the average weekly work hours of full-time u.s. workers have approximately a normal distribution with mean 37 hours and standard deviation hours. suppose 200 u.s. citizens are randomly chosen. find an approximate probability that less than 10 of them are working more than 50 hours a week on average (round off to third decimal place).
The approximate probability that less than 10 out of 200 U.S. citizens are working more than 50 hours a week on average is 0.019
We can use the normal distribution to approximate the probability that less than 10 out of 200 U.S. citizens are working more than 50 hours a week on average.
To do this, we have to standardize the variable by subtracting the mean and dividing by the standard deviation.
In this case, X = (50 - 37) / hours = 1.83
We know that for a standard normal distribution, the probability of X being less than a certain value can be found using a standard normal table or a calculator with a built-in standard normal cumulative distribution function (CDF).
Now, we will use the cumulative distribution function to find the probability of less than 10 out of 200 working more than 50 hours a week on average. Using a standard normal table or calculator, we can find the probability of having X < -2.04.
P(X < -2.04) = 0.0188
So the approximate probability that less than 10 out of 200 U.S. citizens are working more than 50 hours a week on average is 0.0188 which rounding it off to the third decimal place we get 0.019.

C. 7
D. 3
Answer:
A
Step-by-step explanation:
A
The number of sides for a regular polygon that will not form a regular tessellation is 7. The correct option is C.
What is a polygon?A polygon is a planar figure characterised by a limited number of straight-line segments joined to create a closed polygonal chain in geometry. A polygon is defined as a bounded planar region, a bounding circuit, or both.
A tessellation or tiling is the seamless covering of a surface, frequently a plane, with one or more geometric shapes, known as tiles. One regular polygon can be used to create a single regular tessellation. Two or more regular polygons are used in a semi-regular tessellation.
Triangles, squares, and hexagons are the only three regular tessellations.
Now, the name of the polygon having 3, 4, and 6 sides is triangle, square, and Hexagon. Therefore, the only regular polygon that will not form a regular tessellation is heptagon, which has 7 sides.
Hence, the number of sides for a regular polygon that will not form a regular tessellation is 7.

We need Pigeonhole Principle which states,
The pigeonhole principle is one of the simplest but most useful ideas in mathematics, and can rescue us here. A basic version says that if (N+1) pigeons occupy N holes, then some hole must have at least 2 pigeons. Thus if 5 pigeons occupy 4 holes, then there must be some hole with at least 2 pigeons.
We know that there are 40 odd integers 1, 3, 5, 7, ....79 and 41 even integers 0, 2, 4, 6, .....80 from 0 to 80 .
So, at most, 41 integers picked out of them. If we pick one more integer after picking all of these then it must be odd integer according to Pigeonhole Principle. Therefore, we need to at least one more integer from 0 through 80 to be sure that there is at least one odd integer.
So, in total we need to pick at least 41 + 1 = 42 integers from 0 to 80 to be sure of getting at least one that is odd.

3/7 of a number is 24. Find the number.
determine whether the relation defines y as a function of x. Guve the domain.
Answer
Explanation
Given:
\(y=-\frac{5}{x}\)To determine whether the relation defines y as a function of x, we get the domain first.
Based on the given relation, when we plug in x=0, the value would be undefined. So the function domain is x<0 or x>0.
Hence, the interval notation is:
\((-\infty,0)\cup(0,-\infty)\)We can use vertical line test to determine if it is a function as shown in the graph below:
As we can see, there's only one point of intersection so the relation defines y as a function of x. Therefore, the answer is:
Function; domain
\((-\infty,0)\cup(0,-\infty)\)The function:
V(x) = x(10-2x)(16-2x), 0
a) Find the extreme values of V.
b) Interpret any valuse found in part (a) in terms of volumeof the box.
The minimum value of V occurs at x ≈ 0.93, which means that the volume of the box is smallest when the height is about 0.93 units.
To find the extreme values of V, we need to take the derivative of V and set it equal to zero. So, let's begin:
\(V(x) = x(10-2x)(16-2x)\)
Taking the derivative with respect to x:
\(V'(x) = 10x - 4x^2 - 32x + 12x^2 + 320 - 48x\)
Setting V'(x) = 0 and solving for x:
\(10x - 4x^2 - 32x + 12x^2 + 320 - 48x = 0\\8x^2 - 30x + 320 = 0\)
Solving for x using the quadratic formula:
\(x = (30 ± \sqrt{(30^2 - 4(8)(320))) / (2(8))\\x = (30 ± \sqrt{(1680)) / 16\\x = 0.93 or x =5.07\)
So, the extreme values of V occur at x ≈ 0.93 and x ≈ 5.07. To determine whether these are maximum or minimum values, we need to examine the second derivative of V. If the second derivative is positive, then the function has a minimum at that point. If the second derivative is negative, then the function has a maximum at that point. If the second derivative is zero, then we need to use a different method to determine whether it's a maximum or minimum.
Taking the second derivative of V:
V''(x) = 10 - 8x - 24x + 24x + 96
V''(x) = -8x + 106
Plugging in x = 0.93 and x = 5.07:
V''(0.93) ≈ 98.36 > 0, so V has a minimum at x ≈ 0.93.
V''(5.07) ≈ -56.56 < 0, so V has a maximum at x ≈ 5.07.
Now, to interpret these values in terms of the volume of the box, we need to remember that V(x) represents the volume of a box with length 2x, width 2x, and height x. So, the maximum value of V occurs at x ≈ 5.07, which means that the volume of the box is greatest when the height is about 5.07 units. The minimum value of V occurs at x ≈ 0.93, which means that the volume of the box is smallest when the height is about 0.93 units.

a) The extreme values of V are:
Minimum value: V(0) = 0
Relative maximum value: V(3) = 216
Absolute maximum value: V(4) = 128
b) The absolute maximum value of V at x = 4 represents the case where the box has a square base of side length 4 units, height 2 units, and width 8 units, which has a volume of 128 cubic units.
a) To find the extreme values of V, we first need to find the critical points of the function. This means we need to find where the derivative of the function equals zero or is undefined.
Taking the derivative of V(x), we get:
\(V'(x) = 48x - 36x^2 - 4x^3\)
Setting this equal to zero and solving for x, we get:
\(48x - 36x^2 - 4x^3 = 0\)
4x(4-x)(3-x) = 0
So the critical points are x = 0, x = 4, and x = 3.
We now need to test these critical points to see which ones correspond to maximum or minimum values of V.
We can use the second derivative test to do this. Taking the derivative of V'(x), we get:
\(V''(x) = 48 - 72x - 12x^2\)
Plugging in the critical points, we get:
V''(0) = 48 > 0 (so x = 0 corresponds to a minimum value of V)
V''(4) = -48 < 0 (so x = 4 corresponds to a maximum value of V)
V''(3) = 0 (so we need to do further testing to see what this critical point corresponds to)
To test the critical point x = 3, we can simply plug it into V(x) and compare it to the values at x = 0 and x = 4:
V(0) = 0
V(3) = 216
V(4) = 128
So x = 3 corresponds to a relative maximum value of V.
b) In terms of the volume of the box, the function V(x) represents the volume of a rectangular box with a square base of side length x and height (10-2x) and width (16-2x).
The minimum value of V at x = 0 represents the case where the box has no dimensions (i.e. it's a point), so the volume is zero.
The relative maximum value of V at x = 3 represents the case where the box is a cube with side length 3 units, which has a volume of 216 cubic units.
