Answer:
2
Step-by-step explanation:
200=4(5)(9)+2(5)h
Simplify:
200=20(9)+10h
200=180+10h
Subtract 180 on both sides:
20=10h
Divide by 10:
h=2
Answer:
The top 30% is defined with a score greater than or equal to 431.44 so she will not be admitted (D)
Step-by-step explanation:
Mean m = 400
Standard deviation S = 60
Firstly, we have to determine the cut off mark,
Since Only students who score in the top 30% are accepted, the cut off mark can be determined from 70% of the mark.
P(cut off mark = X) = Z[( X -m)/S) <x]
=¢(X-400/60) = 0.7
From Normal distribution table,
X-400/60 = 0.524
X = 431.44
Therefore, the cut off mark is 431.44
Since Amy scores 425 on the test.
Therefore, The top 30% is defined with a score greater than or equal to 431.44 so she will not be admitted (D)
