Where is the z in the question
Answer:
2.3 is the probality to 6
Step-by-step explanation:
If only 13% remain, then you need to multiply the original amount by 13% or .13
So, 2120(.13)=275.6 This is rounded to the nearest 10th
Let the initial mass be represented by . Therefore, .
Let the final mass (or present mass be represented by . Therefore, .
Now, we are given that the rate of decay is 8% or 0.008 per day. Therefore, the amount of substance remaining after each day will be . Let us represent this by .
Please note that the equation guiding such decays is always given by:
, where t is the time.
Thus, the above equation will give in our case:
Taking natural logarithm on both sides we get:
Therefore,
days<9 days
Thus, in 9 days there will be further decay and the sample left will definitely be less than 115 milligrams.
The only option which matches this reality is Option C. Therefore, Option C is the correct answer.

Answer:
B. The triangle in question may or may not be a right triangle
Step-by-step explanation:
The length of the third side of the triangle may have any measure between 0 and 2. The triangle will only be a right triangle if the third side has length √2.
The triangle may or may not be a right triangle.
