Answer:
The correct answer is Approximately 6-10 pounds
Step-by-step explanation:
According to the given statement a toy American Eskimo dog has a mean weight of 8 pounds with a standard deviation of 1 pound
According to normal distribution 95% dogs lie between 2 std deviation on either side of the mean.
Therefore lower bound = 8-2 = 6
Upper bound = 8+2 = 10
Thus the range would be approximately 6–10 pounds ....
Let's solve this problem step-by-step.
−3(1−2x)=3x+3(x−3)+6
Step 1: Simplify both sides of the equation.
−3(1−2x)=3x+3(x−3)+6
(−3)(1)+(−3)(−2x)=3x+(3)(x)+(3)(−3)+6(Distribute)
−3+6x=3x+3x+−9+6
6x−3=(3x+3x)+(−9+6)(Combine Like Terms)
6x−3=6x+−3
6x−3=6x−3
Step 2: Subtract 6x from both sides.
6x−3−6x=6x−3−6x
−3=−3
Step 3: Add 3 to both sides.
−3+3=−3+3
0=0
So, 0=0 or all real numbers.

The diagram does illustrate x²+6x+9=72. This is also represented by
(x+3)² = 72
We can take the square root of both sides:
When we evaluate this, the answers are x = -11.5 or x = 5.5.
