A fruit company recently released a new applesauce. By the end of its first year, profits on this product amounted to $ 35 comma 900.$35,900. The anticipated profit for the end of the fourth year is $ 44 comma 300.$44,300. After the first year, the ratio of change in time to change in profit is constant. Let x be years and P be profit in dollars. A. Write a linear function P(x) that expresses profit as a function of time.
Answer:
P(x) = 35,900 + 2,800(x-1)
Step-by-step explanation:
P(x)
P(1) = $35,900
P(4) = $44,300
Difference in profits
P(4) - P(1)
= P(3)
= $44,300 - $35,900
= $8,400
Rate of change per year = $8,400 / 3
= $2,800 per year
The linear equation
P(x) = 35,900 + 2,800(x-1)
Where
x = number of years
2.49 Encuentre los errores en cad uno de las siguientes aseveraciones: a) las probabilidades de que un vendedor de automóviles venda 0,1,2 o 3 unidades en un dia dado de febrero son 0.19, 0.38, 0.29 y 0.15. Respectivamente b) la probabilidad de que llueva mañana es de 0.40 y la probabilidad de que no llueva es 0.52 c) las probabilidades de que una impresora cometa 0,1,2,3 o 4 o más errores al imprimir un documento son 0.19, 0.34, -0.25, 0.43 y 0.29 respectivamente. d) al sacar una carta de una baraja en un solo intento la probabilidad de seleccionar un corazón es ¼, la probabilidad deseleccionar una carta negra es ½, y la probabilidad de seleccionar una carta de corazones y negra es de 1/8
Answer:
Step-by-step explanation:
a) Si se suman las probabilidades de venta, es decir:
Probabildad de vender 0 auto ( es decir que no vendió) = 0,19
Probabildad de vender 1 auto = 0,38
Probabildad de vender 2 autos = 0,29
Probabildad de vender 3 autos =0,15
Da por resultado: 1,01
1,01 > 1
Ninguna probabilidad puede ser mayor que
b) LLover y no llover son condiciones excluyentes en relación al evento, es decir en relación a lluvia cualquier día o llueve o no llueve de tal forma
que las dos situaciones conforman el universo completo y deben sumar 1. en este caso el error s que suman 0.92 cando deberían sumar 1
c) No existen probabilidades negativas ( en este caso señalan -0,25 como una probabilidad
d) La probabilidad de sacar una carta de corazones es 1/4 (correcta pues hay la misma cantidad de carta de las cuatro viras tipo ( diamante, trebo, corazones y el otro).
La mitad de las cartas son negras, de tal modo que 1/2 es correcto valor para esta probabilidad.
La probabilidad de que sea corazones y negra s 1/4*1/2 = 1/8
Luego no hay error en esta aseveración
solve for s if -2=4r+2
Answer:
[tex]\boxed {s = -2 - 4r}[/tex]
Step-by-step explanation:
Solve for [tex]s[/tex]:
[tex]-2 = 4r + s[/tex]
-Switch sides:
[tex]-2 = 4r + s[/tex]
[tex]4r + s = -2[/tex]
-Subtract [tex]4r[/tex] to both sides:
[tex]4r - 4r + s = -2 - 4r[/tex]
[tex]\boxed {s = -2 - 4r}[/tex]
What is an equation in point-slope form of the line that
passes through (-3, -1) and has a slope of 2
Step-by-step explanation:
To find an equation of a line in point slope form when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1) [/tex]
where
m is the slope
( x1 , y1) is the point
From the question the point is (-3, -1) and slope 2
The equation is

Find f(3).
f(x) = x2 + 5x - 9
A) 7
B) 10
C) 9
D) 15
Answer:
f(3) = 15. Correct: D)
Explanation:
Numeric Value of a Function
The value of a function f(x) when x = a is calculated by replacing the x for a. We have the function:
[tex]f(x)=x^2+5x-9[/tex]
It is required to find f(3), or the numeric value of f when x=3. Replace x for 3
[tex]f(3)=3^2+5(3)-9[/tex]
[tex]f(3)=9+15-9[/tex]
[tex]f(3)=15[/tex]
A) Incorrect. f(3) is not 7
B) Incorrect. f(3) is not 10
C) Incorrect. f(3) is not 9
D) Correct. f(3) =15 as found above.

Item 21 A teacher is making identical activity packets using 92 crayons and 23 sheets of paper. What is the greatest number of packets the teacher can make with no items left over? Item 21 A teacher is making identical activity packets using 92 crayons and 23 sheets of paper. What is the greatest number of packets the teacher can make with no items left over?
Answer:
The greatest number of packets the teacher can make with no items left over is 23.
Step-by-step explanation:
Total number of crayons = 92
Total number of sheets of paper = 23
To find the greatest number of packets the teacher can make with no items left over, find Highest Common Factor (H.C.F) of 92 and 23
92 = [tex]2^2[/tex] × 23
23 = 23
So,
H.C.F(92,23) = 23
Therefore, the greatest number of packets the teacher can make with no items left over is 23.

What is the equation of the line in point slope form given a slope of -3 and a point of (-2,-5)?
Answer:
y = -3x - 11
Step-by-step explanation:
Use the given slope and point in the point-slope equation. Solving this will give us the y-intercept equation.
Point-slope formula: y - y = m(x - x)
Plug in the slope and point
y - (-5) = -3(x - (-2))
Subtracting negatives will make them positive. Multiply out the -3 to what is in the parentheses.
y + 5 = -3x - 6
Subtract the 5 from both sides
y = -3x - 11
The equation of the line is y = -3x - 11
In the general population, one woman in eight will develop breast
cancer. Research has shown that 1 woman in 600 carries a mutation of
the BRCA gene. Eight out of 10 women with this mutation develop
breast cancer.
a) Find the probability that a randomly selected woman will develop
breast cancer given that she has a mutation of the BRCA gene. b) Find the probability that a randomly selected woman will carry the mutation of the BRCA gene and will develop and will develop breast cancer? c) are the events of carrying this mutation and developing Brest cancer independent or dependent?
Answer:
a) 8/10
b) [tex]0.001 \overline{33}[/tex]
c) Independent events
Step-by-step explanation:
The given information are;
The proportion of women than carries a mutation of the BRCA gene, P(A) = 1/600
The proportion of women in which the mutation develops breast cancer, P(B) = 8/10
a) The probability that a randomly selected woman will develop breast cancer given that she has a mutation of the BRCA gene is given as follows;
1 × P(B) = 1 × 8/10 = 8/10
b) The probability, P that a randomly selected woman woman will carry the mutation of the BRCA gene and will develop breast cancer is given as follows;
P(A) × P(B) = 1/600×8/10 = 1/750 = [tex]0.001 \overline{33}[/tex]
c) The events are dependent
Given that P(A) × P(B) = P(A∩B), the events of carrying the mutation and developing Breast cancer are independent events.

Brody invested $220 in an account paying an interest rate of 3.6% compounded
annually. Assuming no deposits or withdrawals are made, how much money, to the
nearest ten dollars, would be in the account after 17 years?
Answer:
400
Step-by-step explanation:
Delta
The amount after 17 years is $400
How to determine the amount after 17 years?The given parameters are:
Principal, P = $220Rate, r = 3.6%Time, t = 17 yearsThe interest rate is compounded annually;
So, the amount after t years is:
A = P *(1 + r)^t
This gives
A = 220 * (1 + 3.6%)^17
Evaluate
A = 401.36
To the nearest ten dollars, we have:
A = 400
Hence, the amount after 17 years is $400

Answer:
Infinite amount of solutions
Step-by-step explanation:
Step 1: Write equation

Step 2: Solve for x
Distribute 5x + 10 = 5x + 10Subtract 10 on both sides: 5x = 5xDivide both sides by 5: x = xWe see here that x is infinite amount of solutions. We can plug in any value x and it would render the equation true.
