Answer:

No

Step-by-step explanation:

If the line did pass through that point, then plugging in the point to the equation would be true. But when you plug in 4 for x, the y would be 18, not 15.

Consider a uniform distribution created by a random number generator. The distribution looks like a square with a length of 1 an
vekshin1
The rigorous way to do this would be to compute a few integrals, but less work is usually better. Each of these probabilities correspond to the areas of rectangles. Each rectangle will have a height of 1, and the probability of interest will tell you everything you need to know about their lengths.

\mathbb P(0\le X\le0.4)\implies \text{length}=0.4\implies\mathbb P(0\le X\le0.4)=0.4\times1=0.4

\mathbb P(0.4\le X\le1)\implies \text{length}=0.6\implies\mathbb P(0\le X\le0.4)=0.6

Alternatively, you can use the fact that \mathbb P(0.4\le X\le 1)=1-\mathbb P(0\le X\le 0.4) to get the same result.

\mathbb P(X>0.6)=\mathbb P(0.60.6)=0.4

\mathbb P(X\le0.6)\implies \text{length}=0.6\implies\mathbb P(X\le0.6)=0.6

\mathbb P(0.23\le X\le0.76)\implies \text{length}=0.76-0.23=0.53\implies\mathbb P(0.23\le X\le0.76)=0.53

Rewrite y + 1 = -2x – 3 in standard form
Misha Larkins [42]

The algebraic expressions can be written as

a+b+c=0

The given expression is,

\begin{gathered} y+1=-2x-3 \\ -2x-y=1+3 \\ -2x-y=4 \\ -2x-y-4=0 \\ 2x+y+4=0 \end{gathered}
