Answer:
The first graph (topmost graph)
Step-by-step explanation:
Correlation coefficient of -1: Negative correlation
As variable x (horizontal axis) increases, variable y (vertical axis) should decrease.
Hence, gradient of the graph is negative, sloping downwards as x increases.
Graph 2 is eliminated (positive correlation approximately 1)
Graph 4 is also wrong as there is simply no correlation. (Points are random with no fixed pattern or trend)
Graphs 1 and 3 show negative correlation.
However, for graph 3, several points are not accurate, leading to a straight line not being drawn accurately. (Slightly off) . Correlation of this graph is negative but not closest to -1.
Hence, the first graph is the closest to -1 in terms of correlation coefficient.

sin a° = 3/√13, cos a° = 2/√13 and tan a° = 3/2 as per the rules of a trigonometric ratio.
What are trigonometric ratios?Trigonometric ratios are developed based on the right-angled triangle.
The largest side length of a right-angled triangle is called hypotenuse.
Suppose an angle Ф is in between the hypotenuse and base of a triangle. The base is called the adjacent side.
The remaining side length is called the opposite side length.
sinФ = opposite side length/ hypotenuse
cosФ = adjacent side length /hypotenuse
tanФ = opposite side length/adjacent side length
What is the trigonometric ratio given in the above table?According to the figure, a right-angled triangle has hypotenuse 3√13, angle a is in between hypotenuse and base of the triangle.
The length of adjacent side to the angle a° is 6 units and opposite side has a length 9 units.
now, according to the trigonometric ratio
sin a° opposite side /hypotenuse = 9 /3√13 = 3/√13
cos a° = adjacent side / hypotenuse = 6/3√13 = 2/√13
tan a° = opposite side/adjacent side = 9/6 = 3/2

Madison and her brother drove around the perimeter of their neighborhood looking for their cat. The diagram above shows the path they drove. In total, 56 kilometers did they drive. This can be solved using the concept of rectangular perimeter.
What is perimeter of a rectangle?The circumference of a form is known as its perimeter. One must sum the lengths of the all four edges of a rectangular or squares to determine its perimeter. In this instance, the rectangle's length is represented by x and its width by y. P = 2 (x+y), which is the perimeter.
The diagram is actually looks like a rectangle.
Here the length becomes = 10 km
and breadth = 18 km
The question mark here is: 18 -10 = 8km
so, perimeter = 2 (length + breadth)

What explains the above-mentioned resolution?A shape's surface area is measured by its area.By multiplying the length and breadth of a rectangle or square, you can get its area.Area A is equal to x times y.
Square measurements, such as square inches, square feet, or square meters, are used to describe area.Multiplying a rectangle's length and breadth will reveal its area.A is the area, L is the length, W is the width, and * denotes multiply in the formula.
Area of the darkened area is equal to the sector's area minus the triangle's area.This is displayed as:π r² (∅/360) - 1/2 x b x h

If Shannon attempts 400 throws this year, the number of free throws that she would make is 100 free throws.
How to find the number of free throws?To find the number of free throws that Shannon might be able to make this year, you need to look at the rate at which she is able to make free throws from the number of throws that she makes.
When Shannon made 20 throws, she was able to make 5 free throws out of these 20 throws. This means that her rate of free throws is :
= Number of throws made / Total throws taken x 100 %
= 5 / 20 x 100 %
= 0. 25 x 100 %
= 25 %

Answer:
-8b^2 + 4b
Step-by-step explanation:
To simplify the expression (-6b^2 2b-1) + (-2b^2 + 4b), we need to combine like terms.
First, let's distribute the negative sign to the terms inside the first set of parentheses:
(-6b^2) + (-2b^1) = -6b^2 - 2b^1
Now let's combine the terms inside the second set of parentheses:
(-2b^2) + (4b) = -2b^2 + 4b
Finally, let's add the two expressions:
(-6b^2 - 2b^1) + (-2b^2 + 4b) = -6b^2 - 2b^1 - 2b^2 + 4b
Simplifying, we get:
-8b^2 + 4b = -8b^2 + 4b
The final simplified expression is: -8b^2 + 4b.

How long would it take to have 733,500 baht if your principal amount was 450,000 baht with a 9% interest rate?
Step-by-step explanation:
Time (in years) = (733,500 baht - 450,000 baht) / (450,000 baht * 9%)
Plugging in the values, we get:
Time (in years) = (733,500 baht - 450,000 baht) / (450,000 baht * 0.09)
Time (in years) = (283,500 baht) / (40,500 baht)
