Mean is when you add all of them together and divide by the amount of data you collected. Mean is considered the average. So, all of them added together would be 14. Divide that by 7. You should get 2 and that is the average.

. Write an equation of the line that passes through the given points use point

Damm [24]

Answer:

$y = \frac{1}{3}x+\frac{1}{3}$

Step-by-step explanation:

First, we need to figure out a linear equation. When given two points - $(x_{1}, y_{1})$ and $(x_{2}, y_{2})$ - first subtract $y_{1}$ from $y_{2}$ and and $x_{1}$ from $x_{2}$ . So in your situation, it will be $2-1$ and $5-2$ . That equals $1$ and $3$ , so your slope (how much the line moves up/down per unit) will be $\frac{1}{3} x$ .

Next, we need to find the y-intercept. To solve using point-slope form, we will plug our numbers in:

$y-y_{1} = m(x-x_{1})\\y-1=\frac{1}{3}(x-2)\\y-1=\frac{1}{3}x-\frac{2}{3}\\/+1=//+1\\y = \frac{1}{3}x+\frac{1}{3}$

So our final equation is $y = \frac{1}{3}x+\frac{1}{3}$ , which passes through both $(2,1)$ and $(5,2)$ . Hope this helps :)

write this sentence into an inequality.- The weight limit of the desk is a maximum of 40 pounds. PLZ TELL ME QUICK

dusya [7]

-- The LIMIT is 40 pounds.

-- The weight HASTA be 40 pounds or less. It can't be more.

-- 40 pounds is OK, and anything less than 40 pounds is OK too.

-- 41 pounds or more is too much.

-- Here are all the OK conditions:
. . . . Weight = 40 pounds.
. . . . Weight is less than 40 pounds.

-- Summary: Weight can be equal to 40 pounds or less than 40 pounds.

Can you write that same sentence with the mystical symbols of Math ?

How about W ≤ 40 lbs
