Choose all values of the correlation coefficient, r, that indicate a strong, but not perfect, linear association between two variables.
A r=-0.85
B. r=-0.10
C. r= 0.15
D. r=0.90
E r= 1.00
Answers
Answer:
D. r = 90
A. r = -0.85
Explaination:
• r = 1 is perfect and strong.
• So r = 90 is strong but not perfect.
• Same with -0.85, but as negative.
-0.85, and 0.90 indicate a strong relationship between the two variables but not a perfect linear association between the two variables option (A) and (D) are correct.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
We have a value of correlation coefficients.
We know when the correlation coefficient r is 1 then we can say the relation between two variables is perfect and strong.
When the value of correlation coefficients lies between 0.8 to 1 the relation between two variables is said to be strong.
Similarly when the value of correlation coefficients lies between -0.8 to -1 the relation between two variables is said to be strong.
For the r = -0.85, this indicates a strong relationship but is not perfect.
For the r = -0.10 this indicates a weak relationship but is not perfect.
For the r = 0.15 this indicates a weak relationship but is not perfect.
For the r = 0.90 this indicates a strong relationship but is not perfect.
For the r = 1 this indicates a strong relationship and perfect.
Thus, -0.85, and 0.90 indicate a strong relationship between the two variables but not a perfect linear association between the two variables option (A) and (D) are correct.

a teacher asks five students to write an equation with a solution of x= 4 . the students and their equations are shown below. which of the following students correctly wrote an equation with x= 4 as the solution ? select three that apply
Answers
Answer:
[tex](b)\ 2x - 9 = -1[/tex]
[tex](c)\ -2x + 12 = 4[/tex]
[tex](e)\ 2(x - 10) = -12[/tex]
Step-by-step explanation:
Required
Which equals [tex]x = 4[/tex]
[tex](a)\ 2x + 6 = 2[/tex]
Collect like terms
[tex]2x = 2 - 6[/tex]
[tex]2x = -4[/tex]
Divide both sides by 2
[tex]x = -2[/tex]
[tex](b)\ 2x - 9 = -1[/tex]
Collect like terms
[tex]2x = -1 + 9[/tex]
[tex]2x = 8[/tex]
Divide both sides by 2
[tex]x = 4[/tex]
[tex](c)\ -2x + 12 = 4[/tex]
Collect like terms
[tex]-2x =- 12 + 4[/tex]
[tex]-2x =-8[/tex]
Divide both sides by -2
[tex]x = 4[/tex]
[tex](d)\ 2(x + 2) = 10[/tex]
Divide both sides by 2
[tex]x + 2 =5[/tex]
Collect like terms
[tex]x = 5-2[/tex]
[tex]x = 3[/tex]
[tex](e)\ 2(x - 10) = -12[/tex]
Divide both sides by 2
[tex]x - 10 = -6[/tex]
Collect like terms
[tex]x = 10 - 6[/tex]
[tex]x = 4[/tex]
Hence, the equations with the required solution are:
[tex](b)\ 2x - 9 = -1[/tex]
[tex](c)\ -2x + 12 = 4[/tex]
[tex](e)\ 2(x - 10) = -12[/tex]
LOCKER NUMBERS What is the probability that a 6-digit locker combination with the digits 3, 5, 7, 3, 5, and 2 is the number 53-27-35?
A.1/90
B.1/180
C.1/720
D.1/360
Answers
I think because it’s 6 Digit accommodation
The probability that a 6-digit locker combination, will be 1/180. Then the correct option is B.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
The factor of n is given as the production of the number n, (n – 1), (n – 2)… and 1.
Then the factorial of n is given as
n! = n x (n – 1) x (n – 2) x … 3 x 2 x 1
A 6-digit locker that contains the digit will be 3, 5, 7, 3, 5, and 2.
Then the total number of combination without repetition will be given as,
Total events = 6! / (2! x 2!)
Total events = 6 x 5 x 4 x 3 x 2 x 1 / (2 x 1 x 2 x 1)
Total events = 6 x 5 x 3 x 2 x 1
Total events = 180
Then the favorable event will be
Favorable events = 1 {53-27-35]
Then the probability will be
P = (Favorable event) / (Total events)
P = 1/180
Then the correct option is B.

Calculate the area of the parallelogram.
Answers
Considering the provided information in the given question, we have :
Base of the parallelogram = 5.5 cmHeight of the parallelogram = 2.5 cmWe have to find the area of the parallelogram.
As we know that,
⇒ Area of parallelogram = Base × Height
Substituting the values,
⇒ Area of parallelogram = 5.5 cm × 2.5 cm
⇒ Area of parallelogram = 13.75 cm²
Therefore, area of the parallelogram is [tex] \bf 13.75 \: cm^2 [/tex]
Help with this equation please
Answers
Answer:
[tex]y=-\frac{2}{3}x+6[/tex]
Step-by-step explanation:
Let the equation of the line representing the given table is,
y = mx + b
Here, m = slope of the line
b = y-intercept
From the given table,
Since, slope of the line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Therefore, slope of the line passing through (3, 4) and (4, [tex]\frac{10}{3}[/tex]) will be,
m = [tex]\frac{4-\frac{10}{3} }{3-4}[/tex]
= [tex]\frac{\frac{12-10}{3}}{3-4}[/tex]
= [tex]-\frac{2}{3}[/tex]
Therefore, equation of the line will be,
[tex]y=-\frac{2}{3}x+b[/tex]
Since, this line passes through a point [tex](1, \frac{16}{3})[/tex],
By satisfying the equation with the given point,
[tex]\frac{16}{3}=-\frac{2}{3}(1)+b[/tex]
[tex]b=\frac{16}{3}+\frac{2}{3}[/tex]
[tex]b=\frac{18}{3}[/tex]
[tex]b=6[/tex]
Therefore, equation of the line will be,
[tex]y=-\frac{2}{3}x+6[/tex]
