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.

Solve the following proportions, while using cross multiplication.
The sequence -9,-15,-21,-27 is a
Arithmetic sequence or Geometric sequence
Answer:
Arithmetic sequence
Step-by-step explanation:
It's Arithmetic sequence, because it's basically the list of integers that can be added, or subtracted by a same number every time. So, according to the following sequence shown, it shows that it's subtracting by [tex]6[/tex] every time.
Find cosα given that sinα = 5/13 and α is in quadrant II
Answer:
cos α = - [tex]\frac{12}{13}[/tex]
Step-by-step explanation:
Since α is in second quadrant then cosα < 0
Using the identity
sin²α + cos²α = 1 then
cosα = - [tex]\sqrt{1-sin^2\alpha }[/tex]
= - [tex]\sqrt{1-(\frac{5}{13})^2 }[/tex]
= - [tex]\sqrt{1-\frac{25}{169} }[/tex]
= - [tex]\sqrt{\frac{144}{169} }[/tex]
= - [tex]\frac{12}{13}[/tex]

I have sent a photo im not sure if u can see it
Answer:
That would be (-5,5)
Step-by-step explanation:
Unless I saw the photo wrong, you start at the coordinates (-3,-1). You move left 2 units to get to (-5,-1). Then you move 6 units up. That will get you to (-5,5).

12
28
-12
-28
Answer:
28
Step-by-step explanation:
(-1)(-7)(4)
Let’s rephrase this
(-1) * (-7) * 4
Multiple in order
(-1) * (-7) = 7
A negative times a negative equals a positive.
7 * 4= 28

Answer: the pre image is FGH
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
The triangle was translated 4 units down.
It can not be A, because it would have needed to be translated up 4 units.
It can't be C, because they are not both images, one is the starting image or the pre-image and the other is after the translation or the image.
D is incorrect because it con be determined.
Hope this helps :-)

Brainliest goes to the first CORRECT answer Thanks
Answer:
Step-by-step explanation:
This is a proportion question. You can take either of the other sides besides N to calculate the ratio. You need to use corresponding sides.
Here is the proportion
N/5 = 18/8
Multiply both sides by 5
N = 5 * 18/8
N = 90/8
N = 11.25
Find the equation of the linear function represented by the table below in slope-
intercept form.
y=Mx+B
Answer:
y = x + 4
Step-by-step explanation:
Let the equation of the linear function represented by the table is,
[tex]y-y_1=m(x-x_1)[/tex]
where m = slope of the line
And this line passes through the points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Slope of the given line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
From the given table two points lying on the function are (-4, 0) and (1, 5).
Slope 'm' = [tex]\frac{5-0}{1+4}[/tex] = 1
Therefore, equation of the linear function passing through (1, 5) and slope 1 will be,
y - 5 = (x - 1)
y = x + 5 - 1
y = x + 4
Find the area. Simplify your answer.
Answer: 1.5x²
Step-by-step explanation:
Rule: To find the area of a triangle, multiply the base times one side, then divide the product by 2.
Step 1: Find the length of the left side using the pythagorean theorem.
a^2 + b^2 = c^2.
x^2 + 2x^2 = 3x^2
√3x² = 3x
Step 2: Multiply the base times the hypotenuse.
x * 3x = 3x²
Step 3: Divide by two
3x²/2 = 1.5x²

Which expression is equivalent to -0.55 – 0.47a + a?
0.53a
0.55
0 -0.02a
Submit Answer
1.02 + a
0 -2.02a
O Type here to search
OBI
Answer:
-0.55 + 0.53a
Step-by-step explanation:
-0.55 – 0.47a + a
To find an expression equivalent to this, we must simplify the equation to a reasonable extent;
-0.55 – 0.47a + a
= -0.55 + 0.53a
= 0.53a - 0.55
The expression equivalent to the given one is -0.55 + 0.53a or 0.53a - 0.55
An isosceles triangle has two sides of equal length, a, and a base, b. The perimeter of the triangle is 15.7 inches, so the equation to solve is 2a + b = 15.7.
If we recall that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side, which lengths make sense for possible values of b?
