In a recent year, 27.6% of all registered doctors were female. If there were 59,100 female registered doctors that year, what was the total number of registered doctors?

The frequency of a class is the number of data points that fall within the class is 1.

To determine the frequency of each class in the table shown, we must first divide the data points into the respective classes. The classes are 1003, 1062, 1063, 1122, 1123, 1182, 1183, 1242, 1243, 1302, 1303, and 1362.

For the class 1003, the frequency is 1, since there is only one data point (1003) in this class.

For the class 1062, the frequency is also 1 since there is only one data point (1062) in this class.

For the class 1063, the frequency is also 1 since there is only one data point (1063) in this class.

For the class 1122, the frequency is 1 since there is only one data point (1122) in this class.

For the class 1123, the frequency is 1 since there is only one data point (1123) in this class.

For the class 1182, the frequency is 1 since there is only one data point (1182) in this class.

For the class 1183, the frequency is 1 since there is only one data point (1183) in this class.

For the class 1242, the frequency is 1 since there is only one data point (1242) in this class.

For the class 1243, the frequency is 1 since there is only one data point (1243) in this class.

For the class 1302, the frequency is 1 since there is only one data point (1302) in this class.

For the class 1303, the frequency is 1 since there is only one data point (1303) in this class.

For the class 1362, the frequency is 1 since there is only one data point (1362) in this class.

Therefore, the frequency of each class in the table shown is 1.

The standard deviation of a point estimator is a measure of the variability or precision of the estimator.

In statistics, a point estimator is a function that uses sample data to estimate an unknown parameter of a population. The standard deviation of a point estimator quantifies how much the estimates from different samples are expected to deviate from the true value of the parameter. A smaller standard deviation indicates a more precise estimator, as the estimates are expected to be closer to the true value. Conversely, a larger standard deviation suggests a less precise estimator with estimates that are more spread out. By calculating the standard deviation of a point estimator, we can assess its reliability and determine the level of confidence we can have in the estimated parameter value.

There are 126 ways to select ten comics if we choose at least one of each book.

Here we have a total of 6 different comics.

Now we have selected 10 comics such that we have at least one comic each.

Let's select one copy of each copy. This can be done in 1 way. Thus we are left with 4 comics to select from 6 different comics.

This is a  repetition and unordered form of selection since each comic can have n number of copies.

The question is incomplete and the complete question is shown in the attached picture.

The temperature (rounded to two decimal places) of the air as it exits the duct is equal to (a) 20.96 °C.

To solve this problem, we can apply conservation of mass and conservation of energy equations to the air flowing through the duct.

First, we can use the continuity equation to relate the velocity of the air to its volumetric flow rate:

A1v1 = A2v2

where A is the cross-sectional area of the duct, v is the velocity of the air, and subscripts 1 and 2 refer to the inlet and outlet conditions, respectively. Solving for v1, we get:

v1 = (A2/A1) * v2

where A1 = π(0.26/2)^2 = 0.0534 m^2 is the cross-sectional area at the inlet and A2 = π(0.26/2)^2 = 0.0534 m^2 is the cross-sectional area at the outlet. Substituting the given values, we get:

v1 = (0.0534/0.0534) * (17/60) / (π(0.13)^2/4) = 6.15 m/s

So the answer to the first question is (a) 6.15 m/s.

Next, we can apply the conservation of energy equation to find the final temperature of the air. Assuming that the process is adiabatic (no heat transfer to the surroundings), the conservation of energy equation can be written as:

h1 + (v1^2)/2 + gz1 = h2 + (v2^2)/2 + gz2

where h is the specific enthalpy of the air, v is the velocity of the air, g is the acceleration due to gravity, z is the elevation, and subscripts 1 and 2 refer to the inlet and outlet conditions, respectively. Assuming that the elevation is constant (z1 = z2) and neglecting the change in specific enthalpy (h1 = h2), we can simplify the equation to:

(v1^2)/2 = (v2^2)/2 + Q/m

where Q is the heat transferred to the air by the air-conditioner and m is the mass flow rate of the air. Solving for the final temperature, we get:

T2 = T1 + (2Q)/(mCp)

where Cp is the specific heat capacity of air at constant pressure. Substituting the given values, we get:

T2 = 12 + (2 * 3) / (17/60 * 1.005) = 20.96 °C

So the answer to the second question is (a) 20.96 °C.

Answer:

y = - 21

Step-by-step explanation:

System of equations:

- 3x - 2y = 54

To find y will look to eliminate x:

- 6x + 2y = - 18

- 3x - 2y = 54   (multiply both sides by -2)

- 6x + 2y = - 18

 6x + 4y = - 108

Answer:

P = 35.98 cm

Step-by-step explanation:

The Perimeter of a shape is the distance around the outside of it. This semi-circle (half circle) has a straight part and the curved part. See image. The straight part is the diameter (distance through the center) it is double the radius that was given, 7 cm.

The circumference of a circle is the perimeter of the whole circle.

C = 2pi•r or pi•d

C = 2pi•7 = 14pi

But you only need half, so 14pi/2 is 7pi.

ADD the straight part and the curved part to get the whole distance around the shape

P = 14 + 7pi

P ~= 35.98 cm

Answer:

10*0.11515

Step-by-step explanation:

The exact value of cscθ is (35 * √(1190)) / 1190.

To find the value of cscθ (cosecant θ) given that cosθ = 1/√35 and sinθ < 0, we can use the reciprocal relationship between sine and cosecant.

Recall that cscθ is the reciprocal of sinθ. Since sinθ is negative, we can determine its value based on the quadrant in which θ lies.

In the unit circle, the cosine is positive in the first and fourth quadrants, while the sine is negative in the third and fourth quadrants.

Given that cosθ = 1/√35 and sinθ < 0, we can conclude that θ lies in the fourth quadrant.

Using the Pythagorean identity, sinθ = √(1 - cos^2θ), we can calculate the value of sinθ:

sinθ = √(1 - (1/√35)^2)

     = √(1 - 1/35)

     = √(34/35)

     = √34 / √35

     = (√34 / √35) * (√35 / √35)     [Multiplying numerator and denominator by √35 to rationalize the denominator]

     = √(34 * 35) / 35

     = √(1190) / 35

Now, since cscθ is the reciprocal of sinθ, we have:

cscθ = 1 / sinθ

     = 1 / (√(1190) / 35)

     = 35 / √(1190)

     = (35 * √(1190)) / 1190.

The standard deviation, S.d = 4.45 (using calculator)

The test statistic, T : \(d`\) / (S.d/√n)

T = 2.44 / (4.45/√18)

T = 2.44 / 1.0488750

Step-by-step explanation:

Area of triangle + area of square + area of triangle = total area

(Area of a triangle: A = 1/2bh)

(Area of a square: A = bh)

Area of smallest triangle =

A = 1/2 (2) (2) = 2

Area of largest triangle=

Area of the square =

A = 2 x 2 = 4

The mean temperature is approximately 30.64, the median temperature is approximately 29.5, the highest range of temperature is 37-39, the lowest range of temperature is 25-27, and the modal class is 28-30 with 36 cities.

How to calculate the highest and lowest range of temperature?

To calculate the mean temperature, we need to find the sum of all the temperatures and divide it by the total number of cities:

Mean = (25*25 + 29*36 + 32*30 + 35*22 + 38*15) / (25 + 36 + 30 + 22 + 15)

    = 30.64

Therefore, the mean temperature is approximately 30.64.

To calculate the median temperature, we need to find the middle temperature value. First, we need to arrange the temperatures in ascending order:

25-27, 25-27, 25-27, ..., 25-27 (25 times)

28-30, 28-30, ..., 28-30 (36 times)

31-33, 31-33, ..., 31-33 (30 times)

34-36, 34-36, ..., 34-36 (22 times)

37-39, 37-39, ..., 37-39 (15 times)

The total number of cities is 128. Since 128 is an even number, the median is the average of the two middle values:

Median = (28-30 + 31-33) / 2

      = 29.5

Therefore, the median temperature is approximately 29.5.

The highest range of temperature is 37-39, and the lowest range of temperature is 25-27.

The modal class is the temperature range with the highest frequency, which is 28-30 (36 cities).
