Does a trend line always pass through every point on a scatter plot?
forsale [732]
No, it does not and it's not supposed to.  A trend line is drawn to go through in the best way possible, to go through the "center" of the points as best as it can.  It may hit some of the points, but not all of them.  Generally, the idea is to try to get the trend line to have as many points "above" it as it does "below" it to say you've gone through them evenly.

Svetlanka [38]

Answer:

A=28.13 Sq Ft

Step-by-step explanation:

Given that the length of the garden = 4.5 ft

Breadth of the garden = 6.25 ft

Area is given by the formula

A=length x breadth

A=4.5 x 6.25 sq ft

A= 28.125 sq ft

Here if we round the area to the nearest hundredth, the area will be

A=28.13 Sq Ft

Two friends, Alejandro and Mia, agreed to split the check at a restaurant. Alejandro ordered $12 worth of food and Mia ordered $
kvasek [131]

Cost of Alejandro's food = $12

Tip paid by Alejandro = 20% of his bill = 20% of 12 = 2.4

Cost of Mia's food = $18

Tip paid by Mia = 15% of his bill = 15% of 18 = 2.7

Total Tip Paid = 2.4+2.7 = 5.1

Total Check Amount = 12 + 18 = 30

Total tip paid by Alejandro and Mia is r% of the total check amount.

So, we need to determine what % of 30 is equal to 5.1%

⇒ r% × 30 = 5.1

⇒ r% = 5.1 / 30

⇒ r% = 17%

Hence, r is 17%

Which equations have the same value as 3/5 (30x-15)=72 select 3
const2013 [10]

Answer:

x=4.5

Step-by-step explanation:

Given the equation  \frac{3}{5}(30x-15)=72, we simplify as:

\frac{3}{5}(30x-15)=72\\\\18x-9=72

#We further simplify as multiples of 9(divide by 9 to solve for x):

18x-9=72\\\\2x-1=8\\\\2x=9\\\\x=4.5

Hence, from our simplification  the equation has the same value as x=4.5
