Step-by-step explanation:

Hey!

I think there might be some confusion on the problem. Here's what I get:

Arranging in ascending order:

$71,\:79,\:83,\:85,\:86,\:88,\:89,\:90,\:93,\:93$

Since there are 10 terms, that is an even number. We will find the two numbers that are middlemost, and then divide them by two.

We see that 86 and 88 are the middlemost. 86 + 88 = 174

174 ÷ 2 = 87.

Thus, the median is $\boxed{87}$ .

Hope this clears up any confusion!

Hi Brainiac

y=3x-7

y=2x+1

We need to solve y=3x-7 for y

Now let's start by substitute 3x-7 for y in y=2x+1

y=2x+1

3x-7=2x=1

Now add -2x

3x-7-2x=2x+1-2x

x-7=1

Add 7

x-7+7=1+7

x=8

Our last step is to substitute 8 for x in y=3x-7

y=3x-7

y=(3)(8)-7

y= 24-7

y= 17

Answer : A

I hope that's help:)

An insufficient funds check was returned to your company. How does the bank treat this on your bank statement

Advocard [28]

A "bounced fund" or "bounced cheque" gets a fine for bank's account holder, so if someone gives you a cheque, you deposit it in your bank's account, and the bank tries to liquidate it and the other bank that's got the funds says, there isn't enough and therefore refuses to send anything, then your bank fines your account for the bouncing.

Depending on the bank could be more or less, in the US is more often than not about $20 or $25 for a bounced cheque.
