Answer:

x = 12 ft

Step-by-step explanation:

We know that by adding up all of the values of the sides, we will get the value of the perimeter. Using this information, we can set up an equation and simplify to find the variable.

16 + 20 + x + x = 60                         <----- The sum of the sides is the perimeter

16 + 20 + 2x = 60                            <------ Combine variables (x + x = 2x)

36 + 2x = 60                                    <----- Add 16 and 20

2x = 24                                            <----- Subtract 36 from both sides

x = 12                                               <----- Divide both sides by 2

Answer:

x=12

Step-by-step explanation:

16+20+2x=60\\36+2x=60\\2x=24\\x=12

the perimeter is the side lengths added together meaning it is

16+20+x+x=60. x+x can be simplified to 2x. now solve for x

Elodia [21]
This item can be solved by the probability theorem called Bayes' theorem which states that the probability of event A occurring given event B is equal to,
                            P(A/B) = P(A)P(B/A) / P(B)
where P(B/A) is the probability that the test will yield positive if the person has the disease. P(A) is the probability will be present in any particular person which is equal to 0.04. 

P(B) is the probability of positive result irrespective of whether the disease is present of not is calculated below.
                   P(B) = (0.94)x (0.04) + (0.06)(0.96) = 0.0952

Now, solving for P(A/B)
                            P(A/B) = (0.94)(0.04) / 0.0952 = 0.039
Thus, the answer is approximately 4%.
