The correct answer is E. A fundamental basis of regression analysis is the assumption of the existence of two independent variables for every dependent variable.

Regression analysis is a statistical method that examines the dependence of a response variable on selected explanatory variables.

When studying the dependence between quantities and trying to describe a given functional dependence on a given formula, it is assumed that the dependence consists of a precisely determinable component and a random component. The relationship with this assumption is called the regression model.

In a class of 29 students, 19 are female and 14 have an a in the class. there are 8 students who are male and do not have an a i
vodomira [7]

Answer:

5/ 19 ≈ 0.26 = 26%

Step-by-step explanation:

given: student is female. there is a 100% chance that the student is female

probability we want = (favorable outcomes) / (total outcomes)

total outcomes = 19 because there are 19 female students and the student must be female

favorable outcomes = 19 - 14 = 5 females who do not have an A in the class

probability = 5/ 19 ≈ 0.26 = 26%

ASAP What is the lateral area of this regular octagonal pyramid?? Explain your answer if you can plz thanks
Archy [21]
The lateral area would be 298.7 cm².

The lateral area is the area of all of the lateral faces of the pyramid.  There are 8 triangles making up the lateral faces.  Each has a base of 6.6.  The formula for the area of a triangle is

A=1/2bh,

so we still need the height of the triangle.

The height of each lateral triangle is the slant height of the pyramid.  The slant height of the pyramid forms a right triangle with the height of the pyramid and the "radius" as it were of the pyramid.  Thus we use the Pythagorean theorem:

8²+8²=h²
64+64=h²
128=h²
√128=√(h²)
8√2 = h

Substituting this into our area formula we have:
A=1/2(6.6)(8√2)

We will go ahead and multiply this by 8, since there are 8 lateral faces:
LA=8(1/2)(6.6)(8√2)
LA = 298.7

The first step in beginning to control your time is
kotegsom [21]
B. DEVELOPING A TIME LOG is the first step in beginning to control you time.

A. A COMBINATION OF LETTERS AND NUMBERS password is used to ensure security.


Time log is basically you recording or logging the activities you have done in a certain time of a day. As you do this daily and check on the log for a few days, you will notice that you have done things that are either unimportant and time consuming, in short time was wasted.
Time log is very helpful especially is you are very busy. It will not only help you manage your tasks in any given time, it will also show you the things you can do in a shorter amount of time and allow you to schedule time for relaxation.

Passwords should be composed of a combination of letter and numbers. Other use special characters just to tighten password security. It is better that users create passwords that may form a special meaning to them so that they will not forget it regardless of length and combination.
