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.

Simplify completely quantity of x squared plus 7 x minus 30 all over quantity of x plus 10. x2 + 4 x2 ? 4 x ? 3 x + 3
GalinKa [24]

This looks like: \frac{x^2+7x-30}{x+10}

To solve this problem, you'll want to use the AC method to factor x^2+7x-30.

After factoring your expression will look like this:

\frac{(x-3)(x+10)}{x+10}

Cancel out the x+10 because they are common factors, so you are just left with the simple x-3.

Answer is:

x - 3
