Answer:
13.8%
Step-by-step explanation:
I have created a table that shows all of the possibilities that two die's can roll when summed up. If we count all of these possibilities we can see that there are a total of 36 outcomes. From all of these outcomes we can also see that only 4 outcomes sum up to be a total of 5. Therefore, we have to divide the number of times 5 is a possibility by the total number of outcomes to get the probability of actually getting a sum of 5.
5 / 36 = 0.138 ... multiply by 100 to get percentage
0.138 * 100 = 13.8%
To find the answer,
Multiply the term with 4 then subtract with 3
Lets take the term as 'n'
Formula = 4n-3
Value of 8th term = (4*8)-3
= 32-3
= 29
The value of 8th term is 29
The surface is parameterized by
and the normal to the surface is given by the cross product of the partial derivatives of 
:
It looks like you're given
Then the normal vector is
Now, the point (2, 2, 0) corresponds to u and v such that
and solving gives 
, so the normal vector at the point we care about is
Then the equation of the tangent plane is
Not sure but my guess is answer B but you might want to check around be for taking my advice on this.
4 = $26
26/4 = $6.50
1 ticket = $6.50
6.5 x 3 =19.50
26+19.50 = 45.50
7 tickets = $45.50
