Answer: C and D
Explanation:
Is it A? No, because a right triangle does not have all three sides with equal length. Only in a equilateral triangle will have all three equal sides of equal length.
Is it B? No, because a triangle has ZERO parallel lines. Remember parallel lines are like this | | in a triangle the lines are like this /\
Is it C? Yes, because a triangle has two sides of equal length, meaning it has two congruent sides.
Is it D? Yes, a right triangle has two sides that create the 90 degrees making it a right triangle. Perpendicular means that theirs two lines creating the 90 degree and a triangle has two perpendicular sides.
Answer:
out of the entire piece 160/200 is shaded, after simplifying it should be 4/5
Step-by-step explanation:
count the total, in this case 200 blocks
then count the shaded area, 160
160/200 --> after simplifying --> 4/5
Answer:
A.) y=3x-1
Step-by-step explanation:
Point-slope form can be shown using the equation: y = mx+b
In this case, m is slope, and b is the y-intercept.
Slope in this graph can be found by finding the rise over the run, or the number of blocks the line moves vertically over the number of blocks the line moves horizontally. The line moves at a rate of 3 blocks up for every 1 block to the right, or 3/1. That means that the slope is 3.
The y-intercept is wherever the line crosses the y-intercept, or wherever x equals 0. This happens at y = -1.
If you plug the slope (3) and the y-intercept (-1) into the equation y = mx+b, you get y = 3x-1.

Step-by-step explanation:
Answer:
Margin of errors, in statistics, is the degree of error in results received from random sampling surveys. A higher margin of error in statistics indicates less likelihood of relying on the results of a survey or poll, i.e. the confidence on the results will be lower to represent a population.
