decrease your scale values
B.
increase your scale values
C.
plot more points
D.
plot fewer points
Answer:
Option: B is correct.
B) Increase your scale values.
Step-by-step explanation:
When creating a scatterplot, if the points are too close together to see the relationship,then we must increase the scale value of our graph .
" Because by doing so the point will seem to be farther and we could see the clear relationship between the points and hence it will not create any confusion regarding the visual of the points and hence easily the inference could be drawn"
Hence, option: B is true.
(B) Increase the scale value)
Answer:
A
Step-by-step explanation:
a. (x+2)^2=20
b. (x+1)^2=23
c. (x+1)^2=20
d. (x+2)^2=23
Answer:
c.
Step-by-step explanation:
Since, for getting a perfect square on the left side of a quadratic equation we follow the following steps,
Step 1 : Make 1 as the coefficient of .
Step 2 : Add both side the square of a number which is half of the x's coefficient.
Given equation,
-----(1)
Here, the coefficient of is already one.
And, the middle term is 2,
Half of 2 is 1
Also, 1² = 1
Thus, add 1 on both sides of equation (1),
( Because (a+b)² = a² + 2ab + b² )
⇒ Option C is correct.
