You ALWAYS remove parentheses first.

That gives you [ 1/4 a⁴ b⁻² ] in the denominator, and then
you can start dividing the numerator and denominator by
their common factors ("canceling").

I think the answer to that might be 1/2 or .5ab^3 because I multiplied the bottom part -2*-2 which is 4ab^4 then the top part is 2ab -3+2= 2ab^-1 then divide 2/4 and subtract -1-4 so it's = 1/2 or .5ab^3

Using the data: 2, 2, 3, 3, 3, 4, 5, 6, 6, 19<br><br> What is Q1 and Q3

Anettt [7]

Answer:

$Q_1=2$

$Q_3=6$

Step-by-step explanation:

Notice that we already have the data sorted from least to greatest.

Now to find Q1 and Q3 we can use the following formulas

For a set of data ordered from least to greatest of the form $X_1, X_2, ..., X_n$

Where n is the total number of data

$Q_1=X_{\frac{1}{4}(n+1)}$

In this case $n=10$

So:

$Q_1=X_{\frac{1}{4}(10+1)}$

$Q_1=X_{2.75}$

Round the nearest whole and get:

$Q_1=X_{3}$

$Q_1=3$

For Q3 we have:

$Q_3=X_{\frac{3}{4}(n+1)}$

$Q_3=X_{\frac{3}{4}(10+1)}$

$Q_3=X_{8.25}$

Round the nearest whole and get:

$Q_3=X_{8}$

$Q_3=6$
