A monomial is a polynomial with 1 term

and ur answer would be C. 4

A and B are binomials (they have 2 terms)
D is a trinomial (3 terms)

Find equations of the line that is parallel to the z-axis and passes through the midpoint between the two points (0, −3, 7) and

tia_tia [17]

Answer:

$\vec{r}(t)=\left$

In parametric form:

$x=-1, y=\displaystyle\frac{1}{2}, z=4+t$

Step-by-step explanation:

We first find the mid point:

$\displaystyle\left(\frac{0+(-2)}{2},\frac{-3+4}{2},\frac{7+1}{2}\right)=\left(-1,\frac{1}{2},4\right)$

Then, a vector parallel to the z-axis is:

$\vec{v}=\left< 0,0,1 \right>$

Then remember the equation of a line passing through point $(x_o,y_o,z_o)$ and parallel to the vector $\vec{v}=\left$ is:

$\vec{r}(t)=\left+t\left$

So, in this problem we get:

$\vec{r}(t)=\left+t\left$

After combining the two vectors:

$\vec{r}(t)=\left$

In parametric form:

$x=-1, y=\displaystyle\frac{1}{2}, z=4+t$

For an independent-measures research study (i.e., independent measures t Test), the data show an 8-point difference between the

zloy xaker [14]

Answer:

C. 2

Step-by-step explanation:

Cohen's d is a parameter used to express the standardised difference between two means. It is defined as the difference between the means divided by the pooled standard deviation.

In this case, the difference between both means (M2-M1) is 8. As for the pooled standard deviation, simply take the square root of the given pooled variance:

$S=\sqrt{S^2}\\S=\sqrt{16} \\S= 4$

Therefore, the value of Cohen's d (d) is:

$d=\frac{M_{2} -M_{1}}{S} \\d=\frac{8}{4}\\d=2$
