The probability of being assigned a general practitioner or a doctor under the age of 50 is 11/19 or approximately 0.5789 (rounded to four decimal places).
We are given that there are 5 general practitioners (GPs) out of 19 doctors in the hospital, which means that the probability of being assigned a GP is 5/19.
We are also given that there are 9 doctors under the age of 50 out of the 19 doctors in the hospital, which means that the probability of being assigned a doctor under the age of 50 is 9/19.
However, we need to subtract the probability of being assigned a doctor who is both a GP and under the age of 50 because this group is counted twice in the above probabilities.
We are given that there are 3 doctors who are both GPs and under the age of 50. Therefore, the probability of being assigned a doctor who is both a GP and under the age of 50 is 3/19.
To use the inclusion-exclusion principle, we add the probabilities of being assigned a GP and being assigned a doctor under the age of 50, and then subtract the probability of being assigned a doctor who is both a GP and under the age of 50.
P(GP or Under 50) = P(GP) + P(Under 50) - P(GP and Under 50)
= 5/19 + 9/19 - 3/19

10. Find the measure of each missing angle.
Answer:
see explanation
Step-by-step explanation:
A segment joining the midpoints of two sides of a triangle is
parallel to the third side
∠ 1 and 144° are same- side interior angles and sum to 180° , so
∠ 1 + 144° = 180° ( subtract 144° from both sides )
∠ 1 = 36°
----------------------
∠ 2 and 56° are corresponding angles and are congruent , so
∠ 2 = 56°
-------------------------
∠ 3 and 56° are a linear pair and sum to 180°
∠ 3 + 56° = 180° ( subtract 56° from both sides )
∠ 3 = 124°
--------------------------
the sum of the 3 angles in a triangle = 180° , then
∠ 1 + ∠ 2 + ∠ 4 = 180° , that is
36° + 56° + ∠ 4 = 180°
92° + ∠ 4 = 180° ( subtract 92° from both sides )
∠ 4 = 88°
--------------------------------
∠ 5 and ∠ 1 are corresponding angles and are congruent , so
∠ 5 = 36°
----------------------------------
Answer:
m∠1 = 36° , m∠5 = 36° , m∠4 = 88° , m∠3 = 124° , m∠2= 56°
Step-by-step explanation:
m∠1 and 144° are Co-Interior angles, or the angles which are on the same side of the transveral
m∠1 + 144° = 180°
m∠1 = 36°
angle 5 and 144° are in a linear pair-
144 °+ angle 5 = 180°
m∠5 = 36°
angle 5 + 56° + angle 4 = 180° because addition of angles of a triangle is 180°
36° + 56° + angle 4 = 180°
angle 4 = 180° - 92°
angle 4 = 88°
56° and angle 3 are in a linear pair
56° + angle 3 = 180°
angle 3 = 124°
angle 3 and angle 2 are Co-Interior angles
angle 3 + angle 2 = 180°
124° + angle 2 = 180°
angle 2 = 56°

A concert venue wants to make at least $3,750.00 profit for their Saturday night show.
Adult tickets cost $10.00 and children's tickets cost $5.00. The venue can seat up to
500 people. Find three combinations of adult and children's tickets that will make the
profit goal and not be more than 500 total people. Enter your answer as ordered pairs
(A,C) separated by a comma where A is the number of adult tickets sold and C' is
the number of children's tickets sold.
Answer:
(126, 101), (127, 100), (128, 99).
Step-by-step explanation:
The profit from selling one adult ticket is $10.00 and from selling one children's ticket is $5.00.
The total profit from selling A adult tickets and C children's tickets can be represented as 10A + 5C.
The goal is to find combinations of A and C that meet the following conditions:
10A + 5C >= 3750
A + C <= 500
One way to solve this problem is to use a brute force approach and try different values of A and C until we find three combinations that meet the conditions. Another way is to use a more efficient method and find the values of A and C that maximize the number of adult tickets while still meeting the profit and seating limit conditions.
Let's start by finding the maximum number of adult tickets that can be sold while still meeting the profit goal:
10A + 5C >= 3750
10A >= 3750 - 5C
A >= 375 - 0.5C
Since C must be an integer, we can round down the value of A to the nearest integer.
For example, if C = 100, then A >= 125. If we round down A to 125, then the profit from selling 125 adult tickets and 100 children's tickets would be:
10 * 125 + 5 * 100 = 1250 + 500 = 1750
which is less than the profit goal of 3750.
If we increase C by 1, then A would increase by 0.5, and the profit would increase by 5.
So, to reach the profit goal, we need to increase C until the profit is at least 3750.
Let's try C = 101. Then A >= 125.5, which we can round down to 126.
The profit from selling 126 adult tickets and 101 children's tickets would be:
10 * 126 + 5 * 101 = 1260 + 505 = 1765
which is greater than or equal to the profit goal of 3750.
So, the first combination of adult and children's tickets that meets the profit and seating limit conditions is (126, 101).
We can repeat the same process to find the second and third combinations.
For example, the second combination could be (127, 100), and the third combination could be (128, 99).
The final answer is (126, 101), (127, 100), (128, 99).
Answer:

In the scale drawing, what is the area of the lawn (that is, the area of the whole backyard, except for the deck)?
The area of the lawn in the scale drawing is approximately 996 square feet.
1. Measure the length and width of the lawn in inches on the scale drawing.
Length = 16.5 inches
Width = 15.5 inches
2. Convert the measurements to feet by dividing the inches by 12.
Length = 16.5/12 = 1.375 feet
Width = 15.5/12 = 1.291 feet
3. Calculate the area of the lawn by multiplying the length and width.
Area = 1.375 x 1.291 = 1.75 square feet
4. Multiply the area by the scale factor (in this case, 560) to get the actual area.
Area = 1.75 x 560 = 996 square feet

based on the reference sample, what is the random match probability for the evidence sample at the fga locus?
There is a 0.06% chance that a randomly selected individual from the population would have the same genotype as the evidence sample at the FGA locus.
As a forensic scientist, one of your important tasks is to determine the likelihood that a particular piece of evidence matches a specific individual.
To determine the random match probability for the evidence sample at the FGA locus, you will need to compare it to the reference sample. The reference sample is typically obtained from a suspect or a known individual who is not a suspect in the crime. The reference sample for the FGA locus has a genotype of 16,17.
The random match probability is the probability that a randomly selected individual from the population would have the same genotype at a specific locus as the evidence sample. To calculate this probability, you will need to use the allele frequency of the FGA locus in the population. This frequency is typically obtained from a large database of individuals.
Let's assume that the allele frequency for the FGA locus is 0.03 for the 16 allele and 0.02 for the 17 allele. To calculate the random match probability, you will need to multiply these two frequencies together since the evidence sample has both alleles present. This gives us a probability of 0.0006 or 0.06%.

When the outside temperature is 30°F, the sales is $414.13
When the sale is $1,993.33, the outside temperature is 78°F
How to find the sales when the outside temperature is 30°F?
Since the equation y = 32.9x - 572.87 can be used to model the relationship between sales at a local ice cream shop, y, in dollars, and the outside temperature, x, in degrees Fahrenheit (F).
Thus, when the outside temperature is 30°F, the sales can be estimated by substituting x = 30°F into the equation and solving for y. That is:
y = 32.9x - 572.87
y = 32.9(30) - 572.87
y = 987 - 572.87
y = $414.13
Thus, when the sale is $1,993.33, the outside temperature can be estimated by substituting y = $1,993.33 into the equation and solving for x. That is:
y = 32.9x - 572.87
1,993.33 = 32.9x - 572.87
32.9x = 1,993.33 + 572.87

The sequence is a geometric sequence with a common ratio of 4.
What is a geometric sequence?
A geometric sequence is a sequence of numbers where each term is found by multiplying the previous term by a fixed non-zero number called the common ratio (r).
To determine whether the sequence is arithmetic or geometric, we can look at the differences between consecutive terms.
The difference between the second and first terms is 2 - 0.5 = 1.5.
The difference between the third and second terms is 8 - 2 = 6.
The difference between the fourth and third terms is 32 - 8 = 24.
The difference between the fifth and fourth terms is 148 - 32 = 116.
Since the differences are not constant, the sequence is not arithmetic.
To determine if it is a geometric sequence, we can look at the ratios of consecutive terms.
The ratio of the second and first terms is 2/0.5 = 4.
The ratio of the third and second terms is 8/2 = 4.
The ratio of the fourth and third terms is 32/8 = 4.
The ratio of the fifth and fourth terms is 148/32 = 4.
Since the ratios are constant, the sequence is geometric with a common ratio of 4.

2) The smallest possible value of x is 4
3) The area of the rectangle is 57 cm²
What is the rationale for the above response?(i) The perimeter of a rectangle is given by the formula P = 2(l + b), where l is the length and b is the breadth. Substituting the given values, we get:
P = 2(4x + 3 + 2x - 5) cm
P = 2(6x - 2) cm
P = 12x - 4 cm
We are given that the perimeter is at least 40 cm, so we can write the inequality:
12x - 4 ≥ 40
Simplifying this inequality, we get:
12x ≥ 44
Dividing both sides by 12, we get:
x ≥ 11/3
x ≥ 3 2/3
So the inequality reduces to x ≥ 3 2/3
II) Note that if x is a perfect square, the smallest possible value of x is 4, because 4 is the smallest perfect square.
III) Substituting x = 4 in the length and breadth of the rectangle, we get:
Length = 4x + 3 = 19 cm
Breadth = 2x - 5 = 3 cm
Therefore, the area of the rectangle is:
Area = Length x Breadth = 19 cm x 3 cm = 57 cm²
Thus, it is correct to state that the area of the rectangle is 57cm².

Next, we need to find the number of ways to draw each pair. Since the order in which the slips are drawn does not matter, each pair can be drawn in 2 different ways. So, for each of the 5 pairs, there are 2 ways to draw the pair.
Each pair of numbers can be drawn in 2 different order (the order in which the slips are drawn does not matter in this case), so the total number of ways to draw two slips so that the sum of the numbers is 12 is [tex]5 * 2 = 10[/tex].

Which statement is INCORRECT?
2x+33
4x+7
#1: The value of x is 23.
#2: The angles are alternate exterior angles.
#3: The measure of both angles is 59º.
#4: We can use 2x + 33 = 4x + 7 to solve for x.
In a circle, a 315° sector has area 504π in2. What is the radius of the circle?
Let's call the radius of the circle "r". The formula for the area of a sector of a circle is given by:
(θ/360) * π * r^2,
where θ is the central angle of the sector in degrees.
In this case, we know that the central angle is 315° and the area of the sector is 504π, so we can set up an equation as follows:
(315/360) * π * r^2 = 504π
Solving for r, we can isolate it on one side of the equation:
r^2 = 504 / (π * (315/360))
To simplify the expression on the right-hand side, we can divide both the numerator and denominator by 45 (which is a factor of both 315 and 360):
r^2 = 504 / (π * (7/8))
Finally, taking the square root of both sides gives us:
r = sqrt(504 / (π * (7/8)))
So the radius of the circle is approximately 17.14 inches.
An art teacher is making packages
a. The greatest number of packages the teacher can make using all the paintbrushes and paint is 8
b. The number of paintbrushes in each package would be 3 and the number of tubes of paints would be 5
How do we determine the number of packages?In order to determine the greatest number of packages the teacher can make using all the paintbrushes and paint, we have to determine the highest common factor of the number of brushes and the number of tubes of paint
Highest common factor is the highest factor that is common to two or more numbers:
Factors of 24 = 1,2,3,4,6,8,12 and 24
Factors of 40 = 1, 2, 4, 5, 8, 10, 20 and 40.
Common factors of 24 and 40 = 1, 2, 4, 8
Therefore, the highest common factor is 8.
The number of paintbrushes in each package:
= Number of brushes / number of package
= 24/8
= 3 brushes
The number of tubes of paint:
= number of tubes of paints / number of package
= 40 / 8
= 5 tubes of paints
Full question "An art teacher is making packages of paint brushes and paint for his. He has 24 brushes and 40 tubes of paint.

This year, Clean Machine used 4,508.8 gallons of soap. That is 16.5% less than last year, How many gallons of soap did the company use last year? (round your answer to the nearest tenth)
The soap used by the machine last year is 5399.76 gallons.
What are percentages?The denominator of a percentage (also known as a ratio or fraction) is always 100. Sam, for instance, would have received 30 out of a possible 100 points if he had received 30% on his arithmetic test. In ratio form, it is expressed as 30:100 and in fraction form as 30/100. In this case, the percentage symbol "%" is read as "percent" or "percentage." This percent symbol can always be changed to a fraction or decimal equivalent by using "divided by 100."
Let the soap used last year = x.
Then, according to the given condition:
4,508.8 = x (1 - 16.5%)
4,508.8 = x (83.5/100)
x = 4,508.8(100) / 83.5
x = 5399.76
Hence, the soap used by the machine last year is 5399.76 gallons.

suppose that you have a fair coin. you start with $0. you win 1$ each time you get a head and loose $1 each time you get tails. calculate the probability of getting $2 without getting below $0 at any time.
The probability of winning $2 without getting below $0 at any time is 1/4 or 0.25.
To calculate the probability of winning $2 without getting below $0 at any time, we can use a branching diagram to track the possible outcomes.
Starting from $0, there are two possible outcomes for the first flip: heads or tails. If the first flip heads, the outcome is $1 and there are two possible outcomes for the second flip: heads or tails. If the second flip heads, the outcome is $2 and we have won the game. If the second flip is tails, the outcome is back to $0 and we have to start over. If the first flip is tails, the outcome is $-1 and we also have two possible outcomes for the second flip: heads or tails. If the second flip heads, the outcome is back to $0 and we have to start over. If the second flip is tails, the outcome is $-2 and we have lost the game.
Putting all of the possible outcomes together, we get the following branching diagram:
H T
/ \ / \
H T H T
/ \ / \
H T T H
$2 $0 -$1 -$2
The only way to win $2 without getting below $0 at any time is to get two heads in a row. This can only happen along the top branch of the diagram, which has a probability of (1/2) * (1/2) = 1/4.
Therefore, the probability of winning $2 without getting below $0 at any time is 1/4 or 0.25.
