Below is the normal distribution curve for height (inches) of NBA basketball players.
VladimirAG [237]

Answer:  standard deviation = 8

This is because mu = 75 is the mean, which is at the very exact center of this distribution. One space to the right is 83, which is 83-75 = 8 units away from the center. This distance is exactly one standard deviation. We can say "83 is one standard deviation larger than 75".

Or you could note the distance from 67 to 75 is also 8, because 75-67 = 8. Each tickmark represents stepping one standard deviation in distance.

Find the value of 4²+6÷2
belka [17]

The answer is:    " 19 " .

_____________________

Explanation:

To solve:

_____________________

Given:

" 4² + 6 ÷ 2 " ;

We solve using "PE MD AS" (mnemonic device for order of operations in order of consideration);  which stands for:

           "Please Excuse My Dear Aunt Sally (or Aunt Susan)" ;

Alternately:  "BE MD AS"  

           " Be Excused My Dear Aunt Sally (or Aunt Susan)" .

                         "Parentheses {alternative version:  "Brackets" ; in which "Parentheses can be considered "Brackets" ; yet in reality, Brackets would come before Parentheses}, then Exponents, then "Multiplication then Division (from left to right as they occur in the problem) , then "Addition then Subtraction (from left to right as they occur in the problem) .

_____________________

As such:  

Given:   " 4² + 6 ÷ 2 " , we have:  

"exponents", "addition" and "division" ;

So we can rewrite the problem as:

   "  (4²) + (6 ÷ 2) =

      (4 * 4) + (3)  =

       (16)   +  (3)  =  19 .

_______________________

The answer is:    " 19 " .
