Step-by-step explanation:
Given,
Mean, 
minutes,
Standard deviation = 
minutes,
Let x represents the run time,
Thus, the probability of students who could run a mile in 7 minutes or less
= P( x ≤ 7 )
By the normal distribution table,
Hence, the proportion of students who could run a mile in 7 minutes or less is about

Answer:
Connect the intersections of the diameters and the circle with a segment
Step-by-step explanation:
Assuming the construction creates two orthogonal diameters, their ends will be the vertices of the inscribed square. Connecting them with segments in order around the circle will create the square.
The true statement about her method would be to start at the origin. But you would go up 4 spaces you would go to the right 4 spaces.
