A solution to a system of equations is a set of values for the variable that satisfy all the equations simultaneously. In order to solve a system of equations, one must find all the sets of values of the variables that constitutes solutions of the system.
Answer: 0.0125
Step-by-step explanation:
Given : A survey by the Pew Research Center asked a random sample of 2142 U.S. adults and a random sample of 1055 college presidents how they would "rate the job the higher education system is doing in providing value for the money.
5% the U.S. adults and 17% of the college presidents provided a rating of "Excellent."
i.e. 
, 
The standard error of the difference in sample proportions :-
Hence, the standard error of the difference in sample proportion = 0.0125
13.45 x $4.30= $57.835 ≈ $57.84
13.45 x 40.2=540.69 miles
Answer:
16 ft²
Step-by-step explanation:
Since we're told that 2 ft diameter was cut of the board. We use the formula for hollow circle to find the area.
Area of remaining body = area of full body - area of removed body.
Area = πd²/4
Area of remaining body = (π * 5²)/4 - (π * 2²)/4
Area of remaining body = 19.64 - 3.142
Area of remaining body = 16.49 ft²
Therefore, the remaining area is then calculated into 16 ft²
That mean the awner to question is 3 y is 3 just substract 6 minus 3
