Answer:
1. It increases at 0-15 minutes
2. The rate of change is 3 and I got it by using the formula; to calculate. So the line went up 15 and right 5 times so it'll be 15/5 = 3
3. It stays constant from 15-35 minutes.
4.The rate of change is 0 because the rate of change for every horizontal line is 0.
5. It decreases from 35-45 minutes
6. The rate of change is -4 and I got it by using the formula; to calculate. So the line went down -20 and right 5 times so it'll be -20/5 = -4
7. The rate of change is negative because the line is going down which means that the line is negative.
Step-by-step explanation:
1. As you can see the line is going up which means its increasing.

Answer:
Step-by-step explanation:
We start by selecting our pivot column as the most negative value on the bottom row.
This means our pivot column is . We now generate a new column by diving our pivot value by our value on the right-most column. This gives us (on a new row)
P/V
12/1 = 12
4/2 = 2
4/1 = 4
We pick our smallest positive value to be our pivot row.
This means our pivot row is our second row, and our pivot column is our first column. We now divide our entire row by our pivot point (our intersection of these two pivots)
This gives us our new second row as
1 3 0 1/2 0 0 2
now we need to eliminate our values from our other rows.
old row 1 - new row 2 gives us new row 1
row two stays the same
old row 3 - new row 2 gives us new now 3.
old row P + 2 new row 2 gives us new row P
After the first iteration of this algorithm this gives our tableau as: (see attached screenshot)
Answer:
And using the probability mass function we got:
And adding the values we got:
The best answer would be:
D. 0.377
Step-by-step explanation:
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
For this case in order to pass he needs to answer at leat 6 questions and we can rewrite this:
And using the probability mass function we got:
And adding the values we got:
The best answer would be:
