What is the equation for the linear model in the scatter plot obtained by choosing the two points closest to the line?

HACTEHA [7]

Answer:

Option C is the answer.

Step-by-step explanation:

To find the equation of the straight line equation i.e, we must be given with the two points $\left (x_{1},y_{1} \right )$ and $\left (x_{2},y_{2}\right )$

Since from the graph the two points closest to the line are $\left ( 10,36 \right )$ and $\left ( 22,12 \right ).$

Equation of line with two points closest to the line :

$y-y_{1}=m\cdot \left ( x-x_{1} \right )$

where m is the slope.

First we find the slope(m)= $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$m=\frac{12-36}{22-10}$

on simplify we get, $m=-2$ .

Now, to find the equation of the line: $y-y_{1}=m\cdot \left ( x-x_{1} \right )$

$y-36=\left ( -2 \right )\cdot \left ( x-10 \right )$

Apply distributive property on right hand side, we get

$y-36=-2\cdot x+20$

Adding both sides by 36, we get

$y=-2x+20+36$

$y=-2x+56$ .

The equation for the linear model in the scatter plot obtained by the two closest point $\left ( 10,36 \right ) and \left ( 22,12 \right )$ closest to the line is,

$y=-2x+56$

Substitution method...need help.. started but cant finish

trapecia [35]

Solve either equation for either variable. Since the second one has y on its own, the easiest choice is to solve that for y.

-5x + y = 13 ⇒ y = 5x + 13

Now substitute this into the other equation to eliminate y and rewrite it entirely in terms of x :

-3x + 3y = 3 ⇒ -3x + 3 (5x + 13) = 3

Simplify and solve for x :

-3x + 15x + 39 = 3

12x = -36

x = -3

Substitute this into either original equation to solve for y. Plugging x = -3 into the first equation would give

-3 (-3) + 3y = 3

9 + 3y = 3

3y = -6

y = -2

So the solution to the system of equations is (x, y) = (-3, -2).

A certain composite number has 4 factors and the sum of them is 96. Find the number(hint the number is divisible by 7). Just don

ankoles [38]

Answer:

$\huge\boxed{77}$

Step-by-step explanation:

The number can be divisible by 7.

The multiples of 7 are 7,14,21,28,35,42,49,56,63,70,77,84 and so on

Finding the factors for all of the multiples of 7:

7 => 1,7 [Not 4 factors]

14 => 1,2,7,14 [4 factors but Sum = 24]

21 => 1,3,7,21 [4 factors but Sum = 32]

28 => 1, 2, 4, 7, 14, 28 [Not 4]

35 => 1,5,7,35 [4 factors but Sum = 48]

42 => 1, 2, 3, 6, 7, 14, 21, 42 [Not 4]

49 => 1,7,49 [Not 4]

56 => 1, 2, 4, 7, 8, 14, 28, 56 [Not 4]

63 => 1, 3, 7, 9, 21, 63 [Not 4]

70 => 1, 2, 5, 7, 10, 14, 35, 70 [Not 4]

77 => 1, 7, 11, 77 [4 factors and Sum = 96]
