Answer:
x - 3y + z
Step-by-step explanation:
Terms are just names for objects inside the equation -- anything that isn't an operation. A coefficient the is the number a given term (variable) is being mulitpled by. In this case, -3 for y, and 1 for. x. We can deduce from this the start of the expression (x has no coeff. bc of multiplicative identity)
x - 3y
We know we are missing one term, and we also know that the third term cannot be constant, so it must be another variable. In this case I have chosen Z, in theory it shouldn't really matter but z is the best variable name in this case.
The dataset 78 is an outlier of the dataset
<h3>How to determine the true statement about the outlier?</h3>
The dataset is given as:
1, 12, 13, 15, 18, 20, 35, 37, 40, 78
Where
Q1 = 13
Q3 = 37
The boundaries of the outliers are given as:
L = Q1 - 1.5 * (Q3 - Q1)
U = Q3 + 1.5 * (Q3 - Q1)
Substitute the known values in the above equation
L = 13 - 1.5 * (37 - 13) = -23
U = 37 + 1.5 * (37 - 13) = 73
This means that the data elements outside the range -23 to 73 are outliers.
78 is outside this range
Hence, 78 is an outlier of the dataset

Answer:
The answer to your question is the letter A.
Step-by-step explanation:
a) - c < 0 This option is correct c > 0 but -c < 0 or 7 > 0 and -7 < 0
b) c < -a This option is incorrect. 7 > - (-4) or 7 > 4
c) c < - b This option is incorrect. 7 > - 1
Conclusion
The right answer is the first choice because is the only that satisfies the inequality.
The answer is true. .........
