8 0

The formula of a perimeter of a rectangle:

P=2(l+w)

l - length

w - width

We have:

l=2x-3,\ w=x+4

Substitute:

P=2(2x-3+x+4)=2(3x+1)\\\\_{\text{use distributive property}}\\\\=(2)(3x)+(2)(1)=\boxed{6x+2}

Which is greater? 79.47mi,54.28mi,65.5mi,98.43mi
Blababa [14]

Answer:

The greater value of the  given set is 98.43.

Explanation:

Here the units of the distance given for all the data is miles(mi).

So, the greater value is that value which has higher magnitude.

Values are 79.47,54.28,65.5 and 98.43

Values in their increasing order is given by

             54.28 < 65.5 < 79.47 < 98.43

 Values in their decreasing order is given by

             98.43 > 79.47 > 65.5 > 54.28

So, the greater value of the  given set is 98.43.

You use a line of best fit for a set of data to make a prediction about an unknown value. The correlation coefficient for your d
Trava [24]

Answer:

Following are the solution to this question:

Step-by-step explanation:

For this set, the correlation coefficient is = -0.015.

It shows that financial variables have trust issues. Once a price rises, the other one is decreasing the value of -0,015 shows, that there are several fewer associations in the set of data among x and y and between y values. This interaction also can range between -1 to 1, to 0 being completely unrelated. But you'd never be sure, in this situation, 0.015 is very similar to 0.

It means that your prediction is nothing better than just a wild choice. Its odds of an estimated value being relatively close to the actual result are therefore much smaller as the points are it's hardly the best match.
