the answer is below

Explanation: The independent variable is the experimental factor which is manipulated and the variable whose effects are being studied. The dependent variable is a variable that could change due to the independent variable. The independent variable is the different ways that Jennifer treats her puppies in order to bring them closer to what she wants in the agility competition. The dependent variable is how they puppies perform each day.

Behavioral shaping is a conditioning procedure where the reinforcers guide behavior toward closer and closer approximations of a desired behavior. Jennifer guided Sasha closer and closer to completing a behavior correctly, thus utilizing shaping in order to bring the puppy closer to what she wanted.

Something that is persistent remains over time; this is a key characteristic of DDT, which also happens to be a pollutant/pesticide. DDT is able to persist in an environment (as a pollutant) in part due to a phenomenon known as biological magnification. In simpler terms. once DDT enters an ecosystem/trophic structure, it gets worse as you go up the trophic levels; in other words, this means that the worst effects/concentrations of the pesticide will be felt in the uppermost trophic levels (your consumers rather than producers).

The basis for this, however, lies in the fact that organisms of a trophic structure/ecosystem consume each other; they feed on each other to survive (e.g. consumers feeding on producers, higher-level consumers feeding on lower-level consumers, etc.). Thus, once DDT gets into an ecosystem, it can only persist and spread in that ecosystem. Hope this helps :)

The proportion of the available motorcycles that Molly can afford is 60%.

The 30th percentile for the motorcycle is $11920

It should be noted that $25,000 is considered an outlier because it is greater than $24792

Since, mean, μ =  $14,000 and standard deviation, σ = $4,000, the standard variable Z or x = $15,000 will be:

Z = (x - μ)/σ

Z = (15000 - 14000)/4000

Z = 0.25

We then check the table and see that it implies that Molly can buy 60% of the available motorcycles.

The 30th percentile for the prices of motorcycles of this type corresponds to a value of Z = -0.52. This will then be:

x = μ + Z*σ

x = 14000 + (-0.52) × 4000

x = $11920

Lastly, the third quartile value when added to 1.5 x IQR will be equal to:

= 16698 + (1.5 × 5396) = $24792

Therefore, $25,000 is considered an outlier because it is greater than $24792

Yes, the business journal is interpreting the probability correctly, because 3 out of 5 randomly selected Internet users that will use the mobile payment application, means that, 3/5, or 0.6 of probability. That is exactly the probability reported by the business journal.

Explanation:

Probability that Internet users in the United States will use a mobile payment app is 0.60.

The algorithm's runtime has been divided into two main categories are given below.

Explanation:

Polynomial runtime would be defined as almost any run time that doesn't even improve quicker than n^k, including fixed time (n^0), logarithmic time (log2{n}), linear (n^1), quadratic (n^2), as well as another polynomial of higher degrees (such as n^3).  The runtime that grows more than n^k and contains exponential time including such (2^n), factorial time (n!), or anything else is super polynomial runtime.It seems it is perceived that polynomial runtime seems to be rational as well as super polynomial growth in order are rendered irrational. It is not necessarily ideal to have a polynomial run time, but it's least theoretically possible.

Then maybe we can easily see by the information collected that perhaps the algorithm is increasing at either the frequency of 20×n. At which, across every iteration, n seems to be the input dimension. This suggests that perhaps the runtime specified seems to be of a polynomial category, therefore means that even this technique executes within a rational period.

To generate objective knowledge about any area it is important to use the scientific method. The scientific method uses measurement, analysis, observation, and experimentation to obtain objective data to validate the hypotheses and generate knowledge.

In this case, City University carried out a scientific investigation to verify that its students were happy throughout the time in the university. For the investigation, they used an instrument that evaluates satisfaction. The results indicate that the senior-students are happier than the first-year students, for that the university officials conclude that the students are happier when they attend university for a longer time. This is convenient to attract new students and not change to another study center.

I hope this information can help you.

Answer:

(a) Which island has an absolute advantage in producing coconuts? Explain.
No island has absolute advantage in producing coconuts because both Zeetopia and Freshland can produce equal number of coconuts (50 each).

(b) Which island has a comparative advantage in producing coconuts? Explain.
Freshland has a comparative advantage in producing coconuts. Freashland's opportunity cost of producing coconuts (30/50 = 0.6 mangoes) is lower than Zeetopia's 60/50 = 1.2 mangoes). So, Freshland has a comparative advantage in producing coconuts

(c) Assume Zeetopia and Freshland decide to specialize according to their comparative advantages and 1 ton of coconuts is exchanged for 1 ton of mangoes. Are specialization and trade under these terms beneficial to both Zeetopia and Freshland? Explain.

Yes, the terms of trade (1 ton of coconut = 1 ton of mangoes) are beneficial for both islands.
For Zeetopia, opportunity cost of 1 ton of coconut is1.2 tons of mangoes (60/50 = 1.2). So, when it specializes in mangoes, it should get 1 ton of coconut for less than 1.2 tons of mangoes (or, it should give up less than 1.2 tons of mangoes to obtain 1 ton of coconuts). So, 1 ton of coconut = 1 ton of mangoes is beneficial for Zeetopia.
Similarly, the opportunity cost of 1 ton of coconuts for Freshland is 0.6 tons of mangoes. So, when it specializes in coconuts, it should get more than 0.6 tons of mangoes in return for 1 ton of coconuts. So, 1 ton of coconut = 1 ton of mangoes is beneficial for Freshland.

(d) The graph:
A biologist is growing bacteria for a lab experiment. There are 10 mg of bacteria in a controlled en
(e) Point X is unattainable for Freshland but feasible and inefficient for Zeetopia.

There is a probability of 89.44% that more than 3.75 gallons are used for any wash cycle.

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

z=\frac{x-\mu}{\sigma} \\\\Where\ x\ is\ raw \ score,\mu=mean,\sigma=standard\ deviation\\\\\\Given\ that\ \mu=4,\sigma=0.2:For\ x3.75\\\\z=\frac{3.75-4}{0.2}=-1.25\\\\

From the normal distribution table, P(x > 3.75 ) = P(z > -1.25) = 1 - P(z < 1.25) = 1 - 0.1056 =89.44%
