how did the probability of drawing a green marble change from when ginny drew her marbles to when carter will draw?
Without specific information about the number of green marbles drawn by Ginny and Carter, we cannot determine how the probability of drawing a green marble changed between the two situations.
The probability of drawing a green marble can only be determined if we have information about the total number of marbles and the number of green marbles in each situation.
In the given question, no such information is provided. Therefore, we cannot analyze or compare the probability of drawing a green marble between Ginny's and Carter's situations.
To calculate the probability of an event, we need to know the number of favorable outcomes (in this case, the number of green marbles) and the total number of possible outcomes (the total number of marbles). Without this data.
It is impossible to quantify the change in probability between the two scenarios. It is essential to have specific details about the marbles drawn or the proportions of green marbles to make any meaningful comparisons or calculations regarding probability changes.

when a new charter school opened in 1994, there were 360 students enrolled. write a formula for the function n ( t ) , representing the number of students attending this charter school t years after 1994, assuming that the student population:
n(t) = 360 * 1.05^t. This formula assumes the growth rate of the student population remains constant at 5% per year. In reality, the growth rate may vary from year to year depending on various factors such as the school's reputation, enrollment policies, and local demographics
The formula for the function n(t) is based on the assumption that the student population grows by 5% per year. To calculate the number of students attending the charter school t years after 1994, we start with the initial number of students in 1994, which is 360, and then multiply it by 1.05 raised to the power of t.
For example, if we want to know how many students are attending the school in 2023 (29 years after 1994), we plug in t=29 into the formula:
n(29) = 360 * 1.05^29
≈ 1,188 students
This formula assumes that the growth rate of the student population remains constant at 5% per year. In reality, the growth rate may vary from year to year depending on various factors such as the school's reputation, enrollment policies, and local demographics. However, the formula provides a useful estimate of the school's enrollment over time based on a simple, consistent assumption.

María tiene en su libreta de ahorros un capital de 123.000,si deposita el día lunes la cantidad de 12.670 .El día miércoles por una urgencia , realiza un giro de 56.000¿cual es el nuevo capital que posee? Escribe la operación utilizando números enteros
Answer:
$79.670.
Step-by-step explanation:
Dado que María tiene en su libreta de ahorros un capital de $ 123.000,si deposita el día lunes la cantidad de $12.670, y el día miércoles por una urgencia, realiza un giro de $56.000, para determinar cuál es el nuevo capital que posee se debe realizar el siguiente cálculo:
123.000 + 12.670 - 56.000 = X
135.670 - 56.000 = X
79.670 = X
Así, el nuevo capital que María posee en su cuenta es de $79.670.

Silly answers will not be tolerated
Answer:
27a + 9b + c is reminder
Step-by-step explanation:
Remainder theorem says that when p(x) is divided by (x – a) the remainder is given
by p(a)
Let p(x) = ax³ + bx²+ c
P(x) when divided by (x – 3)
Using Remainder theorem, we have
Remainder = p(3) = a(3³) + b(3²) +c
= 27a + 9b + c
What number is halfway between -38.7 and -38.71?
Answer:
the answer to this question is -77.41
A)40%
B)45%
C)5%
D)10%
Answer:
A) 40%
Step-by-step explanation:
25% of yards have 6-8 trees; 10% of yards have 8-10 trees; 5% of yards have more than 10 trees. So, a total of 25% +10% +5% = 40% of yards have 6 trees or more. If a yard is randomly chosen, the probability it will have 6 or more trees is 40%.
Start with the base. What is the approximate base of the water tower. Use 3. 14 pi tower Height 20 feet radius 25 feet
The approximate base of the water tower is 1962.5 square feet.
Given: Height of the tower = 20 feet
Radius of the tower = 25 feet
Approximate value of π = 3.14
We need to find the approximate base of the water tower.
As we know that the base of the water tower is a circular base. The formula for the area of the circle is given byπr²
Where,
π = 3.14
r = radius of the circle = 25 feet
∴ Area of the circular base = 3.14 × (25)²= 3.14 × 625 = 1962.5 square feet
Therefore, the approximate base of the water tower is 1962.5 square feet.

Monica's age is 20 years and her father's age is 52
What is Simultaneous equation?Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time. For example, below are some simultaneous equations: 2x + 4y = 14 4x − 4y = 4.
Represent Monica's age by x and her father's age by y
y -x = 32 equation 1
y-16= 9(x-16)
= y-16 = 9x -144
y-9x = -144+16
y - 9x = -128 equation 2
subtract equation 2 from 1
-x-( -9x )= 32-(-128)
8x = 160
x = 160/8
x = 20
substitute 20 for x in equation 1
y = 32+x
y = 32+20
y = 52
Therefore Monica's age is 20 and her father's age is 52

Answer:
∠ T = 144°
Step-by-step explanation:
let ∠ S = x then ∠ T = 4x ( 4 times ∠ S )
Since the angles are supplementary, then they sum to 180° , that is
x + 4x = 180
5x = 180 ( divide both sides by 5 )
x = 36
Then ∠ S = 36° and ∠ T = 4 × ∠ S = 4 × 36° = 144°

The area of the figure can be obtained by applying the following relationship:
\(Area_{paralle\log ram}=base\cdot height\)Where b=base and height=h
In order to find the height, we need to apply the trigonometric relationship:
\(\sin 45=\frac{opposite}{\text{hypotenuse}}=\frac{height}{\text{diagonal}}=\frac{h}{6.4}\)Multiplying both sides by 6.4:
\(6.4\cdot\sin 45=h\)Solving the argument:
\(6.4\cdot0.65=h\)Switching sides:
\(h=4.16\text{ inches}\)Now that we have the height, we can compute the area as follows:
\(\text{Area}_{\text{parallelogram}}=12.8in\cdot4.16in=53.24in^2\)The answer is 53.24 squared inches.

How do you find the Cholesky decomposition of identity matrix
The Cholesky decomposition of the identity matrix is simply the identity matrix itself
The Cholesky decomposition of the identity matrix is simply the identity matrix itself. To see why this is the case, recall that the Cholesky decomposition of a matrix A is a lower-triangular matrix L such that
A = LL^T.
When A is the identity matrix I, we have I = LL^T.
Since L is lower-triangular, its transpose L^T is upper-triangular. Therefore, the only way for LL^T to be the identity matrix I is for L to also be the identity matrix I.
In summary, the Cholesky decomposition of the identity matrix I is I itself.
