How does aversive conditioning work?

An 2017 NPR/Marist poll asked a random sample of Americans if they had personally experienced sexual harassment in the workplace. The results are shown in the following table.

a. Find the percentage in each group who had personally experienced sexual harassment in the workplace.

b. Test the hypothesis that experience of sexual harassment in the workplace is associated with gender at the 0.05 significance level.

Which hydrogen in each molecule is most acidic?

$$\mathrm { a } . \mathrm { CH } _ { 3 } \mathrm { CH } _ { 2 } \mathrm { CH } _ { 2 } \mathrm { CH } _ { 2 } \mathrm { OH } \quad \mathrm { b } . \mathrm { HOCH } _ { 2 } \mathrm { CH } _ { 2 } \mathrm { CH } _ { 2 } \mathrm { NH } _ { 2 }\quad \mathrm { c } . \left( \mathrm { CH } _ { 3 } \right) _ { 2 } \mathrm { NCH } _ { 2 } \mathrm { CH } _ { 2 } \mathrm { CH } _ { 2 } \mathrm { NH } _ { 2 }$$

Find the degree over ℚ of the splitting field over ℚ of the given polynomial in ℚ[x]. (x² - 2)(x³ - 2)

For the following situations, identify the population of interest, the inferential objective, and how you might go about collecting a sample. A university researcher wants to estimate the proportion of U.S. citizens from “Generation X” who are interested in starting their own businesses.

Show that the equation of a line that goes through the points $\left(x_{1}, y_{1}\right)$ and $\left(x_{2}, y_{2}\right)$ is: $\frac{y-y_{2}}{y_{2}-y_{1}}=\frac{x-x_{2}}{x_{2}-x_{1}}$

The ellipse

$$\left( x ^ { 2 } / 9 \right) + \left( y ^ { 2 } / 25 \right) = 1$$

is shifted 3 units to the left and 2 units down to generate the ellipse

$$\frac { ( x + 3 ) ^ { 2 } } { 9 } + \frac { ( y + 2 ) ^ { 2 } } { 25 } = 1.$$

a. Find the foci, vertices, and center of the new ellipse. b. Plot the new foci, vertices, and center, and sketch in the new ellipse.

Find (a) the domain of each rational function f and (b) the zeroes of f, if any.

$$f ( x ) = \frac { x ^ { 2 } + 1 } { x ^ { 2 } - 1 }$$

A 250 MW fission reactor consumes half its fuel in 3.00 y. How much

$$^{235}U$$

did it contain initially? Assume that all the energy generated arises from the fission of

$$^{235}U$$

and that this nuclide is consumed only by the fission process.

(a) When a projectile is thrown at a speed

$$v_0$$

at an angle above the horizontal, which component of the launch velocity determines the maximum height reached by the projectile? (b) Do the horizontal and vertical components of the launch velocity have larger or smaller magnitudes than

$$v_0?$$

(c) If the projectile is thrown straight upward at a speed

$$v_0,$$

does it attain a greater or lesser height than that in part (a)? In each case, account for your answer. A ball is thrown upward at a speed

$$v_0$$

at an angle of

$$52^\circ$$

above the horizontal. It reaches a maximum height of 7.5 m. How high would this ball go if it were thrown straight upward at speed

$$v_0?$$

Solve the equation. Check your solution.

$$-3 = 2 + \frac{a}{11}$$

Determine whether the following statements are true and give an explanation or counterexample. One computer algebra system produces

$$\int 2 \sin x \cos x d x = sin^2x$$

. Another computer algebra system produces

$$\int 2 \sin x \cos x d x = - \cos ^ { 2 } x$$

. One computer algebra system is wrong (apart from a missing constant of integration).

You are studying some moon rocks. Some of the moon rocks are made up of jagged pieces of other rocks. The pieces are cemented together by fine, dust-sized particles called rock powder. How would you classify this type of moon rock? Explain how you used the rock's characteristics to classify it.
