Let's prove each one:
A) y=x-3
x=0→y=0-3→y=-3=-3 ok
x=2→y=2-3→y=-1 different to 5 No

B) y=x+3
x=0→y=0+3→y=3 different to -3 No

C) y=4x-3
x=0→y=4(0)-3=0-3→y=-3=-3 ok
x=2→y=4(2)-3=8-3→y=5=5 ok
x=3→y=4(3)-3=12-3→y=9=9 ok
x=4→y=4(4)-3=16-3→y=13=13 ok

D) y=4x+3
x=0→y=4(0)+3=0+3→y=3 different to -3 No

Answer: Option C) y=4x-3

2.  Find the square root to find the accurate length of the hypotenuse.

distance formula:

1. The distance formula is used to determine the distance, d, between two points.

distance = speed × time

Formula- d= √x2-x1)²+(y2-y1)²

2. It's used for :

The amount of kerosene, in thousands of liters, in a tank at the beginning of any day is a random amount Y from which a random a
Tems11 [23]

Find the marginal density for Y by integrating the joint PDF over all possible values of x:

f_Y(y)=\displaystyle\int_{-\infty}^\infty f_{X,Y}(x,y)\,\mathrm dx=\int_0^y2\,\mathrm dx

\implies f_Y(y)=\begin{cases}2y&\text{for }0

Then the density of X conditioned on Y is

f_{X|Y}(x\mid y)=\dfrac{f_{X,Y}(x,y)}{f_Y(y)}=\frac1y

for 0 and undefined elsewhere.

Thus

P(0.25
