Look at the following relation. What is the domain and range?

mylen [45]

Answer & Step-by-step explanation:

The domain is the input, and the range is the output.

The domain is also known as the x values and the output as the y values (x,y).

So:

domain: {4, -1, 0, 2}

range: {-4, 3, 5, 8}

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.

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

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

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

6. a. Ir.) : (x ) is a point on a line passing through (2.3) and (4.5) What is the range?

Fed [463]

This is a linear function which means that there is no restrictions on domain and range. The range is all real numbers.

Which expression means the same as "subtract 3 from 7 and then multiply

marishachu [46]

Answer:

A 4* (7 - 3)

Step-by-step explanation:

Let's do this part by part. First we have "subtract 3 from 7:" this means we are taking 3 out of 7.

7 - 3

Next we have "then multiply by 4." So we need to take the above quantity and multiply the whole thing by 4.

(7-3) x 4

4 * (7-3)

The answer is A.
