The direction of relationship changes at least once.

Step-by-step explanation:

Curvilinear relationship is a relationship between two variables where if one variable increases the other variable also increases but up to certain point after which one variable increases and other decreases. This type of relationship is referred as non monotonic function.

The answer is  True, the percentile rank identifies the percentile of a particular value within a set of data.

The percentile rank is a measure that identifies the percentage of scores in a distribution that are equal to or lower than a given score. It is calculated by dividing the number of scores that are equal to or lower than the given score by the total number of scores in the distribution, and multiplying the result by 100 to obtain a percentage. The percentile rank can be used to compare individual scores to the rest of the distribution, and can provide useful information about the relative standing of a score within a particular group or population. Therefore, it is true that the percentile rank identifies the percentile of a particular value within a set of data.

Answer: 302 cm2

Step-by-step explanation:

Hi, to answer this question we have to calculate the surface area of the cubes and the rectangular prism, and the then add them (minus the overlaps)

Surface area of a cube (SAC)= 6 x side length ^2  

Since one side of each cube is covered by each other, we simply have to multiply the area of one side by 5 instead of 6.

SAC = 5 x (2)^2 = 20 cm2

Since both cubes are equal, we simply multiply it by 2:

20 x 2 = 40 cm2 (surface area of the 2 green cubes)

Surface Area of a rectangular prism (SAP) = 2wl + 2lh + 2hw

Where:

w = width (5); l = length (11); h = height (5)

SAP = 2 (5x 11) + 2 (11 x5) + 2 (5x5) = 110+110+50=270 cm2

Finally, adding both surface areas, and subtracting the base area of the bottom cube covered by the prism multiplied by 2 ( overlap )

270+40-2(4) = 302 cm2

Setting x1 to zero in the equation 2x1 + 1x2 = 30 results in the value of x2 being 30.

The given equation is 2x1 + 1x2 = 30, where x1 and x2 represent variables. To find the value of x2 when x1 is set to zero, we substitute x1 with zero in the equation.

By replacing x1 with zero, we have 2(0) + 1x2 = 30. Simplifying further, we get 0 + 1x2 = 30, which simplifies to x2 = 30.

When x1 is set to zero, the equation reduces to a simple linear equation of the form 1x2 = 30. Therefore, the value of x2 in this scenario is 30.

Setting x1 to zero effectively eliminates the contribution of x1 in the equation, allowing us to focus solely on the value of x2. In this case, when x1 is removed from the equation, x2 becomes the sole variable responsible for fulfilling the equation's requirement of equaling 30. Thus, x2 is determined to be 30.

The statement that is true of the sample size for nonprobability samples is that it is typically small.

Nonprobability sampling methods are often used when it is not feasible or practical to obtain a large sample that is representative of the population.

Nonprobability samples are selected based on criteria other than random selection, such as convenience, judgment, or purposive sampling. These methods are commonly used in qualitative research or when studying hard-to-reach populations.

Since nonprobability samples do not guarantee representativeness, the focus is often on in-depth exploration rather than generalization to a larger population. As a result, researchers often work with smaller sample sizes that are more manageable and allow for in-depth analysis of the selected cases or individuals.

Answer:

72 points

Step-by-step explanation:

To find the final score, add the score of correct answers with score of incorrect answers.

Score of 1 incorrect answer = -2

Score of 6 incorrect answers = 6 * (-2)

                                                 = -12

Total questions = 20

number of questions he answered correctly  = Total questions - incorrect answers

                         = 20 - 6

                         = 14

Score for 1 correct answer = 6 points

Score for 12 correct answers = 14 * 6

                                                = 84 points

Final score = Score for correct answers + score for incorrect answers

                   = 84 + (-12)

                  = 72 points

If Freddie got six problems incorrect, you multiply six times two to get twelve as your product. Then, you find the number of questions Freddie got right by subtracting the number he got wrong from the total number of questions… fourteen. Multiply fourteen by the points earned for each correct answer, six, to get eighty-four. then you take away 12 to get 72 as Freddie's answer. hope this helps.

The probability of event A given event B, denoted as P(A | B), is 0.750. The probability of event B given event A, denoted as P(B | A), is 0.900. A and B are not independent events because the conditional probabilities P(A | B) and P(B | A) are not equal to the marginal probabilities P(A) and P(B), respectively.

To find P(A | B), we use the formula:

P(A | B) = P(A ∩ B) / P(B)

In this case, P(A ∩ B) = 0.45 and P(B) = 0.60.

Plugging these values into the formula, we get

P(A | B) = 0.45 / 0.60 = 0.750.

To find P(B | A), we use the formula:

P(B | A) = P(A ∩ B) / P(A)

Here, P(A ∩ B) = 0.45 and P(A) = 0.50.

Substituting the values, we find

P(B | A) = 0.45 / 0.50 = 0.900.

A and B are not independent because the probabilities of A and B are affected by each other. If A and B were independent, then P(A | B) would be equal to P(A), and P(B | A) would be equal to P(B). However, in this case, both P(A | B) and P(B | A) differ from their respective marginal probabilities. Therefore, A and B are dependent events.

The correct algebraic expression for f(x) * g(x) is 5x^3 - 11x^2 + 17x - 3.

To find the algebraic expression for f(x) * g(x), we need to multiply the two functions together.
Given: g(x) = x^2 - 2x + 3 and f(x) = 5x - 1
To multiply these functions, we can distribute each term of f(x) to every term in g(x).
First, let's distribute 5x from f(x) to each term in g(x):
5x * (x^2 - 2x + 3) = 5x * x^2 - 5x * 2x + 5x * 3
This simplifies to:
5x^3 - 10x^2 + 15x
Now, let's distribute -1 from f(x) to each term in g(x):
-1 * (x^2 - 2x + 3) = -1 * x^2 + (-1) * (-2x) + (-1) * 3
This simplifies to:
-x^2 + 2x - 3
Now, let's add the two expressions together:
(5x^3 - 10x^2 + 15x) + (-x^2 + 2x - 3)
Combining like terms, we get:
5x^3 - 11x^2 + 17x - 3

So ice cream on this particular beach causes more sharks to come closer to shore and attack. That's the premise.

I'd like to say it is a coincidence, or the data is biased in some way, but there is no way of telling without checking out the stats (which I would guess there are none).

Perhaps sharks like sugar and lot of someones drop their ice cream cones in the water. It's a test. Or it could be made into one.

Perhaps the sharks are annoyed by the ice cream and take it out on the person holding the ice cream. Again it's a test.

Perhaps they smell the ice cream and are attracted to it. I wouldn't want to test this with offering a shark a sugar cube put in water.

1. The probability that the point chosen is in the triangle is 0.1 (nearest tenth)

2. The probability that the point is in the square is 0.2( nearest tenth)

A probability is a number that reflects the chance or likelihood that a particular event will occur. The certainty for an event is 1 which is equivalent to 100%.

Probability = sample space / total outcome

total outcome is the area of rectangle , which is

A = l× w

= 12 × 8

area of the rectangle = 1/2 bh

= 1/2 × 4 × 5

= 2 × 5

= 10

Area of the square = 4×4

= 16

1. Probability the the point will be in the triangle= 10/96 = 5/48

= 0.1( nearest tenth)

2. probability the the point will be in the square =

16/96 = 1/6

Implementing a new system into an organization module by module is called a​ phased approach.

A phased approach is one of two common methods used to develop an ERP system solution. In this strategy, the system's functionalities are introduced in a certain order, gradually replacing previous systems and processes.

This frequently indicates that a business starts off with core functionality that is given top attention, and then other applications are gradually added in stages over time. An alternative implementation strategy, however, uses an all-at-once model in which the system and all apps "Go Live" simultaneously.

The optimal implementation plan for your firm will depend on the needs, goals, and strategies you have for it. This might involve a hybrid strategy where crucial functionality is added to the core ERP programs first, and then desirable features are added later on in a staged implementation. By considering all of your options, your firm can decide which will serve its interests the most effectively.
