The British Doctors Study is an important study, which has followed participants for 60 years to investigate the relationship between tobacco smoking and cause specife mortality among British doctors. In 1951, a questionnaire on smoking habits was sent to 49,913 male and 10,323 female doctors registered with the British General Medical Council 34.440 male doctors and 6194 female doctors gave sufficient information to classify their smoking status (Doll and Pato, 1976: Doll et al, 1980). The vital status of these doctors was followed up from the records of the Registrar General's Office, the British Medical Council, and the British Medical Association. The causes of death for 10,072 male and 1094 female doctors who had died during the first 20 and 22 years of follow-up respectively were ascertained from death certificates. The rate of death from lung cancer among wokers was compared with that among non-smokers 1. What is the study type and design? 2. What is the best statistical measure ?

The coordinates of the point at 3/4 of the distance from A to B from A is (-3.5, 1.25)

The coordinates of point A = (-5, -4),

The coordinates of the point B = (-3, 3)

Let the point at the distance 3/4 from A to B = P

The coordinates of point 3/4 from A to B = P

At the x-coordinate, the distance from B to A is =  -3-(-5) = 2 units.

At the y-coordinate, the distance from B to A is = 3-(-4) = 7 units.

Hence, the coordinates of P = (-5 + (3/4×(x-coordinate), -4 + 3/4×(y-coordinate)

                                            P = (-5 + (3/4×(2), -4 + 3/4×(7))

                                            P = (-3.5, 1.25)

Hence, the coordinates of the point at 3/4 of the distance from A to B from A is (-3.5, 1.25).

Answer:

If bill is 28 years older than him, but also 3 times older than him, then you divide 28 by 3, which gives you 9.3. So that means kevin is around 9 1/4 years old and bill is around 37 and 1/4 years old, but you dont ahve to count the fraction if you dont want to, all that matters is the whole number.

Step-by-step explanation:

Bill is 42, while Kevin is 14 years old

Represent Bill's age with B, and Kevin's age with K.

So, we have the following equations

B = 3K and B = 28 + K

Substitute 3K for B in the second equation

\(3K = 28 + K\)

Collect like terms

\(-K + 3K = 28\)

\(2K = 28\)

Divide both sides by 2

\(K = 14\)

Substitute 14 for K in the first equation

\(B =3 \times 14\)

\(B =42\)

Hence, Bill is 42, while Kevin is 14 years old

P(A|B) = 0.60, which means that given event B has occurred, the probability of event A occurring is 0.60.  P(A∪B) = 0.70, which represents the probability of event A or event B or both occurring.

a. The probability of A given B, denoted as P(A|B), can be calculated using the formula:

P(A|B) = P(A∩B) / P(B)

Given that P(A∩B) = 0.15 and P(B) = 0.25, we can substitute these values into the formula:

P(A|B) = 0.15 / 0.25

The result is P(A|B) = 0.60.

b. The probability of A union B, denoted as P(A∪B), can be calculated using the formula:

P(A∪B) = P(A) + P(B) - P(A∩B)

Given that P(A) = 0.60, P(B) = 0.25, and P(A∩B) = 0.15, we can substitute these values into the formula:

P(A∪B) = 0.60 + 0.25 - 0.15

The result is P(A∪B) = 0.70.

The answer is 1/2

Step-by-step explanation:

Setting the denominator equal to zero and factoring, we get:

x^2 - 11x + 2 = 0

Determine all horizontal asymptotes of f(x) = (x - 2)/(x^2 + 2x + 2)

To find the horizontal asymptotes of f(x), we need to examine the limit of f(x) as x approaches positive or negative infinity.

As x approaches infinity, the terms involving x^2 and 2x become insignificant compared to x^2. Thus, we can simplify the function by ignoring the terms containing x:

f(x) ≈ x/x^2 = 1/x

As x approaches negative infinity, we can make a similar simplification:

f(x) ≈ -x/x^2 = -1/x

Therefore, we can conclude that the function f(x) has two horizontal asymptotes, y = 0 and y = -1.

Determine all vertical asymptotes of f(x) = (x - 2)/(x^2 - 11x + 2)

To find the vertical asymptotes of f(x), we need to look for values of x that make the denominator of f(x) equal to zero. These values would make the function undefined.

Approximately 53.47% of prospective employees who test positive actually use illegal drugs.

we will use a tree diagram and the given information: 6% of prospective employees actually use illegal drugs, the false positive rate is 5%, and the false negative rate is 10%.
Step 1: Draw a tree diagram:
- First level: divide into two branches, one for "Uses Drugs (6%)" and one for "Does Not Use Drugs (94%)".
- Second level: under "Uses Drugs", divide into two branches, "Tests Positive (90%)" and "Tests Negative (10%)". Under "Does Not Use Drugs", also divide into two branches, "Tests Positive (5%)" and "Tests Negative (95%)".
Step 2: Calculate the probabilities:
- Probability of using drugs and testing positive: 0.06 * 0.9 = 0.054
- Probability of not using drugs and testing positive: 0.94 * 0.05 = 0.047
Step 3: Determine the percentage of prospective employees who test positive and actually use illegal drugs:
- Add the probabilities of testing positive (both using and not using drugs): 0.054 + 0.047 = 0.101

The correct option is A. The volume is 6.77 cubic units

The function and interval given are f(x) = (x - 1)^-1/4 and the x-axis on the interval (1, 6].

We want to find the volume of the solid of revolution when the region is rotated about the x-axis.

Let's consider the graph of the function: graph{(x-1)^(-1/4) [-10, 10, -5, 5]}

To set up the integral to find the volume of the solid of revolution, we can use the disk method.

We need to integrate the area of each disk perpendicular to the x-axis from x = 1 to x = 6.

The area of a disk is given by the formula: A = πr²

where r is the radius of the disk and is equal to f(x) in this case.

Therefore, the area of a disk is: A = πf(x)²

Let's substitute f(x) into this formula and integrate from x = 1 to x = 6 to get the volume of the solid.

We have The integral that should be used to find the volume of the solid is given as:

V = ∫₁⁶ πf(x)² dx

We substitute f(x) = (x - 1)^(-1/4) into this expression and integrate to get the volume.

We have: V = ∫₁⁶ π(x - 1)^(-1/2) dx

Let u = x - 1, so that du/dx = 1 and dx = du.

When x = 1, u = 0, and when x = 6, u = 5.

Therefore, we have: V = ∫₀⁵ πu^(-1/2) du= 2π[u^(1/2)]₀⁵= 2π(√5 - 1) ≈ 6.77 cubic units.

The volume of the solid of revolution when the region is rotated about the x-axis is approximately 6.77 cubic units.

Thus, the correct option is A. The volume is 6.77 cubic units.

If we divide 5 by any other integer, then the remainder will be a non-zero positive integer.

Step-by-step explanation:

Answer: The unit value of a cubic centimeter (cm^3) is the same as the metric measurement of a milliliter (mL).

This is because 1 milliliter is equal to 1 cubic centimeter. In other words, if you have a cube that measures 1 centimeter on each side, its volume would be 1 cubic centimeter, which would also be equivalent to 1 milliliter of volume.

This relationship between cm^3 and mL is commonly used in scientific and medical measurements involving liquids and gases.

The unit value of a cubic centimeter (cc) is equivalent to one milliliter (mL) in the metric system. Both cubic centimeters and milliliters are used to measure volume, and their conversion is straightforward: 1 cc = 1 mL.

The metric system uses base units such as meters, liters, and grams, and applies prefixes like kilo-, centi-, and milli- to indicate larger or smaller units of measurement.
Cubic centimeters are often used to measure the volume of solid objects or the capacity of containers, while milliliters are more commonly used to measure the volume of liquids. However, both units represent the same volume and can be used interchangeably.
It is important to understand the difference between volume measurements and other metric measurements, such as length or mass. For instance, meters are used to measure length or distance, and grams are used to measure mass or weight. These units cannot be directly converted to cubic centimeters or milliliters, as they represent different physical properties.
In summary, a cubic centimeter (cc) is a unit of volume in the metric system that is equivalent to one milliliter (mL). Both units can be used to measure volume, and they have a simple conversion of 1 cc = 1 mL. Understanding the relationship between these units and other metric measurements is essential for accurately quantifying and comparing different physical properties.

Step-by-step explanation:

If we have 84 feet of streamers. You cut 24 pieces that are each 1/2 yard long then 48 feet of streamers we left.

A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.

Given that we have a 84 feet of streamers.

You cut 24 pieces that are each 1/2 yard long.

Need to find the feet of streamers we left.

We know that 1 yard is equal to 3 feet.

Therefore, 1/2 yard is equal to 1.5 feet.

The total length of the streamers that were cut is:

24 pieces x 1.5 feet/piece = 36 feet

To find out how much streamer is left, we can subtract the length of the cut streamers from the total length we started with:

84 feet - 36 feet = 48 feet

Therefore, you have 48 feet of streamers left.
