I need help with these questions!?

Question

1. How are all graphs alike? How are frequency tables, bar graphs, and histograms different?



2. Find the mean, median, mode and range of the following data?



13, 13, 24, 24, 25, 25, 31, 31, 31, 40



3. Use the data from question number 2, identify the upper and lower extremes to use in a Box-and Whiskers plot?



4. What is the probability of rolling a number 3 or less on a die (cube with the numbers 1 ? 6) on it? State your answer as a percent.



5. A school class contains 12 girls and 10 boys. The teacher randomly calls on a student. What is the probability that the student is not a girl? State your answer as a fraction in lowest terms.



6. Suppose there are two spinners. One spinner is half read and half black. The other spinner has 3 equal sections labeled 1, 2, 3. Find the probability of spinning read on the first spinner and ? 1 ? on the second spinner.



7. Suppose a bag contains 10 marbles. All marbles are the same size. One marble is red, two are green, three are blue and four are black. A marble will be taken from the bag two times. Each time a marble is taken out; it is replaced. What is the probability of drawing a red and green marble?



8. Assume you have the same bag of marbles as in question # 7 above. What is the probability of drawing a black marble each time?



9. Choose any four letters of the alphabet. How many different ways can those four letters be arranged?



10. There are five crayons each a different color in a box. How many different ways can those five crayons be put into the box?

Answer 1

LOL you suk at math :P

Answer 2

1. All graphs are alike because they all represent data in a readable form.



2. Mean - 29.6

Median - 25

Mode - 31

Range - 37



3. 24 and 31 are the 1st and 3rd quartile, 13 and 40 are the extremes



4. 50%



5. 5/6



6. probablity of first spinner x probablitity of second spinner = 1/2 x 1/3 = 1/6



7. 1/50



8. 4/25



9. 24



10. 120

Answer 3

graphs diagrams that exhibits a relationship, often functional, between two sets of numbers as a set of points having coordinates determined by the relationship. Also called plot.

A pictorial device, such as a pie chart or bar graph, used to illustrate quantitative relationships. Also called chart.

To find the range, you simply subtract the smallest number from the largest number in the set

To find the mean you add up all the numbers and divide the answer by how many numbers you have.

The Median is the number which is in the exact middle of the data set.

The Mode is the number that appears the most often

3. The lower quartile is the median of the set of data below the median (not including the median). The upper quartile is the median of the set of data above the median (again not including the median).

number of ways to roll a 3 = 1 /6

total number of sides

2/6

P(yellow) = number of ways to land on yellow = 1

total number of colors 4

P(blue) = number of ways to land on blue = 1

total number of colors 4

P(green) = number of ways to land on green = 1

total number of colors 4

P(red) = number of ways to land on red = 1

total number of colors 4



P(red) = number of ways to choose red = 6 = 3

total number of marbles 22 11

P(green) = number of ways to choose green = 5

total number of marbles 22

P(blue) = number of ways to choose blue = 8 = 4

total number of marbles 22 11

P(yellow) = number of ways to choose yellow = 3

total number of marbles 22



look above

Answer 4

i ought to ought to in ordinary words say no, I propose, if someone won't be able to take hairspray or a bottle of shampoo on board those days i ought to ought to imagine that a metal merchandise would not be allowed both. Grrrr! (((Go8tm))) Dangit! I used all my brains cells contained in the awesome question, i'm clueless! Yeah, i understand, large wonder, lol! : / allow me take yet another wager, is it lead from a pencil? Lol, this little pencil is searching at me in this field speaking about "Oops! It feels like you've 4 misspelling(s). HA! No i do not,..do I? question,...Can it reflect something like mild or regardless of?

Answer 5

okay. you should look in your math book or look online on a weebsite. or ask someone older than you... like your parents ir a sibling! ill give you a hint- the mode is the number that appears most!

median- the number in the middle

range biggest number - smallest number

mean is the average

Answer 6

2.25+25/2=median

mean=add everything/the total no. of observations

mode=the no coming maximum times over here 31 is the mode





well dear i can help but it will take a lot of time refer guides ur notes and reader

Answer 7

the answer to the 9 th question is 4!

24

the rest u have to do it urself hun

nobody is doing it for ya in the exam
