Answer:
The value of variable r in the equation 
is 
Step-by-step explanation:
We need to find the value of variable r in the equation
Step 1: Write the equation
Step 2: Subtract 4 on both sides
Step 3: Divide both sides by 4
So, The value of variable r in the equation is
Answer:
1/3(0.3333333333%)
Step-by-step explanation:
There are six sides, and you can only land on one at a time on each die, so there is a one-in-three chance of landing on a three.
We have:
and:
so:
It is a finite sum, so it is convergent.
Answer:
Equations are composed for many expressions.
Expressions can indicate variables, constants, etc.
Best regards
Probability =
(number or amount of possible successes)(total number or amount of possible outcomes)
Area of any circle is (pi) x (radius squared)
Area of the whole board = (pi) x (13 squared) = 169 pi square inches
Area of the shaded region = (pi) x (5 squared) = 25 pi square inches
Probability = (success area) / (total possible area) = 25pi/169pi = <u>0.15 </u>(rounded)
Notice that if you do it my way ... keep 'pi' in the fraction ... you don't even
need to know what the value of 'pi' is, because there's one in the top and
bottom of the fraction, and they cancel.
