Answer:

35/132.

Step-by-step explanation:

There are a total of 12 balls. So:

Prob(First is green) = 5/12.

After the first selection there are 11 balls left.

Prob(The second is red) = 7/11.

The required probability = 5/12 * 7/11

= 35/132.

Note: the probabilities are multiplied because the 2 events are independent.

How should I solve this? I tried to but I couldn't get past the quadratic formula.
xxMikexx [17]
First multiply all terms by z
8-z^2=4z

Then order into standard form
-z^2-4z+8=0

Multiply the equation by -1
z^2+4z-8=0

Plug into quadratic equation
-4±√16-4(-8)
-4±√48

(-4±4√3)/2
-2±2√3

Final answer: z=-2± 2√3

For each sequence,find the first 4 terms and the 10th term<br> a) n+5<br> b)2n-1
dsp73

Answer:

a)6,7,8,9 and 10th term is 15.

b)1,3,5,7 and 10th term is 19.

Step-by-step explanation:

Given a) n+5

b)2n-1

Solution for  a) n+5

Taking the value of n is 1 we get the first term of the sequence;

n+5=1+5=6

Similarly taking the value of n 2,3,4 we get;

2+5=7\\3+5=8\\4+5=9

And for 10th term we take the value of n is 10 and get;

n+5=10+5=15

So the solution for 1st sequence is 6,7,8,9 and 10th term is 15.

Solution for  b)2n-1

Taking the value of n is 1 we get the first term of the sequence;

2n-1=2\times1-1=2-1=1

Similarly taking the value of n 2,3,4 we get;

2n-1=2\times2-1=4-1=3\\2\times3-1=6-1=5\\2\times4-1=8-1=7

And for 10th term we take the value of n is 10 and get;

2n-1=2\times10-1=20-1=19

So the solution for 2nd sequence is 1,3,5,7 and 10th term is 19.
