About 68% of sixth-grade students will have heights between inches and inches.

About 68% of sixth-grade students will have heights between 55.7 inches and 60.3 inches.

Step-by-step explanation:

The Empirical rule, also the 68–95–99.7 rule, states that for a population that is approximately normal or symmetrical, nearly all of the data values will lie within three standard deviations of the mean;

68% of data values will fall within one standard deviation from the mean

95% of data values will fall within two standard deviation from the mean

99.7% of data values will fall within three standard deviation from the mean

Now, assuming the heights of the sixth-grade students are approximately normal 68% of these students will have their heights fall within one standard deviation from the mean;

mean ± standard deviation

58 ± 2.3 = (55.7, 60.3)

Therefore, about 68% of sixth-grade students will have heights between 55.7 inches and 60.3 inches.

angles 1 and 3 are vertical angles, meaning that they are equal to each other. to solve this you may set angle 1 and 3 equal to each other and just solve for x like

110 = 2x + 10

100 = 2x

50 = x

check:

110 = 2* 50 + 10

110 = 100 + 10

110 = 110

hope this !
