Answer: (0, 1) Usually, we put the solutions in parenthesis.
Step-by-step explanation: x(x+1) = x(2) which = x²+ x = 2x = x² + x - 2x = 0
x² - x = 0. Now we divide by x which = x(x - 1) = 0 and the new solution set is x = 0 and x -1 = 0 which equals x = 1
Answer:
The 95% confidence interval estimate of the proportion of people who say that they voted
(0.67122 , 0.72798)
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
In a recent survey of 1002 people, 701 said that they voted in a recent presidential election.
Sample proportion
<u><em>Step(ii)</em></u>
The 95% confidence interval estimate of the proportion of people who say that they voted
(0.6996 - 1.96 X 0.01448 , 0.6996 + 1.96 X 0.01448)
(0.6996 - 0.02838 , 0.6996 + 0.02838)
(0.67122 , 0.72798)
<u><em>Final answer</em></u>:-
The 95% confidence interval estimate of the proportion of people who say that they voted
(0.67122 , 0.72798)
The answer is answer choice B,
B) {-2, -1, 0, 1}

Y=90x+2,000
90 is the rate of change because the hot air balloon descends 90 feet per minute.
And 2,000 is the starting point because the hot air balloon started the descent at 2,000 feet.

Answer:
3
Step-by-step explanation:
For f(x) = x^3 -2x^2 -7x +5 and x=1/(2-√3), we have ...
f(x) = ((x -2)x -7)x +5
and ...
x = 1/(2-√3) = (2+√3)/(2^2 -3) = 2+√3
Then ...
f(2+√3) = ((2 +√3 -2)(2 +√3) -7)(2 +√3) +5
= (3+2√3 -7)(2+√3) +5
= 2(√3 -2)(√3 +2) +5 = 2(3 -4) +5 = -2 +5
f(1/(2 -√3)) = 3
_____
If you really mean x = (1/2) -√3, then f(x) = (42√3 -3)/8.
