Question

A die is a cube with the numbers 1, 2, 3, 4, 5, and 6 written on its six faces,one number per face. A die is rolled 12 times. Here are the faces that show: 6, 3, 1, 6, 3, 5, 3, 1, 2, 1, 3, 2.
Which face was the mode?

Answer 1

do you know the definition of mode ?

Answer 2

The mode in a list of numbers refers to the number that occurs most frequently.

Answer 3

The mode is not necessarily unique

Answer 4

remember Mode is MOST

Answer 5

if there is a tie for most, then all the numbers in the tie can be called the mode.

Answer 6

one way is sort the list.
I think 3 is the only mode (if I counted correctly)

Answer 7

3 repeats 5 times

Answer 8

there are 5 3's so it is the mode (3 occurs most often in the data)

Answer 9

mode = 3, number of modes =1

Answer 10

number of modes was asked, so answer =1

Answer 11

add all them, thats sum
count how many numbers are there, that 'n'
average = sum/n

Answer 12

let me calculate

Answer 13

yes, thats correct.

The stem and leaf plot below shows the distribution of weights (in ounces) of newborns at a hospital. The line 10 | 358 should be read as 103, 105, 108. Select the option that is closest to the average of these weights. Yes, you can enter the list into your calculator and compute the average. But it will be a lot faster to do this exercise by inspection.

9 | 2

10 | 358

11 | 034445559

12 | 002258

13 | 12678

14 | 013446

Answer 15

there are so many weights!

Answer 16

what are your choices ?

Answer 17

idk how to do it with inspection..with calculator, it'll take many minutes!

Answer 18

i can guess it to be 125

Answer 19

i can't be sure because i don't know how to do it with inspection, but since there were many numbers with "11. ",the average has to be near 110 or greater, so i guessed 125

Answer 27

As part of a fund raising campaign, the 12 members of the governing board of an organization pledge to raise $100,000. In the first month of the campaign, the average amount raised by the 12 board members is $5,200. How much more must they raise, on average, so that they can keep their pledge?

[Answer format: Your answer will be interpreted as dollars and cents. If you think the answer is $12.34, enter 12.34]

Answer 28

total raised = 12*5200
remaining = 100000-12*5200

Answer 29

average = remaining/12

Answer 30

remaining = 100000-12*5200=37600
average = 37600/12 = 3133.34
is this an option ?
