Answer:
Hey!
Step-by-step explanation:
I got this off the internet for you.
In statistics, the standard deviation (SD, also represented by the Greek letter sigma σ or the Latin letter s) is a measure that is used to quantify the amount of variation or dispersion of a set of data values.
Hope this helps! :)
Have a nice day♥
 
        
             
        
        
        
Answer:
A
Step-by-step explanation:
the height a creates with half of the baseline (5) and a leg (10) a right-angled triangle, and we can use Pythagoras to calculate a.
c² = a² + b²
c being the Hypotenuse (the side opposite of the 90° angle, so in our case the 10 side).
10² = a² + 5²
100 = a² + 25
75 = a²
a = sqrt(75) = sqrt(3×25) = 5×sqrt(3)

        6.2
<u>x    0.0</u><u>3</u>
            6
     1
        6.2
<u>x    0.0</u><u>3</u>     since 6*3=18, we have to carry the 1
         86

        186
        6.2
<u>x    0.</u><u>0</u><u>3</u>

         186
+      00            add the partial products

      00186
       6.2
<u>x    0.</u><u>03</u><u>     </u>                   count how many digits are after the decimal point      from each factor =3 and place in product
         186
+      00

Answer:
is this the right question please??
 
        
             
        
        
        
B
The answer is b. Because you x can be a negative, but you’re squaring it so it will equal a positive, and if you add 4, it is still 4 or greater
