Answer:

The population of interest for this student is the students whom are enrolled in statistics classes.

Step-by-step explanation:

Sampling

This is a common statistics practice, when we want to study something from a population, we find a sample of this population.

For example:

I want to estimate the proportion of New York state residents who are Buffalo Bills fans. So i ask, lets say, 1000 randomly selected New York state residents wheter they are Buffalo Bills fans, and expand this to the entire population of New York State residents.

The population of interest are all residents of New York State.

A simple random sample of 500 students was selected from all the students enrolled in statistics classes.

This means that the population of interest for this student is the students whom are enrolled in statistics classes.

I REALLY NEED HELP!!!!!!!!!!!!

Answer: 64 centimeters squared.

Step-by-step explanation: This shape is a parallelogram. And the area of a parallelogram is just the base multiplied by the height. Here, the base is 10 cm and the height is 7 cm. So you might think the the area is just 70 centimeters squared. But here's the catch. There is a rectangular region in this parallelogram that is not shaded. But you can still easily solve this problem. All you need to do is find the area of that rectangular region and you already know the length and the width of this region. And, remember, the area of a rectangle is just the length and the width multiplied. So here, the area of that rectangular region is just 2 cm multiplied by 3 cm. Which will give you 6 centimeters squared. Now, all that's left to do is subtract the area of that rectangular region, 6 centimeters squared, from the total area of the parallelogram, 70 centimeters squared. And that should give you 64 centimeters squared as your final answer. I really hope this makes sense and is helpful.

Elizabeth bought a cheese pizza. It was served on a metal tray with a diameter of 22 centimeters. What is the tray's area?
agasfer [191]
<h3>Answer:</h3>

The Area of the tray ≈380 cm

<h3>Solution:</h3>
  • We are given the diameter of the tray, which is equivalent to 22 cm.
  • We are asked to find the area of the tray.
  • Remember the formula:
  • Area of a circle = πr²
  • Where
  • π -> pi (3.14...)
  • r -> radius
  • Notice that we aren't given the radius. We're given the diameter only.
  • No reason to panic. We can easily find the radius by dividing the diameter by 2.
  • The radius is equal to 11 cm.
  • Now, plug the values into the formula:
  • A=π(11)²
  • A=121π
  • A≈380 cm

Hope it helps.
