A triangle's angles always add up to a total 180º, and a right triangle always has an angle equal to 90º.
90º + 34º + xº = 180º
124º + xº = 180º
xº = 56º
Answer:
45
Step-by-step explanation:
6 × 3 = 18
9 × 3 = 27
18 + 27 = 45
Answer:
I think it's y-y[1] = m(x-x[1])
Step-by-step explanation:
the ones in the parentheses are like smaller near the bottom of the y and/or x btw.
Good luck! :)
A. The point estimate would be the average of the interval boundaries, which is the average of 48.2 and 56.4. This gives a point estimate of 52.3%.
b. The margin of error is the distance from either interval boundary to the point estimate. 56.4 - 52.3 = 4.1%.
c. Assuming this is solely going to be based on the class' decision, their grades should be scored on a curve. Although the margin of error is high and this seems to not have a significant distance from 50%, there is no "middle ground" in this option. We must either grade on a curve or not, and if we must choose one, we have to use to point estimate that is just slightly above 50%.
