Formula for slope: $\frac{y2-y1}{x2-x1}$
Plug in points given: $\frac{136-27}{13-2} 
= \frac{109}{11} = 9.9 = 9 \frac{9}{10} (Rounded) 
$
Slope: $9.9 = 9 \frac{9}{10}$

Answer:

9.9 is the slope of the trend line drawn into the scatter plot

Step-by-step explanation:

Using slope formula:

$\text{Slope} =\frac{y_2-y_1}{x_2-x_1}$ ....[1]

As per the statement:

Consider two points from the given graph:

$(2, 27)$ and (13, 136)

Substitute in [1] we have;

$\text{Slope} =\frac{136-27}{13-2}$

⇒ $\text{Slope} =\frac{109}{11}$

Simplify:

$\text{Slope} \approx 9.9$

Therefore, 9.9 is the slope of the trend line drawn into the scatter plot

Question Is In The Picture

Answer:

Step-by-step explanation:

Pythagorean theorem states that a^2 + b^2 = c^2

this theorem only works on triangles with an angle of 90 degrees or a right triangle.

18^2 + 24^2 = 900

the square root of 900 is 30

I did the square root of 900 because the square root is the 'opposite' of squaring which is what you need to do in order to find 'c' is the Pythagorean theorem. 'a' is 18, and 'b' is 24

Answer is 30

Hello! My name is Galaxy and I will be helping you today, I hope you are having a nice day!

We can solve this in two steps, Comprehension and Solving. I'll go ahead and start with Comprehension.

If you have any questions feel free to ask away!!

Comprehension

We know according to the laws of geometry that all angles in a triangle add up to 180 degrees.

We also know that in an isosceles angle, the base angles are equation to each other.

Now that we know what we need to know, we can setup an equation.

$2x-6+(2x)=180$

We can do this because first of all, we know that 2x-6 is one of the angles and as per the base angles of an isosceles triangle we know that both base angles are x, therefore we can add 2x to get 180 degrees.

I'll start solving now.

Solving

We can solve this by using the equation we made above and solving it with algebra.

$2x-6+2x=180\\4x-6=180\\4x=186\\x=46.5$

We know that x is equal to 46.5 degrees. We can check that by inputting it into the equation.

$2(46.5)-6+2(46.5)=180?\\4(46.5)=186?\\46.5=46.5$

We've proven that our answer is correct by double checking,

Therefore the answer is 46.5!

Cheers!

The length of a rectangle is twice the width. the perimeter is 32 cm more than the width. find the dimensions of the rectangle.

SCORPION-xisa [38]

Width: x
Length: 2x
Perimeter=2x+2x+x+x=6x
32 cm more than width means x+32
6x=x+32
5x=32
x=6.4
Dimension is 6.4×12.8 (width×length)
