Answer:
I guess the best answer is 10
Step-by-step explanation:
because 20-10 is 10
Let one of the numbers be x. The other number cab then be represented as 36-x (x+36-x = 36).
The product can then be represented as y = x(36-x) or y=36x-x2
The maximum or minimum is always on the axis of symmetry which has the formula x=-b/2a.
In our case, the axis of symmetry is -36/-2, so x=18.
If one number is 18 and the 2 numbers add to 36, the other number is 18 as well.
So the 2 numbers are 18 and 18 and the maximum product is 324,
1. A) 5 (It would be B. because it does equal 4.09 but it has to be 5 because it is the greatest integer in all of them)
2. D) 10 (Just like 1. it would be B. also BUT 10 is the greatest integer you can have out of all of them)
3. A) 6 (Just like the other 2 problems at the top^ it would be C. if not for the fact it has a higher number.)
4. A) A value we can put in place of a variable (such as x) that makes the equation true.

A) 2.6 mm Hg
Step-by-step explanation:
Margin of error = critical value × standard error
ME = CV × SE
n > 30, so we can approximate CV with a normal distribution. At P = 94%, CV = 1.88.
SE = σ / √n
SE = 13.5 / √92
SE = 1.41
So the margin of error is:
ME = 1.88 × 1.41
ME = 2.6
