Question

*need to know in the next hour*

teddy is preparing to sell some wooden blocks at a garage sale. before pricing individual bags of blocks, he decides to determine the approximate number of blocks per pound be researching the weights of different sets of blocks. the graph shows his data.

about how many blocks are there per pound? round the the nearest block.

Answer 1

20 blocks per pound

Explanation:

We can see the line of best fit goes through the points (0, 0) and (5, 100). WE will use these to find the slope:

`m=(y_2-y_1)/(x_2-x_1)`

Using our points,

`m=(100-0)/(5-0)\\\\=(100)/(5)\\\\=20`

This makes the slope 20 blocks per pound.

Answer 2

There are 20 blocks per pounds.

Explanation:

Given: A best fit line graph for the number of blocks per pound by researching the weights of different sets of blocks.

We have to find the number of blocks per pounds.

Consider the given best fit line graph.

We consider two points through which line passes.

Since, Point (2.5,50) and (5,100) lies on the line.

Slope of line gives the number of blocks per pounds.

Slope between two points is given as

`\mathrm{Slope}=(y_2-y_1)/(x_2-x_1)`

`\left(x_1,\:y_1\right)=\left(2.5,\:50\right),\:\left(x_2,\:y_2\right)=\left(5,\:100\right)`

We get,

`m=(100-50)/(5-2.5)`

Simplify, we have,

m = 20

Thus, there are 20 blocks per pounds.
