Which of the following r-values represents the strongest correlation?
O A. -0.51
B. -0.61
C. -0.41
D. -0.71
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.

Justin is buying a cell phone that had a wholesale price of
$495. The cell phone was marked up 25%.
What is the selling price of the cell phone?
Answer:
$371.25
Step-by-step explanation:
If you want to take away 25%, you would need to find out how much 75% of the current price is. IF you think about it, 75% of the $495 is 25% of 100% of it taken away.
So
0.75 x 495 = 371.25

Answer:
-143
Step-by-step explanation:
We have to substitute 4 into x.
g(4) = -3(4)^2 + 2(4) - 7
g(4) = -12^2 + 8 - 7
g(4) = -12^2 + 1

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 $83.00 for the week, how many hours did Laurie work on Monday? Enter and solve an equation.
Answer:
Hi there!
Your answer is:
She worked for 3 Hours on Monday.
Step-by-step explanation:
7.5$ 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

Can someone please help me with this problem
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

Choose an equation that would be used to solve
0 = -x2 + 10X-8
(x + 25)2 = -8
O(x - 5)2 = 17
(x - 10)2 = 25
Answer:
(x - 5)² = 17
Step-by-step explanation:
Given
0 = - x² + 10x - 8 ( multiply through by - 1 to clear the leading negative )
x² - 10x + 8 = 0 ( subtract 8 from both sides )
x² - 10x = - 8
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 5)x + 25 = - 8 + 25
(x - 5)² = 17
The perimeter of PRST is 10 more than 5(RS). If PR=26, find RS.
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".

Find the value of (4/25)^-1/2
The value of the given exponent is [tex]\frac{5}{2}[/tex]
Given:
The exponent = [tex](\frac{4}{25})^{\frac{-1}{2}}[/tex]
To find:
The value of a given exponent
Solution:
[tex](\frac{4}{25})^{\frac{-1}{2}} = ?[/tex]
Using the identity of an exponent : [tex](\frac{m}{n})^{x} = \frac{m^{x}}{n^{x}}[/tex]
[tex](\frac{4}{25})^{\frac{-1}{2}} = \frac{(4)^{(\frac{-1}{2})}}{(25)^{(\frac{-1}{2})}}\\[/tex]
Using the identity of an exponent : [tex]a^{-x} = \frac{1}{a^x}[/tex]
[tex]=\frac{(25)^{(\frac{1}{2})}}{(4)^{(\frac{1}{2})}}\\=\frac{(25)^{(\frac{1}{2})}}{(4)^{(\frac{1}{2})}}\\=\frac{((5)^2)^{(\frac{1}{2})}}{((2)^2)^{(\frac{1}{2})}}\\[/tex]
Using the identity of an exponent: [tex](a^{n})^m=a^{m\times n}[/tex]
[tex]=\frac{5^{(2\times \frac{1}{2})}}{2^{(2\times \frac{1}{2})}}\\=\frac{5^1}{2^1}\\=\frac{5}{2}[/tex]
The value of the given exponent is [tex]\frac{5}{2}[/tex].

Answer:
The two bowling alleys cost the same when there are 10 people in the group.
Step-by-step explanation:
Bustlin' Bowling first:
$35 base price and then $2 for each person. You can model that with b = 35 + 2x where b is the price and x is the guest number.
Grand Entertainment next:
$20 base price and then $3.50 for each person. You can model that with g = 20 + 3.5x where g is the price and x is the guest number.
So the question asks for the number of people (or what's x) that makes the cost of both bowling places equal.
In variables, it's asking when b = g, what is x?
Starting with b = g, we can replace those with the actual equations. If b = 35 + 2x and g = 20 + 3.5x, then b = g is the same as 35 + 2x = 20 + 3.5x.
I think you know how to solve that (because the trickiest part is usually translating the words into a solvable equation) but in case you don't, here's how:
35 + 2x = 20 + 3.5x
Subtract 2x from both sides.
35 = 20 + 3.5x - 2x
35 = 20 + 1.5x
Subtract 20 from both sides.
35 - 20 = 1.5x
15 = 1.5x
Divide both sides by 1.5.
15/1.5 = 1.5x/1.5
10 = x
Sooo, the answer is 10 people.
