A track and field coach wants to study the average 100-meter dash time of his team. A random selection of half the team has a mean time of 13 seconds. Is this mean considered a sample mean or a population mean, and which symbol would be used to denote it?

answer: -1

step-by-step explanation:

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:

do it yourself this is easy

step-by-step explanation:

the answer to this is:

factor 2x2+16x+24

2x2+16x+24

=2(x+2)(x+6)

answer:

2(x+2)(x+6)

hope this hmu if needed
