Answer:
The probability that a randomly selected student has a score between 350 and 550 = 0.5867
Step-by-step explanation:
Mean
= 500
Standard deviation
= 110
Let X be the score of student in a standardized test
The probability that a randomly selected student has a score between 350 and 550 =
= 
=
Putting 
= 
= 0.6736 - .0869 ( Using Z table )
= 0.5867
Answer:
Slope = -⁵/3
Step-by-step explanation:
See the attachment below. In the attachment, the green line represents the the rise while the red line represents the run of the line.
The slope = rise/run
Rise = 5
Run = 3
Slope = -(5/3)
Slope = -⁵/3 (the slope would be negative because the line slants downwards from your left to the right)
Answer:
<em>About 900 cans not stamped in 3 hours</em>
Step-by-step explanation:
<u>Proportions</u>
Sally found that 150 cans were not stamped in the 1/2 hour trial run.
Following the same proportion in time, we can say:
150 cans not stamped in 1/2 hour. Multiplying by 2:
300 cans not stamped in 1 hour. Multiplying by 3:
900 cans not stamped in 3 hours
About 900 cans not stamped in 3 hours
