Answer:x= 10
Step-by-step explanation:
Answer:
The correct answer is (b).
Step-by-step explanation:
A line is parallel to the axis if it has a slope equal zero. Then if we compute the slope of the line that joins the points then
This implies that the line which that joins this points is parallel to the x-axis.
Observe that the slopes of the lines corresponding to the other items are nonzero.
Option B:
Option D:
Solution:
<em><u>Polynomial definition:</u></em>
A polynomial can have constants, variables and exponents and fractional coefficient.
A polynomial cannot have fractional exponent, negative exponent and never division by a variable.
To select the expressions that would be considered as a polynomial.
Option A:
√x is not, because the exponent is ½. Fractional exponents are not polynomials.
This is not a polynomial.
Option B:
A polynomial can have constants, variables and exponents.
This is a polynomial.
Option C:
Fractional exponents are not polynomials.
This is not a polynomial.
Option D:
Fractional coefficients are allowed.
This is a polynomial.
Hence and are polynomial.
Answer:
The answer is B - 1/2.
Step-by-step explanation:
I got it right
MAD = Σ|x - mean|/n
mean = (<span>0 + 1 + 1 + 2 + 5 + 9)/6 = 18/6 = 3
MAD = (|0 - 3| + |1 - 3| + |1 - 3| + |2 - 3| + |5 - 3| + |9 - 3|)/6 = (3 + 2 + 2 + 1 + 2 + 6)/6 = 16/6 = 2.7 countries.
