120+120+192=432 is the area
Answer:
No solution.
Step-by-step explanation:
Eliminate the equal sides of each equation and combine.
-4x-5=-4+5
Solve -4x-5=-4x+5 for x by moving all terms containing x to the left side of the equation. Add 4x to both sides of the equation.
-4x-5+4x=5
Combine the opposite terms in -4x-5+4x.
Add -4x and 4x.
0-5=5
Subtract 5 from 0.
-5=5
Since -5=5, there are no solutions.
the answer to the function would be 37 because w(7) shows that the variable would equal 7. So 5x7 would equal 35 plus 2 would give you 37.
Answer:
(820 ; 980)
Step-by-step explanation:
Given :
Sample size, n = 80
Number of bilingual from sample = 36
Sample proportion, phat = x / n = 36 / 80 = 0.45
Margin of Error = 4% = 0.04
Interval = sample proportion ± margin of error
0.45 ± 0.04
(0.41 ; 0.49)
(0.41 * 2000 ; 0.49 * 2000)
(820 ; 980)
