You use a line of best fit for a set of data to make a prediction about an unknown value. The correlation coefficient for your data set is 0. How confident can you be that your predicted value will be reasonably close to the actual value?
Responses

I can’t be confident at all; this is about as close to a random guess as you can get.

I can be a little confident; it might be close, or it might be way off.


I can be very confident; it will be close, but it probably won’t be exact.

Answers

Answer 1

The correct option regarding the correlation coefficient is that A. I can’t be confident at all; this is about as close to a random guess as you can get.

What is a correlation coefficient?

The correlation coefficient is a statistical measure of the strength of a two-variable linear relationship. Its values can range between -1 and 1. A correlation coefficient of -1 denotes a perfect negative, or inverse, correlation, in which values in one series rise while those in the other fall, and vice versa.

A coefficient of one indicates that there is a perfect positive correlation, or a direct relationship. A correlation coefficient of 0 indicates that no linear relationship exists. In science and finance, correlation coefficients are used to assess the degree of association between two variables, factors, or data sets.

In this case, the fat that the person gets 0 implies that it's probably a random guess. In conclusion, the correct option is A.

What is a geometric sequence?

In a geometric sequence the ratio of any two consecutive terms are equal. This ratio is known as the common ratio of the sequence.

Given that,

a₁ = 50 and aₙ = aₙ₋₁ ÷ 2

The first five terms are a₁, a₂, a₃, a₄  and a₅.

All the terms can be written using  aₙ = aₙ₋₁ ÷ 2 as follows,

a₂ = a₁ ÷ 2

⇒ a₂ = 50 ÷ 2

⇒ a₂ = 25

a₃ = a₂ ÷ 2

⇒ a₃ = 25 ÷ 2

⇒ a₃ = 12.5

a₄ = a₃ ÷ 2

⇒ a₄ = 12.5 ÷ 2

⇒ a₄ = 6.25

a₅ = a₄ ÷ 2

⇒ a₅ = 6.25 ÷ 2

⇒ a₅ = 3.125

Pool B started with 4800 liters of water, and 30 liters per minute are being (Drained out or Pumped back in)

The amount of water after x minutes is more in which pool? Pool A or Pool B?

Answers

Amount of water after x minutes is more in pool B.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given,

Pool A started with 5000 liters of water, and 50 liters per minute are being.

Pool B started with 4800 liters of water, and 30 liters per minute are being.

5000-50x=4800-30x

Add 30x on both sides

5000-50x+30x=4800-30x+30x

5000-20x=4800

5000-4800=20x

200=20x

Divide both sides by 20

20=x

Now substitute x in pool A equation

5000-50x

5000-50(20)=5000-1000

Pool A =4000

Now substitute x in pool B equation

4800-30x

4800-30(20)

Pool B =4200

4200>4000

According to the question,

We have the following information:

We have a figure where angle MCJ is 130°.

Now, we can extend the two given lines as imaginary lines. After extending the lines, we will find that these lines are parallel and the lines are being cut by another line.

We know that in this case the alternate interior opposite angles are equal and the sum of consecutive alternate interior angles is 180°.

Now, ∠MCJ and ∠CMB are alternate interior opposite angles and thus they are equal.

p = Probability of success in the single trial of the events

We are given;

p = 80% = 0.8

A line passes through the points (–5, –4) and (0, 4). What is its equation in slope-intercept form?

Answers

Considering the expression of a line, the equation of the line that passes through the pair of points (-5,-4) and (0,4) is y=8/5x + 4.

Linear equation

A linear equation o line can be expressed in the form y = mx + b

where

x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.

Knowing two points (x₁, y₁) and (x₂, y₂) of a line, the slope m of said line can be calculated using the following expression:

m= (y₂ - y₁)÷ (x₂ - x₁)

Substituting the value of the slope m and the value of one of the points in the expression of a linear equation, the value of the ordinate to the origin b can be obtained.

Equation in slope-intercept form in this case

Being (x₁, y₁)= (-5, -4) and (x₂, y₂)= (0,4), the slope m can be calculated as:

m= (4 - (-4))÷ (0 - (-5))

m= (4 + 4)÷ (0 +5)

m= 8÷ 5

m= 8/5

Considering point 2 and the slope m, you obtain:

4= 8/5×0 + b

4= 0 +b

4= b

Answers

a) The mean distribution is 5.295.

b) The standard deviation is 0.1026

c) The probability that the child will be older than 5 years old is 0.7657

d) The probability that the child's age is between 4.84 and 5.34 is  0.4504

e) At the 9th percentile, the age of the child is 5.739 years old.

Given interval distribution is

4.74 - 5.85.

a) Firstly, we will find the mean distribution,

Mean distribution = Sum of intervals / Number of intervals

= 4.74+5.85 / 2

= 5.295.

Hence, the mean distribution is 5.295.

b) Now, we will find the standard deviation,

We use the formula:

SD = [tex]\sqrt{\frac{(b-a)^{2} }{12} }[/tex]

b = 5.85

a = 4.74

SD = [tex]\sqrt{\frac{(5.85-4.74)^{2} }{12} }[/tex]

SD = [tex]\sqrt{\frac{(1.11)^{2} }{12} }[/tex]

SD = 0.1026

Hence, the standard deviation is 0.1026

c) The probability that the child will be older than 5 years will be

p(older than 5) = 5.85 - 5 / 5.85 - 4.74

= 0.85 / 1.11

= 0.7657

Hence, the probability that the child will be older than 5 years old is 0.7657

d) The probability that the child will be between 4.84 and 5.34 years old will be

p(between 4.84 and 5.34) = 5.34 - 4.84 / 5.85 - 4.74

= 0.5 / 1.11

= 0.4504

Hence, the probability that the child's age is between 4.84 and 5.34 is  0.4504

e) If the child is at the 9th percentile, the age will be

At the 9th percentile = 4.74 + 9/100 ×(5.85 - 4.74)

= 4.74 +(0.9)(1.11)

= 4.74 + 0.999

= 5.739

Hence, at the 9th percentile, the age of the child is 5.739 years old.

When a point P(x, y) is rotated 270° counterclockwise around the origin, we flip x and y and reverse the sign of x.

Thus,

The rule to rotate a point P(x, y)  after a rotation 270° counterclockwise around the origin is:

P(x, y) → P'(y, -x)

From the Graph,

In our case, we have the points

T = (4, -8)

U = (6, -8)

V = (9, -3)

W = (7, -3)

Thus, the coordinates of the vertices after a rotation 270° counterclockwise around the origin will be:

P(x, y)          →        P'(y, -x)

T (4, -8)       →       T'(-8, -4)

Answer:

-22 1/3

Step-by-step explanation:

We should start by subtracting both sides of the equality by 21.

After doing this, we get that -67=3m.

Furthermore, we can divide both sides by 3 and get -67/3=m.

However, this is an improper fraction, not a mixed number.

If we divide -67 by 3, we get -22 1/3.

Therefore, m= -22 1/3

What is an experiment?

An experiment simply means a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. It should be noted that experiments provide insight into cause-and-effect as they demonstrate what outcome occurs when a particular factor is manipulated

Experiments have a vital place in the development of science because experiments are used to test the reality of a thought, an axiom, or a phenomenon with a theoretical basis and to turn it into a law or a theorem.

In this case, testing the new sneakers is an experiment.
