95, 89, 88, 40, 90, 88, 56, 78, 88, 76]

ANSWER: 88 What do you call the technique used to model the dependency of one dependent variable upon one independent variable? ANSWER: Simple Linear Regression Ayaka is 12 years older than Joshua. Five years ago, the sum of their ages was 28. How old are they now? ANSWER: Ayaka=25/Joshua=13

Find the Simple Linear Regression Formula of the data set shown below: Where the monthly e-commerce sales is Y and online advertising costs X. Note: Round off your answers to two decimal places. No spaces in between characters. Example format for the Final answer: y=36.11x+23.22 ANSWER: y=171.47x+125.83 The sum of a two-digit number's digits is 11. When the digits are swapped, the resulting number is 45 less than the original. Find the original number. ANSWER: 83 Who established and developed Linear Programming? ANSWER: Leonid Kantorovich Find the Pearson product-moment correlation coefficient of the data set shown below: Where the car price is Y and car age is the X. Note: Round off your answers to four decimal places. No spaces in between characters. Example format for the Final answer: r=0.12 ANSWER: r=-0.9550 Once a plan has been devised it must be carried out. ANSWER: Carry out of the plan Find the variance of [6 ,7 ,10 ,11 ,12 ,13 ,16 ,18 ,25]. ANSWER: 30.77

To be able to solve a problem, understanding what the problem asks for is very important. ANSWER: Understand the problem What do you call the type of correlation when the value of one variable increases with respect to another? ANSWER: Positive Correlation How many of your batchmates have you surpassed if your graduation rank in high school is 56th percentile out of 2136 students? ANSWER: 1196 Find the median from a set of numbers divisible by 5 from 1 to 50 ANSWER: 27.5

It is the region which consists of all possible solution choices for a particular problem

ANSWER: Feasible Region...
