What is the average(arithmetic mean)of all even integers between -5 and 7

Answers

Data:
all even integers between -5 and 7 = \{-4,-2,0,2,4,6\}
Number of even integers: 6 numbers
The simple arithmetic mean (A.M) is obtained by dividing the sum of the observations by their number.

A.M =  ((-4)+(-2)+0+2+4+6)/(6) =  (6)/(6) \to\:\boxed{A.M= 1}\end{array}}\qquad\quad\checkmark

Answer:
\boxed{\boxed{Arithmetic\:Mean=1}}

For the graph shown, select the statement that best represents the given system of equations.Number graph ranging from negative five to five on the x axis and negative six to four on the y axis. A line with a negative slope is drawn on the graph.
6x + 4y = 2
3x + 2y = 1

A.
not enough information

B.
coincident

C.
consistent and independent

D.
inconsistent

Answers

Answer:

B. coincident

Step-by-step explanation:

An coincident system of equations means that it has infinite solutions, because one line is on the other one. This happens when their equation are the same, or their "parent" line is the same.

So, given equations are:

6x + 4y = 2 and 3x + 2y = 1

Observe that if we divide the first by 2, we have

(6x + 4y)/(2)=(2)/(2)\n(6x)/(2)+(4y)/(2)=1\n  3x+2y=1

As you can see, using the first equation, we found that it has the same "parent" equation than the second equation. In other words, they are basically the same. This means that they represent the same line, so, the system is coincident and they have infinite solutions.

After analyzing the data provided in this question one can conclude that they are coincident. For the first system equation we have: 6x + 4y = 2. If we divide everything by 2 we will get: 3x + 2y = 1. Coincident means the same line.


The answer is choice B). Coincident.

I hope it helps, Regards.

Answers

Divide $204 by 12 bookends, then you have your answer.

Write an equation of a line in slope-intercept form if the slope is ½ and the y-intercept is -2.(A) y = (½)x + 2
(B) x - 2y = -4
(C) y = (½)x - 2
(D) 2y = x + 4

Answers

I was just learning about this. Okay,
First we need to plug in the values of the slope intercept form y = mx + b. b is the y-intercept so it is -2.

y = mx + -2.

Now lets find the rate of change or mx. the slope is 1/2 so the rate of change is 1/2. Lets plug in the value. 

y = 1/2x + -2

The answer is A. Hope this helped!!

Select the proper placement for parentheses to speed up the addition for the expression 4 + 6 + 5 A. (5 + 6) + 4   B. (4 + 6) + 5   C. 4 + (6 + 5)   D. (5 + 4) + 6

Answers

im guessing that by making 10 it will speed up the addition process so it should be 
B since (6+4) = 10 then +5 =15
the answer is B becuase 6+4=10 10+5=15
