What is the question here that I should answer?
6x^2 +30x - 36
6( x^2 +5x -6)
6(x^2 -x+6x-6)
6[ x(x-1) 6(x-1)]
(x-1) (x+6)
Both are similar, so Yes.
-All the sides of the squares are equal
-The triangles are also the same, just one is smaller. The one on the right is 2/3 of the one on the left.
Answer: The required confidence interval would be (2.72,2.89)
Step-by-step explanation:
Since we have given that
Mean = 2.8 pounds
Standard deviation = 0.24 pounds
n = sample size = 16
We need to find the 80% confidence interval for the mean waste.
z=1.341
So, the confidence interval will be

Hence, the required confidence interval would be (2.72,2.89)
