Let's first find out their factors.

90's factors are :

$1,2,3,5,6,9,10,15,18,30,45,90$

190's factors are :

$1,2,5,10,19,38,95,190$

The common factors of 90 and 190 are :

1,2,5 and 10.

The greatest one among these is, 10. So the greatest factor of 90 and 190 is 10.

Answer:

103

Step-by-step explanation:

x = 180-77 = 103

because it's a straight line, so 180 - 77 to find x

Consider the following pair of equations:

Sloan [31]

-2x+8 = x-1 substitute for one of the y

-8. -8 solve for x

-2x = x -9

+x =. +x

-1x = -9

/-1. =. /-1

x=9

y=-2(9)+8 now solve for y by putting x

y= 18 +8 in the one of the original

y= 26 equations.

Set A of six numbers has a standard deviation of 3 and set B of four numbers has a standard deviation of 5. Both sets of numbers

Alenkinab [10]

Given:

$\sigma_A=3$

$n_A=6$

$\sigma_B=5$

$n_B=4$

$\overline{x}_A=\overline{x}_B$

To find:

The variance. of combined set.

Solution:

Formula for variance is

$\sigma^2=\dfrac{\sum (x_i-\overline{x})^2}{n}$ ...(i)

Using (i), we get

$\sigma_A^2=\dfrac{\sum (x_i-\overline{x}_A)^2}{n_A}$

$(3)^2=\dfrac{\sum (x_i-\overline{x}_A)^2}{6}$

$9=\dfrac{\sum (x_i-\overline{x}_A)^2}{6}$

$54=\sum (x_i-\overline{x}_A)^2$

Similarly,

$\sigma_B^2=\dfrac{\sum (x_i-\overline{x}_B)^2}{n_B}$

$(5)^2=\dfrac{\sum (x_i-\overline{x}_B)^2}{4}$

$25=\dfrac{\sum (x_i-\overline{x}_B)^2}{4}$

$100=\sum (x_i-\overline{x}_B)^2$

Now, after combining both sets, we get

$\sigma^2=\dfrac{\sum (x_i-\overline{x}_A)^2+\sum (x_i-\overline{x}_B)^2}{n_A+n_B}$

$\sigma^2=\dfrac{54+100}{6+4}$

$\sigma^2=\dfrac{154}{10}$

$\sigma^2=15.4$

Therefore, the variance of combined set is 15.4.
