A third-degree polynomial has 4 intercepts.

1 answer:

3 0

Yes, if you are counting intercepts are both x and y-intercepts.

A third degree polynomial would only have 3 x-intercepts. However, it could also have a y-intercept. This would make the total number of intercepts 4.

What is the mean absolute deviation of the data: 10, 20, 15, 17, and 13?

Rufina [12.5K]

Answer:

2.8

Step-by-step explanation:

1) find the mean of the data set. = 15

2) find the abs value of the diff between each data value and the mean: |data value – mean|.

|10-15|=5, |20-15|=5, |15-15|=0, |17-15|=2, |13-15|=2

3) find the sum of the abs values of the diff = 14

4) divide the sum of the abs value by the number of data values = 14/5 = 2.8

1.Which expressions are polynomials? Select each correct answer. Pick more then one.

madreJ [45]

If all the power of the variables are greater than or equal to zero, then the expression is a valid polynomial.

So,

$7x^{7}-x-5$

$35x^{2}$

$\frac{x}{5}+2$

are polynomials.

$x^{2} -x\sqrt{2}$

2 + s

$4x^{2} +y$

are all polynomials.

If the degree of the polynomial is 3, then it is a cubic polynomial. If the number of terms of a polynomial is 3, then it is a trinomial.

Hence, $-5x^{3}-4x+1$ is a cubic trinomial.

The highest power is the degree.

Hence, degree of the polynomial is 2 + 4 = 6.
