Answer:
- 0.964
Step-by-step explanation:
Given that Coefficient of determination (R^2) = 0.93
Slope of regression line = - 5.26
The linear correlation Coefficient =?
The Coefficient of determination (R^2) is used to obtain the proportion of explained variance of the regression line. It is the square of the linear correlation Coefficient (R).
Hence. To obtain the linear correlation Coefficient (R) from the Coefficient of determination (R^2); we take the square root of R^2
Therefore,
R = √R^2
R = √0.93
R = 0.9643650
R = 0.964
However, since the value of the slope is negative, this depicts a negative relationship between the variables, hence R will also be negative ;
Therefore, R = - 0.964
The linear correlation coefficient of the data is: -0.96
Recall:
Coefficient of determination = R²R represents the linear correlation coefficient.A negative slope of regression line suggests relationship between variables will be negative, hence linear correlation coefficient will be negative.Thus, given:
Coefficient of determination of a set of data points = 0.93
Slope of the regression line = -5.26
Therefore:
R² = 0.93
R = √0.93
R = 0.96
Since the slope the regression line is negative, R will be negative in this case.
Therefore, the linear correlation coefficient of the data is: -0.96Learn more about linear correlation coefficient on:

Answer:
The m<PML + m<PMQ + m<QMN = 180° since they are supplementary
therefore,
45°+(6x-5)+x=180°
45+7x-5=180
40+7x=180
7x=140
x=20
To test it we should plug in x for each equation and the sum of those answers should equal 180
45+(6x20-5)+20=180?
45+115+20=180?
160+20=180?

If peter gets 80% correct, how many questions did peter MISS!
(Whoever answers can you please give me a clear explanation?)
Answer:
Peter missed five questions.
Step-by-step explanation:
Since the test has twenty-five questions, and Peter got 80% correct...
80/100 = __/25 <--What number is the numerator?
Well, to get from 100 to 25, you have to divide by 4. 100/4 = 25.
Now, what is 80/4? If you do the math, you should get 20.

11+x+13=40
Challenge of the day
Answer:
11+x+13=40
Step 1: Simplify both sides of the equation.
11+x+13=40
(x)+(11+13)=40(Combine Like Terms)
x+24=40
x+24=40
Step 2: Subtract 24 from both sides.
x+24−24=40−24
x=16
Answer:
x = 16
Step-by-step explanation:
11 + x + 13 = 40
x + 24 = 40
x = 40 - 24
x = 16
Thus, The value of x is 16

mm, the number of marbles per pack?
Answer:
D) 6(4 1/2 m + 2/3)=629Step-by-step explanation:
A display has 6 packs of marbles with a total mass of 629g. The packaging of each pack has a mass of 2/3 g and each marble has a mass of 4 1/2 g.
Which equation can we use to determine m, the number of marbles per pack?
A 6*4 1/2 m+ 2/3=629 B 6 m(4 1/2+ 2/3)=629 C 6 m+4 1/2+ 2/3=629 D 6(4 1/2 m + 2/3)=629================================
A total mass is the sum of 6 packs and each pack is:
m marbles + packaging = 4 1/2 m + 2/3We can put it as equation:
6(4 1/2m + 2/3) = 629Correct option is D

Answer:
There you are, hope this helps.
The required graph of the equation has been shown,
To draw the graph of the given equaiton,
1. y = 2x - 3 2. y = -2x + 3 3. y = 2x + 3 4. y = -2x - 3
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
1. y = 2x - 3
The slope is m = 2 and has a negative y-intercept of -3
2. y = -2x + 3
The slope is m = -2 and has a y-intercept of 3
3. y = 2x + 3
The slope is m = 2 and has a y-intercept of 3
4. y = -2x - 3
The slope is m = -2 and has a y-intercept of -3
Thus, the required graph of the equation has been shown,

Given two objects represented by the tuples (22, 1, 42, 10) and (20, 0, 36, 8):(a)Compute the Euclidean distance between the two objects. (b) Compute the Manhattan distance between the two objects.
Answer:
(a) 6.708
(b) 11
Step-by-step explanation:
Tuples ( 22, 1, 42, 10) and (20, 0, 36, 8)
Euclidian distance formula
[tex]D = \sqrt{(q1 -p1)^2 + (q2-p1)^2 + (q3 - p3)^2 + (q4 -p4)^2}[/tex]
D = [tex]\sqrt{(22-20)^2 + (1-0)^2 + (42 -36)^2 + (10 -8)^2 }[/tex]
= [tex]\sqrt{(2)^2 + (1)^2 + (6)^2 + (2)^2}[/tex]
= [tex]\sqrt{4 + 1 + 36 + 4 }[/tex]
= [tex]\sqrt{45}[/tex]
D = 6.708
Therefore the Euclidean distance between the tuples is 6.708
Manhattan Distance formula
D = |q1-p1| + |q2 -p2| + |q3 -p3| + |q4-p4|
= |22-20| + | 1-0| + | 42 -36| + | 10-8|
= |2| + |1| + |6| + |2|
D = 11
Therefore the Manhattan distance is equal to 11

A football field is 300ft long a sloth moving very quickly travels 60ft every 5 minutes based on this ratio how many minutes would it take a sloth to travel the length of a football field
Answer:
25 minute
Step-by-step explanation:
Speed is the ratio of the total distance traveled to the total time taken to reach this distance. The formula for speed is:
Speed = total distance / total time taken
The total distance covered by the sloth = 60 ft, and the time taken = 5 minutes, hence:
Speed = total distance / total time taken
speed of the sloth = 60 ft / 5 minutes = 12 ft per minute.
We can calculate the time taken for the sloth to travel the length of the football field (i.e. 300 ft)
speed = distance / time
12 ft/minute = 300 ft / time
time = 300 ft / (12 ft/minute)
time = 25 minute
