Well, the common denominator of6 and 15 would be three so you would get 2 and 3

the common denominator of 30 and 80 would be 10 and it would equal 3 and 8

A coin is flipped until 3 heads in succession occur. list only those elements of the sample space that require 6 or less tosses.
Mashutka [201]

we are given

A coin is flipped until 3 heads in succession occur

so, firstly, we will find sample space

S={HHH , THHH , HTHHH, TTHHH , TTTHHH , HTTHHH , THTHHH , HHTHHHH, ......}

now, we are given that

list only those elements of the sample space that require 6 or less tosses

so, we can see that sample space

S={HHH , THHH , HTHHH, TTHHH , TTTHHH , HTTHHH , THTHHH , HHTHHHH, ......}

There are infinite such possibilities

so, there are infinite number of elements in space

and we know that

discrete sample space will always have finite elements

but we have infinite number of sample space elements here

so, this is not discrete sample space...........Answer

Eliminate x's
multiply 2nd equation by -2 ad add to first

2x+3y=9
<u>-2x-10y=-16 +</u>
0x-7y=-7

-7y=-7
divide by -7
y=1

sub back

2x+3y=9
2x+3(1)=9
2x+3=9
minus 3
2x=6
divide 2
x=3


x=3
y=1

I need help with this equation please!<br><br> 15- w/4 = 28
Luda [366]

Answer:

w= -52

Step-by-step explanation:

We simplify the equation to the form, which is simple to understand  

15-w/4=28

Simplifying:

15-0.25w=28

We move all terms containing w to the left and all other terms to the right.  

-0.25w=+28-15

We simplify left and right side of the equation.  

-0.25w=+13

We divide both sides of the equation by -0.25 to get w.  

w= -52

Hope it Helps :) !!
