Maude - 225 albums, 135 heavy metal, 135/225 = 0.6 = probability of listening to heavy metal

Claude - 420 albums, 270 heavy metal, 270/420 = <span>0.64 (2 DP) = </span><span>probability of listening to heavy metal

Assuming the albums are picked randomly ... Claude has the highest probability of listening to heavy metal at 0.64 (2 DP), appose to Maude whose probability is less at 0.6.</span>

In circle D, if the measure of arc Gec is 230 , what is the measure of minor arc GFC
BabaBlast [244]

Answer:

The measure of minor arc GFC is 130\°

Step-by-step explanation:

we know that

In a circle the sum of the major arc plus the minor arc is equal to 360 degrees

see the attached figure to better understand the problem

Let

x------> the major arc GEC

y-----> the minor arc GFC

so

x+y=360\°

we have

x=230\°

substitute in the equation and solve for y

230\°+y=360\°

y=360\°-230\°=130\°

The equation of a given circle in general form is x^2+y^2-8x+12y+27=0. Write the equation in standard form, (x-h)^2+(y-k)^2=r^2,
umka2103 [35]

Answer:

(x - 4)² + (y + 6)² = 5²

Step-by-step explanation:

rearrange the general equation as follows

collect the terms in x and y together and place the constant on the right side

x² - 8x + y² + 12y = - 27

add (half the coefficient of the x/y term)² to both sides

x² + 2(- 4)x + y² + 2(6)y = - 27

(x - 4)² + 16 + (y + 6)² + 36 = - 27 + 16 + 36

(x - 4)² + (y + 6)² = 25

(x - 4)² + (y + 6)² = 5² ← in standard form
