Answer:
- f⁻¹(x) = 2x - 8
- f⁻¹(4) = 0
Step-by-step explanation:
You can find an inverse function by interchanging x and y, then solving for y.
Original function:
y = (1/2)x +4
With x and y interchanged:
x = (1/2)y +4
Subtracting 4 gives ...
x -4 = 1/2y
Multiplying by 2 gives ...
2x -8 = y
Then the inverse function is written ...
f⁻¹(x) = 2x - 8
Evaluating this for x=4, we get ...
f⁻¹(4) = 2·4 -8 = 0

Answer:
Step-by-step explanation:
Let us assume that the length of fishes in the tank is normally distributed. Thus, x is the random variable representing the length of fishes in the tank. Since the population mean and population standard deviation are known, we would apply the formula,
z = (x - µ)/(σ/√n)
Where
x = sample mean
µ = population mean
σ = standard deviation
number of samples
From the information given,
µ = 15
σ = 4
n = 31
We want to find the probability that x is between (15 - 0.5) inches and (15 + 0.5) inches. The probability is expressed as
P(14.5 ≤ x ≤ 15.5)
For x = 14.5
z = (14.5 - 15)/(4/√31) = - 0.7
Looking at the normal distribution table, the probability corresponding to the z score is 0.2420
For x = 15.5
z = (15.5 - 15)/(4/√31) = 0.7
Looking at the normal distribution table, the probability corresponding to the z score is 0.7580
Therefore,
P(14.5 ≤ x ≤ 15.5) = 0.7580 - 0.2420 = 0.5160
