Step-by-step explanation:
u vector components:
x-comp = 8 - (-17) = 25
x-comp = -11 - 4 = -15
Therefore, we can write vector u as
u = 25i - 15j
v = 14i - 4j
u - v = 11i - 11j
Therefore,
2(u - v) = 22i - 22j
Answer:
9r²(r - 8)
Step-by-step explanation:
Step 1: Write expression
9r³ - 72r²
Step 2: Factor out 9
9(r³ - 8r²)
Step 3: Factor out r²
9r²(r - 8)
Answer:
A. Statistic
Step-by-step explanation:
Usually whole population is difficult to cover so the part of population is considered to assess the aspects of population. The statistic is the quantity which summarizes the sample. The problem illustrate that summary measure is calculated from sample to describe a population. As the summary measure is computed from sample then it is a statistic.
The X=1 is Y= 5
The x=0 is Y= 8
The x=3 is Y= -1
