Based on the dotplot of the simulation results and the pool player's last 20 games, which conclusion can be
drawn?
A professional pool player claims that she sinks at least
one ball in a pocket on 80% of her opening break
shots. In a recent set of 20 games, she sunk at least
one ball on her break shot in only 14 of the games. A
simulation of 100 trials was conducted to see how
unusual these most recent games are.
The Professional Pool Player
25
O The player's true probability of sinking at least one
ball on her break is 27%.
O Another 100 simulated trials would show a much
different outcome; therefore, we cannot draw any
conclusions.
It is most likely that she would sink at least one ball
during her break exactly 16 times,
There is about a 27% chance of her sinking at least
one ball on her break 14 or fewer times in 20 games.
This result is not unusual and there is no convincing
evidence that her average is less than 80%.

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺

step-by-step explanation:

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
