In a sample of 100 randomly selected concert attendees, the concert organizers find that 11 of them left the show early. The con

cert originally had 2,040 attendees.
A. Use proportional reasoning to estimate how many of the total number of attendees left the concert early.

B. Suppose there are 3 concerts at this hall next week, and the total attendance will be 5,500. Use a percent expression to predict the number of these attendees who will leave a concert early next week.

Answer:

A) ≈22.4 concert attendees might have left early.

B) 605 attendees might leave early.

Step-by-step explanation:

A) 11/100, or 11%, of the sample left early.

    11% of all the concert attendees is (11/100) × 2040 ≅ 22.4

    attendees who might have left early.

B) 11% of the total attendance is 11% × 5500 = 605 attendees who might

    leave early.

Suppose you start at the origin, move along the x-axis a distance of 7 units in the positive direction, and then move downward p
Andru [333]

Answer:

The coordinates of your position are x=7, y=0 and z=-2 or in coordinates notation the point given by (7, 0, -2)

Step-by-step explanation:

Since you are starting from the origin of a coordinate system, the coordinates of you position are simply going to be how many units you have moved in each direction.

  1. 7 units in the positive x-axis direction gives you x=7
  2. Then, being in the x-axis, you move 2 units downward parallel to the z-axis. Here the downward gives you a negative sign for the z coordinate, hence, z=-2.
  3. Now, y=0 is given due to the fact that there is no movement in the y-axis direction or you can also say that all the movement have been perpendicular to the y-axis and therefore, your position in this axis is zero.

Records show that the average number of job applications received per week is 5.9. Find the probability of 6 job applications re
german

Answer:

16.05% probability of 6 job applications received in a given week.

Step-by-step explanation:

When you have the mean during an interval, you should use the Poisson distribution.

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

In which

x is the number of sucesses

e = 2.71828 is the Euler number

\mu is the mean in the given interval.

Records show that the average number of job applications received per week is 5.9.

This means that \mu = 5.9

Find the probability of 6 job applications received in a given week.

This is P(X = 6).

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

P(X = 6) = \frac{e^{-5.9}*(5.9)^{6}}{(6)!} = 0.1605

16.05% probability of 6 job applications received in a given week.
