Answer:
(-∞, 5 U 7 , ∞)
Step-by-step explanation:
Given the inequality expressions
d – 4 > 3 or d – 4 < 1
For d - 4 > 3
Add 4 to both sides
d-4 + 4 > 3 + 4
d > 7
7 < d
this means that d is greater than 7,
(7 , ∞)
For d - 4 < 1
Add 4 to both sides
d - 4 + 4 < 1 + 4
d < 5
This means d is less than 5
(-∞, 5)
The required solution is (-∞, 5 U 7 , ∞)
Your answer would be 32.

The probability of selecting a 55 one-bedroom apartment is 1 and the value of z is 38.53.
Given,
Mean of rent of one bedroom apartment = $2075
The standard deviation of rent of the apartment = $300
n = 55
x' = $1985
We have to find x' to be at least $1985 which is P(x' > $1985).
The z-value is calculated from,
z = (x' - u)/√std. deviation/n
Putting the values, we get;
z = (1985 - 2075)/(√300/55)
or, z = -38.536
So, P(x' > $1985)
or, P(z > -38.5364)
This changes to:
P(z < 38.5364)
Hence the probability from the z distribution table is 1 and the value of z is 38.5364.
