Answer:
97.6% of the trees will have diameters between 7.6 and 18.6 inches.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 12 inches
Standard Deviation, σ = 2.2 inches
We are given that the distribution of diameter of tree is a mound shaped distribution that is a normal distribution.
Formula:

P(diameters between 7.6 and 18.6 inches)

97.6% of the trees will have diameters between 7.6 and 18.6 inches.
Answer:
none of the above
Step-by-step explanation:
because 5p + 3p = 8p and positive integers × negative integers = negative integers.
??? what type of question is that??
2(4x-3)-7(x+1) first distribute
8x-6-7x+7 then combine the x's
<u>x+13 </u>
I think the answer is D) 8 over 32 multiplied by 7 over 31
Hopefully that helped! :)
