Answer:

The correct answer is REPLICATION

Step-by-step explanation:

Replication is important for the support of the study. It is when a procedure repeats using the same methods, different subjects and experiments. It also involves the application of the theory of the study in new situations in order to generalize it. Replication assurances the validation and reliable of the results, generalize them

8) Find x if m m<br> i’m
Kaylis [27]

Answer:

7

Step-by-step explanation:

Remark

The two angles with x in their numerical value are added to get 108

Solution

10x + 2 + 4x + 8 = 108                Collect like terms

14x + 10 = 108                             Subtract l0 from both sides.

14x + 10 -10 = 108 - 10                Collect like terms

14x = 98                                      Divide by 14

x = 98/14

x = 7

Hi! I was wondering if you could help with this question please :)​
Makovka662 [10]

Answer:

R=\frac{QJ}{I^2t}

Step-by-step explanation:

So we have the equation:

Q=\frac{I^2Rt}{J}

And we want to solve for R.

First, let's multiply both sides by J to remove the fraction on the right. So:

(J)Q=(J)\frac{I^2Rt}{J}

Simplify the right:

JQ=I^2Rt

We can rewrite our equation as:

JQ=R(I^2t)

So, to isolate the R variable, divide both sides by I²t:

\frac{JQ}{I^2t}=\frac{R(I^2t)}{I^2t}

The right side cancels, so:

R=\frac{QJ}{I^2t}

And we are done!

Which points lie on the line that passes through point P and is parallel to the given line? Check all that apply.
11111nata11111 [884]

Answer:

(-1, 3), (-2, 2) and (-5, -1) lie on the line.

Step-by-step explanation:

Let the equation of the line which is parallel to the given line is y = mx + c

Here m is the slope of line similar to the line given = (y - y')/(x - x')

Here (x, y) and (x', y') are (4, 2) and (-2, -4)

then m = (2+4)/(4+2) = 6/6 = 1

Now the equation of the line will be y = x + c

This line passes through point P(0, 4)

4 = 1×0 + c

c = 4

Therefore equation of the line will be

y = x + 4

Now we check for each point given in the question whether it lies on the line or not.

For (-4, 2)

y = (-4) + 4 = 0

Hence not lies on the line.

For (-1, 3)

y = (-1) + 4 = -1 +4 = 3

Hence (-1,3) lies on the line.

For (-2, 2)

y = (-2) + 4 = -2 + 4 = 2

Hence (-2, 2) lies on the line.

For (4, 2)

y = 4 + 4 = 8

Hence (4, 2) lies on the line.

For (-5, -1)

y = -5 + 4 = -1

Hence (-5, -1) lies on the line.

Therefore (-1, 3),(-2, 2) and (-5, -1) lie on the line.
