chubhunter [2.5K]

Answer:

35

The standard equation of a circle with centre (xc,yc) and radius R is given by

(x-x_c)^2+(y-y_c)^2=R^2

Substituting
centre (xc,yc) = (4,-3)
R=2.5

The equation is therefore

(x-x_c)^2+(y-y_c)^2=R^2
(x-4)^2+(y-(-3))^2=2.5^2
(x-4)^2+(y+3)^2=2.5^2  or
(x-4)^2+(y+3)^2=6.25

So, I need some help with these scatter plot questions. (basically free points because these might be easy for you!) (20 points)
nlexa [21]

Hello,

I have a graphing calculator so this will be easy for me to answer and explain how to figure these out. Here we go!

1. Well on a Ti - 84 plus calculator it says graph then you put in thee equations for each and C and D are already incorrect cause they go straight up and B is incorrect because it is a straight line on the top going straight. In this case your looking for a line that goes through the dots. And the answer would be A) Y = 1/2x + 7.

2. B) Then umber of accidents were reduced by 0.67 per month for every additional driver in the program.

3. Key: Y means yes N means no. Plot A had 1 disease present and 2 not present. Plot B has 3 diseases present and 1 disease not present.

4. Category A had 36 groups in group 1. and Category B had 12 groups in group 1. Easy!

Please mark Brainliest!

Hope I Helped!

Have a fantastic Day!
