There are a few ways to find this. You can use prime factorization to find the LCM or the GCF

The GCF = 77 so 77 will divide into 539 and 3465

Answer = 77

Statistics Question. Use the Desmos graphing calculator to find the least-squares regression line for the dataset in the table:

Soloha48 [4]

Given:

The table of values.

To find:

The least-squares regression line for the data set in the table by using the desmos graphing calculator.

Solution:

The general form of least-squares regression line is:

$\hat{y}=mx+b$ ...(i)

Where, m is the slope and b is the y-intercept.

By using the desmos graphing calculator, we get

$m\approx 2.55,b\approx -6.435$

Substitute these values in (i).

$\hat{y}=(2.55)x+(-6.435)$

$\hat{y}=2.55x-6.435$

Therefore, the correct option is A.

I'll take this challenge since I'm not feeling lazy for once.... x would represent Gavin and y would represent Seiji.

a. $x+y=425, x-y=25$

b. I will solve your system using substitution.
$x+y-425, x-y=25$
Step 1: Solve $x+y=425$ for x
$x+y+-y=425+-y$ (add -y for both sides)
$x=-y+425$
Step 2: substitute $-y+425$ for x in $x+b=25$
$x+y=25$
 $-y+425-y=25$
$-2y+425=25$ (simplify both sides of the equation)
$-2y+425+-425=25+-425$ (add -425 to both sides)
 $-2y=-400$
$\frac{-2y}{-2} = \frac{-400}{-2}$
y=200
step 3: substitute 200 for y in $x=-y+425$
$x=-y+425$
$x=-200+425
$
$x=225$
$x=225, y= 200$

c. Already answered with the picture that is attached.

d. Gavin earned 225 dollars while Seiji earned 200 dollars.
