Marissa is drawing coins from a bag that contains 5 pennies, 4 nickels, 5 m
and 2 quarters
a. what is the probability that she will draw a nickel? write your answers
fraction, as a decimal, and as a percent.
if one penny. two dimes, and one quarter are added to the bag. what is the
new probability that marissa will draw a nickel? write your answer as a
fraction, as a decimal, and as a percent.
c.
in which situation is it more likely that marissa will draw a nickel?

Step-by-step explanation:

Total no of coins in the bag

a) the probability that she will draw a nickel=no of nickels/total coins

=

If one penny, two dimes and one quarter added then we have total coins new as =

the

new probability that Marissa will draw a nickel= new nickel coins/new total

=

IN the first situation there is more likely as probability is more.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
