With math i have the answer which is ''c'' just need an explanation on how i got the answer.
a worker takes a random sample of 200 bolts and finds that 30 of them are either too long or too short, thus making them unusable. estimate the number of unusable bolts in a production of 17,000 bolts.
a. 2,260 bolts
b. 2,140 bolts
c. 2,550 bolts
d. 1,610 bolts
i know the answer is ''c'' i just need an explanation of how to get the answer.

C . 2,550 bolts. lol

Step-by-step explanation:

A simple technique to answer a question like this is to

Step 1: multiply 30 by 17000 = 510000

Step 2: divide 510000 by 200 = 2550

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
