Answer:

Step-by-step explanation:

A vertical line has slope that is "undefined". Line R is the vertical line on your graph.

_____

The slope of a vertical line is "undefined" because of the way slope is defined. Slope is the vertical change divided by the horizontal change. When the line is vertical, there is no horizontal change, so the computation of slope involves division by zero. The result of division by zero is "undefined."

Answer:

The other prime number is 2.

Step-by-step explanation:

Prime factorization of a cube of a certain number and a square of 5

The number we dont know is x, so we have:

$x^3 \times 5^2 = 25x^3$

The product is 200. What is the other prime number?

$25x^3 = 200$

$x^3 = \frac{200}{25}$

$x^3 = 8$

$x = \sqrt[3]{8}$

$x = 2$

The other prime number is 2.

Suppose it is known that 60% of radio listeners at a particular college are smokers. A sample of 500 students from the college i

vladimir1956 [14]

Answer:

The probability that at least 280 of these students are smokers is 0.9664.

Step-by-step explanation:

Let the random variable X be defined as the number of students at a particular college who are smokers

The random variable X follows a Binomial distribution with parameters n = 500 and p = 0.60.

But the sample selected is too large and the probability of success is close to 0.50.

So a Normal approximation to binomial can be applied to approximate the distribution of X if the following conditions are satisfied:

1. np ≥ 10

2. n(1 - p) ≥ 10

Check the conditions as follows:

$np=500\times 0.60=300>10\\n(1-p)=500\times(1-0.60)=200>10$

Thus, a Normal approximation to binomial can be applied.

So,

$X\sim N(\mu=600, \sigma=\sqrt{120})$

Compute the probability that at least 280 of these students are smokers as follows:

Apply continuity correction:

P (X ≥ 280) = P (X > 280 + 0.50)

= P (X > 280.50)

$=P(\frac{X-\mu}{\sigma}>\frac{280-300}{\sqrt{120}}\\=P(Z>-1.83)\\=P(Z$

*Use a z-table for the probability.

Thus, the probability that at least 280 of these students are smokers is 0.9664.

Solve the linear system using substitution y - 5 = x 4x - y = 4

Agata [3.3K]

Step-by-step explanation:

X=y-5

Now,

4x-y=4

4(y-5)-y=4

4y-20-y=4

3y=24

Y=8

Substituting the value of y

8-5=x

X=3

Can someone help me solve the maze?

Ierofanga [76]

Answer:

see attached

Step-by-step explanation:

This is asking you to recognize the symbols used to designate a point, line segment, ray, angle, line, and plane.

The point is designated by its letter.

A line segment is designated by the letters of its endpoints, with an overline.

A ray is designated by the endpoint and a point on the ray. The endpoint is listed first. The letters have an arrow over them pointing in the direction from the endpoint.

An angle is designated using the symbol ∠. If three letters are used to identify the angle, the middle one is the vertex.

A line is designated using its name, or by the letters of two points on the line. If the letters are used, there may be a double-ended arrow over them.

A plane is designated by 3 non-collinear points, for example, "plane ABC". It may also be designated by the name of the plane.
