Answer:
33.5+127=160.5
180-160.5=19.5
Step-by-step explanation:
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: Choice C) ![-\infty < y < 2](https://tex.z-dn.net/?f=-%5Cinfty%20%3C%20y%20%3C%202)
</h3>
This is a more complicated way to write ![y < 2](https://tex.z-dn.net/?f=y%20%3C%202)
The range is the set of all possible y outputs of a function. So we use the graph to see what y values are possible. The graph shows that y can be anything smaller than y = 2. We can't actually reach y = 2 itself due to a horizontal asymptote here.
In interval notation, the answer would be
with the curved parenthesis to indicate "do not include y = 2 as part of the range".
