2 goes in second box on the bottom
Step-by-step explanation:
i dont what goes in the first bottom box
Answer:
81.86%
Step-by-step explanation:
We have been given that final exam scores are normally distributed with a mean of 74 and a standard deviation of 6.
First of all we will find z-score using z-score formula.
Now let us find z-score for 86.
Now we will find P(-1<Z) which is probability that a random score would be greater than 68. We will find P(2>Z) which is probability that a random score would be less than 86.
Using normal distribution table we will get,

We will use formula
to find the probability to find that a normal variable lies between two values.
Upon substituting our given values in above formula we will get,


Upon converting 0.81859 to percentage we will get

Therefore, 81.86% of final exam score will be between 68 and 86.
The diagram that shows all the lines of symmetry is diagram B.
<h3>
Which diagram shows all the lines of symmetry of the regular hexagon?</h3>
We define a line of symmetry as a line such that if we perform a reflection over that line, the <em>image coincides with the preimage </em>(so the reflection does not change the figure).
<em />
With that in mind, any line that cuts the hexagon in exactly two halves is a line of symmetry.
So the image that shows all the lines of symmetry of the regular is B, where it shows all the lines that cut the hexagon in two equal halves.
