Answer:
B) 105 is the right answer :D
Explanation:
I took the quiz for it!
Answer:
0.2776
Explanation:
Mean = 15000, SD = 1500
We need to find Cumulative probability: P(X > 15884)
First we need to convert it into normal distribution.
From the attached file, we can see the shaded area we are looking for.
For conversion as follow; 
Next to find Z =
= 0.59
now we have converted to normal distribution and found the value of Z, we need to find the probability P(X > 15884).
P(X > 15884) = P(Z > 0.59).
From the normal distribution table at Z= 0.59, and greater than 0.59, Probability = 0.2776.
For a cell reaction to be sponteanous, the standard cell potential must be positive.
<h3>What is a sponteanous cell reaction?</h3>
We define a cell reaction as sponteanous when the value of the standard cell potential is positive. If the standard cell potential is negative then the reaction is not sponteanous.
The question here is incompete but we know that the reactions that are sponteanous will all have a positive standard cell potential.

Someone has asked this question before and I answered it I don’t want to type it all over again so here
