Okay so first since there are 4 red marbles, 4 blue marbles, and 12 yellow marbles, you add them together so the whole total would be 20 marbles now. Since there are 4 marbles, the probability of her pulling it out would be 4/20. So now that she took 1 red marble away, we have 19 marbles left. So now that has been finished, she 1 more yellow marble away so now we have 12/19. Now that it's completed you multiply the two, and now you should have 12/95, divide 12/95 and you'll get 0.126315789 in other words rounded that too the nearest hundredth and you'll get 0.13
Each term in the sum differs by 6, so that the
th term is determined by
. The last term is 70, so there are

terms in the sum. If

then it's also true that

and joining the sums gives us



Answer:
I thing option A. all real numbers.
but IAM not exactly sure....
Answer:
$104,167 approx.
Step-by-step explanation:
Step one:
Given data
Morgan made $12,500 on the sale of a home.
Her commission she earns in selling homes is 12%
Step two:
let the cost of the home be x
So 12% of x= 12,500
12/100*x= 12,500
0.12*x=12,500
0.12x=12,500
divide both sides by 0.12
x= 12,500/0.12
x=$104,166.66
x=$104,167
ANSWER
Find out the how long will the Yellow balloon be higher than the orange balloon.
To proof
Now the diagram is given below
As given
A yellow hot-air balloon is 100 feet off the ground and rising at rate of 8 feet per second.
i.e height of the yellow baloon off the ground = 100 feet
rising at rate = 8 feet per second.
.An orange hot-air balloon is 160 feet off the ground and rising at a rate of 5 feet per second.
i.e height of the orange baloon off the ground = 160 feet
rising at rate = 5feet per second.
Formula

Relative velocity = rising rate of yellow balloon - rising rate of orange balloon
= 8 -5
= 3 feet per second
Relative distance = height of the yellow baloon off the ground - height of the orange baloon off the ground
= 160 -100
= 60 feet
put in the formula

= 20 second
after 20 second Yellow balloon will be higher than the orange balloon.
Hence proved
