The length of OX would be 6.5 units.

If you look at the angle, it is bisected equally - meaning the ray separating it is a bisector. (The two triangles are similar by angle-angle similarity.) Since the line is a bisector, you simply divide 13 by 2 to get 6.5.

OX = 6.5

13=DX,

OX = 0.5*DX

13*0.5=6.5

It’s linear so you map out the first differences and then put it into y=Mx+b form. For the you gotta find the y intercept

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

Let's find the slope (m) :

$\dfrac{y2 - y1}{x2 - x1}$

$\dfrac{16 - 11}{9 - 6}$

$\dfrac{5}{3}$

slope of given line is 5/3

now, let's plug the value of coordinates of a point lying on the line ( for example : (6 , 11) and slope (m) to find the y - intercept (c) :

$y = mx + c$

$11 = \bigg(\dfrac{5}{ 3} \times 6 \bigg) + c$

$11 = (5 \times 2) + c$

$11 = 10 + c$

$c = 11 - 10$

$c = 1$

value of y - intercept (c) = 1, so our equation will be :

$y = mx + c$

$y = \dfrac{5}{3}x + 1$

40 centimetres to inches

Agata [3.3K]

Answer: 40 centimeters is 15.748 inches.

Step-by-step explanation:

To start things off, a centimeter is equal to about 39.37 inches. If you want to know how to multiply a centimeter to get an inch, just multiply the quanity in centimeter by 0.39370078740157 or into smaller terms, 39.37. By doing so, you will get the answer, 15.748 inches by multiplying by centimeters.

You previously found the mean of this data set. Use that in answering the question. 63, 89, 92, 73, 79, 72, 34, 36, 94, 21, 25,

Answer:

Sum of squares of differences = 11239.74

Step-by-step explanation:

We are given the following data set:

63, 89, 92, 73, 79, 72, 34, 36, 94, 21, 25, 93, 22, 90, 79

We have to calculate the sum of square of the data set.

Formula:

$\text{Sum of square of differences} = \sum (x_i -\bar{x})^2$

where $x_i$ are data points, $\bar{x}$ is the mean and n is the number of observations.

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

$Mean =\displaystyle\frac{962}{15} = 64.13$

Sum of squares of differences =

1.284444444 + 618.3511113 + 776.5511113 + 78.61777778 + 221.0177779 + 61.88444445 + 908.0177776 + 791.4844443 + 892.017778 + 1860.484444 + 1531.417778 + 833.2844446 + 1775.217777 + 669.0844446 + 221.0177779

= 11239.74
