Answer:
Step-by-step explanation:
The 90th percentile of a normally distributed curve occurs at 1.282 standard deviations. Similarly, the 10th percentile of a normally distributed curve occurs at -1.282 standard deviations.
To find the percentile for the television weights, use the formula:
, where is the average of the set, is some constant relevant to the percentile you're finding, and is one standard deviation.
As I mentioned previously, 90th percentile occurs at 1.282 standard deviations. The average of the set and one standard deviation is already given. Substitute , , and :
Therefore, the 90th percentile weight is 5.1282 pounds.
Repeat the process for calculating the 10th percentile weight:
The difference between these two weights is .

Answer:
44
Step-by-step explanation:
x + (x+2) + (x+4) + (x+6) + (x+8) + (x+10) = 294
Combine all like terms for x and integers
6x + 30 = 294
Minus 30 on both sides
6x = 264
Divide by 6
x = 44
9514 1404 393
Answer:
second step is wrong; x = 5
Step-by-step explanation:
The correct solution is ...
3(x -3) +9 = 15
3x -9 +9 = 15 . . . . . . . not 3x -3
3x = 15
x = 5

Jeremy did what a lot of students do -- failed to apply the outside factor to <em>all</em> of the terms in parentheses.
The line below are parallel so they have same slopes
If the green line has a slope of -1/2, the slope of the red line is also - 1/2
Answer
-1/2
