I don't really like these algebra problems which pretend to be geometry.

The bisector makes two equal angles, so

x/2 + 17 = x - 33

50 = (1/2) x

x = 100

That means ABC = 100/2 + 17 = 67 degrees

CBD = 100 - 33 = 67 degrees, equal so that checks

We're asked for ABC which is 67 + 67 = 134 degrees

Answer: 134°

What is the equation of the line of the best fit for the following data? Round to the slope and y-intercept of the line to three

BigorU [14]

Answer:

D. $y=-0.927x+13.634$

Step-by-step explanation:

We graph the points on the graph. The graph is attached.

Let us take two points (1, 14) and (15, 1), and calculate the slope $m$ between them <em>(we choose these points because the line passing through them will be the best fit for all points) </em>

$m=\frac{14-1}{1-15} =\frac{13}{-14} =-0.9286$

Thus we have the equation

$y=-0.9286x+b$

Let us now calculate $b$ from the point $(1,14)$

$14=-0.9286(1)+b$

$b=14.9286$

So the equation we get is

$y=-0.9286x+14.9286$

Let us now turn to the choices given and see which choice is closest to our equation: we see that choice D. $y=-0.927x+13.634$ is the closest one, so we pick it.

fredd [130]

Answer: a. statistic

Step-by-step explanation:

Population : It is a set of all possible observations that can be made regarding a study by the researcher.
Sample : It is finite subset of population that represents the population in the researcher's analysis.
Population parameter : It is a value that is calculated from the entire population such as population mean , population proportion etc.
Statistics : It is a value that is calculated from the sample taken out from population.

Since ,The group of people who took poll are representing the sample.

Therefore, 92% of those polled said that a year from now their family financial situation will be as good as it is today or better that means 92% describes a statistics.

Thus , the correct answer is a. statistic
