Answer:
B) 47.5%
Step-by-step explanation:
Refer to the normal distribution chart attached. If 130 is 2 standard deviations higher than the mean (ignore the numbers beneath the percentages), then by the empirical rule, this means that 34%+13.5%=47.5% of adults are between IQs of 100 and 130. Therefore, option B is correct.
Given the image attached, the segment bisector that divides XY into two and the length of XY are as follows:
<em><u>Recall:</u></em>
In the diagram attached below, line n divides XY into XM and MY.
Thus, the segment bisector of XY is: line n.
<em><u>Find the value of x:</u></em>
XM = MY (congruent segments)
XY = XM + MY
Therefore, given the image attached, the segment bisector that divides XY into two and the length of XY are as follows:
