What is the geometric mean between 7 and 12

9.16515138991168 or 9.2/9.17

depends on the nearest decimal place the question asked you to answer in.

Step-by-step explanation:

to find the geometric mean of any two numbers,

you need to add both numbers

so 7*12 which is 84

then you would have to square the result

√84 = 9.16515138991168

or if rounded to one decimal place it would be 9.2.

Hope this helps:)

let,

a = 7

b = 12

then,

geometric mean = _/ab

= _/ 7×12

= _/ 84

=_/(9.16)^2

=9.16

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
