assume that the weight loss for the first month of a diet program varies between 6 and 12 pounds
The probability of the weight loss falling between 8 pounds and 11 pounds is 1/2
Variation of weight = Between 6 to 12.
It is required to ascertain the percentage of the overall range that corresponds to that interval in order to calculate the chance that the weight reduction will fall between 8 pounds and 11 pounds.
Calculating the total range of weight -
Range = Higher weight - Lower weight
= 12 - 6
= 6
Similarly, calculating the total range of weight for 8 pounds and 11 pounds
Range = Higher weight - Lower weight
= 11 - 8
Calculating the probability -
Probability = Range of interest / Total range
= 3 / 6
= 1/2.

Find the inverse Laplace transform f(t) = --!{F(s)} of the function F(s): = 4s $2 – 81 ft= (6) - c-- {} - {22} - = 4s 81 = L وی + help (formulas) 2ی S 9 (1 point) Find the inverse Laplace transform f(t) = (-1{F(s)} of the function F(s) = = 7 52 9 + s-1' 7 f(t) = 2-1 50== -{+} = = help (formulas) S2 S - 1
(a) Inverse Laplace transform of F(s) = 4s/(s² - 81) is
[tex]f(t) = 2e^{(9t)} + 2e^{(-9t).[/tex]
We can rewrite F(s) as F(s) = 4s/[(s - 9)(s + 9)].
Using partial fraction decomposition, we can express F(s) as F(s) = A/(s - 9) + B/(s + 9), where A and B are constants.
Multiplying both sides by (s - 9)(s + 9), we get 4s = A(s + 9) + B(s - 9).
Expanding and equating coefficients, we have 4s = (A + B)s + 9A - 9B.
Equating coefficients of s on both sides, we get A + B = 4.
Equating constants on both sides, we get 9A - 9B = 0, which gives A = B.
From A + B = 4, we have 2A = 4, so A = B = 2.
Therefore, F(s) can be written as F(s) = 2/(s - 9) + 2/(s + 9).
Now, using the inverse Laplace transform formulas:
[tex]L{e^{at}} = 1/(s - a),\\L{e^{(-at)}} = 1/(s + a),[/tex]
we can find the inverse Laplace transform of F(s):
[tex]f(t) = L^{(-1)}{F(s)} = 2L^{(-1)}{1/(s - 9)} + 2L^{(-1)}{1/(s + 9)}\\= 2e^{(9t) }+ 2e^{(-9t).[/tex]
Therefore, the inverse Laplace transform of F(s) = 4s/(s² - 81) is f(t) = 2e^(9t) + 2e^(-9t).
(b) Inverse Laplace transform of F(s) = (7s + 52)/(s² + s - 1):
We can rewrite F(s) as F(s) = (7s + 52)/[(s - 1)(s + 1)].
Using partial fraction decomposition, we can express F(s) as F(s) = A/(s - 1) + B/(s + 1), where A and B are constants.
Multiplying both sides by (s - 1)(s + 1), we get (7s + 52) = A(s + 1) + B(s - 1).
Expanding and equating coefficients, we have 7s + 52 = (A + B)s + (A - B).
Equating coefficients of s on both sides, we get A + B = 7.
Equating constants on both sides, we get A - B = 52.
Solving these equations, we find A = 29 and B = -22.
Therefore, F(s) can be written as F(s) = 29/(s - 1) - 22/(s + 1).
Using the inverse Laplace transform formulas:
[tex]L{e^{at} = 1/(s - a),\\L{e^{(-at)} = 1/(s + a),[/tex]
we can find the inverse Laplace transform of F(s):
[tex]f(t) = L^{(-1)}{F(s)} = 29L^{(-1)}{1/(s - 1)} - 22L^{(-1)}{1/(s + 1)}\\= 29e^t - 22e[/tex]

Obtain the five-number summary for the given data The test scores of 15 students are listed below. 40 46 50 55 58 61 64 69 74 79 85 86 90 94 95 40,51.50, 71.5, 85.5,95 40, 55, 69, 86,95 40, 51.50, 69,
The five-number summary for the given data is as follows: Minimum = 40, First Quartile = 51.5, Median = 69, Third Quartile = 86, Maximum = 95.
To obtain the five-number summary, we consider the minimum, first quartile, median, third quartile, and maximum values of the dataset.
Minimum: The smallest value in the dataset is 40.
First Quartile: The first quartile (Q1) is the median of the lower half of the dataset. To find Q1, we arrange the data in ascending order: 40, 46, 50, 55, 58, 61, 64, 69, 74, 79, 85, 86, 90, 94, 95. Since there are 15 data points, the median is the 8th value (69), which becomes the first quartile.
Median: The median is the middle value of the dataset. In this case, since we have an odd number of data points, the median is the 8th value (69).
Third Quartile: The third quartile (Q3) is the median of the upper half of the dataset. Again, using the ordered data, we find Q3 as the median of the values above the median (69). This gives us the third quartile of 86.
Maximum: The largest value in the dataset is 95.
Thus, the five-number summary for the given data is Minimum = 40, Q1 = 51.5, Median = 69, Q3 = 86, and Maximum = 95.

Answer:

Step-by-step explanation:
explain why a divergent infinite series such as [infinity]x n=1 1 n can have a finite sum in floating-point arith- metic. at what point will the partial sums cease to change?
The partial sums will cease to change when the terms of the series become smaller than the smallest representable number in the floating-point system.
In floating-point arithmetic, there is a finite range of representable numbers and a limited precision for calculations. When dealing with infinite series, the terms are added or subtracted sequentially, but due to the limitations of numerical precision, there is a point at which the terms become too small to affect the sum significantly.
For the series 1/n, as n increases, the terms approach zero but never actually reach zero. Eventually, the terms become smaller than the smallest representable number in the floating-point system, and at this point, they essentially contribute zero to the sum. As a result, the partial sums of the series will cease to change beyond this point.
It's important to note that although the sum of the series may appear to be finite in floating-point arithmetic, mathematically, the series diverges and does not have a finite sum. The convergence to a finite value in floating-point arithmetic is a result of the limitations of numerical representation and precision. A divergent infinite series, such as the sum of 1/n from n=1 to infinity, can have a finite sum in floating-point arithmetic due to the limitations of numerical precision.

A manufacturer has cube shaped cardboard boxes with an exact volume of 12000 cubic inches. What is the volum of the largest sphere that can be packed inside the cube shaped box? Give you answer rounded to the nearest whole cubic inch
Answer:
6283 in³
Step-by-step explanation:
The largest sphere that can fit into the cardboard box must have its diameter, d equal to the length, L of the cardboard box.
Since the cardboard box is in the shape of a cube, its volume V = L³
So, L = ∛V
Since V = 12000 in³,
L = ∛(12000 in³)
L= 22.89 in
So, the volume of the sphere, V' = 4πr³/3 where r = radius of cube = L/2
So, V = 4π(L/2)³/3
= 4πL³/8 × 3
= πL³/2 × 3
= πL³/6
= πV/6
= π12000/6
= 2000π
= 6283.19 in³
≅ 6283.2 in³
= 6283 in³ to the nearest whole cubic inch
Compute the indicated quantity using the following data.
sin α = 15/17 where π/2< α < 3π/2
sin β= -4/5 where π < β < 3π/2
sin (α + β) =_________
Using trigonometric identity, sin(α + β) = -28/85.
To compute sin(α + β), we can use the trigonometric identity:
sin(α + β) = sin α cos β + cos α sin β
Given the values:
sin α = 15/17 (π/2 < α < 3π/2)
sin β = -4/5 (π < β < 3π/2)
To find sin α, we can use the Pythagorean identity:
cos α = ±√(1 - sin² α)
Since α is in the range π/2 < α < 3π/2, sin α is positive, so cos α will be negative.
sin α = 15/17
cos α = -√(1 - (15/17)²)
= -√(1 - 225/289)
= -√(64/289)
= -8/17
Now, we can substitute the values into the formula for sin(α + β):
sin(α + β) = (sin α cos β) + (cos α sin β)
= (15/17) * (-4/5) + (-8/17) * (-4/5)
= -60/85 + 32/85
= -28/85
Therefore, sin(α + β) = -28/85.
