Answer:
i think is (-3,2) because it look like in negative and posted
Answer:
x=6,y=4,z=2
Step-by-step explanation:
Answer: 22j
Explanation:
1) From the graph you can calculate the vector v as folllows:
Translation of the extreme (-5,0) to the origin (0,0) implies add 5 units to - 5.
Then, add 5 units to the x-coordinate of the other extreme: 7 + 5 = 12; and keep the y-coordinate, which is 2.
Therefore, the coordinates of the vector v are (12,2)
2) Now you can find the vector v - 4u applying the operations to the coordinates of the two vectors:
v - 4u = (12,2) - 4(3, -5) = (12,2) - (12,-20) = (12 - 12, 2 + 20) = (0,22)
3) Changing the notation in terms to i, j; that is 0i + 22j = 22j
Answer:
The question is poorly phrased and ambiguous.
Step-by-step explanation:
This is a great example of how to poorly phrase a question so as to be ambiguous.
The answer you are probably supposed to give is "a population". To elucidate: the salary of each teacher in a school includes all the teachers in the school, hence the entire population of teachers in the school.
Another interpretation is that the population is all teachers in all schools, in which case the salary of each teacher in <u>a</u> school is "a sample" of all teachers.
