What is the standart dievation of 63 and 37 and what is the standart dievation of 88 and 112 this is a sample not a population

hello that is a hard question but the answer is your face

im so sorry about the kid that said that. that was mean

Step-by-step explanation:

x = # of weeks

y = total amount of money

Your savings account: $122 + $12x = y

Your friend's savings account: $92 + $17x = y

As the question suggests, we need to set both equations equal to each other.

$122 + $12x = $92 + $17x

Subtract $92 from both sides and subtract $12x from both sides.

$30 = $5x

Divide both sides by $5

6 = x

It will take 6 weeks for you and your friend to have the same balance.
