Using z-scores, it is found that the unusual values are those that are less than 124.
---------------------------
The z-score of a measure X in a data-set with mean 
and standard deviation 
is given by:
- The z-score measures how many standard deviations X is from the mean.
- Measures that are<u> more than 2 standard deviations from the mean</u> are unusual.
- Z < -2 means that the measure X is unusually low.
- Z > 2 means that the measure X is unusually high.
In this problem:
- Mean of 150, thus
. - Standard deviation of 13, thus
.
Unusual values are those that are less than 124.

Given that the pyramid fits perfectly in cube, then the dimensions of the pyramid will be:
height=18 cm
base length =18 cm
thus;
volume=(lwh)/3
l=base length
w=base width
h=height
thus
V=(18×18×18)/3
V=1944 cm³
Answer: C] 1944 cm³
Answer:
It will earn an additional $71.94.
Step-by-step explanation:
First, figure out what 1% of 720 is by dividing 720 by 100 to get 7.2. Then you add 7.2 to 720 to get 727.2. Then you find 1% of the new total and repeat the process.
Answer:
If a scatter plot has no association then it's ordered pairs have no predictable pattern.
Step-by-step explanation:
You need to add all of these values together. This is 2 + 9 + 4 which gives 15
There are 180° in a triangle. Divide this by 15.
180/15 = 12
Then multiply this by the largest in the ratio; which is 9.
This is 12 x 9 which = 108°.
The largest angle is therefore 108°.
For reference, the ratio in degrees would look like this:
24:108:48, which adds up to 180°.
