Answer: Lower = 1         Median = 2          Upper = 4

              Upper ≠ 1 so statement is false

<u>Step-by-step explanation:</u>

The Lower quartile (Q1) is the left side of the box.<em> I estimate it to be 1.</em>

The Median (Q2) is the line dividing the box.<em> I estimate it to be 2.</em>

The Upper quartile (Q3) is the right side of the box.<em> I estimate it to be 4.</em>

<em />

The upper quartile is the 75th percentile.  It is not 1 so the statement is false.

The annual expenditure of the US federal government is approximately 444 trillion dollars. If a one dollar bill is 0.00010.00010
Vsevolod [243]

Answer:

4*10^{7} meters.

Step-by-step explanation:

This question can be solved using a rule of three.

If a one dollar bill is 0.0001 meters thick.

So 1 dollar is 10^{-5}m tall.

How tall is 4 trillion one dollar bills?

1 trillion = 10^{12}

So 4 trillion = 4*10^{12}

Then

1 dollar - 10^{-5}m

4*10^{12} - xm

x = 4*10^{12}*10^{-5} = 4*10^{7}

The answer is 4*10^{7} meters.

Wang Yong owes the bank
dusya [7]

Given:

Wang Yong owes the bank $8500. He pays back a fixed amount each month. After 12 months, he still has to pay off $6460.

To Find:

The amount of money he pays the bank every month and how long it will take him to pay off the full debt.

Answer:

Wang Yong pays $170 each month, and doing so, it will take him a total time of 50 months to pay off the full debt.

Step-by-step explanation:

Wang Yong has borrows $8500 according to the question.

Say he pays the bank an amount of x every month, which is fixed. After 12 months, he still has to pay $6460.

In 12 months, he would have paid the bank 12x.

But $6460 is still left out of the original $8500.

This means,

8500-12x=6460\\\\12x=8500-6460\\\\12x=2040\\\\x=170

That is, Wang Yong pays the bank $170 every month.

Next, to calculate the amount of time it took Wang Yong to pay back his whole debt, we divide the total sum of money owed to the bank by the amount Wang Yong pays each month.

So, number of months = 8500 ÷ 170 = 50

That is, Wang Yong will pay off his debt 50 months after borrowing the money from the bank, provided he pays back $170 every month.

Number of pit bull dogs in a pound = P = 23

Number of chihuahuas dogs in a pound = C = 17
