Bailee's annual income was deducted for FICA is approximately C. $2,164.95.
How to Calculate Annual Income Deducted for FICA?FICA, or the Federal Insurance Contributions Act, is a payroll tax that is used to fund Social Security and Medicare. The current FICA tax rate for Social Security is 6.2% and the current rate for Medicare is 1.45%.
To find out how much of Bailee's annual income was deducted for FICA, we can multiply her gross income during each pay period by the FICA tax rate and the number of pay periods in a year.
Since Bailee gets paid monthly, there are 12 pay periods in a year.
FICA = (Gross income * (6.2% + 1.45%)) *12
FICA = (2358.33 * (6.2/100 + 1.45/100)) * 12
FICA = (2358.33 * 0.0765) * 12
FICA = 179.95 * 12
FICA = $2159.4
So, $2159.4 of Bailee's annual income was deducted for FICA.

Question:
There are 30 candies in a box, all identically shaped. 5 are filled with coconut, 10 with caramel, and 15 are solid chocolate.
You randomly select a piece of candy and eat it (so it is NOT replaced!), then select a second piece. Find the probability of each event
(a) The probability of selecting two solid chocolates in a row.
(b) The probability of selecting a caramel and then a coconut candy.
Answer:
\((a)\) \(P(Chocolates) = \frac{7}{29}\)
\((b)\) \(P(Caramel\ and\ Coconut) = \frac{5}{87}\)
Step-by-step explanation:
Given
\(Coconut = 5\)
\(Caramel = 10\)
\(Chocolate = 15\)
\(Total = 30\)
For probabilities without replacement, 1 is subtracted after the first selection.
So, we have:
Solving (a): Two solid chocolates
This is calculated as:
\(P(Chocolates) = P(First\ Chocolate) * P(Second\ Chocolate)\)
\(P(Chocolates) = \frac{n(Chocolate)}{Total} * \frac{n(Chocolate) - 1}{Total - 1}\)
\(P(Chocolates) = \frac{15}{30} * \frac{15 - 1}{30 - 1}\)
\(P(Chocolates) = \frac{15}{30} * \frac{14}{29}\)
\(P(Chocolates) = \frac{1}{2} * \frac{14}{29}\)
\(P(Chocolates) = \frac{7}{29}\)
Solving (a): Caramel and Coconut
This is calculated as:
\(P(Caramel\ and\ Coconut) = P(Caramel) * P(Coconut)\)
\(P(Caramel\ and\ Coconut) = \frac{n(Caramel)}{Total} * \frac{n(Coconut)}{Total - 1}\)
\(P(Caramel\ and\ Coconut) = \frac{10}{30} * \frac{5}{30- 1}\)
\(P(Caramel\ and\ Coconut) = \frac{10}{30} * \frac{5}{29}\)
\(P(Caramel\ and\ Coconut) = \frac{1}{3} * \frac{5}{29}\)
\(P(Caramel\ and\ Coconut) = \frac{5}{87}\)

A report states that 46% of home owners have a vegetable garden. How large a sample is needed to estimate the true proportion of home owners who have vegetable gardens to within 4 percentage points with 98% confidence?
The sample size needed to estimate the true proportion of home owners who have vegetable gardens to within 4 percentage points with 98% confidence is 1,529.
To calculate the sample size, we can use the formula:
n = (z² * p * q) / E²
Where:
- n is the sample size
- z is the z-score for the desired level of confidence (98% confidence corresponds to a z-score of 2.33)
- p is the expected proportion of home owners who have vegetable gardens (0.46 based on the report)
- q is 1-p (0.54)
- E is the margin of error (0.04)

A box contains 9 plain pencils and 3 pens. A second box contains 1 color pencil and 7 crayons. One item from each box is chosen at random. What is the probability that a plain pencil from the first box and a color pencil from the second box are selected? Write your answer as a fraction in simplest form.
A regular pencil from the first package and a colored pencil from the second box can be chosen with a 3/32 chance.
What is a probability example?By reducing the number of positive outcomes even by total number of potential outcomes, probability—the chance that even an event will take place—can be determined. Only two results when users flip a coin: either it shows up heads or tails.
Since there are 9 plain pencils in the first package out of a total of 12 products, the chance of choosing one is 9/12.
Since there is only one color pencil in the second package out of a total of eight items, the chance of choosing one is 1/8.

Use matrix inversion to solve the given system of linear
equations. (You previously solved this system using row reduction.)
−x + 2y − z = 0 −x − y + 2z = 0 2x − z = 3 (x, y, z) =
The solution to the system of given linear equations using matrix inversion is (x, y, z) = (3, -3, -6).
The system of linear equations that needs to be solved is:
\($$\begin{aligned}-x+2y-z&=0\\-x-y+2z&=0\\2x-z&=3\end{aligned}\)
$$
To solve this system using matrix inversion, we first write the system in matrix form as AX = B, where
\($$A=\begin{bmatrix}-1 &2 &-1\\-1 &-1 &2\\2 &0 &-1\end{bmatrix}, X=\begin{bmatrix}x\\y\\z\end{bmatrix}, \text{and } B=\begin{bmatrix}0\\0\\3\end{bmatrix}$$\)
We then find the inverse of A as \(A^-^1\), such that \(A^-^1A\) = I, where I is the identity matrix. Then we have:
\($$A^{-1}=\begin{bmatrix}1 &2 &3\\-1 &-1 &-2\\-2 &-2 &-3\end{bmatrix}$$\)
Finally, we can solve for X using X = \(A^-^1B\) as follows:
\($$X=\begin{bmatrix}1 &2 &3\\-1 &-1 &-2\\-2 &-2 &-3\end{bmatrix}\begin{bmatrix}0\\0\\3\end{bmatrix}=\begin{bmatrix}3\\-3\\-6\end{bmatrix}$$\)
Therefore, the solution to the system of linear equations is (x, y, z) = (3, -3, -6).
From the above discussion, we found that the solution to the system of linear equations using matrix inversion is (x, y, z) = (3, -3, -6).
Matrix inversion is a method of solving a system of linear equations using matrix operations. It involves finding the inverse of the coefficient matrix A, which is a matrix such that when multiplied by A, the identity matrix is obtained. Once the inverse is found, the system can be solved using matrix multiplication as X = A^-1B.In the above example, we used matrix inversion to solve the system of linear equations. We first wrote the system in matrix form as AX = B, where A is the coefficient matrix, X is the vector of unknowns, and B is the vector of constants. We then found the inverse of A, A^-1, using matrix operations. Finally, we used X = A^-1B to solve for X, which gave us the solution to the system of linear equations.
From the above discussion, it is clear that matrix inversion is a useful method for solving systems of linear equations. It is particularly useful when the coefficient matrix is invertible, meaning that its determinant is nonzero. In such cases, the inverse can be found, and the system can be solved using matrix multiplication.

circle is 289 units2, and AB = 16 units.
Find BC and mBC.
B
A
C
E. plssss hurry !!
The measure of arc BC is 720 times the measure of angle BAC.
Given that AC is the diameter of the circle and AB is a chord with a length of 16 units, we need to find BC (the length of the other chord) and mBC (the measure of angle BAC).
To find BC, we can use the property of chords in a circle. If two chords intersect within a circle, the products of their segments are equal. In this case, since AB = BC = 16 units, the product of their segments will be:
AB * BC = AC * CE
16 * BC = 2 * r * CE (AC is the diameter, so its length is twice the radius)
Since the area of the circle is given as 289 square units, we can find the radius (r) using the formula for the area of a circle:
Area = π * r^2
289 = π * r^2
r^2 = 289 / π
r = √(289 / π)
Now, we can substitute the known values into the equation for the product of the segments:
16 * BC = 2 * √(289 / π) * CEBC = (√(289 / π) * CE) / 8
To find mBC, we can use the properties of angles in a circle. The angle subtended by an arc at the center of a circle is double the angle subtended by the same arc at any point on the circumference. Since AC is a diameter, angle BAC is a right angle. Therefore, mBC will be half the measure of the arc BC.
mBC = 0.5 * m(arc BC)
To find the measure of the arc BC, we need to find its length. The length of an arc is determined by the ratio of the arc angle to the total angle of the circle (360 degrees). Since mBC is half the arc angle, we can write:
arc BC = (mBC / 0.5) * 360
arc BC = 720 * mBC
Therefore, the length of the arc BC equals 720 times the length of the angle BAC.

find the limit. use l'hospital's rule if appropriate. if there is a more elementary method, consider using it. lim x→/2 (sec(x) − tan(x))
The required limit is 8/3.
To find the limit: lim(x→π/2) (sec(x) − tan(x)).
First, we check whether it is in an indeterminate form. Evaluating the limit directly, we have:
lim(x→π/2) (sec(x) − tan(x)) = sec(π/2) - tan(π/2) = 1/cos(π/2) - sin(π/2).
The denominator of the above expression approaches zero, indicating an indeterminate form of 0/0. Therefore, we can use L'Hôpital's Rule.
We differentiate the numerator and denominator separately and apply the limit again. Differentiating, we get:
lim(x→π/2) [d/dx(sec(x)) - d/dx(tan(x))] / [d/dx(x)] ... [Using L'Hôpital's Rule]
= lim(x→π/2) [sec(x)tan(x) + sec²(x)] / [1].
Putting the limit value, we have:
= sec²(π/2) + sec(π/2)tan(π/2).
We know that sec(π/2) = 1/cos(π/2) and tan(π/2) = sin(π/2)/cos(π/2).
Therefore, sec²(π/2) + sec(π/2)tan(π/2) = [1/cos²(π/2)] + [sin(π/2)/cos²(π/2)]
= [1 + sin(π/2)] / [cos²(π/2)].
Putting the value of π/2, we get:
[1 + sin(π/2)] / [cos²(π/2)] = [1 + 1/2] / [3/4]
= [3/2] * [4/3]
= 8/3.

Select the correct answer from each drop-down menu.
If Lily chooses account A, the balance of her account would increase by a rate of __
on a __ basis.
1. .024%
0.24%
2.4%
3%
4%
1.024%
2. monthly
yearly
quarterly
weekly
semi-annual
If Lily chooses account A, the balance of her account would increase by a rate of 2.4% on a quarterly basis
The EquationThe equation of the function is given as:
\(A(t) = 3000(1.024)^{4t\)
Exponential functionAn exponential function is represented as:
\(y = a(1 + r)^x\)
Where:
a represents the initial valuer represents the rateSo. by comparison:
\(1 + r=1.024\)
Subtract 1 from both sides
\(r=.024\)
Express as percentage
\(r=2.4\%\)
From the function, the exponent of the rate is 4t.
This means that, the balance increases four times in a year.
So, her balance would increase quarterly
