<span>This is a simple subtraction question. To find the answer, you simple need to subtract 15 from 104. This equals 89, so there were 89 4th graders at school that day in total. In the instance you're unsure that a subtraction equation is right, you can also add your answers back together to double check, so 89 + 15 = 104.</span>
The Venn Diagram that represents the problem is shown below
P(E|F) and P(F|E) are the conditional probability.
P(E|F) is given by P(E∩F) ÷ P(F) = ¹/₂ ÷ ¹/₂ = 1
P(F|E) is given by P(F∩E) ÷ P(E) = ¹/₂ ÷ ¹/₂ = 1
To find the awnser, the equation would be: the volume of the can - the volume left
to find the value,we can use 3.14 for 丌
The volume of the can would be the base area (丌r^2)times it's height,which in this case the volume is:
3.14(5)^2×12
=3.14×25×12
=942 cm³
The volume left:
3.14(5)^2×4
=314cm³
Thus,Mishka used:
942-314
=628 cm³
The answer is 628cm³
Hope it helps!
