Answer:

Y inter=4

Slope= -5/2

Step-by-step explanation:

First find the slope y1-y2/x1-x2

Find two points (0,4) and (2,-1) Subtract 4-(-1)/0-2

-5/2 The y intercept is 4 because thats where x is 0

So the the equation is y=-5/2x+4

Where -5/2 is slope and 4 is Y intercept

A cell phone tower covers a circular area with a radius of 15 miles. You are at a location that is 11 miles west and 12 miles so

Murljashka [212]

Answer:

No you do not.

This is because we can use Pythagoras Theorem to show that our location sits outside the 15 mile radius of the cell tower.

To work is out you would write the equation

${11}^{2} + {12}^{2} = 265$

Then to work out the Hypotheses you would

$\sqrt{265} = 16.2788205961$

Which proves that the location is outside of the 15 Mile radius of the cell tower.

A distribution is given as

Arada [10]

If X is uniformly distributed on the interval (0, 12), then its PDF is

$f_X(x) = \begin{cases}\frac1{12} & \text{if }0 < x < 12 \\ 0&\text{otherwise}\end{cases}$

or simply

$f_X(x) = \dfrac1{12} \text{ where } 0 < x < 12$

and the zero-elsewhere case is assumed.

Whether you include 0 and 12 in the domain is irrelevant, since the probability that X = 0 or X = 12 are both zero.
