Answer:
1 7/8
Step-by-step explanation:
1/4=2/8
2+2/8-3/8= 1 7/8
1 step: Place the point of the compass on point M and draw an arc, making sure the width of the compass opening is greater than 1/2MN.
2 step: Place the point of the compass on point N and draw an arc that has the same radius as previous one.
3 step: Connect two points of intersection of drawn arcs. Obtained line will be bisector.
Answer: option D.
We know that:
Mean = 82 mm and SD = 10 mm ( standard deviation )
82 - 3 * SD = 82 - 3 * 10 = 82 - 30 = 52 mm
82 + 3 * SD = 82 + 3 * 10 = 82 + 30 = 112 mm
Population between 52 and 112 mm is within +/- 3 standard deviations from the mean.
By the 66- 95 - 99.7 % rule it is: 99.7% of the test group.
0.977 * 500 = 498.5
Answer:
99.7 % of the test group have a diastolic pressure between 52 and 112 mm, or 498 men.
