A box contains red markers, blue markers, and green markers. There are more blue markers then red markers. The probability of ra
tester [92]
One possible probability is 1/10.

Since P(b) = 1/5, we know that there must be some multiple of 5 as the total number of markers.

There cannot be 5 markers in the box; if there is only 1 blue out of 5 markers, it is impossible for there to be any red markers and have a probability less than 1/5.

Using a total of 10 markers, there would be 2/10 blue to have a probability of 1/5.  This means there would be 1/10 red.  We know nothing about the number of green markers, so there can be as many as we want, in theory.  This means the other 7 markers could be green.

25 points<br> If ƒ(x) = 1/x, which equation represents the f transformed as follows: 2ƒ(x + 3) ?
-Dominant- [34]

Answer:

B   y  = 2/(x+3)

Step-by-step explanation:

f(x) = 1/x

Replace x with x+3

g(x) = 1 /(x+3)

Then multiply it by 2

h(x) = 2 *(1/ (x+3))

h(x) = 2/(x+3)

in order to become a member at the gym there is a $75 startup fee. Saint have to pay $15 per month. write an equation in slope i
Ludmilka [50]

Answer:

I think the answer to your question is y=15x+75

Step-by-step explanation:

To become a member you automatically have to pay $75. $75 is your y-intercept because before you work at the gym you have to pay $75. The $15 would be your x or your slope because each month you would have to pay 15 dollars. So the slope intercept form would be y=15x+75. I hope that helps.
