Katen [24]

Teacher will have 3 bottles of glue after he combines

<em><u>Solution:</u></em>

Given that,

The art teacher has 7 bottles of glue that are each 2/5 full

He combines them so he will have fewer bottles

<em><u>To find: bottles of glue does he have after he combines them</u></em>

From given,

Total bottles = 7

Each is 2/5 full

Therefore, multiply 7 with 2/5 to get total bottles of glues he will have after combining

Number\ of\ bottles\ of\ glues = 7 \times \frac{2}{5}\\\\Number\ of\ bottles\ of\ glues = \frac{14}{5} = 2.8 \approx 3

Thus teacher will have 3 bottles of glue after he combines

What would be the correlation coefficient (r) of the following scatter plot?
luda_lava [24]

Answer:

-0.89 (i think)

If its wrong then i'm not a smart person, and it's -0.15
