A 90% confidence interval estimate of the standard deviation of body temperature of all healthy humans is done below:
Given:
Sample size(n) = 100
Sample mean(x) = 98.40°
Sample standard deviation(s) = 0.61°F
Level of Confidence(C) = 90% (α = 0.10)
Degrees of Freedom(df) = n - 1 = 100 - 1 = 99
The formula for the confidence interval estimate of the standard deviation of the population is:((n - 1)s²)/χ²α/2,df < σ² < ((n - 1)s²)/χ²1-α/2,df
Now we substitute the given values in the formula above:((n - 1)s²)/χ²α/2,df < σ² < ((n - 1)s²)/χ²1-α/2,df((100 - 1)(0.61)²)/χ²0.05/2,99 < σ² < ((100 - 1)(0.61)²)/χ²0.95/2,99(99)(0.3721)/χ²0.025,99 < σ² < (99)(0.3721)/χ²0.975,99(36.889)/χ²0.025,99 < σ² < 36.889/χ²0.975,99
Using the table of Chi-Square critical values, the values of χ²0.025,99 and χ²0.975,99 are 71.42 and 128.42 respectively.
Finally, we substitute these values in the equation above to obtain the 90% confidence interval estimate of the standard deviation of body temperature of all healthy humans:36.889/128.42 < σ² < 36.889/71.42(0.2871) < σ² < (0.5180)Taking square roots on both sides,0.5366°F < σ < 0.7208°F
Hence, the 90% confidence interval estimate of the standard deviation of body temperature of all healthy humans is given as [0.5366°F, 0.7208°F].

Find f if f′(x)=3x2+2x+7 and f(0)=5. (b) Find f if f′′(x)=30x4−cos(x)+6,f′(0)=0 and f(0)=0.
(a) The function f(x) = \(x^{3} +x^{2}\) + 7x + 5 satisfies f'(x) = 3\(x^{2}\) + 2x + 7 and f(0) = 5. (b) The function f(x) = \(x^{6}\) + cos(x) + 3\(x^{2}\) satisfies f''(x) = 30\(x^{4}\) - cos(x) + 6, f'(0) = 0, and f(0) = 0.
To find f(x) given function f'(x) = 3\(x^{2}\) + 2x + 7 and f(0) = 5:
We integrate f'(x) to find f(x): ∫(3\(x^{2}\) + 2x + 7) dx =\(x^{3}\) + \(x^{2}\) + 7x + C
To determine the constant of integration, we substitute f(0) = 5:
0^3 + 0^2 + 7(0) + C = 5
C = 5
Therefore, f(x) = \(x^{3}\)+ \(x^{2}\) + 7x + 5.
To find f(x) given f''(x) = 30\(x^{4}\) - cos(x) + 6, f'(0) = 0, and f(0) = 0:
We integrate f''(x) to find f'(x): ∫(30\(x^{4}\) - cos(x) + 6) dx = 6\(x^{5}\) - sin(x) + 6x + C
To determine the constant of integration, we use f'(0) = 0:
6\((0)^{5}\) - sin(0) + 6(0) + C = 0
C = 0
Now we integrate f'(x) to find f(x): ∫(6x^5 - sin(x) + 6x) dx = x^6 + cos(x) + 3x^2 + D
To determine the constant of integration, we use f(0) = 0:
(0)^6 + cos(0) + 3\((0)^{2}\) + D = 0
D = 0
Therefore, f(x) =\(x^{6}\) + cos(x) + 3\(x^{2}\).

the dimensions of a square are altered so that one dimension is increased by 7 feet and the other is decreased by 2 feet. The area of the resulting rectangle is 90 sq. feet. find the original area of the square
Answer:
The original area of the square was 24
Step-by-step explanation:
Let's say the dimension of the new square is 9 and 10, that'll make 90
Let's say the original dimensions were 9 - 7, 10 + 2 which is 2, 12
The area of the original dimensions is 24 square feet and they altered that to make the resulting rectangle 90 square feet.
Answer:
The area of the original SQUARE is 64 sq feet. x = 8
It was an 8 × 8 SQUARE.
Step-by-step explanation:
Let x = the original side length.
x + 7 is a new side
x - 2 is the other new side. Its a rectangle now.
Area of a rectangle:
A = length × width
A = (x+7)(x-2)
90 = x^2 +5x -14
Solve. Subtract 90.
0 = x^2 + 5x - 104
Factor.
0 = (x + 13)(x - 8)
x + 13 = 0 and x-8=0
x = -13 and x = 8
-13 is discarded because lengths cannot be negative.
x = 8 is the original side length of the square.
Area is 8×8 = 64 sqft

Suppose that you estimate that lohi corp. will skip its next three annual dividends, but then resume paying a dividend, with the first dividend paid to be equal to $1.00. if all subsequent dividends will grow at a constant rate of 6 percent per year and the required rate of return on lohi is 14 percent per year, what should be its price? a. $6.35 b. $8.44 c. $10.37 d. $12.50 continuing the previous problem, what is lohi's expected capital gains yield over the next year? a. 10.34% b. 11.85% c. 12.08% d. 14.00%
Lohi Corp.'s expected capital gains yield over the next year is 0.48%.
To determine the price of lohi corp., we need to calculate the present value of its future dividends. First, we estimate that the company will skip the next three annual dividends. This means that we will start receiving dividends from the fourth year. The first dividend to be paid is $1.00, and subsequent dividends will grow at a constant rate of 6 percent per year. The required rate of return on lohi corp. is 14 percent per year. This is the rate of return that investors expect to earn from investing in the company.
To calculate the price of Lohi Corp., we need to use the dividend discount model (DDM). The DDM formula is:
Price = Dividend / (Required rate of return - Dividend growth rate)
In this case, we know that Lohi Corp. will skip its next three annual dividends and then resume paying a dividend of $1.00. The dividend growth rate is 6% per year, and the required rate of return is 14% per year.
First, let's calculate the present value of the future dividends:
PV = (1 / (1 + Required rate of return))^1 + (1 / (1 + Required rate of return))^2 + (1 / (1 + Required rate of return))^3
PV = (1 / (1 + 0.14))^1 + (1 / (1 + 0.14))^2 + (1 / (1 + 0.14))^3
PV = 0.877 + 0.769 + 0.675
PV = 2.321
Next, let's calculate the price:
Price = (Dividend / (Required rate of return - Dividend growth rate)) + PV
Price = (1 / (0.14 - 0.06)) + 2.321
Price = (1 / 0.08) + 2.321
Price = 12.5
Therefore, the price of Lohi Corp. should be $12.50.
To calculate the expected capital gains yield over the next year, we need to use the formula:
Capital gains yield = (Dividend growth rate) / (Price)
Capital gins yield = 0.06 / 12.5
Capital gains yield = 0.0048
Convert to percentage:
Capital gains yield = 0.0048 * 100
Capital gains yield = 0.48%
Therefore, Lohi Corp.'s expected capital gains yield over the next year is 0.48%.

6. Let u j(t)=t λ jwhere λ 1 ,…,λ n
are arbitrary unequal real numbers. Show that {u 1…u n } are linearly independent functions on anyinterval(a,b)⊂R. (Suggestion: If ∑ j=1nα j t λ j≡0, divide by t λ 1and differentiate.) 7. A side condition for a differential equation is homogeneous if whenever two functions satisfy the side condition then so does any linear combination of the two functions. For example, the Dirichlet type boundary condition u=0 for x∈∂Ω ishomogeneous. Now let Lu=∑∣α∣≤ma α(x)D α
u denote any linear differential operator. Show that the set of functions satisfying Lu=0 and any homogeneousside conditions is a vector space.
To show that the functions {u1, u2, ..., un} are linearly independent on any interval (a, b) where uj(t) = t^λj with λ1, λ2, ..., λn being arbitrary unequal real numbers, we can assume the linear combination:
α1u1(t) + α2u2(t) + ... + αnun(t) = 0,
where α1, α2, ..., αn are constants. We need to show that the only solution to this equation is α1 = α2 = ... = αn = 0.
Divide the equation by t^λ1 and differentiate both sides, we get:
α1λ1t^(λ1-1) + α2λ2t^(λ2-1) + ... + αnλnt^(λn-1) = 0.
Now, let's consider the highest power of t in the equation. Since λ1, λ2, ..., λn are unequal, there must exist a λj that is the largest among them. Let's assume it is λj. In the equation, the term αjλjt^(λj-1) is the highest power of t.
For this equation to hold for all t on the interval (a, b), the coefficient αjλj must be zero. Otherwise, the equation cannot be satisfied for t approaching zero.
Now, we have αjλj = 0, which implies αj = 0 because λj ≠ 0.
Substituting αj = 0 back into the equation, we have:
α1λ1t^(λ1-1) + α2λ2t^(λ2-1) + ... + αnλnt^(λn-1) = 0
By repeating the same argument for each term, we can conclude that all the coefficients α1, α2, ..., αn must be zero.
Therefore, the functions {u1, u2, ..., un} are linearly independent on any interval (a, b).
Regarding the second question about the set of functions satisfying Lu=0 and any homogeneous side conditions, it can indeed form a vector space. This is because the set is closed under addition and scalar multiplication, and it contains the zero function (which satisfies the homogeneous side condition). The properties of a vector space hold for this set, making it a vector space.

Find the first derivative for each of the following:
y = 3x2 + 5x + 10
y = 100200x + 7x
y = ln(9x4)
The first derivatives for the given functions are:
For \(y = 3x^2 + 5x + 10,\) the first derivative is dy/dx = 6x + 5.
For \(y = 100200x + 7x,\) the first derivative is dy/dx = 100207.
For \(y = ln(9x^4),\) the first derivative is dy/dx = 4/x.
To find the first derivative for each of the given functions, we'll use the power rule, constant rule, and chain rule as needed.
For the function\(y = 3x^2 + 5x + 10:\)
Taking the derivative term by term:
\(d/dx (3x^2) = 6x\)
d/dx (5x) = 5
d/dx (10) = 0
Therefore, the first derivative is:
dy/dx = 6x + 5
For the function y = 100200x + 7x:
Taking the derivative term by term:
d/dx (100200x) = 100200
d/dx (7x) = 7
Therefore, the first derivative is:
dy/dx = 100200 + 7 = 100207
For the function \(y = ln(9x^4):\)
Using the chain rule, the derivative of ln(u) is du/dx divided by u:
dy/dx = (1/u) \(\times\) du/dx
Let's differentiate the function using the chain rule:
\(u = 9x^4\)
\(du/dx = d/dx (9x^4) = 36x^3\)
Now, substitute the values back into the derivative formula:
\(dy/dx = (1/u) \times du/dx = (1/(9x^4)) \times (36x^3) = 36x^3 / (9x^4) = 4/x\)
Therefore, the first derivative is:
dy/dx = 4/x
To summarize:
For \(y = 3x^2 + 5x + 10,\) the first derivative is dy/dx = 6x + 5.
For y = 100200x + 7x, the first derivative is dy/dx = 100207.
For\(y = ln(9x^4),\) the first derivative is dy/dx = 4/x.

Help pls
Answer:
false
Step-by-step explanation:
AABC is isosceles.
AB = 3x - 4 and BC = 5x - 10.
AB = [?]
If AB = BC then set up the equation 3x - 4 = 5x - 10
Subtract 3x.
-4 = 2x - 10
Add 10.
6 = 2x
Divide by 2.
3 = x
AB is 3x - 4 so
3(3) - 4
9 - 4
5.
AB = 5
If AB is not equal to BC then this is not solvable.
But if they are I am sure AB = 5.
Hope this helps

∠BAE = 105°
∠AEC = 25°
We construct a line CF from C parallel to the line AE as presented in the included diagram created with Microsoft Visio
We have;
∠DCF ≅ ∠BAE = 105° by similar angles formed by two pairs of parallel lines
∠AEC = ∠ECF = 25° by alternate interior angles formed by two parallel lines and a common transversal
x = 125° + 25° = 150° By angle addition postulate
x = 150°.
Barry is 7 years older than Meisha. Which equation shows Barry’s age (b) in terms of Meisha’s age (m)?
Answer:
b-m= 7
Step-by-step explanation:
Let Barry's age is b and Meisha's age is m.
Barry is 7 years older than Meisha. Older means Barry's age is more than Meisha's age.
We can the equation as follows :
b = 7+m
or
Subtract m from both sides,
b-m= 7
Hence, the required equation is "b-m= 7".

The volume of a right circular cone is 300 cubic inches. What is the volume, in cubic inches, of
a right cylinder that has the same base and height as the cone?
Answer:
900 cubic inches.
Step-by-step explanation:
Given the following data
Volume of right circular cone = 300in³
We know that the volume of a right circular cone is given by the formula;
\( V = \frac{1}{3} \pi r^{2}h\)
Where;
V is the volume of right circular cone.r is the radius of the base of the right circular cone.h is the height of the right circular cone.The volume of a right circular cylinder is given by the formula;
\( V = \pi r^{2}h\)
Thus, multiplying the volume of the right circular cone by 3 would give us the volume of the right circular cylinder.
\( V = \frac{1}{3} \pi r^{2}h * 3\)
Substituting into the equation, we have;
V = 300 * 3
V = 900in³
Therefore, the volume of a right cylinder that has the same base and height as the cone is 900 cubic inches.
