Answer: 80
Step-by-step explanation: took the test
Mean diameter = 25 mm
Standard deviation = 0.2 mm
25.6 mm - 25 mm = 0.6 mm
0.6 mm : 0.2 mm = 3
Answer:
A ball bearing with a diameter 25.6 mm differs from the mean
D ) 3 standard deviations.
-7t+3>-46
Subtract 3 on both sides to cancel it out.
-7t+3>-46
-3 -3
-7t>-49
Now divide -7 on both sides.
-7t>-49
/-7 /-7
t>7
This means the answer, or t, can be anything above 7.
