Answer: she was not correct, she messed up the equation.
Answer:
The expected frequency for people against the project and who have over 120 feet of property foot frontage is 3.9.
Step-by-step explanation:
The data provided is:
Opinion
Front Footage For Undecided Against Total
Under 45 feet 12 4 4 20
45-120 feet 35 5 30 70
Over 120 feet 3 2 5 10
Total 50 11 39 100
The formula to compute the expected frequency is:

Compute the expected frequency for people against the project and who have over 120 feet of property foot frontage as follows:


Thus, the expected frequency for people against the project and who have over 120 feet of property foot frontage is 3.9.
Answer:
SUPER SORRY IF THIS IS WRONG

Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Answer:
V=a^3
Step-by-step explanation:
The volume of a cube is found by multiplying the length, width, and height. A cube has the same length, width and height. In this case is it 9, so you multiply 9 by 9, three times, obtaining 729, which is your volume.
V=9^3
9x9x9
V=729
