The breadth of a rectangle is half of its length. If its perimeter is 76m,find its length and breadth.​

C. The probability of the type I error best defines the notion of the significance position of a thesis test.

The significance position, denoted by alpha( α), is the probability of rejecting the null thesis(H_o) when it's actually true. This is also known as a type I error, which occurs when we inaptly reject a true null thesis.

Option a isn't correct because the probability of rejecting H_o, whether it's true or not, isn't fixed and depends on the sample and the chosen significance position.

Option b isn't correct because it describes the p- value, which is a affiliated conception but not the significance position. The p- value is the probability of observing a sample statistic as extreme or more extreme than the one actually attained, assuming the null thesis is true.

Option d is also not correct because it describes the probability of a type II error, which occurs when we fail to reject a false null thesis. The probability of a type II error is denoted by beta( β) and is told by factors similar as sample size and effect size.

The integral of 1/(1-x^2) is arctan(x).

An integral is a mathematical operation that calculates the area under a curve by breaking it into infinitely small segments and summing them up.

To solve this integral, we use the substitution method with u=1-x^2:

∫1/(1-x2)dx =∫du/u (substitute u=1-x2)
= ln|u| + C (integrate with respect to u)
= ln|1-x2| + C (substitute back in the original expression)
= ln|1-x2| + C (substitute back in the original expression)
= arctan(x) + C (use the identity ln|1-x2| = arctan(x))

The point 3/4th of the way from point A to point B is (3.25, -1.25).

What is the coordinate geometry?

In geometry, a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements

To determine the point 3/4th of the way from point A to point B, we can use the midpoint formula to find the coordinates of the midpoint M of the line segment AB, and then use those coordinates to find the point 3/4th of the way from point A to point B.

The midpoint M of the line segment AB can be found using the midpoint formula:

M = ((x1 + x2)/2, (y1 + y2)/2)

where (x1, y1) and (x2, y2) are the coordinates of points A and B, respectively.

Substituting the given coordinates, we get:

M = ((3 + 4)/2, (2 - 3)/2) = (3.5, -0.5)

Now we can find the point 3/4th of the way from point A to point B by starting at point A and moving 3/4th of the way towards point B. To do this, we can use the following formula:

P = ((1 - 3/4)*x1 + (3/4)*x2, (1 - 3/4)*y1 + (3/4)*y2)

Substituting the coordinates of points A and B, we get:

P = ((1 - 3/4)*3 + (3/4)*4, (1 - 3/4)2 + (3/4)(-3)) = (3.25, -1.25)

Hence, the point 3/4th of the way from point A to point B is (3.25, -1.25).

While looking at the critical points of a function f(x) is a useful first step in finding its maxima and minima, it is not enough by itself to determine all of them.

The statement is partially correct. If a function f(x) is continuous on a closed interval, it is possible to find its absolute maxima and minima by looking at the points where f'(x) = 0, but this is not enough to guarantee that you have found all of them.

The reason why this is the case is because the condition f'(x) = 0 only identifies critical points, which are points where the function may have an extremum (either a maximum or a minimum). To determine whether a critical point is indeed a maximum or a minimum, you need to analyze the behavior of the function near the critical point.

One way to do this is by using the second derivative test, which states that if f(x) is twice differentiable and f''(x) > 0 at a critical point x, then f(x) has a local minimum at x. Similarly, if f''(x) < 0 at a critical point x, then f(x) has a local maximum at x.

You also need to use additional tools, such as the second derivative test, to verify whether the critical points are indeed extrema.

Given that;

Aaron has two children, Gabriel and Caroline. Gabriel is older than Caroline. The difference of their ages is 5. The sum of their ages is 33.

Let C represent Caroline's age and G represent Gabriel's age.

Hence, We can formulate;

The difference of their ages is 5.

⇒ G - C = 5  .. (i)

The sum of their ages is 33.

⇒ G + C = 33 .. (ii)

Add (i) and (ii);

⇒ 2G = 38

The amount of time in which the simple interest on Rs7560 be Rs1102.50 at 25/4% per annum, 5 years

Simple interest is an amount which is calculated for a certain period of time and for a certain rate, in simple interest calculation there are three factors which we consider: principal amount(P), rate(R) and time(T).

Every time we calculate simple interest the principal values will be the same unlike compound interest.

Formula;    Simple Interest(I) =  P × R × T/100

To find the time it takes for the simple interest on Rs. 7560 to be Rs. 1102.50 at 25/4% per annum, we can use the formula for simple interest:

We are given I = 1102.50 and P = 7560, and the interest rate is 25/4% per annum, which we can convert to a decimal:

r = 25/4% ÷ 100

 = 0.25/4

 = 0.0625

Now, we can substitute the known values into the formula and solve for t:

1102.50 = 7560 x r x t

1102.50 / 7560 = r x t

t = 1102.50 / (7560 x 0.0625)

t = 5 years

So, it will take 5 years for the simple interest on Rs. 7560 to be Rs. 1102.50 at 25/4% per annum.

The solution to the equation is x = 0 or x = 2πn, where n is an integer.

Starting with the given equation:

sec(x) + tan(x) = 1

We know that sec(x) is equal to 1/cos(x), so we can substitute that in:

1/cos(x) + sin(x)/cos(x) = 1

Combining the two fractions on the left side:

(1 + sin(x))/cos(x) = 1

Cross-multiplying to eliminate the fraction:

1 + sin(x) = cos(x)

Now, we can use the Pythagorean identity to substitute in for sin(x)^2:

1 + (1 - cos(x)^2) = cos(x)

Simplifying:

2 - cos(x)^2 = cos(x)

Rearranging:

cos(x)^2 + cos(x) - 2 = 0

This is a quadratic equation in terms of cos(x), so we can use the quadratic formula:

cos(x) = (-1 ± sqrt(1 + 8))/2

cos(x) = (-1 ± 3)/2

cos(x) = -2 or cos(x) = 1

Since cos(x) can't be negative, we can discard the -2 solution, leaving us with cos(x) = 1. This means that x must be 0 or a multiple of 2π. Checking our work, we can see that when x = 0:

sec(0) + tan(0) = 1 + 0 = 1

So x = 0 is indeed a valid solution.

Therefore, the solution to the equation is x = 0 or x = 2πn, where n is an integer.
