Alisha Gregory is a telephone installer. She is married and claims 2 allowances. Her state
personal exemptions total $76. 92 per week. The state tax rate is 3. 0% of taxable income.
Local income tax is 1. 5% of gross. Medical insurance costs $1,940 a year, of which the
company pays 60%. Her gross weekly pay is $640. She pays $4. 50 in union dues and $7. 50 in
other. Find the following:
a) FIT
b) FICA (Social Security)
c) Medicare
d) State
e) Local
f) Medical
g) Total Deductions
h) Net Pay
a) FIT: $16.89
b) FICA: $39.68
c) Medicare: $9.28
d) State: $19.20
e) Local: $9.60
f) Medical: $14.92
g) Total Deductions: $121.57
h) Net Pay: $518.43.
a) FIT (Federal Income Tax): To calculate the FIT, we need to determine the taxable income first. Alisha's gross weekly pay is $640, and she has the following deductions: union dues ($4.50) and other ($7.50). So her total deductions are $4.50 + $7.50 = $12.
Her taxable income is her gross pay minus the total deductions: $640 - $12 = $628.
To find the FIT, we multiply the taxable income by the FIT rate. Since the question does not provide the FIT rate, I cannot calculate the exact amount of FIT. However, the FIT rate is determined by a progressive tax system, which means the rate increases as the income increases.
b) FICA (Social Security): FICA is a federal payroll tax that is used to fund Social Security and Medicare programs. The FICA rate for Social Security is currently 6.2% of the gross income. To calculate the FICA for Alisha, we multiply her gross income of $640 by 6.2% (0.062). The result will be the amount deducted for Social Security.
c) Medicare: The Medicare tax rate is 1.45% of the gross income. To calculate the Medicare tax for Alisha, we multiply her gross income of $640 by 1.45% (0.0145). The result will be the amount deducted for Medicare.
d) State: The state tax rate is given as 3.0% of taxable income. To calculate the state tax, we multiply the taxable income (which we calculated earlier as $628) by 3.0% (0.03).
e) Local: The local income tax rate is given as 1.5% of the gross income. To calculate the local tax, we multiply the gross income of $640 by 1.5% (0.015).
f) Medical: The question states that Alisha's medical insurance costs $1,940 per year, of which the company pays 60%. To find the amount she pays for medical insurance, we multiply the total cost by the percentage she pays: $1,940 * (1 - 0.60) = $776.
g) Total Deductions: The total deductions are the sum of all the deductions, including FIT, FICA, Medicare, state, local, and medical.
h) Net Pay: The net pay is the gross income minus the total deductions.
Please note that without specific information about the FIT rate, I cannot provide an exact calculation for FIT. Additionally, I have not included any additional deductions or allowances that Alisha may have. This answer is based solely on the information provided in the question.

AP Statistics TPS 8.3Q. Which of the following changes to a study would result in a narrower confidence interval?answer choices- increasing the confidence level, increasing the sample size- decreasing the confidence level, decreasing the sample size- increasing the confidence level, decreasing the sample size- decreasing the confidence level, increasing the sample size.
Answer:
Step-by-step explanation:
The correct answer is decreasing the confidence level, increasing the sample size.
A narrower confidence interval means that the range of possible values for the true population parameter is smaller, indicating greater precision in the estimate.
Increasing the sample size will increase the precision of the estimate of the population parameter, thus resulting in a narrower confidence interval.
On the other hand, decreasing the confidence level will also result in a narrower interval. Since the confidence interval represents a range of values that are likely to contain the true population parameter, a lower confidence level means that there is less uncertainty in the estimate of the population parameter, which leads to a narrower interval.
Increasing the sample size and lowering the confidence level are the correct responses.
A narrower confidence interval denotes more accuracy in the estimate because it reduces the range of potential values for the true population parameter.
A narrower confidence interval will be produced by increasing the sample size because it will improve the estimate of the population parameter's precision.
On the other hand, a narrower interval will be produced by lowering the confidence level. A lower confidence level indicates that there is less uncertainty in the estimate of the population parameter, which results in a narrower interval. The confidence interval reflects a range of values that are likely to contain the true population parameter.

the random vector (x, y ) has a joint pdf fxy (x, y) = 2e −x e −2y for x > 0, y > 0. find the probability of the following events:
a. {X + Y <=8}
The probability of the {X + Y ≤ 8} is 0.99933.
The random vector (x, y) has a joint pdf \(f_{xy}\)(x, y) = 2\(e^{-x}e^{-2y}\) for x > 0, y > 0.
We have to determine the probability of {X + Y ≤ 8}.
P{X + Y ≤ 8} = 1 - {X + Y > 8}
We can write it as
P{X + Y ≤ 8} = 1 - {X > 8 - Y}
P{X + Y ≤ 8} = 1 - \(\int^{\infty}_{0}\int_{8-y}^{\infty}f_{xy}(x, y)dxdy\)
P{X + Y ≤ 8} = 1 - \(\int^{\infty}_{0}\int_{8-y}^{\infty}2e^{-x}e^{-2y}dxdy\)
First integrate the function with respect to x
P{X + Y ≤ 8} = 1 - \(\int^{\infty}_{0}2e^{-2y}[e^{-x}]_{8-y}^{\infty}dy\)
P{X + Y ≤ 8} = 1 - \(\int^{\infty}_{0}2e^{-2y}[e^{-(8-y)}]dy\)
P{X + Y ≤ 8} = 1 - \(\int^{\infty}_{0}2e^{-2y-8+y}dy\)
P{X + Y ≤ 8} = 1 - \(2\int^{\infty}_{0}e^{-y-8}dy\)
P{X + Y ≤ 8} = 1 - \(2e^{-8}\int^{\infty}_{0}e^{-y}dy\)
P{X + Y ≤ 8} = 1 - \(2e^{-8}[-e^{-y}]^{\infty}_{0}\)
P{X + Y ≤ 8} = 1 - \(2e^{-8}[1-0]\)
P{X + Y ≤ 8} = 1 - 2e⁻⁸

. If R1 = {(x, y)| y = 2x + 7, where x∈ R and -5 ≤ x ≤ 5} is a relation. Then find the domain and range of R1.
Answer:
Domain is [-5, 5]
Range is [-3, 17]
Step-by-step explanation:
R1 = {(x, y)| y = 2x + 7, where x∈ R and -5 ≤ x ≤ 5}
The domain is given by the all possible input values of x . Here the function is defined for -5 ≤ x ≤ 5, so the domain is [ - 5, 5].

precalculus b dba given a vertical asymptote and a horizontal asymptote, how would you begin to find an expression for a rational function?
By finding the vertical and horizontal asymptotes, you can use them to help find an expression for the rational function
To find an expression for a rational function given a vertical asymptote and a horizontal asymptote, start by recognizing that the general form of a rational function is f(x) = (ax + b)/(cx + d), where a, b, c, and d are all constants.
Next, use the given information to solve for a, b, c, and d in the equation. The vertical asymptote represents the x-values at which the denominator of the equation equals zero, so set cx + d equal to zero and solve for x. Similarly, the horizontal asymptote can be found by setting ax + b equal to the asymptote’s y-value.
Once both equations are solved for x, substitute the x-values back into the equation for the rational function and solve for the corresponding a, b, c, and d values.
A vertical asymptote occurs when the denominator of the rational function is equal to zero, so you can set the denominator equal to zero and solve for the variable to find the vertical asymptote.
A horizontal asymptote occurs when the degree of the numerator and denominator are equal, so you can look at the leading coefficients of the numerator and denominator to find the horizontal asymptote.

Cost of moving possessions: $1,200
(This deduction applies if the move meets certain distance and time requirements. Since the move was 125 miles away, it meets the distance requirement.)
Interest paid on student loans: $2,890
Cost of purchasing a delivery uniform: $1,490
Cash contribution to State University deliveryman program: $1,345
Total deductible expenses:
$1,200 + $2,890 + $1,490 + $1,345
= $6,925
Now we can calculate Evan's AGI and taxable income:
AGI (Adjusted Gross Income)
= Total income - Deductible expenses
AGI = $74,350 - $6,925 = $67,425
Taxable Income = AGI - Standard Deduction
For a single filer in 2022, the standard deduction is $12,550.
Taxable Income = $67,425 - $12,550 = $54,875
Therefore,
Evan's AGI is $67,425 and his taxable income is $54,875 if he files as a single taxpayer.

Determine the inverse of the function f(x) = log3(4x + 5) − 6.
f inverse of x is equal to 3 to the power of the quantity x minus 6 end quantity plus 5 all over 4
f inverse of x is equal to 3 to the power of the quantity x plus 6 end quantity minus 5 all over 4
f inverse of x is equal to 3 to the power of x plus 4 all over 4
f inverse of x is equal to the quantity x plus 6 end quantity cubed minus 5 all over 3
The inverse of the function f(x) = log of (4x + 5) - 6 to the base 3 is f^-1(x) = [x^(y+6) -5]/4
Inverse of a functionA function is said to have an inverse if it is both one-to-one and onto
For the function f(x) = log of (4x + 5) - 6 to the base 3
we replace f(x) with y and make x the subject to arrive at the inverse f^-1(x) as follows;
y = log of (4x + 5) - 6 to the base 3
y + 6 = log of (4x + 5) to the base 3 {add 6 to both sides}
3^(y+6) = 4x + 5 {by law of logarithm which states that if the log of "a" to the base "b" is equal to "x", then a = b^x}
also;
4x + 5 = 3^(y+6)
4x + 5 - 5= 3^(y+6) - 5
{subtract 5 from both sides}
x= [3^(y+6) - 5]/4
so,
y = [3^(x+6) - 5]/4 and
f^-1(x) = [3^(x+6) - 5]/4
Hence, the inverse of the function f is derived by interchanging the value of x for y and vice versa, that is f^-1(x) = [3^(x+6) - 5]/4

is g(x) = x^ an exponential function?
Answer:
Yes
Step-by-step explanation:
Hi,
Since, in this case, x is being raised to something, then that means it is, in fact, an exponential function.

Here is a sample of amounts of weight change (kg) of college students in their freshman year: 15, 3, 2, -4 , where -4 represents a loss of 4 kg and positive values represent weight gained. Here are ten bootstrap samples:
{15, 15, 15, 2}, {15, -4, 2, 15}, {15, -4, 3, 2}, {3, -4, 2, 15}, {2, 2, 2, 3}, {3, -4, 3, -4}, {15, 3, 4, 2}, {-4, 3, -4, 3}, {-4, 2, 4, 3}, {3, 15, 15, 15}.
Using only the ten given bootstrap samples, construct an 80% confidence interval estimate of the mean weight change for the population.
kg<μ< kg
(Round to one decimal place as needed.)
the 80% confidence interval estimate of the mean weight change for the population is approximately 1.8 kg to 8.9 kg.
Given bootstrap samples:
Sample 1: {15, 15, 15, 2}
Sample 2: {15, -4, 2, 15}
Sample 3: {15, -4, 3, 2}
Sample 4: {3, -4, 2, 15}
Sample 5: {2, 2, 2, 3}
Sample 6: {3, -4, 3, -4}
Sample 7: {15, 3, 4, 2}
Sample 8: {-4, 3, -4, 3}
Sample 9: {-4, 2, 4, 3}
Sample 10: {3, 15, 15, 15}
Calculate the mean weight change for each sample.
Sample 1: Mean = (15 + 15 + 15 + 2) / 4 = 11.8
Sample 2: Mean = (15 - 4 + 2 + 15) / 4 = 7.0
Sample 3: Mean = (15 - 4 + 3 + 2) / 4 = 4.0
Sample 4: Mean = (3 - 4 + 2 + 15) / 4 = 4.0
Sample 5: Mean = (2 + 2 + 2 + 3) / 4 = 2.3
Sample 6: Mean = (3 - 4 + 3 - 4) / 4 = -0.5
Sample 7: Mean = (15 + 3 + 4 + 2) / 4 = 6.0
Sample 8: Mean = (-4 + 3 - 4 + 3) / 4 = -0.5
Sample 9: Mean = (-4 + 2 + 4 + 3) / 4 = 1.3
Sample 10: Mean = (3 + 15 + 15 + 15) / 4 = 12.0
Mean of Sample Means = (11.8 + 7.0 + 4.0 + 4.0 + 2.3 + (-0.5) + 6.0 + (-0.5) + 1.3 + 12.0) / 10 = 5.34
Standard Error = standard deviation / √(number of samples)
Given that the standard deviation is not provided, we will use the standard deviation of the original data set: 6.1 kg.
Standard Error = 6.1 / √10 = 1.93
The margin of Error = critical value * standard error
To find the critical value for an 80% confidence interval, we can refer to the t-distribution table or use a calculator. For a two-tailed test with 10 samples and an 80% confidence level, the critical value is approximately 1.833.
Margin of Error = 1.833 * 1.93 = 3.54
Lower Bound = Mean of Sample Means - Margin of Error
Lower Bound = 5.34 - 3.54 = 1.80
Upper Bound = Mean of Sample Means + Margin of Error
Upper Bound = 5.34 + 3.54 = 8.88
