7 0

Answer:

B."5, -3, -4, 1, -1, 6, -4"

Step-by-step explanation:

We are given that

13,5,4,9,7,14,4

We have to find the deviation.

Mean=\frac{sum\;of\;data}{total\;number\;of\;data}

Using the formula

Mean,\mu=\frac{13+5+4+9+7+14+4}{7}

Mean,\mu=\frac{56}{7}=8

Deviation=x_i-\mu

         x_i-\mu

13          5

5           -3

4           - 4

9            1

7             -1

14            6

4            - 4

Hence, option  B is correct.

A mountain climber explored a cliff that is 225 yards high in 5 equal descents. How many yards was one descent?
Montano1993 [528]
So if the cliff is 225 yard in height and he want to make it down in 5 equall decents
that means that each dessent is 1/5 of 225 or 225/5
225=125 times 5 so if you divied 225 by 5 then you get 125
so each dessent is 125 yards

Find so that the distance between (−2,3) and (,1) is √13
belka [17]

The distance between (-2, 3) and (-5, 1) is √13.

or, the distance between (-2, 3) and (1, 1) is √13.

We know that the length of the line segment connecting any two points represents the distance between them. There is just one line that connects the two points. Therefore, by measuring the length of the line segment that connects the two points, the distance between them can be determined. If (a, b) and (c, d) be two points, then the distance between them is \sqrt[]{(b - a)^{2} +(d- c)^{2} }.

Here, one point is (-2, 3).

Let the other point be (x, 1).

Given that the distance is √13.

Now, \sqrt[]{(x - (-2))^{2} +(1 - 3)^{2} } = \sqrt{13}  

i.e. \sqrt[]{(x + 2)^{2} +( - 2)^{2} } =\sqrt{13}

i.e. \sqrt[]{x^{2}+4x +4 +4 }=\sqrt{13}

i.e. x^{2}+4x +8 =13

i.e. x^{2}+4x + 8- 13=0

i.e.x^{2}+4x -5=0

i.e. x^{2} +5x - x -5=0

i.e. x(x+5)-1(x+5)=0

i.e. (x+5)(x-1)=0

i.e. x=-5,1

So, the point is either (-5, 1) or (1, 1).

Therefore, the required point is either (-5, 1) or (1, 1).

i.e. the distance between (-2, 3) and (-5, 1) is √13.

or, the distance between (-2, 3) and (1, 1) is √13.
