Answer:
Mode.
Because it is used to determine the most frequently occurring item which in this case is movie.
Step-by-step explanation:
The 3 measure of central tendencies are namely;
Mean, median mode.
- Mean is defined as the average of a set of data.
- Median is the middle term of a set of data that splits that set of data into 2.
- Mode is the term that occurs most frequently in a set of data.
In this question, we want to find the movies most frequently watched.
Thus, from the definitions above earlier, it is clear that the only way to know this is using the mode.
Answer:
m - 1
c - 6
Step-by-step explanation:
The equation is in slope-intercept form.
y = mx + c
m - slope
c (or b) - y -intercept
Usually if the slope is one it will not be written.
y = 1x + 6
The slope is one.
6 takes 'c's place, so it is the y-intercept.
Hope this helps.
Answer: A centroid of a triangle is the point where the three medians of the triangle meet that is what i got on my test hope this helps :)
Answer:
Now: 6 yr mean age
in 10 yrs? 16 yr mean age
in 20 yrs? 26 yr mean age
Why? Because regardless of the relationship between each sibling's age, your always adding the 10yrs to each individual, which you are then dividing out to determine the mean age. See proof below:
Including anita, there are 6 people. We'll define each age as an unknown variable. Assume we know nothing about the relationships between their ages
for example sake
anita's age = a
sister 1's age = b
sister 2's age = c
brother 1's age = d
brother 2's age = e
brother 3's age = f
Now:
mean age = (a + b + c + d + e + f)/(6 people) = 6 yrs
in 10 yrs:
mean age = ((a+10) + (b+10) + (c+10) + (d+10) + (e+10) + (f+10))/(6 people)
mean age = (a + b + c + d + e + f + 60)/(6 people)
mean age = (a + b + c + d + e + f)/(6 people) + (60)/(6 people)
mean age = (a + b + c + d + e + f)/(6 people) + 10
Notice the first term is the same expression of the mean age for "Now"
Thus, in 10 yrs:
mean age = 6 + 10 = 16 yrs
The same principle applies for "x" yrs from now, as long as we know what the mean age is "Now"
