Every whole number is a rational number because whole numbers can be written as fractions.
Answer:
A. the mode.
Step-by-step explanation:
Mean
Sum of all values divided by the number of values, so is affected by an outlier present in the data-set.
Standard deviation:
Square root of the sum of the differences squared between each value and the mean, divided by the sample size. As it's related to the mean, it is affected by an outlier.
Range:
Subtraction of the largest value of the data-set by the smallest value, and thus, is also affected by an outlier.
Mode
Value that appears the most often in the data-set, and thus, not affected by an outlier, which means that the correct answer is given by option A.
Option A:
Slope of the line is .
Solution:
Given points are (1, 1) and (7, 5).
To find the slope of the line:
Slope of the line:
Hence slope of the line is .
Option A is the correct answer.
Answer:
Step-by-step explanation:
You are given three numbers: 3, 2+2i and 2-2i. Number 3 is a real number and numbers 2+2i and 2-2i are two conjugate complex numbers.
If the polynomial has a complex number as its root, then it also has the conjugate complex number as its root.
In your case, complex numbers 2+2i and 2-2i are conjugate to each other, so the polynomial of the smallest degree is
