If they have $284.25 to spend on parking and admission. Parking is $9.25, and tickets cost $27.50 per person, including tax. The number of people that can go to the amusement park is: 10 people.
How to find the number of people?Let a represent the number of people who can go to the amusement park
Formula an equation
9.25 + 27.50a = 284.25
Combine like terms
27.50a = 284.25 - 9.25
27.50a = 275
Divide both side by 27.50a

Using the exterior angle theorem, angle z is measured as 134°.which is the correct answer that would be an option (D).
What is the Exterior Angle Theorem?The exterior angle theorem is a triangle theorem that asserts that the measure of the external angle created by an extended side of a triangle is equal to the sum of the measures of the triangle's remote interior angles.
The given data will be the following as:
Exterior angle to angle C of triangle ABC = z
The remote interior angle of triangle ABC are angled A = 58° and angle B = 44°.
Therefore:
The measure of angle z = measure of angle A + measure of angle B [according to the exterior angle theorem]
Substitute the values and we get
Measure of ∠z = 77 + 57
Measure of ∠z = 134°

graph the linear inequality y≤-2/5x-4
The graph of the inequality, y ≤ -2/5x - 4, is shown below
Graph of Linear inequalitiesFrom the question, we are to graph the given linear inequalities.
The given linear inequalities is y ≤ -2/5x - 4.
To graph the linear inequality,
First, we will draw the line of the equation y = -2/5x - 4
To draw the line, we will use the x-intercept and y-intercept.
y-intercept
When x = 0
y = -2/5x - 4
y = -2/5(0) - 4
y = 0 - 4
y = -4
Thus, the coordinate of the y-intercept is (0, -4)
x-intercept
When y = 0
y = -2/5x - 4
0 = -2/5x - 4
4 = -2/5x
4 × 5 = -2x
20 = -2x
x = 20/-2
x = -10
Thus, the coordinate of the x-intercept is (-10, 0)
Now, using the coordinates of the x and y-intercepts, the line of the graph is shown.
Since the sign of the inequality is less than or equal to (≤), the line is a solid line and the solution is below the line.

cost. [1.4 and 1.5]
The final cost of the sliced turkey and provolone cheese is $31.84
How to calculate the final cost of both products?The first step is to calculate the cost of the sliced turkey
The pounds of turkey is 24.8
The amount of the turkey is $1.89
The cost is = 24.8/1.89

The next step is to calculate the cost of the provolone cheese
The pounds of the provolone cheese 38.2
The amount of provolone cheese is $2.05
The cost is = 38.2/2.05
= 18.63
Therefore the final cost can be calculated as follows

One factor of f (x ) = 4 x cubed minus 4 x squared minus 16 x + 16 is (x – 2). What are all the roots of the function? Use the Remainder Theorem.
A factor of f(x) is (x – 1).
A factor of f(x) is (x + 1).
Both (x – 1) and (x + 1) are factors of f(x).
Neither (x – 1) nor (x + 1) is a factor of f(x).
The answer is option A) A factor of f(x) is (x – 1).
What is the remaining theorem?
Remainder Theorem is a method for dividing polynomials according to Euclidean geometry. This theorem states that when a polynomial P(x) is divided by a factor (x - a), which isn't really an element of the polynomial, a smaller polynomial is produced along with a remainder.
f(x) = 4x3 - 4x2 - 16x + 16 [Given]
One aspect is (x - 2)
The remaining theorem is used to:
Where q(x) is the quotient polynomial and r(x) is the remainder polynomial, f(x) = (x-2)q(x) + r(x).
As (x-2) is a factor of f, r(x) equals 0. (x)
f(x) = (x-2)·q(x) (x)
q(x) = f(x)/ (x-2) (x-2)
[4x3 - 4x2 - 16x + 16]/ (x - 2) (x - 2)
= [4x2 (x - 1) - 16 (x - 1)]
/ (x - 2) (x - 2)
By even more simplifying
= [(x - 1) (4x2 - 16)]
/ (x - 2) (x - 2)
excluding 4 as common
= [(x - 1) 4 (x2 - 4)]
/ (x - 2) (x - 2)
With the use of the algebraic formula a2 - b2 = (a + b) (a - b)
= [(x - 1) 4 (x + 2) (x - 2)]
/ (x - 2) (x - 2)
= [4 (x - 1) (x - 2) (x + 2)]
/ (x - 2) (x - 2)
The roots are therefore 2, -2, and 1.
there the ans is A) A factor of f(x) is (x – 1).

A pharmaceutical company receives large shipments of aspirin tablets. The acceptance sampling plan is to randomly select and test 59 tablets, then accept the whole batch if there is
only one or none that doesn't meet the required specifications. If one shipment of 3000 aspirin tablets actually has a 2% rate of defects, what is the probability that this whole
shipment will be accepted? Will almost all such shipments be accepted, or will many be rejected?
The probability that this whole shipment will be accepted is
(Round to four decimal places as needed.)
4
Answer:
The probability that this whole shipment will be accepted is 72.39%.Step-by-step explanation:
The probability of no defects with 2% rate of defects:
P(no defects) = 59*0.02⁰*(1 - 0.02)⁵⁹ = 0.3583 (rounded) = 35.83%Probability of exactly one defect:
P(1 defect) = 59*0.02¹*(1 - 0.02)⁵⁸ = 0.3656 (rounded) = 36.56%Probability of one or no defects:
P(1 or none) = 35.83% + 36.56% = 72.39%This indicates that:
100% - 72.39% = 27.61% of shipments will be rejected, it is a lot, so many shipments will be rejectedThe probability that this whole shipment will be accepted is 72.39%.

Se divide una suma de Gs. 1.365.000 en tres capitales. Colocados respectivamente al 2%, 3% y 4%, producen el mismo interés simple anual. Calcula dichos capitales
Los capitales depositados en las cuentas de 2 %, 3 % y 4 % son 630.000, 420.000 y 315.000, respectivamente.
¿Cuántos capitales se deben ingresar en tres cuentas para obtener ganancias por interés simple?
En este problema tenemos el caso de una suma de dinero distribuida y depositada en tres cuentas con tres tasas de interes simple distintas. Existe una tasa de interés simple cuando el interés generado sobre el capital no es acumulativo en el tiempo. El modelo de interés simple es descrito por la siguiente fórmula:
C' = C · (1 + r / 100)
Donde:
C - Capital inicial.C' - Capital final.r - Tasa de interés, en porcentaje.A continuación, describimos la ganancia registrada en cada cuenta tal que produce la misma ganancia:
Cuenta al 2 %:
z = x · (2 / 100)
z = 0.02 · x
0.02 · x - z = 0
Cuenta al 3 %:
z = y · (3 / 100)
z = 0.03 · y
0.03 · y - z = 0
Cuenta al 4 %:
z = (1.365.000 - x - y) · (4 / 100)
z = 54600 - 0.04 · x - 0.04 · y
0.04 · x + 0.04 · y + z = 54600
La solución de este sistema de ecuaciones lineales se obtiene mediante métodos numéricos:
(x, y, z) = (630.000, 420.000, 12.600)
Finalmente, el capital depositado en la cuenta al 4 % es:
c = 1.365.000 - 630.000 - 420.000
c = 315.000
Se deposita capitales de 630.000, 420.000 y 315.000 en las cuentas de 2 %, 3 % y 4 %, respectivamente.
