Answer:

3/28.

Step-by-step explanation:

Total of 8 balls in the jar.

Prob (first one not green (= that its red) = 3/8

Prob ( Second one is also red) = 2/7.

So probability that both are not green = 3/8 * 2/7

= 6/56

= 3/28.

The intersecting chords theorem states we can calculate the angle measure by... *
monitta

Answer:

A. Adding the values of the intercepted arcs and that is equal to twice the angle measure

Step-by-step explanation:

The intersecting chords theorem states that when four line segments are formed by two chords intersecting in a circle, the product of the two line segments on one chord is equal to the product of the two line segments on the other chord

The angles of intersecting chords theorem states that the angles formed by the intersecting chords one half the sum of the arcs intercepted by the chords

In the diagram attached, we have;

∠x = ∠y + ∠z

m\widehat{DHE} = 2·∠z, m\widehat{CIF} = 2·∠y

∴ ∠x = (1/2) × m\widehat{DHE} + m\widehat{CIF}

m\widehat{DHE} + m\widehat{CIF} = 2 × ∠x

The correct option is therefore adding the values of the intercepted arcs and that is equal to twice the angle measure.

Answer:

(5y-2)x(2x+5)

Step by step explanation:

10xy-4x+25y-10

Factor out 2x from the expression

2x*(5y-2)+25y-10

Factor our 5 from the expression

2x*(5y-2)+5(5y-2)

Factor out 5y-2 from the expression

(5y-2)x(2x+5)

How does 2 relate to 3
erik [133]

Answer:

The number that was added to the previous number is doubled.

For example:

2+1 = 3

2x1= 2

3+2= 5

2x2=4

5+4=9

4x2=8

8+9=17

I hope this helps:)
