A bag contains 12 pennies, 9 nickels, 11 dimes and 3 quarters. A coin is selected at random from the bag. Find the probability.

6 0

Probablity=desiredoutcomes/totalpossibleoutcomes

see which ones fit
dimes and quarters are over 9 cents
there are 11+3 or 14 of them

total outcomes=12+9+11+3=35

probablity=14/35=2/5

probablity is 2/5

Consider the function $f(x)=\sqrt{x}.$ This function has:

the domain $x\in [0,\infty);$
the range $y\in [0,\infty).$

If the domain of unknown function is $[a,\infty),$ then $x\ge a$ or $x-a\ge 0.$ This means that you have $\sqrt{x-a}$ as a part of needed function.

If the range of unknown function is $[b,\infty),$ then $y\ge b.$ This means that you have to translate function b units up and then the expression of the function is
