Answer:
Systematic error
Step-by-step explanation:
Assuming that none of the judges are biased, the most likely reason for this difference is the occurrence of systematic errors.
Systematic errors are errors introduced by inaccuracy in the experimental design, be it in the observation or measurement process.
In this case, the reaction time from observing the finish and stopping the clock for each judge might be different, which configures a systematic error.
We need to find the quotient of the given division problem.
In order to find its quotient, we will use long division.
)
First of all, we put x in the quotient as 
goes into 
, x times.
So, we get:
)(x
Upon subtracting, we get:
We can see that goes into 
, -2 times, therefore, the next term in the quotient will be -2. This makes our quotient as (x-2).
Answer:
Only A, E, and F are correct.
Step-by-step explanation:
The difference between two points is 
, thus the difference between the height of the Pelican and the height of the Heron is 
, and between the Pelican and the trout it is 
.
The distance between two points is just the absolute value of the difference between them. Between the Pelican and the Heron it is
, and the distance between the Pelican and the Trout is 
.
Therefore,
A is correct;
B is incorrect (difference is not positive);
C is incorrect (distance cannot be negative);
D is incorrect (difference is not positive);
E is correct;
F is correct;
The domain is the x values
y = 2 - x
when x = -3
y = 2 - (-3)
y = 2 + 3
y = 5....so ur points are (-3,5)
when x = -2
y = 2 - (-2)
y = 2 + 2
y = 4....so ur points are (-2,4)
when x = -1
y = 2 - (-1)
y = 2 + 1
y = 3...so ur points are (-1,3)
when x = 0
y = 2 - 0
y = 2....so ur points are (0,2)
when x = 1
y = 2 - 1
y = 1...so ur point are (1,1)
so basically, u plot all of those points
Isosollese triangle has 2 equal sides that are longer than legnth of base
perimiter=15.7
equation is 2a+b=15.7
so if the longer side is 6.3, wat is legnth of base
we know that identical sides are bigger so 6.3 is one of the identical sides
2a means the 2 idneical sides
2(6.3)+b=15.7
12.6+b=15.7
subtract 12.6 from btohs ides
b=3.1
answer is base=3.1 cm
