Answer:
Step-by-step explanation:
Given
Solving (a): The cost function:
From the given parameter, it shows that the number of floor has no effect on the floors.
So, represent the floors with x.
The cost function is:
Solving (b): The slope and its interpretation
A function is represented as:
Where:
By comparing: to
So:
<em>What it means is that, no matter the number of floors, the cost remains unchanged.</em>
Answer:
19, because it wouldn't be close to becoming a whole.

Answer:
0.4996
Step-by-step explanation:
We are given;
Population proportion; p = 14% = 0.14
Sample size; n = 804
Sample proportion; p^ = 13% = 0.13
Standard deviation; σ = √np(1 - p)
σ = √(804 × 0.14 × (1 - 0.14))
σ = 9.8388
Formula for z-score is;
z = (p^ - p)/σ
z = (0.13 - 0.14)/9.8388
z = -0.01/9.8388
z = -0.001
From online z-score and probability converter attached, we have;
P(Z < -0.001) = 0.4996
$431.85. I got this by multiplying the amount of weeks in a year (52) by two to get 104. I then multiplied that by 3.5 to get 364. I then added 32.85 and 35 to that to get $431.85
