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:
x=60
Step-by-step explanation:
1. Add all the 12's on the right side together = 48
2. then you add the 12 on the left side to the right side to make it = 60
3. X=60!

Answer:
Equation translates to 289 + y = 206
it solves to y = -83
====================================================
Explanation:
The "and y more" means we are adding y onto 289 to get the expression 289+y. This is set equal to 206 because of the term "is" in the original statement.
Therefore, "289 and y more is 206" translates fully to the equation 289+y = 206
This is the same as saying y+289 = 206
To isolate y, we undo what is happening to it. We are adding 289 to it, so we must subtract 289 from both sides
y+289 = 206
y+289-289 = 206-289
y = -83
So we are adding -83 to 289 to get 206

Answer:
The number cupcakes Ms. Ciervo can make using the
teaspoons of vanilla is 29.
Step-by-step explanation:
The information provided is:
- Ms. Ciervo has
teaspoons of vanilla. - Each cupcake needs to have
teaspoon of vanilla.
Compute the number cupcakes Ms. Ciervo can make using the
teaspoons of vanilla as follows:
Amount of vanilla required for one cupcake =
teaspoons
Total amount of vanilla available
teaspoons.


Thus, the number cupcakes Ms. Ciervo can make using the
teaspoons of vanilla is 29.
