Answer:

d. Correlation

Step-by-step explanation:

Based on the information being provided it can be said that this technique provides the correlation between two or more variables. Correlation explains any statistical relationship that exists between two different variables or sets of data, whether it is casual or not. Many times it is the degree to which a pair of variables are linearly related

On the last day of school the fifth grade class has a picnic at the city park. Exactly 182 students and 274 adults are signed up
mamaluj [8]

Answer:

38 Tables

Step-by-step explanation:

First, we need to add the number of students with the number of adults to get the total number of people attending the picnic.

182 + 274 = 456

Next, we divide that number by how many people fit at each table to find how many tables we need.

456 people ÷ 12 people at each table = 38 tables.

Hi, could you help answer the questions in the image below?
ExtremeBDS [4]
In the second picture, top left is order 2, top right is order 4, bottom right is order 4, bottom left is order 2 I think but I'm not positive on that one. That's all I know for now, I'm currently in Calculus so my Geometry is a bit rusty.

Brums [2.3K]

Answer:

  • 150° and 210°
  • 0

Step-by-step explanation:

It is convenient to memorize the trig functions of the "special angles" of 30°, 45°, 60°, as well as the way the signs of trig functions change in the different quadrants. Realizing that the (x, y) coordinates on the unit circle correspond to (cos(θ), sin(θ)) can make it somewhat easier.

__

<h3>20.</h3>

You have memorized that cos(x) = (√3)/2 is true for x = 30°. That is the reference angle for the 2nd-quadrant angle 180° -30° = 150°, and for the 3rd-quadrant angle 180° +30° = 210°.

Cos(x) is negative in the 2nd and 3rd quadrants, so the angles you're looking for are

 150° and 210°

__

<h3>Bonus</h3>

  You have memorized that sin(π/4) = √2/2, and that cos(3π/4) = -√2/2. The sum of these values is ...

  √2/2 + (-√2/2) = 0

_____

<em>Additional comments</em>

Your calculator can help you with both of these problems.

The coordinates given on the attached unit circle chart are (cos(θ), sin(θ)).
