11.25 and how to find it is: multiply .15 times 75
Answer:
metal as shown. if the cube has sides of length 8 ft, What is the volume of cube after the hole is drilled?
Step-by-step explanation:
shown. if the cube
The base is 4 x 10. which means that you can divide 160 by 40 to get the hieght. (The height is 4)
I'll get you started:
mean = np = (500)(.56) = ?
standard deviation = √npq = √(500)(.56)(.44) = ?
Note: q = 1 - p
Finish the calculations.
To find z-score:
z = (x - mean)/sd
Note: x = 250
Once you have the z-score, look in a z-table using the score to find your probability. Remember that the question is asking "at least 250" when looking at the table.
