Help please few mins left!

The Mean is when we add up all the numbers then divide it by the amount of numbers.

26 + 26 + 25 + 30 + 20 + 31 + 41 = 193

Now we work out 193 ÷ 7 (Because if you count all the numbers we will find out that there are 7 of them).

193 ÷ 7 = 27.5714285714

The Mode is the most common number in the sequence.

If we order them up we will find that 20 is the mode.

20, 20, 25, 26, 30, 31, 41.

The Median is when we order the numbers up (You have to order them) then find the middle number.

20, 20, 25, 26, 30, 31, 41.

As you can see the middle number is 26, so the Median is 26.

The Range is when we subtract the highest number from the lowest number.

For this we will need to find which is the lowest in the sequence which is 20 then the highest which is 41.

Now we work out 41 - 20 = 21

Mean = 27.5714285714

Mode = 20

Median = 26

Range = 21

I hope this helped. Have a great day!

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
