In cynthia's physics class, she must turn in four lab reports. for each report, she earns extra credit if her percent error is less than 5%.
for her second lab report, she calculated the height of a building four times. she got the following four heights.
6.8 m
7.5 m
8.1 m
7.8 m
the true height of the building is 7 m.
what was cynthia's percent error?
remember: take the average of the three measurements before calculating the percent error.
about 8%
about 7%
about 6%
about 5%

i think the answer is seven, for if i'm being useless °ω°

step-by-step explanation:

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
