Point Q is plotted on the coordinate grid. Point P is at (10, −20). Point R is vertically above point Q. It is at the same dista
bixtya [17]

Answer:

Point R is at (−20, 10), a distance of 30 units from point Q

Step-by-step explanation:

Q has coordinates (-20,-20).

P has coordinates (10,-20)

Since point R is vertically above point Q, it will have the same x-coordinate as Q.

Let R have coordinates (-20,y).

It was given that;

|RQ|=|PQ|

\Rightarrow |y--20|=|10--20|

\Rightarrow y+20=10+20

\Rightarrow y=10+20-20

\Rightarrow y=10.

The coordinates of R are (-20,10).

The dstance from Q is 30 units.

If a particular set of data is approximately normally distributed, we would find that approximately A) 2 of every 3 observations
Kryger [21]

Answer:

A) No

B) No

C) Yes

Step-by-step explanation:

A)  2 out of three observations is equal to

2/3  = 0.67    or  67 %

We know tha the interval

[μ  -  σ/2 ,  μ + σ/2]  is approximately 68.3 % of the values

Therefore 2 out of 3 would not fall in that interval

B)

4 out of  5   is  4/5    = 0,8     or 80 %  If we  examine the interval

[μ  -  σ ,  μ + σ ]   which is approximately 95. Then value 4/5  ( 0,8)

Therefore 0,8 is out of the interval

C) 19/20 = 0,95     or 95 % is almost exact the value for the interval

[μ  -  1.5σ ,  μ + 1.5σ ]  That value is inside  μ - 2σ , μ + 2
