The t-value measures the size of the difference relative to the variation in your sample data. Put another way, T is simply the calculated difference represented in units of standard error. The greater the magnitude of T, the greater the evidence against the null hypothesis.

Answer:

t = 41

Step-by-step explanation:

The figure shows a polygon with one <u>exterior</u> angle at each vertex.  In any polygon, the sum of those angle measures is 360 degrees.

Setup the sum and set it equal to 360.

3t + 2t + 61 + 52 + 42 = 360

Combine like terms.

5t + 155 = 360

Subtract 155.

5t = 205

Divide by 5.

t = 41

Write the point slope form of the line that passes through (-8,2) and is parallel to a line with a slope of -8. include all your
Juli2301 [7.4K]

<u>Answer: </u>

The point slope form of the line that passes through (-8,2) and is parallel to a line with a slope of -8 is 8x + y + 62 = 0

<u>Solution: </u>

The point slope form of the line that passes through the points \left(x_{1} y_{1}\right) and parallel to the line with slope “m” is given as  

y-y_{1}=m\left(x-x_{1}\right) --- eqn 1

Where “m” is the slope of the line.  

x_{1} \text { and } y_{1} are the points that passes through the line.

From question, given that slope “m” = -8

Given that the line passes through the points (-8,2).Hence we get

x_{1}=-8 ; y_{1}=2

By substituting the values in eqn 1, we get the point slope form of the line which is parallel to the line having slope -8 can be found out.

y-2=-8(x-(-8))

On simplifying we get

y – 2 = -8(x +8)

y – 2 = -8x -64

y – 2 +8x +64 = 0

8x + y +62 = 0

Hence the point slope form of given line is 8x + y +62 = 0

For the following​ equation, find three ordered pair solutions by completing the table. Then use the ordered pairs to graph the
Viktor [21]

The graph of the linear equation can be seen in the image below.

<h3>How to complete the table?</h3>

Here we have the linear equation:

y = -4x + 8

And we want to find 3 ordered pairs, to do so, we need to evaluate x in different values.

if x = 0 then:

y = -4*0 + 8 = 8

So we have the ordered pair (0, 8).

if x = 1 then:

y = -4*1 + 8 = 4

Then we have the ordered pair (1, 4)

If x = 2 then:

y = -4*2 + 8 = 0

Then we have the ordered pair (2, 0).

Now that we have these 3 ordered pairs, we can graph them in a coordinate axis and then connect them with a line, we will get something like the graph below.

That is the graph of our linear equation:

A particle moves along line segments from the origin to the points (3, 0, 0), (3, 3, 1), (0, 3, 1), and back to the origin under
Ierofanga [76]

Answer:

[8i + 54j + 72k] joules per newton metre square.

Step-by-step explanation:

F(x,y,z) = z2i + 3xyj + 3y2k

F(3,0,0) = 0

F(3,3,1) = 1(2i) + 3(3)(3)j + 3(3)(2k)

= 2i + 27j + 18k

F(0,3,1) = 1(2i) + 3(0)(3)j + 3(3)(2k)

= 2i + 18k

The sum = [4i + 27j + 36k]

Since the particle moves back to the origin, we multiply the above Work Done by 2:

[8i + 54j + 72k]

And since work done is the product of Force and Distance, the S.I. unit is Joules/newton metre square
