Let x be the number of tickets sold
Cost of x tickets = 32.5.x
Cost of convenience = 3.3.x
Process charges (for ONE ORDER, whatever the number of tickets) = $5.90

Hence:
$32.5(x) + $3.3(x) + $5.90 = $220.70

$35.8(x) = $220.90-$5.90

$35.8(x) = $214.8

And x = 214.8/35.8 = 6 tickets

Answer: $\bold{a_2=-8\qquad \qquad a_r=5r-18}$

<u>Step-by-step explanation:</u>

Given: a₆ = 12 a₈ = 22

$d=\dfrac{a_8-a_6}{8-6}\quad = \dfrac{22-12}{8-6}\quad =\dfrac{10}{5}\quad =\boxed{5}$

$a_n=a_0+d(n-1)\\\\\\\underline{\text{Use}\ a_6\ \text{to find}\ a_o}\\a_6=a_o+5(6-1)\\\\12=a_o+5(6-1)\\\\12=a_o+25\\\\a_0=\boxed{-13}\\\\\\\underline{\text{Equation:}}\\a_n=13+5(n-1)\\.\quad =-13+5n-5\\.\quad =5n-18\\\\\\\underline{2^{nd\ term:}}\\a_2=5(2)-18\\.\quad = 10-18\\.\quad =\boxed{-8}\\\\\\\underline{r^{th}\ term:}\\\boxed{a_r=5r-18}$

Answer:

C. Events E and A are independent

Step-by-step explanation:

we will verify each options

(a)

We can use independent events formula

P(B∩C)=P(B)*P(C)

we are given

P(B)=0.4

P(C)=0.25

P(B∩C)=0.05

now, we can plug these values into formula

and we get

0.05=0.4*0.25

0.05=0.1

we can see that left side is not equal to right side

so, this is FALSE

(b)

We can use independent events formula

P(D∩A)=P(D)*P(A)

we are given

P(D)=0.25

P(A)=0.6

P(D∩A)=0.1

now, we can plug these values into formula

and we get

0.1=0.25*0.6

0.1=0.15

we can see that left side is not equal to right side

so, this is FALSE

(c)

We can use independent events formula

P(E∩A)=P(E)*P(A)

we are given

P(E)=0.5

P(A)=0.6

P(E∩A)=0.3

now, we can plug these values into formula

and we get

0.3=0.5*0.6

0.3=0.3

we can see that both sides are equal

so, this is TRUE

(d)

We can use independent events formula

P(D∩B)=P(D)*P(B)

we are given

P(D)=0.25

P(B)=0.4

P(D∩A)=0.15

now, we can plug these values into formula

and we get

0.15=0.25*0.4

0.15=0.1

we can see that left side is not equal to right side

so, this is FALSE
