-4x + 3(2x - 5) = 31 (use distributive property to remove parentheses)
-4x + 6x - 15 = 31 (combine like terms)
2x - 15 = 31 (add 15 to both sides)
+15 +15
2x = 46 (divide both sides by 2)
x = 23
Answer:
Step-by-step explanation:
Given that a research institute poll asked respondents if they felt vulnerable to identity theft. In the poll, n=1096 and x=542 who said yes.
i.e. sample size = 
who said yes =
Sample proportion = 
Std error of proportion = 
Margin of error 95% 
Hence confidence interval for proportions
=
a) Point estimate 
B) Margin of error = 
C) Conf interval = 
D) We are 95% confident that for large random samples representing the population, the proportion of yes will lie between these two values.
Answer:
The graph of 3rd picture is correct Option.
Step-by-step explanation:
Let x =green and y = carrots
We make equations of the given sentences and then plot them to find the correct answer.
The equation for A salad made such that the difference between twice the ounces of greens and the ounces of carrots is at least 3 is
2x-y ≥ 3
The equation for the sum of the ounces of greens and twice the ounces of carrots is less than 4.
x+2y < 4
We plot both the equations and gain the graph.
The graph is attached in the figure.
The graph of 3rd picture is correct Option.
