Calculate the p-value for the following conditions and determine whether or not to reject the null hypothesis:
a) one-tail test, Zx= 1.46, and a = 0.10
b) one-tail test, Zx = -2.48, and a = 0.01
c) two-tail test, Zx= -1.92, and a = 0.01
d) two-tail test, Zx = 2.76, and a = 0.02
Answers
(a) As the P-value is less than a = 0.10. So, we reject the null hypothesis.
(b) As the P-value is less than a = 0.01. So, we reject the null hypothesis.
(c) As the P-value is less than a = 0.01. So, we reject the null hypothesis.
(d) As the P-value is less than a = 0.02. So, we reject the null hypothesis.
What is the null hypothesis?
The null hypothesis asserts that no relationship exists between two sets of data or variables under consideration. The null hypothesis states that any empirically observed difference is due solely to chance and that no underlying causal relationship exists, hence the term "null."
Here, we have
(a) one-tail test, Zx= 1.46, and a = 0.10
We have to find the P-value for the following conditions and determine whether or not to reject the null hypothesis.
The P-value for the right-tailed test is defined as
P(Zx > 1.46) = 1 - P(Zx ≤ 1.46)
= 1 - 0.9276
= 0.0721
As the P-value is less than a = 0.10. So, we reject the null hypothesis.
(b) one-tail test, Zx = -2.48, and a = 0.01
We have to find the P-value for the following conditions and determine whether or not to reject the null hypothesis.
The P-value for the right-tailed test is defined as
P(Zx < -2.48) = 0.0066
As the P-value is less than a = 0.01. So, we reject the null hypothesis.
(c) two-tail test, Zx= -1.92, and a = 0.01
We have to find the P-value for the following conditions and determine whether or not to reject the null hypothesis.
The P-value for the right-tailed test is defined as
P(|Zx| > -1.92) = 2×P(Zx≤ -1.92)
= 2×0.0274
= 0.0549
As the P-value is greater than a = 0.01. So, we reject the null hypothesis.
(d) two-tail test, Zx = 2.76, and a = 0.02
We have to find the P-value for the following conditions and determine whether or not to reject the null hypothesis.
The P-value for the right-tailed test is defined as
P(|Zx| > 2.76) =2×P(Zx≤ -2.76)
= 2×0.0029
= 0.0058
As the P-value is less than a = 0.02. So, we reject the null hypothesis.

let a ∈ rn×n be a symmetric nonsingular positive semi-definite matrix, b ∈ rn, and c ∈r. show that ∫ x∈rn exp{−1 2 xt ax −xt b −c}dx
Answers
The integral is to zero for a symmetric nonsingular positive semi-definite matrix A, and the expression is
∫ x∈\(R^n\) exp\((-1/2 x^T A x - x^T b - c) dx\) = 0.
The integral ∫ x∈R^n exp(-1/2 x^T A x - x^T b - c) dx, where A is a symmetric nonsingular positive semi-definite matrix, b ∈ R^n, and c ∈ R, can be evaluated.
To evaluate this integral, we can make use of the Gaussian integral formula for multi-dimensional integrals. The formula states that:
∫ exp\((-1/2 x^T C x) dx = ((2π)^(n/2)) / sqrt(det(C)),\)
where C is a positive definite matrix.
In our case, A is a symmetric positive semi-definite matrix. Since A is positive semi-definite, we can write it as A = Q^T D Q, where Q is an orthogonal matrix and D is a diagonal matrix with non-negative eigenvalues. As A is symmetric and positive semi-definite, its eigenvalues are non-negative.
Now, we can rewrite the integral as:
∫ exp\((-1/2 x^T A x - x^T b - c) dx = exp(-c) ∫ exp(-1/2 x^T A x - x^T b) dx.\)
Let's complete the square inside the exponent to further simplify the integral. We can rewrite the exponent as:
\(-1/2 x^T A x - x^T b = -1/2 (x^T A x + 2 x^T (A^-1 b)),\)
where A^-1 is the inverse of A.
Now, let's substitute y = x + A^-1 b. We have dy = dx, and the integral becomes:
exp(-c) ∫ exp(-1/2 y^T A y) dy.
At this point, we can apply the Gaussian integral formula mentioned earlier, with C = A. Therefore, the integral becomes:
exp(-c) ((2π)^(n/2)) / sqrt(det(A)).
Since A is positive semi-definite, its determinant is non-negative. So, we have sqrt(det(A)) = sqrt(0) = 0 for a positive semi-definite matrix A.
Therefore, the integral evaluates to zero for a symmetric nonsingular positive semi-definite matrix A, and the expression becomes:
∫ x∈R^n exp(-1/2 x^T A x - x^T b - c) dx = 0.
Thus, the integral is equal to zero.

To solve for x, you need to isolate the variable to one side of the equation. To do that, you need to use reverse operations. For example, the reverse operation of subtraction is addition.
In this case, we have:
15 = 5x
5x is the same thing as 5 (x) or 5 times x. This means the reverse operation is division. So, we need to divide both sides of the equation by 5:

Faizah is paid $11 per hour for her work at a factory. She works 9 hours a day and 24 days a month. She saves $594 a month. Express the amount she saves as a percentage of her income.
Answers
Answer:
The amount she saves is 25% of her income
Step-by-step explanation:
She is paid $11 per hour
She works 9 hours per day
and for 24 days per month
So, she works 9(24) hours per month
= 216 hours per month
Now, she is paid $11 hourly, so for 216 hours,
she will have 11(216) = $2376
Total income = $2376 per month
Saving = $594 per month
As a percentage, we divide the savings by the total income,
savings/(total income) = 594/2376 = 1/4 = 0.25
Hence we get 25%

Write an equation for each boat rental company that gives the cost in dollars y of renting a kayak for x hours. What is the difference in cost between the company that charges the most and the one that charges the least for 4 hours?
A table titled Company A with two columns and five rows is shown. The first column is the number of hours. The second column is the total cost in dollars. For two hours, the cost is thirty-three dollars. For three hours, the cost is forty-nine dollars and fifty cents. For four hours, the cost is sixty-six dollars. For five hours, the cost is eighty-two dollars and fifty cents.
Company B The cost y of renting a kayak for x hours is $9.00 for each half hour.
Company C The cost y of renting a kayak is $14.25 per hour.
Answers
Using linear functions, the costs are given as follows:
A(x) = 16x + 1.B(x) = 18x.C(x) = 14.25x.For 4 hours, the difference is costs between the company that charges the most and the one that charges the least is of $15.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For Company A, we have two points on the column: (2, 33), (3, 49). Hence for one additional hour, the cost increased by $16, hence the slope is of 16 and:
A(x) = 16x + b.
When x = 2, A(x) = 33, hence we use it to find b as follows:
33 = 16(2) + b
b = 1.
Hence:
A(x) = 16x + 1.
Companies B and C have intercepts of 0, while the slopes are hourly costs, hence:
B(x) = 18x -> 9 for each half hour = 18 for an hour.C(x) = 14.25x.For 4 hours, the costs are given as follows:
A(4) = 16(4) + 1 = 65.B(4) = 18(4) = 72.C(4) = 14.25(4) = 57.The difference is:
72 - 57 = 15.
For 4 hours, the difference is costs between the company that charges the most and the one that charges the least is of $15.

Part C: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part A and Part B to draw the graph. (5 points)
Answers
a) The x-intercepts of the graph of f(x) are x = 2.5 and x = -1.
b) The coordinates of the vertex are (0.75, -5.125).
c) By using the x-intercepts and vertex obtained in Parts A and B, we can accurately depict the shape and positioning of the parabolic graph of f(x).
Part A: To find the x-intercepts of the graph of f(x), we set f(x) equal to zero and solve for x.
Setting f(x) = 0:
\(2x^2 - 3x - 5 = 0\)
To solve this quadratic equation, we can either factor it or use the quadratic formula. In this case, factoring is not straightforward, so let's use the quadratic formula:
x = (-b ± √(b^2 - 4ac)) / (2a)
For our equation, a = 2, b = -3, and c = -5. Substituting these values into the quadratic formula:
x = (-(-3) ± √((-3)^2 - 4(2)(-5))) / (2(2))
x = (3 ± √(9 + 40)) / 4
x = (3 ± √49) / 4
x = (3 ± 7) / 4
This gives us two possible solutions:
x1 = (3 + 7) / 4 = 10/4 = 2.5
x2 = (3 - 7) / 4 = -4/4 = -1
Therefore, the x-intercepts of the graph of f(x) are x = 2.5 and x = -1.
Part B: To determine whether the vertex of the graph of f(x) is a maximum or minimum, we need to consider the coefficient of the x^2 term in the function f(x). In this case, the coefficient is positive (2), which means the parabola opens upward and the vertex represents a minimum point.
To find the coordinates of the vertex, we can use the formula x = -b / (2a). In our equation, a = 2 and b = -3:
x = -(-3) / (2(2))
x = 3 / 4
x = 0.75
To find the corresponding y-coordinate, we substitute x = 0.75 into the function f(x):
f(0.75) = 2(0.75)^2 - 3(0.75) - 5
f(0.75) = 2(0.5625) - 2.25 - 5
f(0.75) = 1.125 - 2.25 - 5
f(0.75) = -5.125
Therefore, the coordinates of the vertex are (0.75, -5.125).
Part C: To graph the function f(x), we can follow these steps:
Plot the x-intercepts obtained in Part A: (2.5, 0) and (-1, 0).
Plot the vertex obtained in Part B: (0.75, -5.125).
Determine if the parabola opens upward (as determined in Part B) and draw a smooth curve passing through the points.
Extend the curve to the left and right of the vertex, ensuring symmetry.
Label the axes and any other relevant points or features.
By using the x-intercepts and vertex obtained in Parts A and B, we can accurately depict the shape and positioning of the parabolic graph of f(x).
The x-intercepts help determine where the graph intersects the x-axis, and the vertex helps establish the lowest point (minimum) of the parabola. The resulting graph should show a U-shaped curve opening upward with the vertex at (0.75, -5.125) and the x-intercepts at (2.5, 0) and (-1, 0).

The closest point will be the point on the plane that is closest to the origin, which is the orthogonal projection of the origin onto the plane.
First, we need to find the normal vector of the plane. The coefficients of x, y, and z in the equation of the plane give us the normal vector. So, the normal vector of the plane is (4, 2, -1).
Next, we need to find the projection of the origin onto the plane. The projection of a vector v onto a plane with normal vector n is given by the formula:
\(proj_n(v) = v - ((v . n) / ||n||^2) * n\)
where "." denotes the dot product, "||n||" denotes the magnitude of the normal vector, and "proj_n(v)" denotes the projection of v onto the plane with normal vector n.
In this case, the vector v is the origin, which is (0, 0, 0), and the normal vector is (4, 2, -1). So, we can calculate the projection of the origin onto the plane as follows:
\(proj_n(v) = (0, 0, 0) - (((0, 0, 0) . (4, 2, -1)) / ||(4, 2, -1)||^2) * (4, 2, -1)\)
= (0, 0, 0) - (0 / 21) * (4, 2, -1)
= (0, 0, 0)
Therefore, the projection of the origin onto the plane is the origin itself.
Finally, we can find the coordinates of the point on the plane that is closest to the origin by setting z = 0 in the equation of the plane:
0 = 4x + 2y + 3
Solving for y, we get:
y = (-2x - 3/2)
So, the coordinates of the point on the plane that is closest to the origin are:
x = 3/8
y = -15/8
z = 0
Therefore, the point (3/8, -15/8, 0) on the plane z = 4x + 2y + 3 is closest to the origin.
