the answer is A. the commutative property of addition. this property states that no matter what order you put the numbers, the outcome will be the same.
Hope this helps!
Answer:
The approximate probability that at least 2 children have been diagnosed with ASD among the 200 selected children is
0.01 or 1%.
Step-by-step explanation:
Number of selected children = 200
The probability of no child been diagnosed with ASD = P(None) = 198/200 = 0.99
Therefore, the probability of at least two children been diagnosed with ASD = 1 - 0.99 = 0.01.
This is the same as:
If 2 children have been diagnosed with ASD,
therefore, the approximate probability that at least 2 children have been diagnosed is:
2/200 = 0.01. This value is equal to 1%.
The above are summed up in:
The probability of at least one = 1/200 = 0.05
Therefore, the probability of at least two = 0.05 * 2 = 0.01
b) Generally, to find the probability of at least one event happening, we calculate the probability of none and then subtract that result from 1. That is, P(at least one) = 1 – P(none). For two events happening, the sum of the probability of at least one in two places is deducted from 1 to get the probability of at least two.
So this is going to be alot of writing to show my thinking but ill bold the answer.

that is 6 (that equal 4 or 8) out of 25
so your ratio would be 6:19
<h2>Hello!</h2>
The answer is:
The first measurement of volume is equal to 835.23 mL.
<h2>Why?</h2>
Boyle's Law equation can be used when the temperature is kept constant, and it establishes a relation between the pressure and volume, showing that when an ideal gas is kept constant, the pressure and volume are inversely proportional.
So, we Boyle's Law equation states that:
Where,
Now, if we are looking for the first volume measurement, we need to rewrite the equation as follow:
So, substituting the given information and calculating, we have:
Hence, the first measurement of volume is equal 835.23 mL.
Have a nice day!
