Publishing scientific papers online is fast, and the papers can be long. Publishing in a paper journal means that the paper will forever in libraries. The British Medical Journal combines the two: it prints short and readable versions, with longer versions available online. The journal asked a random sample of 104 of its recent authors several questions. One question was "Should the journal continue using this system?" In the sample, 72 said "yes." Do the data give good evidence that more than 67% of authors support continuing this system? Interpret the p-value in the context of the problem. If an error has been committed, explain which type of error could it be.
There is no significant evidence that more than two-thirds (67%) of authors support continuing this system.
Define null hypothesis?This hypothesis is either rejected or accepted, depending on whether the population or sample under investigation is viable.
In other words, the null hypothesis is an assertion that the sample observations are the result of chance. It is asserted that surveyors who are interested in the data have made this allegation. It has the prefix H0.
Let p be the proportion of authors who support continuing the system.
Then hypotheses are:
H0: p=0.67
Ha: p>0.67
For calculating the test statistic:
z = p(s)-p/√ [p0(1-p)/N]
where, p(s) = 72/104 ≈ 0.692, p is 0.67 and N is the sample size =104
Then Z ≈ 0.477
The test statistic's p-value is 0.317.
Since 0.317>0.05 and we're assuming a significance level of 0.05, we are unable to reject the null hypothesis.
p-value 0.317 is the likelihood that the sample is chosen from the distribution assumed under null hypothesis, that is where the fraction of authors favouring the new publication scheme is at most 0.67.

What is Investment ?
Investment refers to the purchase of goods that are not consumed today but are used in the future to create wealth. In financial terms, investment typically involves buying assets such as stocks, bonds, real estate or other financial instruments with the expectation of earning a profit or income from them.
Khomo paid R245,000 for the house, so his investment ratio is:
245,000 / 575,000 = 0.426
Peter's investment ratio is:
1 - 0.426 = 0.574
If they share the profit in the same ratio as their respective investment, then Peter will receive:
0.574 x 234,500 = 134,417.5
Therefore, Peter will receive R134,417.50 of the profit.

The surface area of a cube with a volume of 4913 cubic yards is 972 square yards.
What is surface area?Surface area is the measurement of the total area of a 3D object. It is the sum of all the individual faces of a 3D object, including the area of each side of the object. It is a way to measure the total exposed area of an object, including any protrusions or indentations.
The surface area of a cube is the sum of the areas of the six faces of the cube. The formula for the surface area of a cube is 6 × s2, where s is the length of the side of the cube.
In this case, the volume of the cube is 4913 cubic yards, so the length of the side of the cube is ∛4913 = 17. Therefore, the surface area of the cube is 6 × 172 = 972 square yards.
To find the surface area of a cube, the first step is to determine the length of the side of the cube. This is done by finding the cube root of the volume (in this case, 4913). Once the length of the side is known, the surface area of the cube is simply 6 times the length of the side squared.
In conclusion, the surface area of a cube with a volume of 4913 cubic yards is 972 square yards.

A system of equations can be used to determine whether the paths of the boats cross include the following:
A. y = -1/9(x - 1)² + 10.
y = 1/8x² - 7
How to determine the required system of equations?Based on the information provided about the first boat, the x-coordinate of the vertex can be determined as follows;
x = -b/2a
1 = -b/2a
b = -2a
Additionally, the standard form of the equation of a parabola (quadratic function) is given by;
y = a(x - h)² + k.
y = ax² - 2ax + c.
Therefore, the y-coordinate of the vertex is given by:
y = ax² - 2ax + c
10 = a(1)² - 2a(1) + c
c - a = 10 .......equation 1.
Since the parabola passes through the point (-8, 1), we have:
y = ax² - 2ax + c
1 = a(-8)² - 2a(-8) + c
80a + c = 1 .......equation 1.
Solving equations 1 and 2 simultaneously, we have:
81a = -9
a = -9/81 = -1/9
b = -2a = -2(-1/9) = 2/9
c = 10 + a = 10 - 1/9 = 89/9
Rewriting the equation for the first boat, we have:
y = -1/9x² + 2/9x + 89/9
y = -1/9(x - 1)² + 10.
For the second boat, the x-coordinate of the vertex can be determined as follows:
y = ax² + bx + c
x = -b/2a
0 = -b/2a
b = 0
Additionally, the y-coordinate of the vertex is given by:
y = ax² + c
-7 = a(0)² + c
c = -7
Since the parabola passes through the point (-8, 1), we have:
y = ax² + c
1 = a(-8)² - 7
a = -1/8
b = 0
c = -7
Rewriting the equation for the second boat, we have:
y = ax² + c
y = 1/8x² - 7

The Water Department checks the city water supply on a regular basis for
contaminants such as trihalomethanes (THMs). The Water Department takes
200 samples and estimates that the concentration of THMs in your drinking
water is 3 ppb (parts per billion), with a standard deviation of 0. 3 ppb.
Assuming the samples were random and unbiased, how much confidence
can you have in this data?
We can be 95% confident that the true mean concentration of THMs in your drinking water lies within the range [2.9584 ppb, 3.0416 ppb]. This was calculated using a confidence interval formula for the mean.
The confidence interval for the mean concentration of THMs can be calculated using the formula x ± z * (s/√n), where x is the sample mean, z is the z-score for a given confidence level, s is the sample standard deviation and n is the sample size.
In this case, we have x = 3 ppb, s = 0.3 ppb, and n = 200. To calculate the confidence interval at a certain confidence level (e.g. 95%), we need to find the corresponding z-score. For a 95% confidence level, the z-score is approximately 1.96.
Substituting these values into the formula above gives us:
3 ± 1.96 * (0.3/√200) = [2.9584, 3.0416]
So we can be 95% confident that the true mean concentration of THMs in your drinking water lies within the range [2.9584 ppb, 3.0416 ppb].

A rectangular portrait is 1 yard wide and 2 yards high. It costs $10.17 per yard to put a gold frame around the portrait. How much will the frame cost?
Answer:
The perimeter of the portrait is $2\times(1+2)=6$ yards.
To find the cost of the frame, we need to calculate the length of the frame needed, which is the same as the perimeter of the portrait. So, the length of the frame needed is 6 yards.
The cost of the frame will be the cost per yard multiplied by the length of the frame:
$6~\text{yards} \times $10.17/\text{yard} = $61.02$
Therefore, the frame will cost $61.02.

Jim takes out a mortgage for 30 years at an interest rate of 2. 49% and his monthly repayments are $986. 50. What is the principal loan amount? Round your answer to the nearest ten thousand dollars. Do NOT round until you have calculated the final answer
The principal mortgage amount is $220,000.
To compute the principal loan amount, we need to apply the compound interest formulation for a loan:
M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1]
Where M is the monthly reimbursement, P is the primary mortgage amount, i is the month-to-month interest charge, and n is the range of months.
First, we need to calculate the month-to-month interest charge:
i = 2.49% / 12 = 0.02075
Subsequent, we want to calculate the range of months:
n = 30 years x 12 months/year = 360 months
Now we are able to plug in the given values:
$986.50 = P [ 0.02075(1 + 0.02075)^360 ] / [ (1 + 0.02075)^360 – 1]
Solving for P, we get:
P = $221,114.07
Rounding to the nearest ten thousand dollars, the principal mortgage amount is $220,000.

let f(x)=6x-2 and g(x)=5x-kx+15. if k=3, what is the value of f(g(10))?
Answer:
We need to find the value of f(g(10)) when k = 3, where f(x) = 6x - 2 and g(x) = 5x - kx + 15.
First, we need to evaluate g(10) when k = 3:
g(x) = 5x - kx + 15
g(10) = 5(10) - 3(10) + 15
g(10) = 50 - 30 + 15
g(10) = 35
Now that we know g(10) = 35, we can evaluate f(g(10)):
f(x) = 6x - 2
f(g(10)) = 6(35) - 2
f(g(10)) = 208
Therefore, when k = 3, f(g(10)) = 208.

18x - 2 = 34
We add 2 to both sides:
18x - 2 + 2 = 34 + 2
Simplifying:
18x = 36
Finally, we divide both sides by 18:
18x / 18 = 36 / 18
Simplifying:
x = 2

Rewrite x/√16+x^2 by using x= 4 tan θ The answer should not include a radical.
The equation x/√16+x² can be rewritten by using x= 4 tan θ as x/4.
The given expression is x/√16+x^2 and we need to rewrite it by using x= 4 tan θ.
We know that 1 + tan2θ = sec2θ ⇒ 1 = sec2θ − tan2θ ... (1)
x = 4tanθ⇒ x/4 = tanθ ... (2)
Let's substitute (2) in (1) and get:
sec2θ − tan2θ = sec2θ − x²/16 ... (3)
Now, let's simplify the denominator and numerator of x/√16+x² using trigonometry.
We have:
x/√16+x²= x/[4sec2θ]
Using (2), we know that x = 4 tanθ, so substituting this in (3) we get:
sec2θ − x²/16 = sec2θ − (4tanθ)2/16= sec2θ − tan2θ= 1 (from equation (1))
Therefore,
x/√16+x²= x/[4sec2θ] = x/[4√(sec2θ − tan2θ)] (from equation (3))= x/[4√1]= x/4
Hence, x= 4 tan as x/4 can be used to rewrite x/16+x².

the area of base of a cylindrical tank is 38.5m². Find the perimeter of base
Answer: We know that the area of the base of a cylinder is given by the formula:
A = πr²
where A is the area of the base, π is the mathematical constant pi (approximately equal to 3.14), and r is the radius of the base.
To find the perimeter of the base, we need to know the circumference of the circle that forms the base of the cylinder. The formula for the circumference is:
C = 2πr
where C is the circumference and r is the radius.
To find the radius of the base, we can rearrange the formula for the area:
A = πr²
r² = A/π
r = √(A/π)
Substituting the given value for the area of the base, we get:
r = √(38.5/π) ≈ 3.5 m
Now, we can use the formula for the circumference to find the perimeter of the base:
C = 2πr = 2π(3.5) ≈ 22 m
Therefore, the perimeter of the base is approximately 22 meters.

Happy to help :)
The solution is, the value of the angle ADF = 35° .
Here, we have,
from the given diagram, we get,
ABCD is a trapezium.
EBC is a straight line.
F is the point on AB so that DFE is a straight line.
Angle BEF = 45°
Angle FBC = 100°
now, we have,
angle FBE = 180 - 100
= 80 degrees
now, from triangle BEF , we get,
Angle EFB = 55 degrees
again, as AFB is vertically opposite angle,
so, angle AFB = Angle EFB = 55 degrees
finally from triangle ADF , we get,
Angle ADF = 180 - 90 - 55
= 90 - 55
= 35 degrees
so, the value of the angle ADF = 35° .
