Second statement is more postulate you can't prove it, so the statement is clearly a thrm.

Answer:

16/29

Step-by-step explanation:

P(A∪B) = P(A) + P(B) - P(A∩B)

P(basketball or baseball) = P(basketball) + P(baseball) - P(both)

= (13/29) + (7/29) - (4/29)

= 16/29

The probability that a randomly chosen student plays either sport is 16/29.

Find two numbers with a sum of 20 and a difference of 14

sergey [27]

Find two numbers with a sum of 20 and a difference of 14

Make two equations

X+Y=20

X-Y=14

Now add x since y cancels out and add 20+14 To end up with

2x=34

Now divide 2 both sides to get x alone

2x/2=34/2

X=17

Now substitute x answer to first equation and solve for y

17+y=20

Subtract 17 both sides

Y= 3

Your two numbers are

3 and 17

Hay there can anybody answer this

Alexus [3.1K]

Answer:

x = 12

Step-by-step explanation:

The two marked angles where the transversal crosses the parallel lines are alternate interior angles, so are congruent. This fact gives you the relation you need to solve for x.

4x +12 = 60

4x = 48 . . . . . . subtract 12

x = 12 . . . . . divide by 4
