William was playing a board game that had a spinner with six equal ­sized
sections. Three of the sections were red, two sections were blue, and one
section was yellow. Find the probability that he landed on a purple section.

To evaluate the integral ∫ x^3 (7x^4)^4 dx using the substitution u = 7x^4, the answer: (1/28)(1/5)(7x^4)^5 + c. Simplifying further, we obtain (1/140)x^20 + c, where c represents the constant of integration.

Making the substitution u = 7x^4 simplifies the integral. We express the integral in terms of u and then differentiate u with respect to x to find du. Substituting u and du into the integral, we obtain ∫ (1/28)u^4 du. Evaluating this integral and substituting back for u, we finally arrive at the answer: (1/28)u^5 + c, where c represents the constant of integration. We start by substituting u = 7x^4 into the integral, which gives us ∫ x^3 (7x^4)^4 dx = ∫ x^3 u^4 dx. To proceed, we need to express dx in terms of du, so we differentiate u with respect to x: du/dx = d/dx (7x^4) = 28x^3. Rearranging, we have dx = du/(28x^3). Substituting dx and u into the integral, we obtain ∫ x^3 (7x^4)^4 dx = ∫ x^3 u^4 (1/(28x^3)) du. Simplifying, the x^3 and x^3 terms cancel out, leaving us with ∫ u^4/28 du. Integrating ∫ u^4/28 du gives us (1/28)∫ u^4 du. Applying the power rule of integration, we add 1 to the exponent and multiply by the reciprocal of the new exponent, resulting in (1/28)(1/5)u^5 + c. Finally, substituting back for u, we arrive at the answer: (1/28)(1/5)(7x^4)^5 + c. Simplifying further, we obtain (1/140)x^20 + c, where c represents the constant of integration.

Answer:

D

Step-by-step explanation:

To determine the elasticity, we need to differentiate both sides of the equation with respect to x and then multiply by (x/y):

Differentiating the equation with respect to x:

3.45 * d/dx(log(y)) = 87.6 * d/dx(log(x))

Using the property of logarithmic differentiation, we have:

3.45 * (1/y) * dy/dx = 87.6 * (1/x) * dx/dx

Simplifying and rearranging the equation:

(1/y) * dy/dx = (87.6/3.45) * (1/x)

(1/y) * dy/dx = 25.43/x

Multiplying both sides by (x/y):

dy/dx = (25.43/x) * (x/y)

dy/dx = 25.43/y

The elasticity is given by the ratio of the derivative of y with respect to x to the ratio of y to x. In this case, the elasticity is:

Elasticity = dy/dx * (x/y)

Substituting the value we obtained for dy/dx:

Elasticity = (25.43/y) * (x/y)

Elasticity = 25.43 * (x/y^2)

Therefore, the elasticity is given by 25.43 times the ratio of x to y squared.

the formula for dy/dx in terms of x and y is:

dy/dx = -3/(x) * y

the value of dy/dx at the point (81, 16) is - 16/27

To find the formula for dy/dx in terms of x and y, we'll differentiate the given equation with respect to x:

\((90x^{(3/4)})(y^{(1/4)})\) = 4860

Differentiating both sides with respect to x:

d/dx [\((90x^{(3/4)})(y^{(1/4)})\)] = d/dx [4860]

Using the product rule for differentiation:

(3/4)(90)\((x^{(-1/4)})(y^{(1/4)})\) + (90\(x^{(3/4)\))(1/4)(\(y^{(-3/4)\))(dy/dx) = 0

Simplifying:

(3/4)(90)\((x^{(-1/4)})(y^{(1/4)})\)  + (90\(x^{(3/4)\))(1/4)(\(y^{(-3/4)\))(dy/dx) = 0

Rearranging terms and isolating dy/dx:

(dy/dx) = -[(3/4)(90)\((x^{(-1/4)})(y^{(1/4)})\)] / [(90\(x^{(3/4)}\))(1/4)(\(y^{(-3/4)\))]

Simplifying further:

(dy/dx) = -3/(x) * y

Therefore, the formula for dy/dx in terms of x and y is:

dy/dx = -3/(x) * y

Now let's find the value of dy/dx at the point (81, 16):

Substituting x = 81 and y = 16 into the formula:

dy/dx = -3/(81) * 16

      = -3/81 * 16

      = - 16/27

Therefore, the value of dy/dx at the point (81, 16) is - 16/27

In Herrnstein's matching equation, the letters and numbers to the left of the equals sign refer to behaviour.

THE MATCHING LAW

Herrnstein's Experiment Herrnstein (1961) conducted an experiment with pigeons in a room with two response buttons, red and white. Each key was assigned its own VI gain schedule. For example, under one condition, the left button pick was boosted on a VI 135 second schedule, and the right button pick was boosted on a VI 270 second schedule.

After the birds have learned as much as possible about this electoral situation, how do they distribute their responses? We trained them for days and then measured their reactions. As is often the case with VI schedules, birds returned many responses for each reinforcer received. Most interesting, however, is that in this condition, where two-thirds of the reinforcers came from the left button, the birds performed about two-thirds of the responses with the left button. That is, the proportion of left button responses equaled or matched the proportion of reinforcers delivered by the left button. In another condition, two birds received only about 15% of reinforcers from the left key and responded about 15% to that key.

Based on these results, Herrnstein proposed the following general principle for individual behavior when presented with alternative sequences. So, what you think makes sense rather than other options available at that particular moment.

M = -26

Then the length of MP is:

-5 - (-26) = 21

And MN is 2/7 of that, then:

Step-by-step explanation:

Among the provided answer options, the closest value to -0.555 is -0.55, which is option c. Therefore, option c (-0.55) is the value of c that satisfies P(Z ? c) = 0.71.

The notation P(Z ? c) represents the probability that a standard normal random variable Z is less than or equal to c. To find the value of c that corresponds to P(Z ? c) = 0.71, we need to determine the Z-score associated with this probability.

Using a standard normal distribution table or a calculator, we can find that a Z-score of approximately 0.555 corresponds to a cumulative probability of 0.71. However, since we are looking for the value of c in P(Z ? c), we need to consider the opposite inequality.

Step-by-step explanation:

The student has incorrectly added 8 on both sides of the equation instead of subtracting it.

The general form of an equation is given as,

(y ₋ y₁)=m(x ₋ x₁)

where (x₁,y₁) is the point through which the line passes and m is the slope of the line.

Given that a line has a slope of -6 and passes through the point (2, –8). Therefore, substitute the slope and point in the above general form of the line and simplify.

(y ₋ y₁)=m(x ₋ x₁)

[y ₋ (-8)] = (-6)(x ₋ 2)

y + 8 = -6x + 12

Subtract 8 from both sides of the equation,

y + 8 - 8 = -6x + 12 - 8

y = -6x + 4

Now, if the steps are compared it can be seen that parenthesis are not opened properly and instead of subtracting 8, it is added to both sides of the equation.

Hence, the student has incorrectly added 8 on both sides of the equation.

Answer:

Step-by-step explanation:

You want the equation for a line through (2, -3) perpendicular to the line x -5y -8 = 0, written in point-slope form and in general form.

The slope of the given line can be found by solving for y:

  x -8 = 5y

  1/5x -8/5 = y

This tells us the given line has a slope of 1/5. That means the perpendicular line's slope will be the opposite reciprocal, or ...

  m = -1/(1/5) = -5

The equation for a line with slope m through point (h, k) is ...

  y -k = m(x -h)

Then the desired line is ...

  y +3 = -5(x -2) . . . . . . . line with slope -5 through point (2, -3)

Making the right side of the equation be zero will give the desired form.

  y +3 +5(x -2) = 0

  5x +y -7 = 0 . . . . . . . . simplify to general form

The sequence of transformations that proves trapezoid HJKL and trapezoid QPRS are similar is a dilation by a scale factor of 2 about vertex K followed by a reflection across the y-axis, which is option D.

Two figures are similar if their corresponding angles are congruent and their corresponding sides are proportional. The two trapezoids have congruent angles, since they are both trapezoids and have the same parallel bases. Therefore, we only need to show that their corresponding sides are proportional.

To do this, we need to apply a series of transformations that map trapezoid HJKL onto trapezoid QPRS. Looking at the two trapezoids, we can see that a dilation by a scale factor of 2 about vertex K would make the sides of trapezoid HJKL proportional to the corresponding sides of trapezoid QPRS. We can then reflect the resulting figure across the y-axis to make the sides of the trapezoids correspond in the same order. Therefore, the sequence of transformations that proves the two trapezoids are similar is a dilation by a scale factor of 2 about vertex K followed by a reflection across the y-axis, which is option D.

If  a deadly disease infected the hummingbird population, what would most likely happen to the plants option (b) They would become endangered

If a deadly disease infected the hummingbird population, it would most likely lead to a decrease in the pollination of plants that rely on hummingbirds for pollination. Without the hummingbirds to transfer pollen between flowers, these plants would have a reduced rate of successful pollination, which would result in a decrease in their ability to reproduce.

However, it is unlikely that the plants would die within hours or become endangered immediately, nor would they need to migrate. The effect of the loss of hummingbird pollinators on the plants would depend on the specific plant species, their pollination requirements, and the availability of alternative pollinators. Some plants may be more adaptable to using alternative pollinators, while others may suffer more severe consequences. It is also possible that the loss of hummingbirds could lead to a decline in the populations of other animals that depend on the plants, creating a ripple effect in the ecosystem.

Therefore, the correct option is (d) They would become endangered
