Bruno had a gross income of $4925 during each pay period last year. If he got
paid monthly, how much of his yearly pay was deducted for FICA?
A. $4521.15
B. $3250.50
C. $3871.05
D. $3841.50
The amount of Bruno's yearly pay deducted for FICA is approximately
A. $4,524.15. The closest option provided is A. $4521.15.
To calculate the amount of FICA deducted from Bruno's yearly pay, we need to consider the specific FICA tax rates for Social Security and Medicare.
As of 2021, the Social Security tax rate is 6.2% on income up to a certain threshold, and the Medicare tax rate is 1.45% on all income.
Given that Bruno's gross income per pay period is $4925 and he is paid monthly, we can calculate the yearly gross income as follows:
Yearly gross income = $4925 * 12 = $59,100
To calculate the FICA deduction, we need to find the sum of the Social Security and Medicare taxes. Using the respective tax rates mentioned earlier:
Social Security deduction = $59,100 * 6.2% = $3,667.20
Medicare deduction = $59,100 * 1.45% = $856.95
Adding these two deductions together:
FICA deduction = $3,667.20 + $856.95 = $4,524.15
Therefore, the amount of Bruno's yearly pay deducted for FICA is approximately $4,524.15.
The closest option provided is A. $4521.15.

L is the midpoint of KM. If KL = 14x and KM = 26x + 14, what is KL? Simplify your answer and write it as a proper fraction, mixed number, or integer. Please type the answer step by step.
Answer:
Step-by-step explanation:
L is the midpoint of KM. So, length of KL = length of LM
KL = LM = 14x
KL + LM = KM
14x + 14x = 26x + 14 {add the like terms}
28x = 26x + 14 {subtract 26x form both sides}
28x - 26x = 14
2x = 14 {divide both side by 2}
2x/2 = 14/2
x = 7
KL = 14x = 14*7
KL = 98

If she sells 8 sets and she makes $2.25; write an equation in point-slope form representing her weekly possible earnings.answer choicesy - 2.25 = 0.75(x - 8)y - 8 = 0.75(x - 2.25)y - 8 = 2.25(x - 0.75)y - 0.75 = 2.25(x - 8)
The answer to this Question based on website is
What is website?
It is form of storage of information in well ordered way
Solution:
As we know she earns 0.75$ per set she sells in her website
and she sold 8 sets
hence total money he could earned = 8*0.75 = $6
but she made only = 2.25$ because remaining money she paid as website fee which was 6 - 2.25 = 3.75$
hence each week she has to pay 3.75$ as website fee so we can calculate his profit equation as follows
profit = 0.75x - n/7(3.75)

salaries of nurses in southern california are normally distributed with a mean of $6250 and a standard deviation of $250. what is the probability the mean salary of 25 randomly selected nurses is below $6150 or is above $6350 a month
Step-by-step explanation:
z-score of X = 6150
\( \frac{6150 - 6250}{250} = - 0.4 \\\)
z-score of X = 6350
\( \frac{6350 - 6250}{250} = - 0.4\)
P(X<6150) + P(X>6350)
=P(z<-0.4) + P(z>-0.4)
=0.3446+0.3446
=0.6892
Kyle’s doctor told him that the z-score for his systolic blood pressure is 1.75. Which of the following is the best interpretation of this standardized score? The systolic blood pressure (given in millimeters) of males has an approximately normal distribution with mean µ = 125 and standard deviation σ = 14. If X = a systolic blood pressure score then X ~ N (125, 14).
a. Which answer(s) is/are correct?
1. Kyle's systolic blood pressure is 175.
2. Kyle's systolic blood pressure is 1.75 times the average blood pressure of men his age.
3. Kyle's systolic blood pressure is 1.75 above the average systolic blood pressure of men his age.
4. Kyles's systolic blood pressure is 1.75 standard deviations above the average systolic blood pressure for men.
b. Calculate Kyle's blood pressure.
Answer:
a. 4. Kyles's systolic blood pressure is 1.75 standard deviations above the average systolic blood pressure for men.
b. His blood pressure is of 149.5 millimeters
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:
\(Z = \frac{X - \mu}{\sigma}\)
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
a. Which answer(s) is/are correct?
His blood pressure has a zscore of 1.75, which means that it is 1.75 standard deviation above the mean value. So the correct answer is given by option 4.
b. Calculate Kyle's blood pressure.
We have to find X when \(Z = 1.75, \mu = 125, \sigma = 14\). So
\(Z = \frac{X - \mu}{\sigma}\)
\(1.75 = \frac{X - 125}{14}\)
\(X - 125 = 1.75*14\)
\(X = 149.5\)
His blood pressure is of 149.5 millimeters
The diameter of cork of a Champagne bottle is supposed to be 1.5 cm. If the cork is either too large or too small, it will not fit in the bottle. The manufacturer measures the diameter in a random sample of 36 bottles and finds their mean diameter to be 1.4 cm with standard deviation of 0.5 cm. Is there evidence at 1% level that the true mean diameter has moved away from the target?
Answer:
\(t_{n-1,\alpha/2}=3.59114678\)
Therefore we do not have sufficient evidence at \(1\%\) level that the true mean diameter has moved away from the target
Step-by-step explanation:
From the question we are told that:
Sample size \(n=36\)
Mean diameter \(\=x=1.4\)
Standard deviation \(\sigma=0.5cm\)
Null hypothesis \(H_0 \mu=1.5\)
Alternative hypothesis \(\mu \neq 1.5\)
Significance level \(1\%=0.001\)
Generally the equation for test statistics is mathematically given by
\(t=\frac{\=x-\mu}{\frac{s}{\sqrt{n} } }\)
\(t=\frac{1.4-1.5}{\frac{0.5}{\sqrt{36} } }\)
\(t=-1.2\)
Therefore since this is a two tailed test
\(t_{n-1,\alpha/2}\)
Where
\(n-1=36-1=>35\)
\(\alpha=/2=0.001/2=>0.0005\)
From table
\(t_{n-1,\alpha/2}=3.59114678\)
Therefore we do not have sufficient evidence at \(1\%\) level that the true mean diameter has moved away from the target
Adam has $450. He spends $210 on food. Later he divides all the money into four parts out of
which three parts were distributed and one part he keeps for himself. Then he found $50 on
the road.
Answer: $110
Step-by-step explanation:
Adam would have $110. Subtract 210 from 450 to get how much money he has after shopping for food. 450 - 210 = 240. Divide 240 by 4 because he distributed his money into 4 parts. 240 / 4 = 60. He keeps one fourth of the 240, so he keeps $60. He finds $50 on the road, so 40 + 50 = 110. He has $110 in the end.

The amount natalya will spend constructing the patio with concrete and brick is $4320, the correct option is D.
We are given that;
The concrete portion of the patio cost=$3 per square
To construct and the brick portion of the patio cost= $6 per square
Now,
The area of a rectangle is given by length times width. The concrete portion of the patio is a rectangle with length 6 cm and width 3 cm. Using the scale, we can convert these to feet:
6 cm = 6 x 4 ft = 24 ft 3 cm = 3 x 4 ft = 12 ft
Therefore, the area of the concrete portion is:
24 ft x 12 ft = 288 ft^2
The brick portion of the patio consists of two identical rectangles with lenth 3 cm and width 6 cm. Using the scale, we can convert these to feet:
3 cm = 3 x 4 ft = 12 ft 6 cm = 6 x 4 ft = 24 ft
Therefore, the area of one brick rectangle is:
12 ft x 24 ft = 288 ft^2
Since there are two brick rectangles, the total area of the brick portion is:
2 x 288 ft^2 = 576 ft^2
Now we can multiply the areas by their costs per square foot to get the costs of each portion:
Concrete cost = $3 x 288 ft^2 = $864 Brick cost = $6 x 576 ft^2 = $3456
The total cost of constructing the patio is the sum of the costs of each portion:
Total cost = $864 + $3456 = $4320
Therefore, by area the answer will be $4320.

The Pythagorean theorem states that in a right triangle, the square of the hypotenuse = sum of the squares of the legs.
We have,
The Pythagorean theorem that relates to the sides of a triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides (known as the legs). Mathematically, it can be expressed as a² + b² = c², where "a" and "b" are the lengths of the legs, and "c" is the length of the hypotenuse.
Now,
In a right triangle, the legs are the two sides that form the right angle, and the hypotenuse is the side that is opposite to the right angle. The Pythagorean theorem states that in a right triangle, the square of the hypotenuse = sum of the squares of the legs. So, the relationship between the legs and the hypotenuse can be described by this theorem. In other words, if we know the length of the two legs of a right triangle, we can use the Pythagorean theorem to find the length of the hypotenuse, and vice versa. The hypotenuse is always the longest side of the right triangle, and it is also the side that connects the two legs.
