The sample space is nothing but ALL possible outcomes. In this case you have Black & Red id's. Then the sample space is {black, red}
<span>(7x+3)-(2x+1)
=</span><span>7x + 3 - 2x - 1
= 5x + 2</span>
Slope of <span>y= x/6-5 = 1/6</span>
Answer:
A. 
Step-by-step explanation:
Given:
Volume of the cylindrical container before dilation, 
Scale factor of the dilation, 
Therefore, the volume of the dilated cylinder is given as:

Plug in 1 gal for
and
for SF. Solve for
. This gives,

Therefore, the volume of the dilated cylinder is
gallons.
Since it has a half life of 60 days, this means that every 60 days it multiplies by 0.5. Since it asks for 300 days, your equation is 500*(0.5)^5, which is 15.625 mg left after 300 days.
