dimulka [17.4K]

Answer: (-11,-14)

Step-by-step explanation:

3 units left means you subtract 3 from the x-value and 5 units down means you subtract 5 from the y-value. So -8-3=-11 and -9-5=-14. So the answer is (-11,-14)

The long-distance calls made by the employees of a company are normally distributed with a mean of 6.3 minutes and a standard de
Sergio [31]

To solve this problem, we use the formula:

z = (x – u) / s

where z is the z score value which can be obtained from the tables, x is the sample value, u is the mean = 6.3 min, and s is the std dev = 2.2 min

 

at P value = 0.90, the z = 1.28, finding for x:

x = z s + u

x = 1.28 * 2.2 + 6.3

x = 9.116

 

at P value = 1.0, the z = 3.49, finding for x:

x = z s + u

x = 3.49 * 2.2 + 6.3

x = 13.978 ~ 14

 

Therefore the longest 10% calls last about 9.1 minutes to 14 minutes
