Answer:

C, B, A

Step-by-step explanation:

The sides in order from shortest to longest are ...

AB = m-2

AC = m

BC = m+4

The angles opposite these sides will be in order, smallest to largest. The angle opposite is the one whose letter is not in the line segment name.

Which of the following describes the probability distribution below?

Serhud [2]

Answer:

B. Median is greater than the mean and the majority of data points are to the right of the mean.

Step-by-step explanation:

Mean = sum(x × p(x))

= (1×0.1)+(2×0.15)+(3×0.2)+(4×0.45)+(5×0.1)

= 3.3

Probability of more than 3.3 is:

0.45 + 0.1 = 0.55 > 0.5

A group of hikers walks 3 miles east and then 1 mile north. After taking a break, they then hike 4 miles east to their final des

geniusboy [140]

Answer:

The vector that describes their hike from their starting position to their final destination is $\vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi]$ .

Step-by-step explanation:

In this problem we assume that orthogonal axes coincide with the north and east. We proceed to translate each sentence from statement into vectorial equations:

(i) A group of hikers walks 3 miles east and then 1 mile north:

$\vec r_{A} = 3\,\hat{i}+1\,\hat{j}\,\,\,[mi]$

(ii) After taking a break, they then hike 4 miles east to their final destination:

$\vec r_{B} = 4\,\hat{i}\,\,\,[mi]$

The vector that describes their hike from their starting position to their final destination is the sum of the vectors deducted above. That is:

$\vec r = \vec r_{A}+\vec r_{B}$ (1)

$\vec r = (3\,\hat{i}+1\,\hat{j})+4\,\hat{i}\,\,\,[mi]$

$\vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi]$

The vector that describes their hike from their starting position to their final destination is $\vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi]$ .
