i think its 2 workers, ill delete this if its wrong:/
Step-by-step explanation:
Simplifying
3x + 25 = 2x + 20
Reorder the terms:
25 + 3x = 2x + 20
Reorder the terms:
25 + 3x = 20 + 2x
Solving
25 + 3x = 20 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
25 + 3x + -2x = 20 + 2x + -2x
Combine like terms: 3x + -2x = 1x
25 + 1x = 20 + 2x + -2x
Combine like terms: 2x + -2x = 0
25 + 1x = 20 + 0
25 + 1x = 20
Add '-25' to each side of the equation.
25 + -25 + 1x = 20 + -25
Combine like terms: 25 + -25 = 0
0 + 1x = 20 + -25
1x = 20 + -25
Combine like terms: 20 + -25 = -5
1x = -5
Divide each side by '1'.
x = -5
Simplifying
x = -5
Answer:
Population = All registered voters in Raleigh city
Population size = 9500
Sample size = 360
Proportion of sample statistic for brown = 0.3167
3008 voters
Step-by-step explanation:
Population refers to all elements which meets the requirement for a specific experiment or research interest.
Number of voters for brown = 114
Number of voters for Feliz = 210
Undecided = 36
Sample statistic for proportion in support of brown :
Proportion = x / n
x = number who said they'll vote for brown
n = sample size
Sample statistic for proportion in support of brown = 114 / 360 = 0.3167
Using the proportion ; number from population who'll vote brown :
Sample proportion * population size
0.3167 * 9500 = 3008 voters
