The situation in which Shawn's activity will result in a final value of zero is Shawn travels east ten feet and then travels south ten feet. The correct option is D.

This is because when Shawn travels east ten feet, he moves horizontally to the right of his starting point. When he travels south ten feet after that, he moves vertically downwards from his previous position, cancelling out the horizontal movement he made earlier.

The displacement caused by Shawn's movement in the east direction is equal in magnitude but opposite in direction to the displacement caused by his movement in the south direction.

The net displacement of Shawn's movement is zero, and he ends up back at his starting point. Options A, B, and C do not involve any movements that result in a net displacement of zero.

The vertices of the triangle after reflection over y=x are (-1, 5), (-4, 1) and (-1, 0).

The vertices of the triangle from the given graph are (-5, -1), (-1, -4) and (0, -1).

Reflection across line y=x.

Reflect over the y = x, when you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed).

After reflection over y=x, we get vertices has

(-5, -1)→(-1, 5)

(-1, -4)→(-4, 1)

(0, -1)→(-1, 0)

Therefore, the vertices of the triangle after reflection over y=x are (-1, 5), (-4, 1) and (-1, 0).

We have: P(brown then yellow) = 2/11 and P(green then green) = 2/132.

What is probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen.

let's calculate the probability of selecting a brown marble followed by a yellow marble without replacement:

P(brown then yellow) = (4/12) * (6/11) = 24/132 = 2/11

We multiply 4/12 (the probability of selecting a brown marble on the first draw) by 6/11 (the probability of selecting a yellow marble on the second draw, after one brown marble has already been removed). Note that we divide by 11 on the second draw, as there are now only 11 marbles left in the bag.

Now let's calculate the probability of selecting two green marbles without replacement:

P(green then green) = (2/12) * (1/11) = 2/132

We multiply 2/12 (the probability of selecting a green marble on the first draw) by 1/11 (the probability of selecting another green marble on the second draw, after one green marble has already been removed). Again, note that we divide by 11 on the second draw, as there are now only 11 marbles left in the bag.

So, we have:

P(brown then yellow) = 2/11

P(green then green) = 2/132

The test is two-tailed because we are testing for a change in either direction. we reject the null hypothesis and support the College's claim that the algebra ability of their students has changed

(a)The hypothesis for this test can be stated as follows:

H0: The average number of equations that students can solve per day is still 10. (μ = 10)

H1: The average number of equations that students can solve per day has changed. (μ ≠ 10)

The alternative hypothesis (H1) suggests that there has been a change in the algebra ability of the students. The test is two-tailed because we are testing for a change in either direction.

(b) A t-test should be used in this case because the population standard deviation is unknown, and the sample size is relatively small (n = 113). The t-test is appropriate when the population standard deviation is unknown and when the sample size is small.

(c) To compute the test statistic, we can use the formula for the t-test:

t = (x(bar) - μ) / (s / √n)

where x(bar) is the sample mean, μ is the hypothesized population mean, s is the sample standard deviation, and n is the sample size.

Given: x(bar) = 13 μ = 10 s = 1.5 n = 113

Substituting the values into the formula, we have:

t = (13 - 10) / (1.5 / √113)

t = 2.186

(d) The critical value for a two-tailed test at a significance level of 99% can be obtained from the t-distribution table or using software. The critical value will depend on the degrees of freedom, which is n - 1 = 113 - 1 = 112.

Assuming the critical value to be tα/2,112,

(e)we can determine whether the calculated test statistic falls in the region of rejection or not. If it falls in the region of rejection, we reject the null hypothesis and support the College's claim that the algebra ability of their students has changed. If it does not fall in the region of rejection, we fail to reject the null hypothesis, indicating that there is not enough evidence to support the claim of a change in algebra ability.

The line integral ∫[C] (Pdx + Qdy) over the given curve C consisting of the arc of the parabola y = x² from (0,0) to (1, 1), and the line segment from (1,1) to (0,1) is equal to 2/5.

What is integral?

The value obtained after integrating or adding the terms of a function that is divided into an infinite number of terms is generally referred to as an integral value.

To evaluate the line integral using Green's theorem, we need to find a vector field F = (P, Q) such that ∇ × F = Qₓ - Pᵧ, where Qₓ represents the partial derivative of Q with respect to x, and Pᵧ represents the partial derivative of P with respect to y.

Let's consider F = (P, Q) = (x²y², xy).

Now, let's calculate the partial derivatives:

Qₓ = ∂Q/∂x = ∂(xy)/∂x = y

Pᵧ = ∂P/∂y = ∂(x²y²)/∂y = 2x²y

The curl of F is given by ∇ × F = Qₓ - Pᵧ = y - 2x²y = (1 - 2x²)y.

Now, let's find the line integral using Green's theorem:

∫[C] (Pdx + Qdy) = ∫∫[R] (1 - 2x²)y dA,

where [R] represents the region enclosed by the curve C.

To evaluate the line integral, we need to parameterize the curve C.

The arc of the parabola y = x² from (0, 0) to (1, 1) can be parameterized as r(t) = (t, t²) for t ∈ [0, 1].

The line segment from (1, 1) to (0, 1) can be parameterized as r(t) = (1 - t, 1) for t ∈ [0, 1].

Using these parameterizations, the region R is bounded by the curves r(t) = (t, t²) and r(t) = (1 - t, 1).

Now, let's calculate the line integral:

∫∫[R] (1 - 2x²)y dA = ∫[0,1] ∫[t²,1] (1 - 2t²)y dy dx + ∫[0,1] ∫[0,t²] (1 - 2t²)y dy dx.

Integrating with respect to y first:

∫[0,1] [(1 - 2t²)(1 - t²) - (1 - 2t²)t²] dt.

Simplifying:

∫[0,1] [1 - 3t² + 2t⁴] dt.

Integrating with respect to t:

[t - t³ + (2/5)t⁵]_[0,1] = 1 - 1 + (2/5) = 2/5.

Therefore, the line integral ∫[C] (Pdx + Qdy) over the given curve C consisting of the arc of the parabola y = x² from (0,0) to (1,1), and the line segment from (1,1) to (0,1) is equal to 2/5.

The statement |A + Bi| = |A - Bi| holds true for complex numbers A and B. Geometrically, it means that A + Bi and A - Bi have equal distances from the origin.



To prove that |A + Bi| = |A - Bi|, where A and B are real numbers, we start by considering the absolute value of a complex number:|z| = √(Re(z)^2 + Im(z)^2),where Re(z) represents the real part of z and Im(z) represents the imaginary part of z.Now, let's consider A + Bi and A - Bi:|A + Bi| = √(A^2 + B^2),|A - Bi| = √(A^2 + (-B)^2) = √(A^2 + B^2).

Since both expressions yield the same result, we conclude that |A + Bi| = |A - Bi|.Geometrically, this result means that the magnitudes of two complex numbers with the same real part and opposite imaginary parts are equal. In the complex plane, A + Bi and A - Bi are reflections of each other across the real axis. Therefore, their distances from the origin (their magnitudes) are the same.



Therefore, The statement |A + Bi| = |A - Bi| holds true for complex numbers A and B. Geometrically, it means that A + Bi and A - Bi have equal distances from the origin.
