A level machine is used to perform the differential leveling between a benchmark and a target point with a closed loop, and get four backsight values as 7.85 ft, 3.55 ft, 4.51 ft and 5.01 ft and four foresight values as 5.57 ft, 3.87 ft, 5.15 ft and 6.11 ft What is the error of closure (EC)? a) None of the given answers b) -0.22 ft Oc) 0.22 ft d) 0.06 ft e) -0.06 ft
The error of closure (EC) is a measure of the accuracy of a closed loop leveling survey.
To calculate the error of closure, we need to subtract the sum of the foresight values from the sum of the backsight values. In this case, the sum of the backsight values is (7.85 ft + 3.55 ft + 4.51 ft + 5.01 ft) = 20.92 ft, and the sum of the foresight values is (5.57 ft + 3.87 ft + 5.15 ft + 6.11 ft) = 20.70 ft.
The error of closure (EC) can be obtained by subtracting the sum of the foresight values from the sum of the backsight values: EC = (sum of backsight values) - (sum of foresight values) = 20.92 ft - 20.70 ft = 0.22 ft.
Therefore, the correct answer is c) 0.22 ft, which represents the error of closure in this leveling survey.

Please Help! 60 points for a rapid reply- please look at the question below= The Figure of circle A shown has a diameter of PR which intersects with QS at point B and the measurements shown, Calculate the following measures-
The measures in the circle given in the image above are calculated as:
1. m<PSQ = 130°; 2. m<AQS = 30°; 3. m(QR) = 100°; 4. m(PS) = 110°; 5. (RS) = 70°.
How to Find the Measures in the Circle?In order to find the measures in the circle shown, recall that according to the inscribed angle theorem, the measure of intercepted arc is equal to the central angle, but is twice the measure of the inscribed angle.
1. m<PSQ = m<PAQ
Substitute:
m<PSQ = 130°
2. Find m<PBQ:
m<PBQ = 1/2(m(PQ) + m(RS)) [based on the angles of intersecting chords theorem]
Substitute:
m<PBQ = 1/2(130 + 2(35))
m<PBQ = 100°
m<AQS = 180 - [m<BAQ + m<PBQ]
Substitute:
m<AQS = 180 - [(180 - 130) + 100]
m<AQS = 30°
3. m(QR) = m<QAR
Substitute:
m(QR) = 100°
4. m(PS) = 180 - m(RS)
Substitute:
m(PS) = 180 - 2(35)
m(PS) = 110°
5. m(RS) = 2(35)

What are fractions?A fraction is a mathematical unit used to represent a portion of a whole or a ratio of two integers. They are shown as the top number, or numerator, and the bottom number, or denominator, separated by a line. The denominator is the total number of pieces that make up the whole, whereas the numerator is the number of shares or parts.
For instance, you may write 3/8 for the portion of pizza you consumed if there were 8 pieces and you only ate 3. This indicates that you consumed three of the pizza's eight equally sized portions.
From the given table we can determine the total number of votes are:
13 + 9 + 10 + 8 + 10 + 14 + 5 + 6 = 75.

find the taylor series for f centered at 7 if f (n)(7) = (−1)nn! 2n(n 1) .
Therefore, the Taylor series for f centered at 7 is given by: \(f(x) = (-1)^n * n! * 2^n * (n-1) + (-1)^n * n! * 2^{(n-1)} * (n-1) * (n-2) * (x-7) + (-1)^n * n! * 2^{(n-1)} * (n-1) * (n-2) * (n-3) * (n-4) * (x-7)^2/2 + (-1)^n * n! * 2^{(n-1)} * (n-1) * (n-2) * (n-3) * (n-4) * (n-5) * (n-6) * (x-7)^3/6 + ...\)
To find the Taylor series for f centered at 7, we can use the formula for the Taylor series expansion:
\(f(x) = f(c) + f'(c)(x-c) + (f''(c)(x-c)^2)/2! + (f'''(c)(x-c)^3)/3! + ...\\f(x) = f(c) + f'(c)(x-c) + (f''(c)(x-c)^2)/2! + (f'''(c)(x-c)^3)/3! + ...\\f'(x) = -(-1)^n * n! * 2^{(n-1)} * (n-1) * (n-2) * (x-7)^{(n-3)}\\f''(x) = -(-1)^n * n! * 2^{(n-1)} * (n-1) * (n-2) * (n-3) * (n-4) * (x-7)^{(n-5)}\\f'''(x) = -(-1)^n * n! * 2^{(n-1)} * (n-1) * (n-2) * (n-3) * (n-4) * (n-5) * (n-6) * (x-7)^{(n-7)\)
Now let's evaluate these derivatives at x = 7:
\(f(7) = (-1)^n * n! * 2^n * (n-1)\\f'(7) = -(-1)^n * n! * 2^{(n-1)} * (n-1) * (n-2)\\f''(7) = (-1)^n * n! * 2^{(n-1)} * (n-1) * (n-2) * (n-3) * (n-4)\\f'''(7) = -(-1)^n * n! * 2^{(n-1)} * (n-1) * (n-2) * (n-3) * (n-4) * (n-5) * (n-6)\)
Now we can substitute these values into the Taylor series expansion formula:
\(f(x) = f(7) + f'(7)(x-7) + (f''(7)(x-7)^2)/2! + (f'''(7)(x-7)^3)/3! + ...\)
Simplifying further, we get:
\(f(x) = (-1)^n * n! * 2^n * (n-1) + (-1)^n * n! * 2^(n-1) * (n-1) * (n-2) * (x-7) + (-1)^n * n! * 2^(n-1) * (n-1) * (n-2) * (n-3) * (n-4) * (x-7)^2/2 + (-1)^n * n! * 2^{(n-1)} * (n-1) * (n-2) * (n-3) * (n-4) * (n-5) * (n-6) * (x-7)^3/6 + ...\)

Brandon is currently 6 81 years old.
Let M be Michael's age and B be Brandon's age.
We are given that Michael is 3 33 times as old as Brandon. This means that M = 3 33 × B
We are also given that 18 1818 years ago, Michael was 9 99 times as old as Brandon. This means that M - 18 1818 = 9 99 × (B - 18 1818).
We can combine these two equations to solve for Brandon's current age:
3 33 × B = (9 99 × B) + 18 1818
2 66 × B = 18 1818
B = 18 1818 / 2 66 = 6 81.

the sides of an equilateral triangle are increasing at a rate of 10cm/min. at what rate is the area of the triangle increasing when the sides are 30cm long?(3.9
The area of the triangle is increasing at a rate of 450sqrt(3) cm²/min.
What is the rate at which the area of an equilateral triangle is increasing?
To find the rate at which the area of the equilateral triangle is increasing, we first need to know the formula for the area an equilateral triangle, which is:
of
Area = (sqrt(3)/4) x (side)²
where side is the length of one of the sides of the equilateral triangle.
We are given that the sides of the equilateral triangle are increasing at a rate of 10cm/min. This means that at any given time t, the length of each side is given by:
side = 30 + 10t
We want to find the rate at which the area of the triangle is increasing when the sides are 30cm long. This means that we need to evaluate the derivative of the area formula with respect to time t when side = 30. Taking the derivative of the area formula, we get:
dA/dt = (sqrt(3)/2) x side x (d(side)/dt)
Substituting side = 30 + 10t and d(side)/dt = 10, we get:
dA/dt = (sqrt(3)/2) x (30 + 10t) x 10
When t = 0 (i.e. when the sides are 30cm long), we get:
dA/dt = (sqrt(3)/2) x (30) x 10 = 450sqrt(3)
Therefore, when the sides of the equilateral triangle are increasing at a rate of 10cm/min and are 30cm long, the area of the triangle is increasing at a rate of 450sqrt(3) cm²/min.

Z distribution.pdf For a typical driver who drives less than 10,000 miles per year, the probability of him/her having an accident in a year is _____________.
The probability of a typical driver who drives less than 10,000 miles per year having an accident in a year is 9.18%.
To calculate the probability of a driver who drives less than 10,000 miles per year having an accident, we can use the Z-score and the standard normal distribution.
First, we need to calculate the Z-score for a driver who drives less than 10,000 miles per year. The Z-score formula is:
Z = (X - μ) / σ
Where:
X is the value we want to calculate the Z-score for (10,000 miles per year),
μ is the mean (15,000 miles per year), and
σ is the standard deviation (3,750 miles per year).
Plugging in the values, we get:
Z = (10,000 - 15,000) / 3,750
Z = -1.333
Looking up the Z-score -1.333 in the standard normal distribution table, we find the probability to be approximately 0.0918 or 9.18%.
Therefore, the probability of a typical driver who drives less than 10,000 miles per year having an accident in a year is approximately 9.18%.

the measure of one interior angle of a rhombus is \(79^{\circ}\) . what are the measures of the other three interior angles?
Step-by-step explanation:
a rhombus is a parallelogram with 4 identical sides.
it has therefore two pairs of equal angles.
as any quadrilateral the sum of all interior angles is 360°.
(and yes, as add-on, the diagonals bisect each other at right angles).
so, one interior angle is 79°.
that means it has a twin that is also 79°.
together they have 79×2 = 158°.
that leaves
360 - 158 = 202°
for the other 2 angles (they must be equal too).
so, each of them has
202/2 = 101°
so, the other 3 angles are
79°, 101°, 101°

Answer:
I think it's either 1/2 or 1/3.
T/F: The proportion in the body of a normal distribution can never be less than 0.50.
This statement ''The proportion in the body of a normal distribution can never be less than 0.50.'' is false because the proportion in the body of a normal distribution can be less than 0.50, depending on the location of the mean and the spread of the distribution.
In fact, for a normal distribution with a mean of μ and standard deviation of σ, approximately 68% of the area under the curve falls within one standard deviation of the mean (i.e., between μ - σ and μ + σ), which means the proportion in the body of the distribution is about 0.68.
The remaining 32% is split evenly between the tails of the distribution, which means the proportion in each tail is about 0.16.
So, the proportion in the body of the distribution is greater than 0.50.
