Answer:
m∠2 = 113º
m∠3 = 67º
Step-by-step explanation:
m∠2 is supplementary to m∠1, meaning if you add them to m∠1, you will get 180º.
m∠2 + m∠1 = 180º.
m∠2 + 67º = 180º
m∠2 = 113º
m∠1 and m∠3 are vertical angles and are therefore the same.

First, you need to distribute. Multiply the 2 by each number inside the parantheses.
(2*5) - (2*4a) = -33
10 - 8a = -33
Subtract 10 from both sides.
-8a = -43
Divide both sides by -8.
a = 43/8

Well first, you have to simplify the equation: which is: y=6x-2
After that, you have to determine the domain, and most of the time, when you can determine the domain, you have to imagine the graph, and in which you can only find the range that way. In order to find the domain however, you just have to know what restricts x. Like in this problem, there are no numbers that violate the rules of math, and since this equation is a linear problem, the domain and range are both ALL REAL NUMBERS.
The product of a number y and 12 or 12 times a number y. These are both equivalent expressions to 12y
To obtain an estimate of a parameter of a population, we use confidence intervals.
Confidence intervals:
The larger the sample size, the closest the parameter estimate is to the value of the population, as the margin of error of confidence intervals is inversely proportional to the sample size, that is, a greater sample leads to a smaller margin of error.
Thus, you should select the highest sample size in the options.
