lawyer [7]

Answer:

c = -5

d = -10

Step-by-step explanation:

A biologist is tracking a bird when it was at A.

Coordinates of point A are (2, 4).

This bird moves from point A to point B.

Coordinates of the point B are (-3, -6).

Vector form of vector represented by $\overrightarrow{AB}=$

By substituting the coordinates of points A and B,

$\overrightarrow{AB}=$

= < -5, -10 >

$\overrightarrow{AB}=\binom{-5}{-10}$

By comparing it with the vector form of [cd]

c = -5

d = -10

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:

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

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

$\bar x = 3.0$
