If the equation of a circle is (x + 5)2 + (y - 7)2 = 36, its center point is

The center of the given circle is (-5,7)

Step-by-step explanation:

step1:-

The Equation of the circle having center and radius

In this circle form the center is (h,k) and r be a radius

step2:-

The given equation of the circle is (x+5)^2+(y-7)^2=36

comparing the general form of circle equation is

so the center of the given circle is (h,k) = (-5,7)

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
