I did this my sophmore year in highschool and I'm trying to remember lol. But first you add all the marbles together. 1+4+3. its eight. and since the marble was put back in this makes it an independant event. i believe the answer would be 2/8 considering that there isnt enough numbers to follow through with the equation of (P(a or b)=P(a)xP(b) . P is the probability and a and b are the variabls that represent the events. You would plug in the numbers of the probabilities into the equation, if you think the question calls for it. sorry it may not have been a staright up answer.

In each table, determine if y is proportional to x. Explain why or why not.
Marina86 [1]

Answer: yes

Step-by-step explanation:

You’re multiplying every x value by 4 to get the y values

(Someone got mad at me for not including a better explanation so here you go:

x = 3    y = 12..... 3(k) = 12 (divide both sides by three)

k = 4

x = 5   y = 29..... 5(k) = 20 (divide both sides by five)

k = 4

So on and so forth for the rest of the table

Write the first four terms in the following sequences. A(n+1)=A(n)−5 for n≥1 and A(1)=9 .
luda_lava [24]

Answer:

Step-by-step explanation:

A(1) = 9

A(n+1) = A(n) - 5

n = 1 ;     A(1+1) = A(1) - 5

             A(2) =  9 - 5

             A(2) = 4

n = 2 ;     A(2+1) = A(2) - 5

             A(3) =  4 - 5

             A(3) = 1

n = 3 ;     A(3+1) = A(3) - 5

             A(4) =  1 - 5

             A(4) = -4

n = 4 ;     A(4+1) = A(4) - 5

             A(5) =  -4 - 5

             A(5) = -9

First four terms are: 9 , 4 , 1 , -4 , - 9
