Answer:
Step-by-step explanation:
One way to solve the quadratic equation x2 = 9 is to subtract 9 from both sides to get one side equal to 0: x2 – 9 = 0. The expression on the left can be factored: (x + 3)(x – 3) = 0. Using the zero factor property, you know this means x + 3 = 0 or x – 3 = 0, so x = −3 or 3.
Given:
The given sum is:
To find:
The expanded form and find the sum.
Solution:
We have,
The expanded form of given sum is:
Therefore, the correct option is C.
Answer:
0.05 is 5/100, while 0.5 is 50/100 (or 5/10 or 1/2)

Answer:
(7.7981, 8.5419). The distribution of percentage elongation can be any distribution with finite mean and variance.
Step-by-step explanation:
We have a large sample size n = 56 research cotton samples. Besides, 
and 
. A 95% large-sample CI for the true average percentage elongation is given by 
, i.e., 
or equivalently (7.7981, 8.5419). The distribution of percentage elongation can be any distribution with finite mean and variance because we have a large sample.
243,880 is the correct answer
