The Total number of registered doctors will be 246753.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

Let the total number of doctors be x.

Since 23.1% of all registered doctors were female. If there were 55,700 female registered doctors that year. This will be:

23.1% × x = 55700

0.231x = 55700

Divide

x = 57000 / 0.231

x =246753

The doctors are =246753.

The sum of integers is: S = n(a + l)/2

Integer numbers are those without fractional or decimal parts. When there are fewer numbers to add, it is possible to determine the sum of integers using basic mathematics. However, we employ the sum of integers formula if we need to add multiple consecutive integers at once. Our computations are made easier, and the amount of time we spend adding is reduced.

The sum of an arithmetic sequence's n terms is what is meant by the sum of integers formula. The formula for the sum of integers is:

S = n(a + l)/2

where,

S = sum of the consecutive integers

n= number of integers

a= first term

Answer:

x = -4u/3

Step-by-step explanation:

The first step is to create a fraction on both sides in order to prepare for cross-multiplication.

Cross-multiplication is a shortcut for the following technique, shown by this example.

a/b=c/d

Multiplying both sides of the equation by bd using the multiplication property of equality will then grant the equation ad = bc, and then a single component can be isolated by creating the equation a = bc/d for example using the division property of equality.

Back to cross-multiplication, however, creating a fraction of both sides can be achieved by creating the equation u/1 = -3x/4, since any number divided by 1 is equal to itself.

Then, by cross-multiplying u and 4 and 1 and -3x, you get the equation 4u = -3x.

Dividing both sides by -3 will then grant the final answer of x = -4u/3.

Answer:

m = 9

Step-by-step explanation:

The three angles shown all add up together to 180° . The angle in the middle is marked with a little square that means it is 90°. So we can write an equation:

4m-6+90+6m+6=180°

combine like terms.

10m + 90° = 180°

subtract 90

10m = 90

After 20 years, the wetland will have decreased in area by 20/5 = 4 times.

If the area has decreased by a sixth every 5 years, it will decrease by 4/6 = 2/3 after 20 years.

Therefore, the percent of the total area that disappears after 20 years is 2/3 = 66.67%.

Rounding to two decimal places, the answer is 66.67%.

Area of triangle PQR = 48 cm², thus angle QPR ​= 43.31°

The amount of space occupied by a flat (2-D) surface or an object's form is known as its area. A planar figure's area is the area that its perimeter encloses. The quantity of unit squares that completely encircle the surface of a closed figure is its area. Square measurements for area include cm² and m².

A shape's perimeter is the space surrounding it. The interior volume of a form is measured by area.

As we know,

area of a triangle = 1/2 × a × b × sinθ

here, area = 48 cm²

side lengths of two triangle are:

a = 10

b = 14

now, putting the value:

area of a triangle = 1/2 × a × b × sinθ

48 = 1/2× 10 × 14 × sinθ

or, 90 = 140 × sinθ

or, sinθ = 90/140

or, sinθ = 0.686

or, θ = sin⁻¹(0.686)

or, θ = 43.31°

So, angle QPR ​= 43.31°

The Correct option Will be  An event is unusual if it has a low probability of occurring The choice of a cutoff should consider the context of the problem i.e. A.

The likelihood of an event is expressed by probability. The occurrence of a random event is the subject of this mathematical field of study. The value is between zero and one. In mathematics, probability is a tool for calculating the likelihood that certain events will take place.

Probability is the possibility of something happening. The probability distribution also makes use of this central concept in probability theory. We must first ascertain the total number of possibilities before calculating the likelihood that a specific event will occur.

When something unusual happens, it does not happen frequently in terms of sight or sound.

The probability that an event will occur P(E) = the number of positive outcomes divided by the total number of outcomes.

Now,

As an unusual event has low probability because it does not happen often and The same cutoff should not be used to detect unexpected events all of the time. Choosing a cutoff is subjective, and it should consider the repercussions of erroneously labelling an occurrence as rare.

Hence,

To determine if the die is fair or not, we can perform a chi-square goodness-of-fit test. The null hypothesis for this test is that the observed frequencies match the expected frequencies, assuming the die is fair.

We can set the expected frequency for each face to be 50/6 = 8.33 (since there are six faces on the die and 50 total throws).

Next, we calculate the chi-square test statistic by comparing the observed frequencies to the expected frequencies. Using the formula:

χ² = ∑((O - E)² / E), where O is the observed frequency and E is the expected frequency.

Once we have the test statistic, we compare it to the critical value from the chi-square distribution with (number of categories - 1) degrees of freedom (in this case, 6 - 1 = 5) at a chosen significance level (e.g., 0.05). If the test statistic exceeds the critical value, we reject the null hypothesis and conclude that the die is not fair.

It's not possible to perform the chi-square test without the observed frequencies for each face of the die. Please provide the observed frequencies for each face, and I can help you analyze the data to determine if the die is fair or not.

The given function → f(x) = x⁵ - 3x³ is odd in nature.

A function f(x) is even if f(−x) = f(x) and is odd if f(−x) = − f(x).

Given is the function -

f(x) = x⁵ - 3x³

In order to find f(-x), replace 'x' by '-x' in f(x) -

f(x) = x⁵ - 3x³

f(-x) = (-x)⁵ - 3(-x)³

f(-x) =  - x⁵ + 3x³

f(-x) =  3x³ -  x⁵

Now -

f(-x) ≠ f(x)

So, it is not a even function.

In order to find '-f(x)', multiply f(x) by '-1' -

f(x) = x⁵ - 3x³

- f(x) = - (x⁵ - 3x³) = - x⁵ + 3x³ = 3x³ - x⁵

Now -

f(-x) = -f(x)

So, it is a odd function.

The ways are the \(C_{20} ^{90}\) which are we  there to select the applicants who will be hired with the help of combination.

According to the statement

we have to find that the number of ways are there to select the applicants who will be hired.

So, For this purpose, we know that the

A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.

Here we use the combination.

And from the given information:

20 applicants from a pool of 90 applications will be hired.

And according to this the combination becomes:

\(C_{20} ^{90}\)

then solve it

\(C_{20} ^{90} = \frac{90!}{20! (70!)}\)

\(C_{20} ^{90} = \frac{90*89*88*87*86*85*84*83*82!}{20*19*18*17*16*15*14!}\)

Then after solve it

\(C_{20} ^{90} = \frac{89*11*87*43*14*83*82!}{19*14!}\)

Now open another factorial

\(C_{20} ^{90} = \frac{89*11*87*43*14*83*82*81*80*79*78*77*76*75*74*73*72*71}{19*14*13*12*11*10*9*8*7*6*5*4*3*2*1}\)

Now solve this then

\(C_{20} ^{90} = {89*11*87*43*83*82*79*15*74*73*71}\).

Answer:

The original number is 83

Step-by-step explanation:

let the number be ab

Sum of the two is 11

a + b = 11

tens digit a is one less than 3 times the ones digit

3b - a = 1

a = 3b - 1

3b -1 + b = 11

4b = 11 + 1

4b = 12

b = 12/4

b = 3

a = 3b - 1

a = 3(3) - 1

a = 9-1

a) The speed of the car in front of you appears to be coming towards you is 41t₀. The speed of the car behind you appears to be gaining on you at the same speed is 41t₀. Someone standing on the ground would say that the two cars are moving at t₀ + 41t₀ = 82t₀.

b) We know that the speed of the fish in still water is V, and the speed of the current is C. And the time the fish takes to swim downstream is 61t₀ and upstream is 31t₀. So:

Downstream: V + C = L / (61t₀)

Upstream: V - C = L / (31t₀)

Adding the two equations we get:

2V = (4L / 61t₀) → V = (2L / 61t₀)

Therefore, C = (L / 61t₀) which is the speed of the current.

c)In order to get across the river, you have to swim at a speed perpendicular to the current (so that you don't get drifted away) and with a speed of fa * 3L, as given. Therefore, the required angle can be found by:

f a3L = (V cos α)sin α

= (C cos α)sin αtan α

= (fa * 3L) / C

= 3fa * 61t₀ / Ld)

The width of the river is 31L. The time taken to get across can be found using the formula:

Time = (Distance) / (Speed)

Since the speed of the current is C, the effective speed (in still water) is fa * 3L, the distance to be crossed is 31L, and the time taken is:

Time = (31L) / (fa * 3L - C)  

= (31L) / (3fa * 61t₀ / L)

= (31L²) / (3fa * 61t₀)
