The line can not be line of best fit because it's not closest to lost of the point.

A line of best fit is a straight line that minimizes the distance between it and some data. It is an output of regression analysis and can be used as a prediction tool for indicators and price movements.

Line of best fit must pass through as many as possible points on the graph. Looking at the line above is on the graph but doesn't not pass through most of the points.

The points are actually representing a value and the line must also represent the value.

Therefore the line above is not a line of best fit

Answer:

C) It cannot be the line of best fit because it is not closest to most of the points.

Step-by-step explanation:

A scatter plot is a graphical representation of a dataset in which individual data points are plotted as dots on a two-dimensional coordinate system. It is used to visually examine the relationship between two variables and identify patterns or trends in the data.

The line of best fit is a straight line that represents the general trend or pattern in a scatter plot, and minimizes the overall distance between the line and the data points.

To determine if a line on a scatter plot is the line of best fit, you can assess its alignment with the data points. The line of best fit should pass as close as possible to the majority of the data points, minimizing the overall distance between the line and the points.

From observation of the given scatter plot, the line does show a positive association, but it cannot be the line of best fit because it is not closest to most of the points.

Note: The correct line of best fit is shown in red on the attached diagram.

Researchers try to gain insight into the characteristics of a sample population by examining a sample of the population.

A sample is a subset of individuals or units taken from a larger population. Researchers use sampling methods to select a representative group of individuals from the population they are interested in studying. By studying the sample, researchers can make inferences and draw conclusions about the characteristics, behaviors, or trends that may exist within the entire population.

The goal of sampling is to obtain a sample that accurately represents the population in terms of its relevant characteristics. Researchers carefully select their samples to ensure that they are representative and minimize bias. This allows them to generalize the findings from the sample to the larger population with a certain level of confidence.

By examining a sample, researchers can collect data, analyze patterns, and draw conclusions about the population as a whole. This approach is more feasible and practical than attempting to study the entire population, especially when the population is large or geographically dispersed.

Therefore, researchers use samples to gain insight into the characteristics of a population, making option d. "Sample" the correct answer.

Integrating the above expression within the given limits will give us the desired probability. However, the calculation involves numerical integration and may require the use of specialized software or calculators.

To determine the probability that a Lucky Lumen light bulb will last between 5500 and 27500 hours, we can use the exponential distribution formula.

The exponential distribution is defined by the probability density function (PDF):

f(x) = (1/μ) * e^(-x/μ)

Where:

μ is the mean of the distribution

In this case, the mean (μ) of the distribution is given as 20,000 hours.

To find the probability that a light bulb will last between 5500 and 27500 hours, we need to calculate the integral of the PDF within that range.

P(5500 < X < 27500) = ∫[5500, 27500] f(x) dx

P(5500 < X < 27500) = ∫[5500, 27500] (1/20000) * e^(-x/20000) dx

Integrating the above expression within the given limits will give us the desired probability. However, the calculation involves numerical integration and may require the use of specialized software or calculators.

Probability of getting 5 notifications in 30 minutes: 0.0625 and Probability of getting 10 or less notifications in one hour: 0.9961

Probability of getting 5 notifications in 30 minutes:

The average number of notifications per hour is 12, so the average number of notifications in 30 minutes is 6.

Therefore, the probability of getting 5 notifications in 30 minutes is

P(5 Notifications) = (6 C 5)*(1/2^6)

P(5 Notifications) = 0.0625

Probability of getting 10 or less notifications in one hour:

The probability of getting 10 or less notifications in one hour is the sum of the probabilities of getting 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 notifications in one hour.

We can calculate this probability as

P(≤ 10 Notifications) = (12 C 0)(1/2^12) + (12 C 1)(1/2^12) + (12 C 2)(1/2^12) + (12 C 3)(1/2^12) + (12 C 4)(1/2^12) + (12 C 5)(1/2^12) + (12 C 6)(1/2^12) + (12 C 7)(1/2^12) + (12 C 8)(1/2^12) + (12 C 9)(1/2^12) + (12 C 10)*(1/2^12)

True, the joint probability of Y1 and Y2 taking on the value 1 simultaneously is 1/3.

The first dummy random variable is defined as follows:

Let X be the random variable representing the number on the first dice. Then, the dummy random variable Y1 is defined as:

Y1 = 1 if X is either 1, 2, or 3

Y1 = 0 otherwise

Similarly, the second dummy random variable is defined as:

Let Z be the random variable representing the number on the second dice. Then, the dummy random variable Y2 is defined as:

Y2 = 1 if Z is either 3, 4, 5, or 6

Y2 = 0 otherwise

Since Y1 and Y2 are independent, their joint probability distribution can be computed by multiplying their marginal probabilities.

P(Y1=1, Y2=1) = P(Y1=1) * P(Y2=1)

To compute P(Y1=1), we need to find the probability that X is either 1, 2, or 3. Since each face of a fair dice has an equal probability of appearing, we have:

P(X=1) = P(X=2) = P(X=3) = 1/6

Therefore,

P(Y1=1) = P(X=1 or X=2 or X=3) = P(X=1) + P(X=2) + P(X=3) = 3/6 = 1/2

Similarly, to compute P(Y2=1), we need to find the probability that Z is either 3, 4, 5, or 6. Again, since each face of a fair dice has an equal probability of appearing, we have:

P(Z=3) = P(Z=4) = P(Z=5) = P(Z=6) = 1/6

Therefore,

P(Y2=1) = P(Z=3 or Z=4 or Z=5 or Z=6) = P(Z=3) + P(Z=4) + P(Z=5) + P(Z=6) = 4/6 = 2/3

Thus,

P(Y1=1, Y2=1) = P(Y1=1) * P(Y2=1) = (1/2) * (2/3) = 1/3

The fraction of the box she puts in each bowl is, 1/10

Fraction is a mathematical term, which represents the portion or sub-parts of the whole thing. Basically, It has two parts: numerator and denominator.

Numerator is a number which lies on the top side, it indicates the number of equal parts taken and denominator is on the bottom side, it indicates the equal parts of the whole number.

To find the fraction of the box that Evangeline puts in each bowl, we need to divide the total amount of nuts in the box by the number of bowls.

The amount of nuts she has is 3/5 of a box.

To find the amount of nuts in each bowl, we need to divide 3/5 by 6:

(3/5) ÷ 6

To divide by a fraction, we can multiply by its reciprocal:

= (3/5) ÷ (6/1)

= (3/5) x (1/6)

Multiplying across, we get:

= (3/5) x (1/6)

= 3/30

Explanation:

3x² + 24x - 24 = 0

factor the coefficient

3(x² + 8x) -24 = 0

Halve the second term and square it

3(x + 4)² -24 -3(4)² = 0

simplify the answer

3(x + 4)² -72 = 0

add 72 on both sides

3(x + 4)² = 72

divide both sides by 3

(x + 4)² = 24

square root both sides

x + 4 = ±√24

subtract both sides by 4

x = -4 ± 2√6

Factor out 3:

\(\implies 3(x^2+8x-8)=0\)

Divide both sides by 3:

\(\implies x^2+8x-8=0\)

Add 8 to both sides:

\(\implies x^2+8x=8\)

\(\textsf{Add }\: \left(\dfrac{b}{2}\right)^2\: \textsf{ to both sides}:\)

\(\implies x^2+8x+\left(\dfrac{8}{2}\right)^2=8+\left(\dfrac{8}{2}\right)^2\)

\(\implies x^2+8x+16=8+16\)

\(\implies x^2+8x+16=24\)

Factor the left side:

\(\implies (x+4)^2=24\)

Square root both sides:

\(\implies x+4=\pm2\sqrt{6}\)

Subtract 4 from both sides:
