The definition of a Scale Drawing is- A drawing that shows a real object with accurate sizes reduced or enlarged by a certain amount (called the scale). The scale is shown as the length in the drawing, then a colon (":"), then the matching length on the real thing.
Well an example would be- Write the scale of the drawing, 1 cm = 1.5 m, as . Then write a proportion in which each ratio compares centimeters to meters. Let n represent the actual length of the boat. The actual length of the boat is 4.5 m. explaining is a little hard, but u can look up video examples to help u understand better

Luna had $50 dollars when she got to the carnival. After riding 12 rides she had $26 dollars left. What was the price of each ri

Alexeev081 [22]

$50 minus $24 equals $26 which means that she spent a total amount of $24 on rides 24 divided by 12 equals 2 which means each ride costs $2
We could represent the equation this way I guess ?
50 - ? = 26
?/12 = ?
Or maybe you could replace the question marks with an x

The tables below show four sets of data:

vovangra [49]

Answer:

Hence, the set that represent a negative linear association between x and y is:

Set A.

Step-by-step explanation:

We are given 4 sets of data as:

Set A

x 1 2 3 4 5 6 7 8 9

y 10 9 8 7 6 5 4 3 2

Set B

x 1 2 3 4 5 6 7 8 9

y 3 4 5 6 7 8 9 10 11

Set C

x 1 2 3 4 5 6 7 8 9

y 8 6 5 4 3.5 3 2.5 2 2

Set D

x 1 2 3 4 5 6 7 8 9

y 1 2.5 2.5 3 4 5 6 8 9

We are asked to determine the set which represent negative linear association between x and y?

Clearly in Set B and Set D the values of y keeps on increasing as the value of x increases; hence they both represent a positive linear association between x and y.
In set C the relationship is non-linear though it is negative.
Clearly in Set A we could see that the the y is related to x as:

y=11-x or y= -x+11.

Hence, clearly we could see that the relationship is linear and also negative as the value of y keeps on decreasing with increasing x.

Hence, the set that represent a negative linear association between x and y is:

Set A.
