The brain volumes ​(cm cubed ​)
of 50 brains vary from a low of 908

cm cubed

to a high of 1492

cm cubed
.
Use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 176.5

cm cubed
​,
assuming the estimate is accurate if it is within 15 cm cubed
.

where is the rest of the

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
