3 0

Answer:

-(-3) ± √(-3)^2 - 4(2)(-5) / 2(2)  (the last choice).

Step-by-step explanation:

Im ignoring the 2^2 in the equation

The equation transforms to

2x^2 - 3x - 5 = 0    (standard form)

So x = -(-3) ± √(-3)^2 - 4(2)(-5) / 2(2)

A battery manufacturer randomly tests 500 batteries and finds that 3 are defective.
ale4655 [162]
To find this answer, we must first find the percentage of batteries that are defective. We can do this by dividing 3 by 500.

3 / 500 = 0.006

So our percentage of defective batteries is 0.6%.

Now, to find out how many defective batteries would be in a batch of 12000, we just need to multiply the constant (percentage of defective batteries) by the amount in the new batch.

12000 * 0.006 = 72

In a shipment of 12,000 batteries, 72 will be defective, so the correct answer choice would be B.
Hope that helped =)

Pls helppppp last questionnnnn
zzz [600]

Answer:

G. \frac{3.2}{2} = \frac{a}{8}

Step-by-step explanation:

Given that figure I and figure II are similar, it follows that the ratio of their corresponding side lengths are equal and the same.

Thus:

\frac{3.2}{2} = \frac{a}{8} = \frac{8}{5} = \frac{6.4}{b}

Therefore, the proportion that must be true is:

✔️\frac{3.2}{2} = \frac{a}{8}
