Which of the following r-values represents the strongest correlation?
O A. -0.51
B. -0.61
C. -0.41
D. -0.71
Answers
Answer:
Step-by-step explanation:
-0.71
The r - value -0.71 represents the strongest correlation which is negative correlation.
What is the correlation coefficient?The correlation coefficient is a quantitative method of calculating correlation. It is a statistical concept, which helps in establishing a relation between predicted and actual values obtained in a statistical experiment.
For the given situation,
The options has the r - values, we need to check which option represents the strong correlation.
Now., The relationship between two variables is generally considered strong when their r value is larger than 0.7.
A correlation of r = -0.71 suggests a strong, negative association between two variables.
A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.
Hence, we can conclude that the r - value option (D) -0.71 represents the strongest correlation which is negative correlation.

The perimeter of PRST is 10 more than 5(RS). If PR=26, find RS.
Answers
Answer:
RS = 14
Step-by-step explanation:
Perimeter = 26 + 26 + PT + RS
We know that PT and RS are equal to each other so I changed the equation to 26 + 26 + x + x = 10 + 5x and then I got x by itself and the integer on one side 42 = 3x, so 14 = x
The value of RS will be 14 for the given parallelogram.
What is a parallelogram?A basic quadrilateral with two sets of parallel sides is known as a parallelogram.
A parallelogram's facing or opposing sides are of equal length, and its opposing angles are of similar size.
There are 4 types of parallelograms, including 3 special types. The four types are parallelograms, squares, rectangles, and rhombuses.
Given the parallelogram where TS ║ PR and both are equal
Line TP ║ SR so it means TP = SR
Let's say
TP = SR = x
Now,
The perimeter of a parallelogram is 10 more than 5(RS)
So,
PT + TS + SR + RP = 5(RS) + 10
Now since TP = RS = x
So,
x + TS + x + RP = 5x + 10
5x - 2x = TS + RP - 10
x = (TS + RP - 10)/3
Now,
TS = RP = 26
So,
x = (26 + 26 - 10 )/3
x = 42/3
x = 14
Hence "The value of RS will be 14 for the given parallelogram".

Answer:
1. 35
2. 145
3. 55
4. 90
5. 145
Step-by-step explanation:
1. 35: angle 1 and 2 are a linear pair (meaning it is in one line and adds to 180). Since we know angle 2 is 145, ∠1 = 180 - 145
∠1 = 35
2. 145: ∠7 = ∠2 because they are alternate angles and alternate angles are equal
3. 55: ∠7 = ∠5 + ∠4 because vertically opposite angles are equal. We know that ∠5 = 90, hence ∠4 would equal 145 - 90 = 55
4. ∠5 = 90. It is given
5. 145: ∠9 = ∠2 because they are vertically opposite
Laurie earns $7.50 per hour at the fruit stand plus an extra $2.00 per hour on Sundays. One week in August, she worked on Sunday, Monday, and Wednesday. She worked the same number of hours on Monday and on Wednesday. On Sunday she worked 4 hours. If she earned a total of $83.00 for the week, how many hours did Laurie work on Monday? Enter and solve an equation.
Answers
Answer:
Hi there!
Your answer is:
She worked for 3 Hours on Monday.
Step-by-step explanation:
7.5$ per hour
7.5+2$ per hour on Sundays.
In August:
Sunday, Monday, Wednesday.
# of hours for Monday =Wednesday
Sunday= 4 hrs (which would mean 9.5$ * 4)
Monday and Wednesday will be modeled by X
X + 38$ (earned sunday)= 83$
-38
X= 45$
Since X represents BOTH monday and wednesday, divide by 2
45/2 = 22.5$
CHECK YOUR WORK
22.5$ (monday) + 22.5$ (wednesday) + 38$ (sunday)= 83???
45=38=83???
83=83 YES
Now, to determine how many hours that is, we divide the earned wages by the wage per hour.
22.5 / 7.5 = 3 HOURS
CHECK YOUR WORK
3 hours * 7.5 per hour = 22.5???
22.5 = 22.5 YES
Hope this helps
If she worked the same number of hours on Monday and on Wednesday. On Sunday she worked 4 hours. If she earned a total of $83.00 for the week, the number of hours that Laurie work on Monday will be: 3 hours
$7.5= 1 hour Other days
$9.50 or ($7.50+$2.00) = 1 hour Sunday
Let Sunday= 4×$9.50 =$38
Let Monday= x × $7.5=$7.5x
Let Wednesday= x × $7.5=$7.5x
Let Total earning=$83
Let x represent the number of hours
Hence:
First step is to formulate
7.5x+7.5x+38=83
Second step is to calculate how many hours did Laurie work on Monday
x =83-38÷ 7.5+7.5
x=83-38÷15
x=45÷15
x=3 hours
Inconclusion If she worked the same number of hours on Monday and on Wednesday. On Sunday she worked 4 hours. If she earned a total of $83.00 for the week, the number of hours that Laurie work on Monday will be: 3 hours
