Consider the following data and corresponding weights.

Sergio [31]

Answer:

a) tex] \bar X = \frac{\sum_{i=1}^n X_i}{n}[/tex]

And replacing we got:

$\bar X= \frac{3.2+2.0+2.5+5.0}{4}=3.175$

b) $\bar X = \frac{\sum_{i=1}^n w_i x_i}{\sum_{i=1}^n w_i}$

And replacing we got:

$\bar X= \frac{3.2*6+2.0*3+2.5*2+5.0*8}{6+3+2+8}=\frac{70.2}{19}=3.695$

Step-by-step explanation:

Part a

For this case we can calculate the the unweigthed with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

And replacing we got:

$\bar X= \frac{3.2+2.0+2.5+5.0}{4}=3.175$

Part b

For this case the weigthed mena is given :

$\bar X = \frac{\sum_{i=1}^n w_i x_i}{\sum_{i=1}^n w_i}$

And replacing we got:

$\bar X= \frac{3.2*6+2.0*3+2.5*2+5.0*8}{6+3+2+8}=\frac{70.2}{19}=3.695$

4. (168/54=3.1111111) So there wouldn't be enough room for all on 3, so you would have to take 4.

All I know it’s not D and i’m super confused and I just want to go to bed

Harlamova29_29 [7]

Answer:

Step-by-step explanation:

Before graphing this equation we first need to isolate y on one side like so...

y + 2 = 3(x+1) ... distribute the 3 to both values inside the parenthesis

y + 2 = 3x + 3 ... subtract 2 on both sides

y = 3x + 1

Now that we have the y variable isolated we see that the slope of the function is 3, meaning that for every 1 unit right the line needs to move 3 units up. We also have the value where the line needs to cross the y-axis and that is 1. Using this information we see that the correct graph is C.
