Using the normal distribution, it is found that the life span of an appliance that has a z-score of –3 is of 24 months.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
In this problem, the parameters are given as follows:
.
Hence:


X - 48 = -24
X = 24.
The life span of an appliance that has a z-score of –3 is of 24 months.

Answer:
Upstream
5.2=(x-y)5
Downstream
5.2=(x+y)2.5
Step-by-step explanation:
4y + 3 > 23 subtract 3 from both sides
4y > 20 divide both sides by 4
y > 5
-2y > -2 divide both sides by -2 (the order changes)
y < 1
(-oo, 1) ∪ (5, oo)

SO SORRY IF THESE IS WRONG:(( JUST SAY IT TO ME NOT TO BULLY ME
Answer:
2 ^12
Step-by-step explanation:
16 ^3
Replace 16 with 2^4
2^4^3
We know that a^b^c = a^ (b*c)
2^(4*3)
2 ^12
