I did the calculations two ways. The last data item was 185.00!
I wasn't sure if this was correct or a typo. With 185.00: mean 33.31. STD dev 53.68. With 185.00 changed to 18.50: mean 14.81 std dev 2.75
Product= the result of two numbers being multiplied together.
Sum= the result of adding numbers.
Integer= a whole number in the set of numbers containing zero, the natural numbers, and all of the negatives of the natural numbers.
factor x2-12x+35 using the AC method.
Consider the form x^2+bx+c. Find a pair of integers whose product is c and whose sum is b. in this case, whose product is 35 and whose sum is -12.
-7,-5
c) (x-5) (x-7)
<span>Simplifying
X2 + -4 = 0
Reorder the terms:
-4 + X2 = 0
Solving
-4 + X2 = 0
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + X2 = 0 + 4
Combine like terms: -4 + 4 = 0
0 + X2 = 0 + 4
X2 = 0 + 4
Combine like terms: 0 + 4 = 4
X2 = 4
Simplifying
X2 = 4
Take the square root of each side:
X = {-2, 2}</span>
