The values in a dataset are 3.5, 2.5, 2.5, 3.5, and 3.0. If Xbar (sample mean) = sigma X / n, what is the mean for the sample?

RideAnS [48]

Answer:

$\bar x = 3.0$

Step-by-step explanation:

Given

$x: 3.5, 2.5, 2.5, 3.5, 3.0$

Required

The sample mean

This is calculated using:

$\bar x = \frac{\sum x}{n}$

So, we have:

$\bar x = \frac{3.5+ 2.5+ 2.5+ 3.5+ 3.0}{5}$

$\bar x = \frac{15.0}{5}$

$\bar x = 3.0$

Using the transformation T: (x,y) —> (x+2, y+1), find the distance CB

pshichka [43]

Answer:

The distance between CB is $\sqrt[]{10}$

Step-by-step explanation:

Recall that the transformation T consists of a translation of 2 units to the right and 1 unit up. Then, T preserves distances(which means that it keeps distances between points the same as before applying the transformation). Then, distance CB is the sames as distance C'B'. We will use the distance formula: if we have points (x,y), (z,w) then the distance between them is given by

$\sqrt[]{(x-z)^2+(y-w)^2}$

In our case we have that C'=(0,3), B'=(3,4). Then, the distance between them is

$\sqrt[]{(3-0)^2+(4-3)^2}= \sqrt[]{10}$

Answer:

64 bags

Step-by-step explanation:

number of bags sold by Takis Scorpion BBQ = x

Number of bags sold by Takis Valcano Quesco = 3x - 6

the total number of bags = x + ( 3x - 6 )

x + 3x - 6 = 250

therefore, 4x - 6 = 250

4x = 250 + 6

4x = 256

dividing through by 4

x = 64
