Modular arithmetic<br> Pls a little explaine it

fredd [130]

Step-by-step explanation:

(72)¹⁴³ ≡ x (mod 7)

Since 72 ≡ 2 (mod 7),

72³ ≡ 2³ (mod 7) ≡ 1 (mod 7).

Therefore (72)¹⁴³ = (72³)⁴⁷ * (72²)

≡ 1⁴⁷ * 4 (mod 7) ≡ 4 (mod 7).

The answer is A.

Given the line of the best fit for a set of data points with equation y=-5x-2.5 what is the residual for the point (3,6)

HACTEHA [7]

Answer:

The residual of the point $(3,6)$ in the equation $y=-5(x)-2.5$ is $= 23.5$

Step-by-step explanation:

We have been given point $(3,6)$ where $x=3$ .

Now the equation is $y=-5(x)-2.5$ .

Plugging the value of $x=3$ in the equation of $y=-5(x)-2.5$ ,

we have to find the predicted value of y and $y=-5(3)-2.5 =-15-2.5=-17.5$ .

So y predicted $=-17.5$ .

To find the residual point we have to subtract the actual value from the predicted value.

As actual value of $y=6$ along with the points $(3,6)$ .

Residual point = Actual value - Predicted value.

$=6 -(-17.5) =23.5$

So the residual for the point $(3,6)$ is $23.5$ .
