Find the number if 6% of it is 20% of 6<br> thanks plz help!!!

Y_Kistochka [10]

Answer:

20.

Step-by-step explanation:

We can begin by calculating 20% of 6:

0.2 × 6= 1.2

If 1.2 is 6% of the number, we can set up an equation like this:

0.06x = 1.2

Now, divide on both sides, giving us:

x= 20.

3) An oil prospector will drill a succession of holes in a given area to find a productive well. The probability that he is succ

KATRIN_1 [288]

Answer: 0.128

Step-by-step explanation:

The geometric probability of getting success on nth trial is given by :-

$P(n)=p(1-p)^{n-1}$

Given : The probability that he is successful on a given trial $p= 0.2$ .

Then , the probability that the third hole drilled is the first to yield a productive well is given by :-

$P(3)=0.2(1-0.2)^{3-1}=0.128$

Hence, the probability that the third hole drilled is the first to yield a productive well = 0.128
