4 Tim carried out an experiment where he tossed 20 coins together and observed
the number of heads showing. He repeated this experiment 10 times and got
the following results:
11, 9, 10, 8, 13, 9, 6, 7, 10, 11
a) Use Tim’s data to get the probability of obtaining a head.
b) He tossed the 20 coins for the 11th time. How many heads should he expect
to get?
c) He tossed the coins 1000 times. How many heads should he expect to see?

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

do you have an easier question cause this shh is hard like theheck

step-by-step explanation:

yeah i know the problem you need. i am taking it right now. the answer is step 3
