Simplify the expression. Write the answer using scientific notation.
erik [133]
The answer is 5.88 x 10^22 because when you move your decimal point (which should be placed in between 5 and 8) to the right it turns 58800000000000 into 5.88. Then you count the numbers after the decimal which gives you 12.
( I’m pretty sure I made no sense, but hopefully it helped !! )

Fiona recorded the mean math exam grade for six random samples of students from the entire seventh-grade class. Sample Sample Me
Charra [1.4K]

The reason why Fiona cannot make a valid prediction based on the mean of the population is that the variation of Fiona’s samples is too large.

<h3>Why can't Fiona use the means she recorded?</h3><h3 />

Mean is quite sensitive to outliers so it is best used when the variation between variables is not too much.

In Fiona's case, there variation is quite high with high variable of 95 compared to a low value of 45.
