g If there is a very weak correlation between two variables, then the coefficient of determination must be

Answers

Answer 1

Answer:

very close to or equal to zero

Explanation:

Correlation coefficients refer to the degree of relationship between two exclusive variables.

A weak correlation means that a change in one variable does not significantly affect or cause any reaction with the second variable.

For example, if the prices of coffee and the price of ballons are observed in the same period and found to have a correlation of +0.00006. This means that there is little or no correlation, or relationship, between the two variables. Weak relationships are usually between -0.1 and +0.1

Correlation coefficients can also be positive or negative.

It is positive if both factors seem to move in the same direction. As an example, if the price of stocks for Apple and Microsoft change in the same direction in the same period, they are said to have a positive correlation coefficient.

On the flip side, the correlation coefficient will be negative if the price of one stock moves upwards whilst the other moves downwards. A perfect negative relationship would read -1.

None of the other answers are correct

Answers

Answer:

4

Step-by-step explanation:

AB + BC = AC

(x + 4) + (2x - 10) = 2x + 1

x + 4 + 2x - 10 = 2x + 1

x - 6 = 1

x = 7

BC = 2(7) - 10 = 4

A sample survey was taken of 100 students to determine which of three homecoming themes students prefer. The percentages of students
selecting themes A and B are shown in the table.
Theme A (96)
Theme B (%)
25
45
If the remaining students selected theme C, which statistical model could be used to make predictions about the theme a random student might
prefer?
O A 5 white marbles, 6 yellow marbles, and 9 green marbles
OB. 5 white marbles, 6 yellow marbles, and 8 green marbles
OC 4 white marbles, 6 yellow marbles, and 9 green marbles
OD 4 white marbles, 6 yellow marbles, and 8 green marbles

Answers

Following the same proportions as the table, the correct option is:

A. 5 white marbles, 6 yellow marbles and 11 green marbles.

---------------------------------------

From the table, we have that:

25% of the students prefer Theme A(white).45% of the students prefer Theme B(green).The rest, that is, 100 - (25 + 45) = 100 - 70 = 30% of the students prefer Theme C(yellow).

---------------------------------------

For the marbles, we have to find an option in which the proportions are the same, that is: 25% white, 45% green, 30% yellow.

---------------------------------------

Option A:

Out of 20, 5 white, 6 yellow and 11 green.

[tex]\frac{5}{20} = 0.25, \frac{6}{20} = 0.3, \frac{11}{20} = 0.55[/tex]

Same proportions, thus, option A is correct.

A. 5 white marbles, 6 yellow marbles and 11 green marbles.

Answer:

A.  5 white marbles, 6 yellow marbles, and 9 green marbles

Step-by-step explanation:

What is Ratio?

A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.

Given:

We know Equivalent ratios are those ratios when two or more fraction on simplification gave the same value.

So, the find the equivalent ratio to given ratio can be achieved by multiplying or dividing the same number to Numerator and Denominator of the fraction.

Thus, Marta should have plotted the ordered pairs that were given and then, starting with the last point, moved up 3 and right 2 to find each next point.

let the short story have x pages

so that the novel's pages will be 14x

the combined pages for novel and short story is =390 pages

Required

the individual number of pages

14x+x=390

15x=390

divide both sides by 15

x=26

the short story have 26 pages

the novel's pages will be 14(26)= 364

Write the equation of the line, in slope-intercept form, that passes through (3,-1) and has a slope = -2/3

Answers

Answer:

The equation of the line, in slope-intercept form, that passes through (3,-1) and has a slope = -2/3 is:

[tex]\mathbf{y=-\frac{2}{3}x+1}[/tex]

Step-by-step explanation:

We need to write equation of the line, in slope-intercept form, that passes through (3,-1) and has a slope = -2/3.

The equation for slope-intercept form is: [tex]y=mx+b[/tex]

where m is slope and b is y-intercept.

We are given slope m = -2/3 and we need to find y-intercept i.e b to write equation of line.

Using point (3,-1) and slope m=-2/3 we can find y-intercept i.e b

[tex]y=mx+b\\-1=-\frac{2}{3}(3)+b\\-1=-2+b\\b=-1+2\\b=1[/tex]

So, y-intercept b = 1

The equation of the line, in slope-intercept form, that passes through (3,-1) and has a slope = -2/3 is:

[tex]y=mx+b\\\mathbf{y=-\frac{2}{3}x+1}[/tex]
