Which two points should the line of best fit go through to best represent the data in the scatterplot?

Ilya [14]

Given : A graph with points (1, 3), (2, 7), (3, 8), (4, 11), (5, 12), (6, 13).

To find : From Which two points the line of best fit goes through

Solution:

(3, 8) & (5, 12) will be two points

as then line points will be

( 1 , 4 ) , ( 2, 6) , ( 3 , 8 ) , ( 4, 10) , (5 . 12) & ( 6 , 14)

(1, 3) will be below ( 1 , 4 )

(2 , 7) will be above ( 2 , 6)

( 3 , 8 ) will be on line

(4 , 11 ) will be above ( 4 , 10)

( 5 , 12 ) will be on line

( 6 , 13) will be below ( 6 , 14 )

(1, 3) & ( 6 , 13) two points are below line

(2 , 7) & (4 , 11 ) two points above line

Hence points are Equally scattered above & below line

Hence (3, 8) & (5, 12) will be two points on line of best fit

Hope it helpss !!

Three years ago, you purchased a stock at a price of $33.48. The stock paid annual dividends of $.60 per share. Today, the stock

mixas84 [53]

Answer:

10.51%

Step-by-step explanation:

Data provided in the question:

Period Initial value = $33.48

Period end value = $35.20

Annual dividend paid = $0.60

Total time = 3 years

Therefore,

the total dividend paid i.e the income = 3 × $0.60 = $1.80

Now,

The holding period is given as:

$= \frac{ \textup{Income + end period value - initial period value }}{\textup{initial period value}}\times100\%$

= $\frac{ \textup{1.80 + 35.20 - 33.48}}{\textup{33.48}}\times100\%$

= $\frac{ \textup{3.52}}{\textup{33.48}}\times100\%$

= 10.51%

vitfil [10]

Here are 3 equivalent expressions that would represent the total number of pencils and pens in Karen's backpack.

1. 4p + 6

2. p+ p + p + p + 6

3. 6 + 4(p)

Each of these has four groups of p +6 represented.
