Answer:
We are 95% sure that the true proportion of students that supports a fee increase is between 0.75 and 0.85.
Step-by-step explanation:
The interpretation of a x% confidence interval of proportions being between a and b is that:
We are x% sure that the true proportion of the population is between a and b.
If the 95% confidence interval estimating the proportion of students supporting the fee increase is (0.75; 0.85), what conclusion can be drawn
We are 95% sure that the true proportion of students that supports a fee increase is between 0.75 and 0.85.

Answer:
5/7
Step-by-step explanation:
We need the Pythagorean Theorem here.
If you have a right triangle, you can use the equation a^2+b^2=c^2 where a and b are legs and c is the hypotenuse.
Plug in your information.
(3/7)^2+(4/7)^2=c^2
Simplify what you can.
9/49+16/49=c^2
25/49=c^2
Square root both sides.
5/7=c
