The annual income of Juan Vance is $12,955.17.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
In order to pay for Social Security and Medicare, the Federal Insurance Contributions Act(FICA) mandates payroll deductions from both employers and employees.
Given, Juan Vance's Weekly salary is $231.67.
∴ Annually Juan earns $(52×231.67) = $12,046.84.
FICA deducts 7.51% from it and then combines another 7.51% with the employee,
∴ The net annual income of Juan Vence is
= [{12046.84 - (7.51/100)×12046.84 + {(7.51 + 7.51)/100}×12046.84}]
= (12046.84 - 904.71 + 1813.04}.
= $12,955.17

Explain the Triangle Inequality Theorem as it relates to angles.
Answer:
The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. In other words, the length of one side of a triangle must always be shorter than the sum of the lengths of the other two sides. This theorem is often used in geometry to determine whether or not a given set of lines can form a triangle.
When it comes to angles, the Triangle Inequality Theorem can be used to determine whether or not a triangle can be formed given the measures of its angles. For example, if the measures of two angles in a triangle are 45 degrees and 60 degrees, the measure of the third angle must be less than 180 degrees - 45 degrees - 60 degrees, or 75 degrees. If the measure of the third angle is greater than 75 degrees, it is not possible for the three angles to form a triangle.
Overall, the Triangle Inequality Theorem is a useful tool for understanding the relationships between the sides and angles of a triangle, and for determining whether or not a given set of lines or angles can form a triangle.

The speed of a runner increased steadily during the first three seconds of a race. her speed at half-second intervals is given in the table. find lower and upper estimates for the distance that she traveled during these three seconds.
t(s) 0 0.5 1.0 1.5 2.0 2.5 3.0
V (ft/s) 0 6.2 10.8 14.9 18.1 19.4 20.2
She can only move a certain distance in three seconds, with a lower distance of 33.45 feet and a upper distance of 43.45 feet.
The first three seconds of a race saw a runner's speed rapidly grow.
The time is therefore 3 seconds.
The table provides her speed at half-second intervals.
We are aware,
Speed = Distance / Time
Similarly
Distance = Speed × Time
t equals 0.5 seconds
Then, the lower distance traveled overall is equal to 0.5(0 + 6.7 + 9.2 + 14.1 + 17.5 + 19.4).
Terms are multiplied and added.
= 0.5 × 66.9
= 33.45 feet
The upper distance traveled is equal to 0.5 (6.7 + 9.2 + 14.1 + 17.5 + 19.4 + 20)
= 0.5 × 86.9
= 43.45 feet
As a result, Her lower distance in three seconds is therefore 33.45 feet, and her upper distance in three seconds is 43.45 feet.

there are six balls in a box if we select three balls what is the probability of having one white ball
The probability of having one white ball is 1/20 or approximately 0.05.
To find the probability of selecting one white ball out of three balls, you need to know the number of white balls in the box and the total number of balls in the box. You also need to know whether the balls are being selected randomly or not.
Assuming that there is only one white ball in the box and the rest are some other color, and that the balls are being selected randomly.
The probability of selecting one white ball out of three would be:
Probability = (number of ways to select one white ball out of three) / (total number of ways to select three balls)
Since there is only one white ball, there is only one way to select one white ball out of three. The total number of ways to select three balls out of six is 6 choose 3, which is equal to 20.
Therefore, the probability of selecting one white ball out of three would be
Probability = (number of ways to select one white ball out of three) / (total number of ways to select three balls)

What is surface area of a cuboid?The surface area of a cuboid is the total space occupied by it. A cuboid is a six-faced three-dimensional shape in which each face is in the shape of a rectangle.
Given that, a cuboid has volume of 120 cm³ and the area of the base of the cuboid is 30 cm².
We know that, the volume of cuboid is l×b×h.
Here, l×b=30
Now, 30×h=120
h=4 cm
We know that, surface area of the cuboid is 2(lb+bh+hl)
= 2(30+h(b+l))
= 2(30+4(b+l))

Pair of factors of 30 are
2×15=30
3×10=30
5×6=30
So, the possible surface area is
2(30+4(2+17))
= 2×106
= 212 cm²
2(30+4(3+10))
= 2×82
= 164 cm²

The ratio of reeta and neha income is 8:6. If reeta income is 2800. Find the income of neha
Answer: I don't believe the explanation above provides the correct answer. You would need to use the concept of proportions to solve this problem. The Answer I got is 2100.
Step-by-step explanation:
It is very simple all you have to do is setup a proportion with Reena's on top and Neha's on the bottom.
8/6 = 2800/x
Now cross multiply,
2800 * 6 = 8x
x=16800/8
x=2100
Now we can double-check by dividing the original ratio with the ratio we found.
8/6 = 1.3333333...
2800/2100 = 1.333333...
Thus, the answer is correct.

A mountain in jackson county is eroding and losing elevation at a rate of 5% every millennium. If the current elevation is 1,300 meters, how tall will the mountain be in 8 millennia?.
So the mountain will be approximately 798.02 meters tall after 8 millennia.
The mountain loses 5% of its elevation every millennium, which is the same as losing 0.05 * its current elevation. Therefore, after 1 millennium, the mountain's elevation will be 1 - 0.05 = 0.95 times its current elevation. After 2 millennia, it will be 0.95 * 0.95 = 0.9025 times its current elevation, and so on.
After 8 millennia, the mountain's elevation will be 0.95^8 times its current elevation. We can calculate this as follows:
Elevation after 8 millennia = 1,300 meters * 0.95^8
= 1,300 meters * 0.6134
= approximately 798.02 meters
So the mountain will be approximately 798.02 meters tall after 8 millennia.

if two distinct numbers are chosen at random from the set {1, 5, 10, 100} what is the probability that their sum will be greater than 100?
can someone save my grades and ego and explain this
please!
The probability of having the sums that would exceed 100 has been calculated to be 0.5
How to solve for the probabilityWe have the set or the sample space as:{1 , 5 , 10 , 100) It is said that two numbers would be able to be gotten from the set that we have. Given that the total numbers are 4, we would have ⁴C₂ = 6
The two numbers would be gotten from the set of 4 numbers in 6 different ways.
We are to find the numbers which when we add them up would be able to give us a sum that is greater than 100 these values are (100, 1), (100, 5), (100, 10)
Hence three pairs out of the given six that we already have would be able to give us values that are more than 10. We would have to divide through such that 3 / 6 = 1 / 2 = 0.5
Hence the probability that their values when summed would have to be greater than 100 is 0.5

A curve has equation y = x³ + ax + b.
The stationary points of the curve have coordinates (2, k) and (-2, 10-k).
Work out the value of a, the value of b and the value of k.
The value of 'a' is equal to -12, the value of 'b' is equal to 5 and the value of 'k' is equal to -11.
The stationary points of a curve are those points at which the first derivative of the function f(x) becomes zero. At the stationary points, the nature of the function is neither increasing nor decreasing.
→ The stationary points of a curve can either be a local minima or a local maxima of the function.
→ If we plot the graph of the curve, then stationary points can be said to be those points at which the tangent to the curve becomes horizontal which means the tangent becomes parallel to the x-axis.
→ Therefore for a point (a,b) to be the stationary point of a function f(x): f'(a) must be equal to zero.
→ For the given question:
f(x) = y = x³ + ax + b
f'(x) = 3x² + a
(2, k) is a stationary point:
f'(2) = 0
f'(2) = 3(2)² + a = 0
a = -12
The value of 'a' comes out to be equal to -12.
→ Hence the equation of the curve is: y = x³ - 12x + b
→ The stationary points (2, k) and (-2, 10-k) must be lying on the curve, hence they must satisfy the equation of the curve:
→ Putting (2, k) in the equation of the curve:
k = (2)³ - 12(2) + b
(k - b) = -16 - Equation (i)
→ Putting (-2, 10 - k) in the equation of the curve:
(10 - k) = (-2)³ -12(-2) + b
(10 - k) = -8 + 24 + b
b = -6 - k - Equation (ii)
→ Putting the value of 'b' from the equation (ii) in equation (i):
k - (-6 - k) = -16
k + 6 + k = -16
2k = -22
k = -11
∴ The value of 'k' comes out to be equal to -11.
→ Putting the value of 'k' in equation (i):
k - b = -16
-11 - b = -16
b = 5
∴ The value of 'b' comes out to be equal to 5.
Therefore, the value of 'a' is equal to -12, the value of 'b' is equal to 5 and the value of 'k' is equal to -11.

What is Hypothesis?
A hypothesis is an educated guess while using reasonable thinking, about the answer to a scientific question. Although it is not proof in an experiment, it is the predicted outcome of the experimentation. It can either be supported or not supported at all, but it depends on the data gathered.
The hypotheses for the test in this case are:
Null hypothesis (H0): The mean number of credit hours taken by all UCF students is not significantly different from 11 hours.
Alternative hypothesis (H1): The mean number of credit hours taken by all UCF students is significantly greater than 11 hours.
The null hypothesis represents the assumption that there is no difference between the mean number of credit hours taken by all UCF students and the value being tested (in this case, 11 hours). The alternative hypothesis is the opposite of the null hypothesis, and represents the claim that the mean number of credit hours taken by all UCF students is significantly different from 11 hours.
In this case, the instructor is specifically interested in testing whether the mean number of credit hours taken by all UCF students is significantly greater than 11 hours. Therefore, the alternative hypothesis is that the mean number of credit hours taken by all UCF students is significantly greater than 11 hours.

p varies directly with T and p = 400. When T = 500. Find the value of p when T = 600
Answer:
Step-by-step explanation:
When the temperature T is 500, the pressure p is 400. If we let "k" represent the constant of proportionality that relates p and T, then we can write the relationship between p and T as:
p = k * T
Substituting the known values of p and T into this equation, we get:
400 = k * 500
Solving for the constant of proportionality k, we find that:
k = 400/500 = 0.8
Now that we know the value of the constant of proportionality k, we can use it to find the value of p when T = 600. Substituting this value of T into the equation above and solving for p, we get:
p = 0.8 * 600 = 480
Therefore, when T = 600, the pressure p is 480.

B = [13, 36, 27,
10, 15, 0,
23, 51, 27].
The matrix that shows the total value of each cap size in each location is given as follows:
C = [247, 684, 513,
190, 285, 0,
437, 969, 513].
How to define the matrix B?The matrix B is defined considering that it will have three rows and three columns, as follows:
Row 1: Number of each type of cap on the store shelves.Row 2: Number of each type of cap on the stockroom.Row 3: Total number of each type of car -> Row 1 + Row 2.Column 1: Small caps.Column 2: Medium caps.Column 3: Large caps.Then the matrix B is defined as follows:
B = [13, 36, 27,
10, 15, 0,
23, 51, 27].
The cost of each baseball cap is of $19, thus the cost matrix is obtained multiplying the matrix B by the constant of 19.
When a matrix is multiplied by a constant, all the elements of the matrix are multiplied by the constant, hence the cost matrix is given as follows:
C = [247, 684, 513,
190, 285, 0,
437, 969, 513].
