Answer:
1.04%
Step-by-step explanation:
Using the z-score formula, we have:
z = (X - P) / σ
z = score
x = given value
P = average
σ = standard deviation
Z = (40 - 43.7) / 1.6 = 2.31 > <u>0.9896</u> (tabulated in the z-table)
Now, with that number, we find the probability that a randomly selected worker works less than 40 hours per week.
1 - 0.9896 = 0.0104 * 100 = 1.04%
Answer:
A
Step-by-step explanation:
since it is <= we know that it is including the possibility of being equal so it is not a dotted line leaving only A and B as options. since its is <= it must be on the as the x increases the y must decrease. so the answer is A.

➷ 250 - 210 = 40
40 - 15.89 = 24.11
It would be option A. $24.11

<h3>Answer:</h3>
y = 2·sec((x -3π/2)/2) -4
<h3>Explanation:</h3>
The general shape of the curve suggests the parent function is a secant or cosecant function. Here, we choose to use the secant. It might help to familiarize yourself with the graph of a secant function (shown in the second attachment).
The centerline between the local maximum and local minimum is at -4, so that is the vertical offset.
The distance between that centerline and a local maximum or minimum is 2 units, so the vertical expansion factor is 2.
The horizontal distance between the local maximum and local minimum is 2π, so represents a horizontal expansion by a factor of 2.
The location of the local minimum is at x=3π/2, so that represents the horizontal offset.
The form of the function with these various transformations is ...
... g(x) = (vertical scale factor) × f((x - (horizontal offset))/(horizontal expansion factor)) - (vertical offset)
Filling in the function and the various values, we get ...
... y = 2·sec((x -3π/2)/2) -4
