You intend to estimate a population mean with a confidence interval. You believe the population to have a normal distribution. Your sample size is 7.
While it is an uncommon confidence level, find the critical value that corresponds to a confidence level of 95.9%.
(Report answer accurate to three decimal places with appropriate rounding.)
ta/2 = ±
The critical value that corresponds to a confidence interval of 95.9% is 1.99.
The distribution of the sample mean will be roughly normally distributed, according to the Central Limit Theorem, if we have an unknown population with a mean and standard deviation and adequately small random samples (n < 30) are chosen from the population with replacement.
Then, the mean of the sample means is given by,
μ(x) = μ
And the standard deviation of the sample means is given by,
σ = σ / [tex]\sqrt{n}[/tex]
In this case the sample selected is of size, n = 7.
As the sample size n = 7 < 30, the sampling distribution of sample mean will be approximately normal.
So, a z-interval will be used to estimate the population mean.
The confidence level is, 95.9%.
The value of α is:
∝ = 1 - confidence level
∝ = 1 - 0.959
∝ = 0.041
The critical value is:

The solution to the given inequality is x ≤ -18 which is the correct answer that would be an option (D).
The inequality is given in the question as:
3 -x/2 ≥ 12
To solve this inequality, we need to isolate the variable x. To do this, we can start by subtracting 12 from both sides of the inequality:
3 - x/2 ≥ 12
3 - x/2 - 12 ≤ 0
Next, we can simplify the left side of the inequality by combining like terms:
-x/2 - 9 ≤ 0
Finally, we can solve for x by adding 9 to both sides and multiplying both sides by -2:
x ≤ -18
Thus, the solution to the inequality is x ≤ -18.

Since the function f(x) = 9.25x + 3 represents the amount of money that Radda earns dog walking for x hours, Radda's earnings would increase by $12.25 each hour.
How to write a linear function for the total amount of money Radda earns?In Mathematics, a linear function is sometimes referred to as an expression or the slope-intercept form of a straight line and it can be used to model (represent) the total amount of money that is being earned by Radda for dog walking;
T = mx + b
Where:
T represents the total amount of money earned.m represents the rate of change (slope) per hour.x represents the number of hours or time.b represents the y-intercept or initial amount.Therefore, the required linear function that represents the total amount of money that is being earned by Radda for dog walking per hour is given by this mathematical expression;
f(x) = T = 9.25x + 3
When the number of hours Radda spend dog walking is equal to 1 (x = 1), the rate of change(slope) can be calculated as follows;
f(1) = T = 9.25(1) + 3
f(1) = T = 9.25 + 3
f(1) = T = $12.25.
In this context, we can reasonably infer and logically conclude that Radda's earnings increases each hour by $12.25.

The function below has at least one rational zero. Use this fact to find all zeros of the function. f(x)=7x^4 +27x^3 -40x^2 +x +5
The rational zeros of the function can be found using the Rational Zero Theorem. The possible rational zeros of the function are ±1, ±5, ±1/7, ±5/7.
Zeros:
x=-5, -1/7, 0, 1, 5
The Rational Zero Theorem states that if a polynomial function of degree n has integer coefficients, then the possible rational zeros of the function will be of the form ±p/q, where q is a factor of the leading coefficient and p is a factor of the constant term.
In this case, the degree of the polynomial is 4, which means that the leading coefficient is 7 and the constant term is 5. Thus, the possible rational zeros of the function will be of the form ±p/q, where p is a factor of 5 and q is a factor of 7. The factors of 5 are ±1 and ±5, and the factors of 7 are ±1 and ±7. This means that the possible rational zeros of the function are ±1, ±5, ±1/7, and ±5/7.
To find the zeros of the function, we can use the rational zeros we found and plug them into the original equation. We can then solve for the zeros and find that the zeros of the function are x=-5, -1/7, 0, 1, 5.
x=-5: 7(-5)^4 +27(-5)^3 -40(-5)^2 +(-5) +5= 0

a 9 foot ladder is leaning against a wall. if the top of the ladder is sliding down the wall at a rate of
The rate at which the top of ladder slide down is 8.48 ft/s. The negative sign implies that the height is reducing with time which is true because it is sliding down.
The well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, [tex]a^{2}+b^{2} =c^{2}[/tex]
Given that,
Length of the ladder is, [tex]l=9ft[/tex]
Let the top of ladder be at height of 'h' and the bottom of the ladder be at a distance of 'b' from the wall.
Now, from triangle ABC,
[tex]AB^{2} +BC^{2} =AC^{2}[/tex]
[tex]h^{2} +b^{2} =l^{2}[/tex]
[tex]h^{2} +b^{2}[/tex] = [tex]9^{2}[/tex]
[tex]h^{2} +b^{2}[/tex] = 81 (Equation-1)
Differentiating the above equation with respect to time, 't'.
So,
We can write,
[tex]\frac{d}{dt} (h^{2}+b^{2} )[/tex] = [tex]\frac{d}{dt}[/tex] (81)
[tex]\frac{d}{dt} (h^{2}+b^{2} )[/tex] = 0
[tex]2h\frac{dh}{dt} +2b\frac{db}{dt}[/tex] = 0
[tex]h\frac{dh}{dt} +b\frac{db}{dt}[/tex] = 0 (Equation-2)
In the above equation the term [tex]\frac{dh}{dt}[/tex] is the rate at which top of ladder slides down and [tex]\frac{db}{dt}[/tex] is the rate at which bottom of ladder slides away.
Let us assume,
h = 3 ft and db/dt = 3 ft/s
We can substitute values in equation-1,
[tex]3^{2} +b^{2}[/tex] = 81
9 + [tex]b^{2}[/tex] = 81
[tex]b^{2}[/tex] = 81-9
[tex]b^{2}[/tex] = 72
b = [tex]\sqrt{72}[/tex]
b = 8.48 ft
Now, plug in all the given values in equation (2) and solve for [tex]\frac{dh}{dt}[/tex]
3*[tex]\frac{dh}{dt}[/tex] + 8.48 * 3 = 0
3*[tex]\frac{dh}{dt}[/tex] + 25.44 = 0
3*[tex]\frac{dh}{dt}[/tex] = - 25.44
[tex]\frac{dh}{dt}[/tex] = -25.44/3
[tex]\frac{dh}{dt}[/tex] = - 8.48 ft/s
Therefore,
The rate at which the top of ladder slide down is 8.48 ft/s. The negative sign implies that the height is reducing with time which is true because it is sliding down.

Does the given matrix, A, have an inverse? If it does, what is A^-1?
The inverse of the matrix A is (b) [tex]A^{-1} = \left[\begin{array}{cc}7&25\\-2&-7\end{array}\right][/tex]
How to determine the inverse of the matrix?From the question, we have the following parameters that can be used in our computation:
[tex]A = \left[\begin{array}{cc}-7&-25\\2&7\end{array}\right][/tex]
To calculate the inverse of the matrix, we start by calculating the determinant of the matrix
This is calculated as follows
|A| = -7 * 7 + 25 * 2
Evaluate the products in the above equation
So, we have the following representation
|A| = -49 + 50
Evaluate the sum in the above equation
So, we have the following representation
|A| = 1
The inverse is then calculated as
[tex]A^{-1} = \frac{1}{|A|} * \left[\begin{array}{cc}7&25\\-2&-7\end{array}\right][/tex]
Substitute the known values in the above equation, so, we have the following representation
[tex]A^{-1} = \frac{1}{1} * \left[\begin{array}{cc}7&25\\-2&-7\end{array}\right][/tex]
Evaluate the quotient
[tex]A^{-1} = 1 * \left[\begin{array}{cc}7&25\\-2&-7\end{array}\right][/tex]
This gives
[tex]A^{-1} = \left[\begin{array}{cc}7&25\\-2&-7\end{array}\right][/tex]
Hence, the inverse is (b)

III.(4,-2)
IV. (1, 2)
The solutions to the given Inequalities are Option II. (0, -2) and Option IV. (1, 2).
What are inequalities:In mathematics, inequalities describe the connection between two non-equal numbers. Equal does not imply inequality.
Various types of inequalities are used to compare the values and determine whether they are smaller than or greater than.
It indicates that the phrase on the left should be either larger or smaller than that of the expression on the right, or vice versa.
Here we have
2y ≥ -4x + 4 --- (1)
x - 2 > 2y ---- (2)
Substitute each given point and find for which both equations will be satisfied
For Option I. (-2, 1)
(1) => 2(1) ≥ -4(-2) + 4
=> 2 ≥ - 4 [ Which is true ]
(2) => -2 - 2 > 2(1)
=> - 4 > 2 [ which is not true ]
For Option II. (0, -2)
(1) => 2(-2) ≥ -4(0) + 4
=> -4 ≥ 4 [ Which is true ]
(2) => 0 - 2 > 2(-2)
=> - 2 > - 4 [ which is true ]
For option III. (4,-2)
(1) => 2(-2) ≥ -4(4) + 4
=> - 4 ≥ - 12 [ Which is true ]
(2) => 4 - 2 > 2(1)
=> 2 > 2 [ which is not true ]
