Answer:
About 48 members would be expected to say that dues be raised
Step-by-step explanation:
Here, we shall be using a case of a representative sampling to determine the actual.
Out of the 100 selected members, 6 said the dues should be raised;
This represents a percentage of 6/100 = 6%
So out of the 800, the expected number of members that would ask for a dues raising will be;
6/100 * 800 = 48
For this case we have the following equation:

From here, we must clear the value of y.
For this, we follow the following steps:
1) Distributive property:

2) Variable terms on one side of the equation and constant terms on the other side of the equation:

3) Algebraically add the constant terms:

4) Pass the number 20 to divide:

Answer:
The value of y is given by:

What do you mean put in standard form?
Answer:
a=75
Step-by-step explanation:
85^2-40^2=5625
then the square root of that is 75
