Where a is the initial value and b is the rate of increase per period.
Let I(t) represent Jennifer’s investment account balance after t years, hence:
a = 50000, b = 100% + 15% = 115% = 1.15
[tex]I(t) = 50000(1.15)^t[/tex]

A bottle contains 20 blue bags and 15 red bags. If two bags are picked at random one after the other with replacement, what is the probability that the first bag is blue and then red?
Answer:
12÷49Step-by-step explanation:
The total number of bags in the bottle = 20 + 15 = 35
Then
the probability that the first bag is blue = 20/35
If we replace the first bag :
the probability that the second (picked) bag is blue = 15/35
Conclusion:
If two bags are picked at random one after the other with replacement
Then
the probability that the first bag is blue and then red is :
(20÷35)×(15÷35)
= (4÷7)×(3÷7)
= 12÷49
= 0.244897959184

By applying the equation of dilation, the coordinates of the vertices of the triangle ABC are A'(x, y) = (-12, 0), B'(x, y) = (0, -9) and C'(x, y) = (-12, -9).
How to find the image of a triangle
A dilation is a type of rigid transformation. Rigid transformations are transformations applied to geometric loci such that Euclidean distances are conserved.
There is a triangle and its image must be a triangle, the new triangle is found by transforming the three vertices of the prior one following this formula:
A'(x, y) = P(x, y) + k · [A(x, y) - P(x, y)] (1)
Where:
P(x, y) - Center of reflection.A(x, y) - Original vertexA'(x, y) - New vertexk - Dilation factorIf we know that P(x, y) = (0, 0), A(x, y) = (-4, 0), B(x, y) = (0, -3) and C(x, y) = (-4, -3), then the new vertices of the triangle are, respectively:
Point A
A'(x, y) = (0, 0) + 3 · [(-4, 0) - (0, 0)]
A'(x, y) = (-12, 0)
Point B
B'(x, y) = (0, 0) + 3 · [(0, -3) - (0, 0)]
B'(x, y) = (0, -9)
Point C
C'(x, y) = (0, 0) + 3 · [(-4, -3) - (0, 0)]
C'(x, y) = (-12, -9)
Lastly, we draw the two triangles, which are presented in the image attached below.

brian runs 7 kilometers each day.write an equation that models the total kilometers,k,brian runs over,d, days
Answer:
k = 7d
Step-by-step explanation:
y = mx + b
slope (m): 7 kilometers each day
x: Brian runs over d days
y - intercept (b): when x = 0, y = 0 since it will be day 0
y: total kilometers, k
Answer:
k = 7d
Step-by-step explanation:
The standard form of an equation is :
y = mx + b
Here, the variables for y and x are k and d respectively.

Se dispone de un recipiente de 24 litros de capacidad y de tres medidas, A, B y C.
Se sabe que el volumen de A es el doble del de B, que las tres medidas llenan el
depósito y que las dos primeras lo llenan hasta la mitad. ¿Qué capacidad tiene cada
medida?
(Necesito saber el sistema de ecuaciones)
Teniendo en cuenta la definición de sistema de ecuaciones lineales, cada medida tiene una capacidad de A= 8 L, B= 4 L y C= 12 L.
Qué es un sistema de ecuacionesUn sistema de ecuaciones lineales es un conjunto de dos o más ecuaciones de primer grado, en el cual se relacionan dos o más incógnitas.
Resolver un sistema de ecuaciones consiste en encontrar el valor de cada incógnita para que se cumplan todas las ecuaciones del sistema. Es decir, se debe buscar los valores de las incógnitas, con los cuales al reemplazar, deben dar la solución planteada en ambas ecuaciones.
Capacidad de cada medidaEn este caso, se dispone de un recipiente de 24 litros de capacidad y de tres medidas, A, B y C.
Se sabe que el volumen de A es el doble del de B → A=2B
Las tres medidas llenan el depósito → A+ B +C= 24 L
Las dos primeras medidas llenan hasta la mitad del recipiente → A +B= 24 L÷2 → A +B= 12 L
Entonces, el sistema de ecuaciones a resolver es el formado por las tres ecuaciones anteriormente mencionadas.
Existiendo diversos métodos para resolver un sistema de ecuaciones, se decide resolver mediante el método de sustitución, que consiste en despejar una de las dos variables en una de las ecuaciones del sistema y sustituir su valor en la otra ecuación.
En este caso, reemplazando la primer ecuación en la tercera ecuación se obtiene:
2B +B= 12 L
3B= 12 L
B= 12 L÷3
B= 4 L
Reemplazando este valor en la primer ecuación se obtiene:
A=2B
A=2×4 L
A= 8 L
Finalmente, para obtener el valor de C se reemplaza el valor de A y B en la segunda ecuación:
A + B + C= 24 L
8 L + 4 L + C= 24 L
12 L + C= 24 L
C= 24 L - 12 L
C= 12 L
Finalmente, cada medida tiene una capacidad de A= 8 L, B= 4 L y C= 12 L.

Answer:
mean for data set 1 is 41
data set 1 MAD is 16.4
data set 2 MAD is 16.8
mean for data set 2 is 38
Step-by-step explanation:
Finding the mean:
Data set 1:formula: sum of the data set / total number of terms
sum of the data set: 18 + 29 + 35 + 58 + 65 = 205
total number of terms: there is 5 numbers in the data set
mean = 205 / 5
mean = 41
MAD (Mean Absolute Value):
step 1: Find the mean of the data (above)
step 2: Find the distance between each data and mean.
18, 29, 35, 58, 65
Distance between 18 and 41 is 23 (41 - 18 = 23)
Distance between 29 and 41 is 12 (41 - 29 = 12)
Distance between 35 and 41 is 6 (41 - 35 = 6)
Distance between 58 and 41 is -17 (41 - 58 = -17)
Distance between 65 and 41 is -24 (41 - 65 = -24)
step 3: take the absolute value of any negative numbers
|-17| and |-24| is 17 and 24
step 4: add all the distances
23 + 12 + 6 + 17 + 24 = 82
step 5: divided it by the number of data
82 / 5 = 16.4
Data set 2:
formula: sum of the data set / total number of terms
sum of the data set: 19 + 26 + 27 + 45 + 73 = 190
total number of terms: there is 5 numbers in the data set
mean = 190 / 5
mean = 38
MAD (Mean Absolute Value):
step 1: Find the mean of the data (above)
step 2: Find the distance between each data and mean.
19, 26, 27, 45, 73
Distance between 19 and 38 is 19 (38 - 19 = 19)
Distance between 26 and 38 is 12 (38 - 26 = 12)
Distance between 27 and 38 is 11 (38 - 27 = 11)
Distance between 45 and 38 is -7 (38 - 45 = -7)
Distance between 73 and 38 is -35 (38 - 73 = -35)
step 3: take the absolute value of any negative numbers
|-7| and |-35| is 7 and 35
step 4: add all the distances
19 + 11 + 12 + 7 + 35 = 84
step 5: divided it by the number of data
84 / 5 = 16.8
