The formula to calculate the population attributable fraction (PAF) for weekend admissions is as follows:

Population Attributable Fraction

(PAF) = (Pe * [RR - 1]) / [Pe * (RR - 1) + 1]

Where Pe = Proportion of patients exposed (weekend admissions)

RR = Relative risk of the exposed group (mortality rate of weekend admissions/mortality rate of weekday admissions)

PAF for weekend admissions

PAF = (23297/93621) * [(5929/2467) - 1] / [(23297/93621) * [(5929/2467) - 1] + 1]

= 0.1455 or 14.55%

The PAF for weekend admissions is 14.55%.

This means that 14.55% of in-hospital mortality among people admitted for a stroke could be attributed to weekend admissions.

What further information is required to assess the validity of the conclusions?

It's critical to know if there are any other variables that might influence the association between weekend admissions and in-hospital mortality.

If so, then the current estimates might be biased.

Furthermore, because this is an observational study, it cannot establish causality.

As a result, any conclusions made must be interpreted with caution.

If Mrs hall is making a circular hard for our outdoor green space the garden has a diameter of 11m then Mrs. Hall spent $198.37 on the plastic fencing.

The circumference of a circle can be calculated as C = πd, where d is the diameter and π is approximately 3.14.

The diameter of the garden is 11m, so the circumference is:

C = πd

= 3.14 × 11m

= 34.54m

Mrs. Hall needs to buy enough plastic fencing to go around the edge of the circular garden, which has a length equal to the circumference of the circle.

The cost of the fencing is $5.75 per meter, so the total cost will be:

Total cost = cost per meter × length of fencing

= $5.75/m × 34.54m

= $198.37

Therefore, Mrs. Hall spent $198.37 on the plastic fencing.

The Euclidean algorithm applied to inputs a and b halts in at most 2 log2(b) + 2 steps. This is proven by analyzing the efficiency of the algorithm and the relationship between the input values.

To prove this, let's start with the fact that the Euclidean algorithm uses the Division Algorithm, which means it computes the remainder between two numbers (a % b). When we apply this operation repeatedly, the remainders get smaller until we reach 0 or 1, at which point we have found the greatest common divisor (gcd).

Let's consider a sequence of remainders, r1, r2, ..., rn, where r1 = a % b, r2 = b % r1, and so on. Notice that each remainder is strictly smaller than the previous one. Since the sequence of remainders is decreasing, there must be a point where it stops, i.e., it halts.

Now, let's analyze the steps. Each time we apply the algorithm, we cut the input size by at least half. The worst-case scenario occurs when the input values are consecutive Fibonacci numbers, where the algorithm takes roughly log2(b) steps to halve the input size. Since this halving process can happen twice, we get a total of 2 log2(b) steps.

Finally, we add 2 to account for the two initial steps (gcd(a, 1) and gcd(a, 0), which take 0 steps). Therefore, the Euclidean algorithm halts in at most 2 log2(b) + 2 steps.

To express the internal shear in a beam as a function of x for the interval 0 ≤ x ≤ l/3, we need to know the specific beam configuration, loading conditions, and any relevant equations or formulas associated with shear in beams.

The internal shear in a beam refers to the force that acts parallel to the cross-section of the beam and can vary along the length of the beam. The expression for the internal shear as a function of x depends on the specific beam configuration and loading conditions.

To determine the internal shear in the beam as a function of x, one needs to consider the beam's support conditions, applied loads, and any distributed or concentrated forces. The shear force can be determined by analyzing the equilibrium of forces acting on a section of the beam.

The calculation of internal shear typically involves using the principles of static equilibrium, such as applying the equations of equilibrium (sum of forces and moments equal to zero). Additionally, the bending moment diagram or shear force diagram may be required to determine the shear force as a function of x.

The probability that we have picked exactly n cards by multiplying the probability of picking each card, which is \($\frac{13}{52}\)

Verified that, after taking summation over n = 1, 2, . . ., the sum of the probabilities above equals to 1.

(1) The probability of picking exactly n cards to cover all 4 shades can be calculated as follows:

For n = 1, the probability of picking exactly 1 card is 0, as it is not possible to pick only one card and cover all 4 shades.

For n = 2, the probability of picking exactly 2 cards is:

\($=(\frac{13}{52})\times (\frac{12}{52} )\\\\= \frac{13\times12}{52\times 52}\)

For n = 3, the probability of picking exactly 3 cards is:

\($=(\frac{13}{52})\times (\frac{12}{52} )\times(\frac{11}{52}) \\\\= \frac{13\times12\times11}{52\times 52\times52}\)

And so on, we can calculate the probability of picking exactly n cards by multiplying the probability of picking each card, which is \($\frac{13}{52}\).

(2) To verify that the sum of the probabilities is equal to 1 , we can add up the probabilities for all values of n from 1 to 52 :

\($& \mathrm{P}=\left(\frac{13}{52}\right) \times\left(\frac{12}{52}\right)+\left(\frac{13}{52}\right) \times\left(\frac{12}{52}\right) \times\left(\frac{11}{52}\right)+\ldots+\left(\frac{13}{52}\right) \times\left(\frac{12}{52}\right) \times \ldots \times \frac{52-(\mathrm{n}-1)}{52} \\\)

According to the question and after using the Pythagorean theorem the length of one side of the roof is 7.416 metres.

The Pythagorean Theorem is a mathematical formula used to determine the length of the sides of a right triangle. It is named after the Greek mathematician Pythagoras, who is credited with discovering the formula in the 6th century BC. The theorem states that the sum of the squares of the two shorter sides of the triangle is equal to the square of the hypotenuse (the longest side of the triangle). In equation form, it is expressed as a² + b² = c², where a and b are the lengths of the two shorter sides of the triangle and c is the length of the hypotenuse.

We know that the hypotenuse is 8 metres (the width of the shed) and the two shorter sides are 3 metres (the height of the walls) and y (the length of the side of the roof).
Therefore, using the Pythagorean theorem, we have:
3² + y² = 8²
9 + y² = 64
y² = 55
y = √55
y = 7.416 metres
Therefore, the length of one side of the roof is 7.416 metres.

The computer equipment was acquired at a cost of $73,700 with an estimated residual value of $34,600 and a useful life of 5 years. The depreciable cost of the equipment is $39,100. The straight-line rate is 20%, and therefore, the annual straight-line depreciation for the computer equipment is $7,820.

a. To determine the depreciable cost, we subtract the estimated residual value from the initial cost: $73,700 - $34,600 = $39,100.

b. The straight-line rate is calculated by dividing 100% by the estimated useful life of the equipment. In this case, the straight-line rate is 100% / 5 = 20% per year.

c. The annual straight-line depreciation is found by multiplying the depreciable cost by the straight-line rate. Thus, the annual depreciation is $39,100 * 20% = $7,820 per year.

By following these calculations, we can determine that the depreciable cost of the computer equipment is $39,100, the straight-line rate is 20%, and the annual straight-line depreciation amounts to $7,820.
