Answer: 9
Step-by-step explanation:
Use Pythagorean's Theorem for a right triangle.
Answer:
Step-by-step explanation:
Given that:
The numbers of the possible public swimming pools are 5
From past results, we have 0.007 probability of finding bacteria in a public swimming area.
In the public swimming pool, the probability of not finding bacteria = 1 - 0.007
= 0.993
Thus;
Probability of combined = Probability that at least one public
sample with bacteria swimming area have bacteria
Probability of combined sample with bacteria = 1 - P(none out of 5 has
bacteria)
Probability of combined sample with bacteria = 1 - (0.993)⁵
= 1 - 0.9655
= 0.0345
Thus, the probability that the combined sample from five public swimming areas will show the presence of bacteria is 0.0345
From above, the probability that the combined sample shows the presence of bacteria is 0.0345 which is lesser than 0.05.
Thus, we can conclude that; Yes, the probability is low enough that there is a need for further testing.

Answer:
Yes, the ordered pair (1, 2) is a solution to the system.
Step-by-step explanation:
The answer can be found quite quickly. Simply substitute the x coordinate of the given pair for <em>x</em>, and the y coordinate of the given pair for <em>y</em>.
The x coordinate is 1 and the y coordinate is 2, so...
3(1) - 4(2) = -5
2=4(1)-2.
Next, simplify:
3-8=-5
This equation is TRUE.
2=4-2
This equation is also TRUE.
Hopefully, this helps in some way!
