1. draw a histogram from all the data. starting at the bottom row, for each set of 10 flips, place an "x" in the column
corresponding to the number of heads that set produced. your histogram should look similar to the example below:
number of heads
x
4
x x
5 6
x
7
x
8
0
1 2
3
9 10
flo set
number of heads in 10 flins
2. calculate the mean and standard deviation
mean = standard deviation =
3. calculate the percent of the data that is within 1, 2, and 3 standard deviations of the mean.
_%
1. within 1 standard deviation =
2. within 2 standard deviations =
3. within 3 standard deviations =
4. compare your results to a normal distribution. interpret any differences.

x/7.50 = 15

x= 7.50 / 15 divide

step-by-step explanation:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

answer: y=0 if that is what u r looking for

i recommend you do what your heart desires. if you're attracted to the same gender, then you're attracted to the same gender. you can't determine what your heart wants.
