-4-5= -9

4- -2=6

You divide and u get 1.5 which is also known as 1 and 1/2

timama [110]

Step-by-step explanation:

Unfortunately you didn’t provide the expressions to chose from

however, we can write :

(5g+3h+4) •2 = 2*5g + 2*3h + 2*4  (using distributive property)

                     = 10g + 6h + 8.

For a repeated-measures study comparing two treatments with 12 scores in each treatment, what is the df value for the t statisti
marishachu [46]

The degree of freedom for t statistic is 11.

According to the given question.

For a repeated-measure study, comparing two treatments with 12 scores in each treatment .

So, we can say that sample size, n = 12.

We know that, when you have a sample and estimate the mean, we have

n – 1 degrees of freedom, where n is the sample size.

Therefore,

The degree of freedom for the given sample test will be

d.f = n -1

⇒ d.f = 12 - 1

⇒ d.f = 11

Hence, the degree of freedom for t statistic is 11.

In the form of the matrice, how do you work out the following simultaneous equation?
lapo4ka [179]
\left[\begin{array}{ccc}1&3&7\\1&1&1\end{array}\right]
multiply 2nd row by -1 and add to first row
\left[\begin{array}{ccc}0&2&6\\1&1&1\end{array}\right]
divide the 1st row by 2
\left[\begin{array}{ccc}0&1&3\\1&1&1\end{array}\right]
multiply the first row by -1 and add to 2nd row
\left[\begin{array}{ccc}0&1&3\\1&0&-2\end{array}\right]

now we know
y+3=0
x-2=0

therefor
y=-3
x=2

Graph x≥−1, plz amswer. from khan
Mrrafil [7]

Draw a number line. Plot -1 on the number line and make this a filled in circle. Shade to the right of the filled in circle to indicate the set of values x such that x \ge -1

So x could be -1 or it could be larger. The fact that x = -1 is possible is why we have a closed or filled in circle (instead of an open hole) at this endpoint.
