The answer is:
Both have the same number of data points
Both means are between 3 and 4
Westwood has less variability than Middleton
Answer:
Step-by-step explanation:
you would use the distributive property, so the answer should be..... -377/1015, OR -13/35 BTW i'm not completely sure this is correct. Im not a calculator. But I think Im correct
There are many ways in which we can find for the zeros of the problem. We can use the quadratic formula, completing the square, using a graphing calculator, etc.
For this problem, I'll be completing the square.
x² - 6x = -22
Since the constant has been moved to the right side already, we can move on to the next step which is adding (b/2)² to both sides of the equation.
x² - 6x + (-6/2)² = -22 + (-6/2)²
x² - 6x + 9 = -22 + 9
Factor the left side of the equation into a perfect square and simplify the right side.
(x - 3)(x - 3) = -13
Take the square of both sides.
x - 3 = ± √-13
Take out the negative from the square root as the letter "i"
x - 3 = ± i√13
Add 3 to both sides of the equation to let x be by itself.
x = 3 ± i√13
So your two roots will be:
x = 3 + i√13 and x = 3 - i√13
Solution: C. 3 - i√13
The giraffe (using the ruler) is 11 cm.
1 cm : 50 cm
Multiply both sides by 11.
11 cm : 550 cm
There are 0.01 meters in 1 centimeter.
Multiply 550 cm by 0.01.
(550)(0.01) = 5.5
The giraffe's real length is 5.5 meters.
