Answer: The length of the line B'C" is 1 unit.

Step-by-step explanation:

Given: Triangle ABC is dilated by a scale factor of 0.5 with the origin as the center of dilation , resulting in the image Triangle A'B'C'.

If A (2,2), B= (4,3) and C=(6,3).

Distance between (a,b) and (c,d): D=\sqrt{(d-b)^2+(c-b)^2}

Then, BC =\sqrt{(3-3)^2+(6-4)^2}

\\\\=\sqrt{0+2^2}\\\\=\sqrt{4}\\\\=2\text{ units}

Length of image = scale factor x length in original figure

B'C' = 0.5 × BC

= 0.5 × 2

= 1 unit

Hence, the length of the line B'C" is 1 unit.

Viefleur [7K]
11.45

the 11 is ur whole number...it stays ur whole number
the 0.45 is ur fraction...and since the last number (5) is in the hundredths place, put it over 100
so u now have : 11 45/100 which reduces to 11 9/20 and if u need it in improper fraction form, it is 229/20

The correlation coefficient is used to determine: a. a specific value of the y-variable given a specific value of the x-variable
SSSSS [86.1K]

Answer:

c. the strength of the relationship between the x and y variables

Step-by-step explanation:

The correlation coefficient refers to the relationship between the two variables

Moreover, it has two mainly correlations i.e

Perfect positive correlation: In this, the  correlation coefficient is 1

And, the other is negative correlation: In this, the co

if the correlation coefficient is 1 we have a perfect positive correlation and if the correlation coefficient is -1 than it would be a negative correlation

It lies value between the  -1 and 1

hence, the correct option is c.
