Marcus score is 13.7, the mean is 12.89, and the standard deviation is 1.95, so I’ll do ( 13.7 – 12.89)/ 1.95, Since Marcus' z-score is 0.415. The area to the left of the z-score is 65.9% so therefore Marcus did scored better than 65.9% of the students. So Marcus needs to score 98% better of all the other students in order for him to receive an actual certificate.
Answer:


Step-by-step explanation:

To compute x times y must use foil on the right hand side.
First: 
Outer: 
Inner: 
Last: 
------------------------------------Add like terms:

----------------


Multiply top and bottom by bottom's conjugate:

Foil the top and just do first and last of Foil for the bottom since the bottom contains multiplying conjugates:

Replace
with -1:



<em><u>Answer:</u></em>
s = $39,340
<em><u>Explanation:</u></em>
Note: I will use the symbol "n" instead of "t" in the solution.
<u>The given formula is:</u>
s = 32,512 * (1.1)ⁿ where "n" is the number of years.
We want to get the salary after 2 years. This means that we will substitute with n = 2 in the above equation and get the value of s.
<u>This is shown as follows:</u>
s = 32,512 * (1.1)²
s = $39,339.52 which is approximately $39,340
Hope this helps :)
It means the speed (velocity) was constant - the object traveled the same distance per time period throughout the graph.
