Average 8, 14, and 11

Step-by-step explanation:

you add 8,14, and 11 to get 33 then you divide it by 3, because there are 3 numbers meaning the average is 11.

If that makes, all you have to do is add up all the numbers then divide by the amount of numbers you see to find the average of the numbers.

Hey there!

The word “average” is basically the “mean” of a data set. When you hear or see the word “average” in mathematics think of its asking you for your “total” in the data set.

Here’s the formula to make it easier to solve.

mean = sum of all terms / number of terms

YOUR EQUATION:

AVERAGE = 8 + 14 + 11 / 3

8 + 14 + 11 / 3

= 22 + 11 / 3

= 33 / 3

= 11

Therefore, your answer should be: 11

Good luck on your assignment and enjoy your day!

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12
