What is the domain of f(x) = 1/x
Kipish [7]

Answer:

(-∞,0)∪(0,∞)

Step-by-step explanation:

So we know that the domain is whatever X can be. We can do that by graphing the function. When we graph the function, you see that there is always an X value except at 1 point. That one point happens to be when x=0, and when x=0, the function also happens to be undefined (no number can be divided by 0). That is why the graph looks so weird. So, the answer would be

(-infinty,0) U (0, infinity)

SAT scores are normally distributed with a mean of 1,500 and a standard deviation of 300. An administrator at a college is inter
Rama09 [41]

Answer:

The administrator should sample 968 students.

Step-by-step explanation:

We have to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1 - 0.88}{2} = 0.06

Now, we have to find z in the Z-table as such z has a p-value of 1 - \alpha.

That is z with a p-value of 1 - 0.06 = 0.94, so Z = 1.555.

Now, find the margin of error M as such

M = z\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

Standard deviation of 300.

This means that n = 300

If the administrator would like to limit the margin of error of the 88% confidence interval to 15 points, how many students should the administrator sample?

This is n for which M = 15. So

M = z\frac{\sigma}{\sqrt{n}}

15 = 1.555\frac{300}{\sqrt{n}}

15\sqrt{n} = 300*1.555

Dividing both sides by 15

\sqrt{n} = 20*1.555

(\sqrt{n})^2 = (20*1.555)^2

n = 967.2

Rounding up:

The administrator should sample 968 students.

The points (10, w) and (3, 1) fall on a line with a slope of 0. What is the value of w?
sveticcg [70]

Answer:

w = 1

Step-by-step explanation:

If the slope is 0, then this line will be horizontal.

This means that the y value will be the same for all points on the line.

Since we are given the point (3, 1), we know that the y value is 1. This means all other points on the line will have 1 as the y value.

So, w is equal to 1 because it is the y value in that ordered pair.

BRAINIEST + THANK YOU + 5 STARS IF CORRECT
hammer [34]

Answer:

The answer would be that this graph is NOT a proportional relationship.

La respuesta sería que este gráfico NO es una relación proporcional.

Step-by-step explanation:

The reason why this graph makes no relationship is because a relationship needs to be constantly equivalent to the past fraction. But would 2 be equal to 5 and 4 be equal to 10? Nope, that is why it is not a proportional relationship.

La razón por la cual este gráfico no tiene relación es porque una relación debe ser constantemente equivalente a la fracción pasada. ¿Pero sería 2 igual a 5 y 4 igual a 10? No, por eso no es una relación proporcional.
