A technician is testing light bulbs to determine the number of defective bulbs. The technician records the table below to show t
Kruka [31]

Answer:

The ratio of the number of bulbs tested to defective bulbs is always 14 to 1.

<u><em>What is the unitary method?</em></u>

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

We generally expect industrial processes to produce defects at about the same rate, the proportion of the defective product is generally considered to be a remain constant.

Here, the proportion of defective bulbs is:

1/14 = 2/28 = 6/84

So, it will be 24/336.

The ratio of the number of bulbs tested to defective bulbs is expected to remain constant at about 14.

Ibuki factored 12x^7as (4x^3)(3x^4)
Marina86 [1]

Answer:

Both are correct.

Step-by-step explanation:

The key understanding here is that you can factor a monomial in many different ways!

To check if any of the factorizations is correct, we can multiply the factors and see if their product is really 12x^712x

7

12, x, start superscript, 7, end superscript.

Hint #22 / 4

\begin{aligned} (\blueD{4}\maroonD{x^3})(\blueD{3}\maroonD{x^4})&=(\blueD{4})(\blueD{3})(\maroonD{x^3})(\maroonD{x^4}) \\\\ &=\blueD{12}\maroonD{x^7} \end{aligned}

(4x

3

)(3x

4

)

​

 

=(4)(3)(x

3

)(x

4

)

=12x

7

​

So Ibuki is correct!

Hint #33 / 4

\begin{aligned} (\blueD{2}\maroonD{x^6})(\blueD{6}\maroonD{x})&=(\blueD{2})(\blueD{6})(\maroonD{x^6})(\maroonD{x}) \\\\ &=\blueD{12}\maroonD{x^7} \end{aligned}

(2x

6

)(6x)

​

 

=(2)(6)(x

6

)(x)

=12x

7

​

So Melodie is also correct!

Both Ibuki and Melodie are correct.
