Let tk be the number of ways to choose k beads from a drawer that contains 10 red beads, 8 blue beads, and 11 green beads. Find the generating function for the sequence {tk} 29 k = 0. Do not find a formula for tk.
Answer:
[tex]\mathbf{G(x) = (1 + x)^{29}}[/tex]
Step-by-step explanation:
From the given information;
The total number of beads = 10 + 8 + 11 = 29
To choose k beads out 29 beads, let assume that [tex]t_k[/tex] be the no. such that:
[tex]t_k = ( ^{29}_{k}) \ \ \ where; k =0,1,2,3,....,29[/tex]
∴
The sequence [tex]\{ t_k\}^{29}_{k=0} = (^{29}_{k})[/tex]
The generating function for [tex]\{ a_k \}^n_{k=0}[/tex] is:
[tex]G(x) = a_o +a_1x +a_2x^2 +...+a_nx^n[/tex]
[tex]G(x) = \sum \limits ^{n}_{k=0} \ a_k x^k[/tex]
For the sequence above;
[tex]G(x) = \sum \limits ^{29}_{k =0 } (^{29}_{k}) x^k[/tex]
By applying binomial series [tex](1+x)^n = \sum \limits ^n_{k=0} ( ^n_k) x^k[/tex]
Thus:
[tex]\mathbf{G(x) = (1 + x)^{29}}[/tex]

The carter family budgets a total of 2,700 for a ski vacation in Colorado if they plan to go spend 275$ per day and 1,000 on meals about how many days n can the carter family go on vacation ?
Answer:
275n + 1000 = 2700
They will go 6 days on vacation.
Step-by-step explanation:
Given that the Carter family wants to go on vacation with a budget of $ 2700, of which $ 1000 will be used exclusively for food, and for each day of stay $ 275 will be spent, the formula to obtain the number of days they can spend on vacation is following:
1000 + 275n = 2700
275n = 2700 - 1000
n = 1700/275
n = 6.18
Therefore, with this amount, the Carters will be able to spend 6 days on vacation, and they will have money left over.

Elvira sells a total of 364 bags to earn a profit of $200 and this can be determined by using the unitary methods.
Given :
Elvira makes money to buy decorations for the cafeteria by selling little bags of chips in the snack bar. If each bag costs $0.35 and she can sell the bag for $0.90.Total profit earn = $200The following steps can be used to determine the total number of bags she sells to earn the profit of $200:
Step 1 - First find the total profit she earns to sell one bag.

The radius of the sphere is 9 inches. Which equation can be used to find the surface area of the sphere?
Answer:
Option (2)
Step-by-step explanation:
Formula to get the surface area of a sphere is,
Surface area = 4πr²
Here 'r' = Radius of the sphere
We have to calculate the surface area of a sphere with radius r = 9 inches.
By substituting the value of r in the formula,
S = 4π(9)²
Therefore, Option (2) will be the correct option.
Answer:
B. S = 4 pi r squared = 4 pi (9) squared

A
the fee for the use of the school gym
B
the number of people in the yoga class
C
the cost of the yoga class for each person attending the class
D

Solve the system using substitution.
3x - 4y = 11
y + 3x = 1
Answer:
x= 1
y= -2
Step-by-step explanation:
1. y+3x=1 subtract 3x from both side to get y= 1-3x
2. Put the new found y value in the equation
3x-4(1-3x)=11
3. Distribute the 4
3x-4+12x=11
4. Add 4 to both sides
3x+12x=15
5. Add the x's
15x=15
6. Solve for x
x=1
7. Plug in the x in the y equation y= 1-3x
y=1-3(1)
8. Solve for y
y= -2
The solution to the system of equations is x = 1 and y = -2.
To solve the system of equations using substitution, we need to solve one of the equations for one variable in terms of the other variable and then substitute that expression into the other equation. Let's solve the second equation for y and then substitute it into the first equation:
Given system of equations:
3x - 4y = 11
y + 3x = 1
Step 1: Solve the second equation for y:
y = 1 - 3x
Step 2: Substitute the value of y from equation (2) into equation (1):
3x - 4(1 - 3x) = 11
Now, let's solve for x:
3x - 4 + 12x = 11
Combine like terms:
15x - 4 = 11
Step 3: Solve for x:
15x = 11 + 4
15x = 15
x = 15 / 15
x = 1
Step 4: Now that we have the value of x, we can find y using equation (2):
y = 1 - 3(1)
y = 1 - 3
y = -2
So, the solution to the system of equations is x = 1 and y = -2.
