Justin writes the letters i-l-l-i-n-o-i-s on cards and then places the card in a hat. what are the odds in favor of picking an i? a. 5: 3 b. 3: 5 c. 3: 7 d. 1: 2

B. 3 : 5

Step-by-step explanation:

We are given that,

Justin writes the letters I-L-L-I-N-O-I-S on the cards.

Now, he placed the cards inside a hat.

It is required to find the odds of picking an I.

Since, 'Odds in favor of picking an I is the ratio of picking an I and not picking an I'

Now, the possibility of picking an I =

And, the possibility of not picking an I =

Thus, the odds in favor of picking an I is :

That is, the odds in favor of picking an I is 3 : 5.

Hence, option B is correct.

they disappear if your absent from to long. i found out that the hard way.

step-by-step explanation:

brainliest lol i just need one more brainliest.

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 ☺
