Step-by-step explanation:
The two vectors are:
- The weight of each of the semester's exams.
In decimal:
- The class average on each of the exams
In decimal:
-----------------------
Dot product:
Suppose there are two vectors, u and v
u = (a,b,c)
v = (d,e,f)
There dot product between the vectors u and v is:
u.v = (a,b,c).(d,e,f) = ad + be + cf
------------------
So
In terms of the class, the dot product represents the weighed class average.

Eddie walks 60.03 yards in 1 minute using proportion.
What is proportion?
The term proportionality refers to any relationship that has the same ratio every time. The proportional relationship between the two supplied ratios is defined by an equation. In other terms, the proportion declares that the two fractions or ratios are equal. For instance, the average number of apples per tree determines the proportionality between the quantity of apples in a crop and the number of trees in the orchard.
Here let us take time and distance as proportional values,
=>
=> 450.25/2.5 = x/1
=> x = 180.1 feet.
To convert feet to yards divide the length by 3. then
=> 180.1/3=60.03 yards,
Therefore Eddie Walks 60.03 yards in 1 minute.
