Answer: Probability that both tests detect the bacteria is 83.66%.
Step-by-step explanation:
Since we have given that
Probability of the first test giving accurate results = 84%
Probability of the second test is accurate = 89%
Probability of both tests detect the bacteria is given by

Hence, Probability that both tests detect the bacteria is 83.66%.
14. (y+x=-2)3
2x-3y=31
3y+3x=-6
2x-3y=31
the y variables cancel out
5x=25
5x÷5=25÷5
x=5
y+5=-2
-5. -5
y=-7
Based on the given parameters, the value of Rx is R18
<h3>How to determine the value of Rx?</h3>
The given parameters are:
Number of people = 25
Amount paid = Rx
Additional people of 5 = Amount paid being R3 less
The total amount paid is calculated using:
Total amount = Number of people * Amount paid
Substitute the known values in the above equation
Total amount = 25 * x
Total amount = (25 + 5) * (x - 3)
Substitute Total amount = (25 + 5) * (x - 3) in Total amount = 25 * x
(25 + 5) * (x - 3) = 25 * x
Evaluate the sum
30 * (x - 3) = 25 * x
Evaluate the products
30x - 90 = 25x
Collect like terms
30x - 25x = 90
Evaluate the like terms
5x = 90
Divide both sides by 5
x = 18
Hence, the value of Rx is R18
