The characters in the trailer would need to reach an initial velocity of at least 13.4 m/s in order to safely jump the crevice and escape the displacer beast.
In one of the trailers, the characters narrowly escape the displacer beast by jumping over a crevice. To calculate the minimum velocity required for the jump, we can use the equation for the distance of an object thrown vertically upwards:
v1 = √(2gh)
where v1 is the initial velocity, g is the acceleration due to gravity (9.81 m/s2), and h is the height of the crevice.
For example, if the crevice is 6 meters deep, the required initial velocity to safely jump over it would be:
v1 = √(2 * 9.81 * 6)
v1 = 13.4 m/s
Therefore, the characters in the trailer would need to reach an initial velocity of at least 13.4 m/s in order to safely jump the crevice and escape the displacer beast.

Maxine spent 15 hours doing her homework last week. This week she spent 18 hours doing homework. She says that she spent 120% more time doing homework this week. Is she correct? Show your work to justify your decision.
Answer:
Yes
Explanation: 120 % = 1.2
If Maxine is correct, then she spent 1.2
times the hours she did homework than last week.
15 ⋅ 1.2 = 18.0 = 18
15 hours ⋅ 1.2 = 18.0 hours = 18 hours
This means that Maxine is correct.

There are 20 people trying out for a team. How many ways can you make randomly select for people to make a team?
There are 15,504 ways to randomly select a team of 5 people from a group of 20 people
If there are 20 people trying out for a team, the number of ways to select a team of n people can be calculated using the formula for combinations, which is:
C(20, n) = 20! / (n! * (20 - n)!)
where C(20, n) represents the number of ways to select n people from a group of 20 people.
For example, if we want to select a team of 5 people, we can plug in n = 5 and calculate:
C(20, 5) = 20! / (5! * (20 - 5)!) = 15,504
Therefore, there are 15,504 ways to randomly select a team of 5 people from a group of 20 people. Similarly, we can calculate the number of ways to select teams of different sizes by plugging different values of n into the formula for combinations.

C-reactive protein (CRP) is a substance that can be measured in the blood. Values increase substantially within 6 hours of an infection and reach a peak within 24 to 48 hours after. In adults, chronically high values have been linked to an increased risk of cardiovascular disease. In a study of apparently healthy children aged 6 to 60 months in Papua New Guinea, CRP was measured in 90 children. The units are milligrams per liter (mg/l). Here are the data from a random sample of 40 of these children.

b.
C-reactive protein (CRP) tiers were measured in a pattern of apparently healthy children elderly 6 to 60 months in Papua New Guinea. Given the presence of many zero values within the facts, the implication may not be a good characterization of the center of this distribution. The median could be an extra suitable degree in this case.
A. In this situation, it is not suitable to apply the imply as an amazing characterization of the middle of the distribution. The cause is that the statistics consist of a large number of 0 values, on the way to heavily have an impact on the suggestion.
Since CRP values increase considerably throughout an infection, the presence of many 0 values suggests that a sizable part of the youngsters within the look-at aren't presently experiencing contamination. Therefore, the implications can be heavily prompted by way of the massive quantity of zeros, resulting in a faulty representation of the center of the distribution.
B. To higher signify the middle of this distribution, it might be extra suitable to use the median. The median is not affected by extreme values or outliers as an awful lot because they imply, and it represents the center fee of the statistics when its miles are organized in ascending or descending order.
In this situation, the median will provide a more robust degree of the principal tendency of the CRP values, specifically considering the presence of many 0 values in the dataset.

what is the term for the value that occurs most often in a series of numbers?
The term for the value that occurs most often in a series of numbers is called the mode.
The mode is one of the three main measures of central tendency, along with the mean and the median. It is a useful descriptive statistic that can provide insights into the characteristics of a dataset.
To find the mode of a set of data, you first need to arrange the data in order, either in increasing or decreasing order. Then, you simply identify the most frequent data point, which is the mode. In some cases, there may be more than one mode if multiple data points occur with the same maximum frequency.
The mode is particularly useful when dealing with categorical or nominal data, where there are distinct categories or values that cannot be ordered in a meaningful way. For example, the mode can help identify the most popular color among a group of people or the most common type of car on a given street. It can also be used for continuous data, although it may be less useful in this case than the mean or median.

Pat Brown bought a Chevy truck for $28,000 with an estimated life of 5 years. The residual value of the
truck is $3,000. Assume a straight-line method of depreciation. (a) What will be the book value of the
truck at the end of year 3? (b) If the Chevy truck was bought the first year on April 12, how much
depreciation would be taken the first year?
First thing you need to do is to find out the yearly depreciation amount:
Annual depreciation = (Cost of truck - Residual value) / Useful life
= (28,000 - 3,000) / 5
= $5,000
At the end of 3 years, the value of the truck would be:
= Cost of truck - (Depreciation amount x number of years)
= 28,000 - (5,000 x 3)
= $13,000
If the truck was bought on April 12, only depreciation by the number of days left in that year:
= Annual depreciation / Number of days in a year x Number of days left in the first year
= 5,000 / 365 x 263
= $3,602.74
In conclusion, the truck will be worth $13,000 in 3 years.

What are the odds of hitting an asteroid in the asteroid belt?
The odds of hitting an asteroid in the asteroid belt are quite low.
To explain this further, let's consider the following steps:
Understand the context: The asteroid belt is located between the orbits of Mars and Jupiter and contains millions of asteroids varying in size.Space is vast: Despite the presence of numerous asteroids, the asteroid belt is incredibly spacious. The average distance between individual asteroids is hundreds of thousands of kilometers, making the odds of a collision very low.NASA's experience: Spacecraft, such as those sent by NASA, have successfully navigated through the asteroid belt without any collisions. The low probability of impact is attributed to the vast distances between asteroids and the ability to plan trajectories that avoid potential collisions.In summary, the odds of hitting an asteroid in the asteroid belt are quite low due to the vast distances between individual asteroids and the ability to carefully plan spacecraft trajectories.

for the problem of approximating the probability of a 6 in rolling a die, a. identify an appropriate family of distributions;
The appropriate family of distributions to approximate the probability of rolling a 6 on a fair die is the discrete uniform distribution, which assumes equal probabilities for each outcome. In this case, the probability of rolling a 6 would be approximately 1/6 based on the assumption of fairness.
For the problem of approximating the probability of rolling a 6 on a fair die, an appropriate family of distributions to consider is the discrete uniform distribution.
The discrete uniform distribution is commonly used to model situations where each outcome has an equal probability of occurring. In the case of rolling a fair die, the die has six equally likely outcomes (numbers 1 to 6).
Each outcome has a probability of 1/6 of occurring, making the discrete uniform distribution a suitable choice.
By assuming a discrete uniform distribution, we can assign equal probabilities to each outcome (1/6 for rolling a 6) and approximate the probability of rolling a 6 based on the assumption of fairness.

given the relation R = {P, Q, R, S, T, U, V, W, X, Y, Z} and the set of functional dependencies F = { {P, R}→{Q}, {P}→{S, T}, {R}→{U}, {U}→{V, W}, {S}→{X, Y}, {U}→{Z}}. Find the key for R? Decompose R into 2NF and then 3NF relations and then to BCNF (show the steps of decomposition steps clearly).
The resulting relations are:
R1({P, R, Q, U, Z})
R2({P, S, T}, {R → R2})
R3({U, V, W}, {R → R3})
R4({S, X, Y}, {P → R4}) or ({R → R4})
To find the key for R, we need to determine which attribute(s) uniquely identify each tuple in R. We can do this by computing the closure of each attribute set using the given functional dependencies F.
Starting with P, we have {P}+ = {P, R, U, V, W, Z}, since we can derive all other attributes using the given functional dependencies. Similarly, {R}+ = {R, U, V, W, Z}. Therefore, both {P} and {R} are candidate keys for R.
To decompose R into 2NF, we need to identify any partial dependencies in the functional dependencies F. A partial dependency exists when a non-prime attribute depends on only a part of a candidate key. In this case, we can see that {P}→{S, T} is a partial dependency since S and T depend only on P but not on the entire candidate key {P,R}.
To remove the partial dependency, we can create a new relation with schema {P, S, T} and a foreign key referencing R. This preserves the functional dependency {P}→{S,T} while eliminating the partial dependency.
The resulting relations are:
R1({P, R, Q, U, V, W, Z})
R2({P, S, T}, {R → R2})
To decompose R into 3NF, we need to identify any transitive dependencies in the functional dependencies F. A transitive dependency exists when a non-prime attribute depends on another non-prime attribute through a prime attribute.
In this case, we can see that {U}→{V,W} is a transitive dependency since V and W depend on U through the prime attribute R. To eliminate this transitive dependency, we can create a new relation with schema {U, V, W} and a foreign key referencing R.
The resulting relations are:
R1({P, R, Q, U, Z})
R2({P, S, T}, {R → R2})
R3({U, V, W}, {R → R3})
To decompose R into BCNF, we need to identify any non-trivial functional dependencies where the determinant is not a superkey. In this case, we can see that {S}→{X,Y} is such a dependency since S is not a superkey.
To remove this dependency, we can create a new relation with schema {S, X, Y} and a foreign key referencing P (or R). This preserves the functional dependency while ensuring that every determinant is a superkey.
The resulting relations are:
R1({P, R, Q, U, Z})
R2({P, S, T}, {R → R2})
R3({U, V, W}, {R → R3})
