1 foot = 12 inches
12 * 5 = 60 and 8 * 12 = 96
Therefore, 60 inches is a shorter length than 8 feet.
Answer:
- <u>The correct statement is the first one: </u><u><em>The number of blue-eyed students in Mr. Garcia's class is 2 standard deviations to the right of the mean</em></u><em> </em>
<em />
Explanation:
To calculate how many<em> standard deviations</em> a particular value in a group is from the mean, you can use the z-score:
Where:
- is the number of standard deviations the value of x is from the mean
- is the mean
- is the standard deviation
Substitute in the formula:
Which means that <em>the number of blue-eyed students in Mr. Garcia's class is 2 standard deviations</em> above the mean.
Above the mean is the same that to the right of the mean, because the in the normal standard probability graph the central value is Z = 0 (the z-score of the mean value is 0), the positive values are to the right of the central value, and the negative values are to the left of the central value.
Therefore, the correct statement is the first one: <em>The number of blue-eyed students in Mr. Garcia's class is 2 standard deviations to the right of the mean, </em>
<span>You have to apply the rule to the XYZ coordinates, so
X'= (-2-1, 1+3)
Y'= (-4-1, -3+3)
Z'= (0-1, -2+3)
So the new coordinates are X' (-3, 4), Y' (-5, 0), and Z'(-1, 1)
This is actually translation not transformation, as the shape doesn't change it just moves</span>
The easiest way is just to plug it in to your calculator. you find the square root button and plug the number in. for example if you plug in the square root of 289 you get 17
The correct answer is 8.
Hope this helped!
