6 = 5r - 14
6 + 14 = 5r
20 = 5r
r = 4
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
Answer:
Mutiply this by whatever other value there is.
Step-by-step explanation:
F(-5)= 3-2(-5)
= 3+10
= 13
Hope it helps :))
the initial statement is:
and then:
So the second statement is false because f should be multiply by e, not by d so is option C)
