6A. Lisa assumes that she can get a score of thirty points on her math test without doing any studying and that she can increase her test scores by eight points for every
hour of study. Find the linear function that gives Lisa's score on the test after t hours
of studying

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

78.59 is the mean
