Tiya flipped a coin 40 times. The coin landed heads up 16 times and tails up 24 times. Part A: Based on the results, what is the experimental probability of the coin landing heads up? Show your work. (5 points) Part B: What is the theoretical probability of the coin landing heads up? Show your work. (5 points)

Part A: 2/5 or 0.4 or 40%

Part B: 1/2 or 0.5 or 50%

Step-by-step explanation:

Part A:

Experimental probability is # of times event occurs / total # of trials

16/40

Simplifies to 2/5 or 0.4 or 40%

Part B:

Theoretical probability is the # of favorable outcomes / out of total possible outcomes.

Since a coin is 2 sided and we favor heads up in this case.

The theoretical probability is 1/2 or 0.5 or 50%

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,

mrb

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
