Answer:

Answered

Step-by-step explanation:

Precision is how repeatable a result. An example how close the second arrow is to the first arrow.

Whereas Accuracy is how close a value with the true value. An example is how close an arrow gets to the bull's-eye center( true value).  

So, these are the most appropriate definitions of Accuracy and  precision.

The perimeters of the rectangle shown are equal. what is the perimeter of each rectangle.​
Svetradugi [14.3K]

Answer:

3.2 units

Step-by-step explanation:

Since the perimeters of the rectangles are equal:

n + n + 0.6 = n +0.1 + 2n

2n + 0.6 = 3n + 0.1

0.5 = n

Left Rectangle:

2 (0.5 + 0.5 + 0.6) = 3.2 units

Since they have the same perimeter, the rectangle on the right also has a perimeter of 3.2 units.

Solve for x: (x+a)(x-b) = x^2 -1 <br><br> How do I solve this ?
Sveta_85 [38]

You must factor.

x^2-1=(x+1)(x-1)

The factored form is equal to the assigned form.

(x+1)(x-1)=(x+a)(x-b)

Values a, b correspond to the factored 1, -1.

Value of x however remains unknown. But we can change that.

Given factored result,

(x+1)(x-1)

We can set expression equal to 0 then find such x that when added with number a or b results with 0.

(x+1)(x-1)=0

Hence x has 2 solutions.

x+1=0\Rightarrow\boxed{x_1=-1} \\x-1=0\Rightarrow\boxed{x_2=1}

Hope this helps.

Alex_Xolod [135]

Answer:

I assum you me (5,6) (25,30)

m= \frac{6}{5} or m= 1.2

Step-by-step explanation:

You can find slope by using this formula: m= \frac{y2-y1}{x2-x1}

  • Subtract the numbers : \frac{24}{20}
  • Reduce the fraction : \frac{6}{5}
