To determine the distance that the mouse traveled each hour, Matt performed the calculations below. StartFraction 3 Over 24 EndFraction divided by 3 = StartFraction 3 Over (24 divided by 3) EndFraction = StartFraction 3 Over 8 EndFraction He concluded that the mouse traveled StartFraction 3 Over 8 EndFraction of a mile each hour. What is Matt’s error? Matt should have multiplied by 24, not divided. Matt should have multiplied by 3, not divided. Matt should have divided 3 by 3, not 24 by 3. Matt should have divided both 3 and 24 by 3. |

Three numbers have a mean of 17 a median of 20 a range of 27 Find the three numbers. |
|
Answer» ong>Answer: The mean, median and mode are types of average. The range gives a measure of the SPREAD of a set of data. This section revises how to calculate these measures for a simple set of data. It then goes on to look at how the measures can be calculated for a table of data. Calculating the Mean, Median, Mode and Range for simple data The table below shows how to calculate the mean, median, mode and range for two sets of data. Set A contains the numbers 2, 2, 3, 5, 5, 7, 8 and Set B contains the numbers 2, 3, 3, 4, 6, 7. Measure Set A 2, 2, 3, 5, 5, 7, 8 Set B 2, 3, 3, 4, 6, 7 The Mean To find the mean, you need to add up all the data, and then divide this total by the number of values in the data. Adding the numbers up gives: 2 + 2 + 3 + 5 + 5 + 7 + 8 = 32 There are 7 values, so you divide the total by 7: 32 ÷ 7 = 4.57... So the mean is 4.57 (2 d.p.) Adding the numbers up gives: 2 + 3 + 3 + 4 + 6 + 7 = 25 There are 6 values, so you divide the total by 6: 25 ÷ 6 = 4.166... So the mean is 4.17 (2 d.p.) The Median To find the median, you need to put the values in order, then find the middle value. If there are two values in the middle then you find the mean of these two values. The numbers in order: 2 , 2 , 3 , (5) , 5 , 7 , 8 The middle value is marked in brackets, and it is 5. So the median is 5 The numbers in order: 2 , 3 , (3 , 4) , 6 , 7 This time there are two values in the middle. They have been put in brackets. The median is found by calculating the mean of these two values: (3 + 4) ÷ 2 = 3.5 So the median is 3.5 The Mode The mode is the value which appears the most often in the data. It is possible to have more than one mode if there is more than one value which appears the most. The data values: 2 , 2 , 3 , 5 , 5 , 7 , 8 The values which appear most often are 2 and 5. They both appear more time than any of the other data values. So the modes are 2 and 5 The data values: 2 , 3 , 3 , 4 , 6 , 7 This time there is only one value which appears most often - the number 3. It appears more times than any of the other data values. So the mode is 3 The Range To find the range, you first need to find the lowest and highest values in the data. The range is found by subtracting the lowest value from the highest value. The data values: 2 , 2 , 3 , 5 , 5 , 7 , 8 The lowest value is 2 and the highest value is 8. Subtracting the lowest from the highest gives: 8 - 2 = 6 So the range is 6 The data values: 2 , 3 , 3 , 4 , 6 , 7 The lowest value is 2 and the highest value is 7. Subtracting the lowest from the highest gives: 7 - 2 = 5 So the range is 5 Practice QUESTION (for simple data) Work out the mean, median, mode and range for the simple data set below, then click on the button marked Click on this button below to see the correct answer to see whether you are correct. |

5 ,6, 14 ,41, 105, ? |
Answer» EN :- To FinD :-
SolutioN :-The first thing that comes in our mind is to subtract the consecutive terms and see if their difference follow certain pattern or not . So let's subtract the consecutive terms .
The difference of the consecutive terms we got is , 1 ,8 , 27 , 64 . If we notice then we can see that these are the cube of first 4 natural numbers that is 1 , 2 , 3 & 4 . We can write , 1 as 1³ , 8 as 2³ and so on . Hence the next number to be added is of cube of 5 that is 5³ = 125 . Therefore on adding 125 to 105 , we have 230. Hence the next term in this series is 230 . |

4. A manufacturer finds the opportunity to increase his business beyond his present or existing production capacity. In orderto decide whether to increase the production capacity, he would need a reliable information about increase in demand of theproduct, based on which only, he can commit his resources. He has two choices open to him, firstly, the expansion of theexisting capacity with a cost of Rs. 8 lakhs or the modemisation of the plant at a cost of Rs. 5 lakhs. The time required forimplementation of both the options is expected to be the same. While considering the demand pattern, he estimates the highdemand situation at a probability of 0.35 as compared to the moderate rise in demand at 0.65 probability. He also estimatesthat he would be spending an additional amount of Rs. 12 lakhs for expansion against Rs. 6 lakhs for modernisation, if thedemand rise is high, whereas in case of moderate demand increase, the expenditure involved would be Rs. 7 lakhs forexpansion or Rs. 5 lakhs for modernisation process. calculate the conditional profits under various combinations |

|
Answer» ong>GIVEN :- The cost of the book is 5 rupees more than twice the cost of a pen. Show this using linear equation by taking Cost of book(x) and cost of a pen(y). Solution :- Let us assume that, cost of book is Rs.x and cost of a pen is Rs.y . given that, → cost of a book = 2 * cost of pen + 5 so, → x = 2 * y + 5 → x = 2y + 5 → x - 2y = 5 . Hence, required linear equation will be x - 2y = 5 . Learn more :- A rectangle having LENGTH of a side is 12 and length of DIAGONAL is 20 then what is length of other side? (A)2 (B) 13 ... |

Find the numbe whis is divisible by 3 a) 224b) 543 c) 2842 |
|
Answer» WER : To CHECK if a number is divisible by 3, we first add the digits then check if it is divisible by 3 or not. If the sum of the digits is divisible by 3 then the number will also be divisible by 3. a) 224 -> 2+2+4 = 8 Sum = 8 which is not divisible by 3. Therefore the number 224 is not divisible by 3. b) 543 -> 5+4+3 = 12 Sum = 12 which is divisible by 3. Therefore the number 543 is divisible by 3. c) 2842 -> 2+8+4+2 = 16 Sum = 16 which is not divisible by 3. Therefore the number 2842 is not divisible by 3. Good Luck... Keep Studying! |
