PLEASE HELP/kinda easy maths but I don’t get it/I’ll give brainiest award thingy

The product of the dimension must be 16.

In the first line, you have 1*1*16=16.

In the second line, you have 1*2*8=16.

In the third line, you start with 1 again. So, you need two more numbers that give 16 when multiplied, which are not 2 and 8. You don't have many choices.. :)

Similarly, in the last line, you start with 2. This means that the two missing numbers must give 8 when multiplied, and they can't be 1 and 8 (already used in the second line). Again, there are not many options.

Try to work this out on your own!

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
