The weighted average of the numbers -1 and 1, with weight 2/3 on the first number and 1/3 on the second number is 0.33
What is weighted average?
Weighted average is the sum of the two numbers multiplied by their respective weights, in other words, the weighted average can be determined using the below formula :
Weighted average=(first number*its weight)+(second number*its weight)_
weighted average=(1*2/3)+(-1*1/3)
weighted average=0.33

Third option I believe sorry if I’m incorrect
This looks like: 
To solve this problem, you'll want to use the AC method to factor x^2+7x-30.
After factoring your expression will look like this:
Cancel out the x+10 because they are common factors, so you are just left with the simple x-3.
Answer is:
x - 3

Answer:
No, the height cannot be 25 feet because the resulting area is inconsistent with the information given.
Step-by-step explanation:
Given that the base of the first floor is 75 feet, we can answer this question in two different ways:
1) Solve for Area using the given height and compare the results to that of the question.
Using the formula for Area:
<em> A = b x h,</em>
<em>A = (75) x (25) = </em><em>1875 </em>
Because the given height results in an area of 1875 feet, and not 1575 feet, the base of this parallelogram cannot be 25 feet.
2) Solve for Height using the given base and Area
Using the formula for Height:
<em>h = A / b,</em>
<em>h = (1575) / (75) = </em><em>21</em><em> ft</em>
The base of this parallelogram could not be 25 feet because when solving for height using the given base and area, the resulting measurement is 21 feet.
