Two number cubes are rolled.
aliina [53]

Answer:

1/18

Step-by-step explanation:

Assuming the die are regular 1,2,3,4,5,6

P(2) = number of 2's/ total numbers on die

      = 1/6

Roll again

Assuming the die are regular 1,2,3,4,5,6

P (numbers greater than 4) = {5,6}/total numbers on die

                                               =2/6 = 1/3

P (2, then  number greater than 4) = 1/6 * 1/3 = 1/18

Shayna's school is selling tickets to a play. On the first day of ticket sales the school sold 13 senior citizen tickets and 13
jasenka [17]

The price of one senior citizen ticket is 8$ and one student ticket is 12$.

<h3>What is the equation?</h3>

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Let the price of one senior citizen ticket = x

And the price of one student ticket = y

Given that, on the first day of ticket sales, the school sold 13 senior citizen tickets and 13 student tickets for a total of $260

The school took in $212 on the second day by selling 13 senior citizen tickets and 9 student tickets.

13x +13y = 260

13x + 9y = 212

Subtract the equation  from first

13x +13y - (13x + 9y) = 260 - 212

4y = 48

y = 48/4

y = 12

Substitute the value of y in the equation 13x + 9y = 212

13x + 9(12) = 212

13x + 108 = 212

13x = 212 - 108

13x = 104

x = 104/13

x = 8

Hence, the price of one senior citizen ticket is 8$ and one student ticket is 12$.

Given the sequence tn defined recursively below, find t4.
Alina [70]

Answer:

t_4 = 20

Step-by-step explanation:

The base case in the recursive function are:

t_1 = 1

t_2 = 2

The recursive case is equal to:

t_n = 2t_{n-1} + 3t_{n-2}

So replace t_n for t_4:

t_4 = 2t_{3} + 3t_{2}

In the new expression t_2 is a base case so you don't have to worry for that part, but t_3 is still the recursive case so evaluate again in t_n

t_3 = 2t_{2} + 3t_{1}

t_2 and t_1\\ are define as base cases so you replace for it's numbers:

t_3 = 2(2) + 3(1) = 7

Now return to t_4 and replace for the new values:

t_4 = 2(7) + 3(2) = 14 + 6 = 20

So the final answer is 20
