find the missing side x
Answer:
[tex]\sqrt{968}[/tex]
Step-by-step explanation:
Since this is a right triangle, we are able to use pythagorean theorem, a^2+b^2=c^2. In this case x would be the "c", so 22^2+22^2=x^2. Isolate the variable and solve for x. 484+484=x^2
968=x^2

An insurance policy sells for $600. Based on past data, an average of 1 in 50 policyholders will file a $5,000 claim, and average of 1 in 100 policyholders will file a $10,000 claim, and an average of 1 in 200 policyholders will file a $30,000 claim. What is the expected value per policy sold?
Answer:
$250
Step-by-step explanation:
Calculation to determine the expected value per policy sold
Expected value per policy sold =$600-(1/50)*$5,000-(1/100)*$10,000-(1/200)*$30,000
Expected value per policy sold =$600-$100-$100-$150
Expected value per policy sold =$250
Therefore the expected value per policy sold will be $250

From her eye, which stands 1.75 meters above the ground, Myesha measures the angle of elevation to the top of a prominent skyscraper to be 19 degrees
. If she is standing at a horizontal distance of 337 meters from the base of the skyscraper, what is the height of the skyscraper? Round your answer to the nearest hundredth of a meter if necessary.
The height of the skyscraper is approximately 115.25 meters (rounded to the nearest hundredth of a meter).
To find the height of the skyscraper, we can use trigonometry and the information provided about the angle of elevation and the horizontal distance.
Let's denote the height of the skyscraper as h. We are given that Myesha's eye height above the ground is 1.75 meters, and she measures the angle of elevation to be 19 degrees.
In a right triangle formed by Myesha's eye, the top of the skyscraper, and a point on the ground directly below the top of the skyscraper, the angle of elevation (θ) is the angle between the line of sight from Myesha's eye to the top of the skyscraper and the horizontal ground.
The opposite side of the triangle is the height of the skyscraper (h), and the adjacent side is the horizontal distance from Myesha to the base of the skyscraper (337 meters).
Using the trigonometric function tangent (tan), we can set up the following equation:
tan(θ) = h / 337
Since we know the value of the angle of elevation (θ = 19 degrees), we can substitute it into the equation:
tan(19 degrees) = h / 337
Now we can solve for h:
h = tan(19 degrees) * 337
Using a calculator or trigonometric tables, we find that tan(19 degrees) is approximately 0.34202. Substituting this value into the equation:
h = 0.34202 * 337
h ≈ 115.25

Let a/m and b/n be rational numbers expressed in lowest terms. Prove that (an + bm)/(mn) is in lowest terms if and only if m and n are relatively prime.
If m and n are relatively prime, the numerator (an + bm) and denominator (mn) have no common factors other than 1, and therefore, (an + bm)/(mn) is in lowest terms.
To prove that (an + bm)/(mn) is in lowest terms if and only if m and n are relatively prime, we will need to establish two separate claims:
Claim 1: If (an + bm)/(mn) is in lowest terms, then m and n are relatively prime.
Claim 2: If m and n are relatively prime, then (an + bm)/(mn) is in lowest terms.
Proof of Claim 1:
Let's assume that (an + bm)/(mn) is in lowest terms. This means that the numerator (an + bm) and the denominator (mn) have no common factors other than 1.
Suppose m and n are not relatively prime, which means they have a common factor greater than 1.
Let's say that factor is d, where d > 1. Then we can express m and n as follows: m = dx and n = dy, where x and y are integers.
Now, we rewrite the numerator (an + bm) as follows:
an + bm = an + b(dx) = n(a + bx/d)
Since m = dx and n = dy, we have (an + bm)/(mn) = (n(a + bx/d))/(dx * dy) = (a + bx/d)/(xy).
We can see that both the numerator (a + bx/d) and the denominator (xy) have the factor d.
This contradicts our assumption that (an + bm)/(mn) is in lowest terms, as they have a common factor greater than 1.
Therefore, m and n must be relatively prime.
Proof of Claim 2:
Now, let's assume that m and n are relatively prime, which means they have no common factors other than 1.
To show that (an + bm)/(mn) is in lowest terms, we need to demonstrate that its numerator and denominator have no common factors other than 1.
Let's suppose that the numerator (an + bm) and the denominator (mn) have a common factor d, where d > 1.
This implies that d divides both an + bm and mn.
Since d divides mn, we can express m and n as follows: m = dx and n = dy, where x and y are integers.
Now, let's rewrite the numerator (an + bm) as follows:
an + bm = an + b(dx) = n(a + bx/d)
We can see that d divides both n and the expression (a + bx/d). Therefore, d also divides the numerator (an + bm).
However, we initially assumed that (an + bm)/(mn) is in lowest terms, which means the numerator and denominator have no common factors other than 1. This contradicts the assumption that they have a common factor d > 1.
Thus, if m and n are relatively prime, the numerator (an + bm) and denominator (mn) have no common factors other than 1, and therefore, (an + bm)/(mn) is in lowest terms.
By proving both Claim 1 and Claim 2, we have established that (an + bm)/(mn) is in lowest terms if and only if m and n are relatively prime.

2. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30.
Step-by-step explanation:
100: 14,800
10: 14,780
1: 14,780
1000: 15,000
Find all solutions to the equation 34 – 38 = 3 where a, ß are positive integers (or show there are none). (6) Find all solutions where x and y are integers to the diophantine equation 1/x + 1/y =1/5
a) There are no solutions to the equation.
To find all solutions to the equation 34 - 38 = 3, we can simplify the equation:
34 - 38 = 3
-4 = 3
However, this equation is not true, as -4 is not equal to 3. Therefore, there are no solutions to the equation.
b) Now, let's consider the diophantine equation 1/x + 1/y = 1/5, where x and y are integers. To find all solutions, we can follow these steps:
1: Multiply both sides of the equation by 5xy to eliminate the denominators:
5y + 5x = xy
2: Rearrange the equation:
xy - 5x - 5y = 0
3: Apply Simon's Favorite Factoring Trick:
Add 25 to both sides to complete the square:
xy - 5x - 5y + 25 = 25
xy - 5x - 5y + 25 = 25
(xy - 5x - 5y + 25) + 25 = 25 + 25
(x - 5)(y - 5) = 50
4: List all possible factor pairs of 50:
(1, 50), (2, 25), (5, 10), (-1, -50), (-2, -25), (-5, -10)
5: Solve for x and y in each factor pair:
For (x - 5)(y - 5) = 50:
If x - 5 = 1 and y - 5 = 50, then x = 6 and y = 55.
If x - 5 = 2 and y - 5 = 25, then x = 7 and y = 30.
If x - 5 = 5 and y - 5 = 10, then x = 10 and y = 15.
If x - 5 = -1 and y - 5 = -50, then x = 4 and y = -45.
If x - 5 = -2 and y - 5 = -25, then x = 3 and y = -20.
If x - 5 = -5 and y - 5 = -10, then x = 0 and y = -5.
Therefore, the solutions to the diophantine equation 1/x + 1/y = 1/5, where x and y are integers, are:
(x, y) = (6, 55), (7, 30), (10, 15), (4, -45), (3, -20), (0, -5).

A pet store receives 7 boxes of car food. Each box has 48 cans. The store wants to put the cans in equal stacks of 8 cans. Draw a bar model to help you find how many stacks can be formed
We can form a total of 42 stacks of 8 cans each from the 7 boxes of cat food received by the pet store.
Now, We can use a bar model to represent the total number of cans and the number of stacks that can be formed.
First, let's find the total number of cans:
7 boxes x 48 cans/box = 336 cans
Now, let's use a bar model to represent this total:
| 336 cans of food |
Next, we want to find how many stacks of 8 cans we can form. We can use a separate bar model to represent the size of each stack:
| 42 stacks of 8 cans each |
Hence, The number of stacks that can be formed, we need to divide the total number of cans by the number of cans in each stack:
336 cans ÷ 8 cans/stack = 42 stacks
So the final bar model looks like this:
| 336 cans of food | = | 42 stacks of 8 cans each |
Therefore, we can form a total of 42 stacks of 8 cans each from the 7 boxes of cat food received by the pet store.

Step-by-step explanation:
You have a green house. The green house is made completely of glass, except
for the door. The entire building is 15 feet tall. The height of the vertical walls is 10 ft. The
green house is 20 ft long (on side with door) and 16 feet wide. The triangles that make up the
roof are isosceles triangles (both sides are equal and height is measured at the middle of the base).
The door is 8 feet wide and 7 feet tall. Answer each of the following questions about your greenhouse.
1. How much glass is used to make this greenhouse?
The height of the vertical walls is 10 ft=480 sq ft. The triangles that make up the roof are isosceles triangle 80 sq ft. The greenhouse uses 504 square feet of glass to construct.
To calculate the amount of glass used to make the greenhouse, to determine the total surface area of the glass panels.
The greenhouse consists of four vertical rectangular walls and two triangular roof sections.
The total surface area of the vertical walls calculated by adding the areas of each wall. Since the greenhouse is rectangular, the height of the walls is 10 ft, and the total width of the walls (including the door) is 16 ft + 8 ft = 24 ft.
Area of each wall = height x width
Area of vertical walls = 2 x (height x width) = 2 x (10 ft x 24 ft) = 480 sq ft
Each roof section forms an isosceles triangle. The base of each triangle is the width of the greenhouse, which is 16 ft. The height of the triangle is the difference between the total height of the greenhouse (15 ft) and the height of the vertical walls (10 ft), which is 5 ft.
Area of each triangular roof section = 0.5 x base x height
Area of triangular roof = 2 x (0.5 x 16 ft x 5 ft) = 80 sq ft
The door is not made of glass, so we need to subtract its area from the total.
Area of the door = width x height = 8 ft x 7 ft = 56 sq ft
calculate the total glass surface area by subtracting the area of the door from the sum of the vertical walls and triangular roof sections.
Total glass surface area = (Area of vertical walls + Area of triangular roof) - Area of the door
Total glass surface area = (480 sq ft + 80 sq ft) - 56 sq ft
Total glass surface area = 504 sq ft

How many students are enrolled in a course either in calculus, discrete mathematics, data structures, 7. or programming languages at a school if there are 507, 292, 312, and 344 students in these courses, respectively; 14 in both calculus and data structures; 213 in both calculus and programming languages; 211 in both discrete mathematics 558 and data structures; 43 in both discrete mathematics and programming languages; and no student may take calculus and discrete mathematics, or data structures and programming languages, concurrently
Answer:
974
Step-by-step explanation:
Let assume that:
The set of student that took part in Calculus be = C
Those that took part in discrete mathematics be = D
Let those that took part in data structures be = DS; &
Those that took part in Programming language be = P
Thus;
{C} = 507
{D} = 292
{DS} = 312
{P} = 344
For intersections:
{C ∩ DS} = 14
{C ∩ P} = 213
{D ∩ DS} = 211
{D ∩ P} =43
{C ∩ D} = 0
{DS ∩ P} = 0
{C ∩ D ∩ DS ∩ P} = 0
According to principle of inclusion-exclusion;
{C ∪ D ∪ DS ∪ P} = {C} + {D} + {DS} + {P} - {C ∩ D} - {C ∩ DS} - {C ∩ P} - {D ∩ DS} - {D ∩ P} - {DS ∩ P}
{C ∪ D ∪ DS ∪ P} = 507 + 292 + 312 + 344 - 14 - 213 - 211 - 43 - 0
{C ∪ D ∪ DS ∪ P} = 974
Hence, the no of students that took part in either course = 974

Given information:
In a local, recreational soccer league there are 252 men and 90 women signed up to play. The organizers need to make sure that everyone is on a team, the teams are the same size, each team has the same number of males; and each team has the same number of females.
(a) To find the largest possible number of teams, we need to divide the players (252 men and 90 women) into teams, where each team has the same number of males and females. Let's find the GCD (greatest common divisor) of 252 and 90:
GCD of 252 and 90 = GCD (252,90) = 18.
Therefore, there can be a maximum of 18 teams.
(b) Since the number of teams is 18, and we have 252 men and 90 women, there will be a total of 342 players.
Now, we need to divide these 342 players into 18 teams. Each team must have an equal number of males and females. Number of males = 252, Number of females = 90.
To divide the players equally into teams, we need to find the number of males and females that can be in one team.
Number of males in one team = 252/18 = 14
Number of females in one team = 90/18 = 5
Therefore, each team will have 14 males and 5 females, and there will be a total of 19 players on each team (14 + 5).
Thus, the largest possible number of teams is 18, and there will be a total of 19 players on each team.

Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the difference between two population proportions p_1 and p_2 at the given level of significance α using the given sample statistics. Assume the sample statistics are from independent random samples.

A. Z= ______(Round to two decimal places as needed.)
B. A normal sampling distribution cannot be used, so the claim cannot be tested.
The normal sampling distribution can be used
The critical values at α = 0.05 are z₀ = -1.96 and z₀ = 1.96
The standardized test statistic is -11.652
Deciding whether the normal sampling distribution can be usedFrom the question, we have the following parameters that can be used in our computation:
Claim: p₁ = p₂, α = 0.05Sample statistics: x₁ = 32, n₁ = 119 and x₂ = 183, n₂ = 203In the above we can see that the sample sizes are greater than 30 as required by the central limit theorem
This means that the normal sampling distribution can be used and the parameters are
H₀: p₁ = p₂
H₁: p₁ > p₂
Finding the critical valueIn (a), we have
α = 0.05
The critical values at α = 0.05 are z₀ = -1.96 and z₀ = 1.96
Finding the standardized test statistic.Start by calculating the pooled sample proportion using
p = (x₁ + x₂)/(n₁ + n₂)
So, we have
p = (32 + 183)/(119 + 203)
p = 0.67
So, we have
z = (x₁/n₁ - x₂/n₂)/√[p(1 - p)/n₁ + p(1 - p)/n₂)
substitute the known values in the above equation, so, we have the following representation
z = (32/119 - 183/203)/√[0.67(1 - 0.67)/119 + 0.67(1 - 0.67)/203]
Evaluate
z = -11.652
Hence, the standardized test statistic is -11.652

Explain the relationship between evolution, natural selection and mutations.
You must write out a well thought out and cohesive explanation. Use the CER model for this answer.
Answer:
Natural selection is a mechanism, or cause, of evolution. Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations. Random mutations are the initial cause of new heritable traits.
Answer:
Darwin's theory of evolution
Charles Darwin developed a theory of evolution to explain the unity and diversity of life, based on the idea of shared common ancestors.
Natural selection
Darwin's theory was based on the mechanism of natural selection, which explains how populations can evolve in such a way that they become better suited to their environments over time.
Light colored mice are more easily seen by predators and are therefore preyed upon more. Dark mice are better adapted to their environment and better able to survive and reproduce.
Light colored mice are more easily seen by predators and are therefore preyed upon more. Dark mice are better adapted to their environment and better able to survive and reproduce.
Natural selection acting on mice population over time.
Individuals have variations within their heritable traits. Some variations make an individual better suited to survive and reproduce in their environment.
If this continues over generations, these favorable adaptations (the heritable features that aid survival and reproduction) will become more and more common in the population.
The population will not only evolve (change in its genetic makeup and inherited traits), but will evolve in such a way that it becomes adapted, or better-suited, to its environment.
Artificial selection
There are other types of selection, in addition to natural selection, that are out there in the world.
Artificial selection, also called "selective breeding”, is where humans select for desirable traits in agricultural products or animals, rather than leaving the species to evolve and change gradually without human interference, like in natural selection.

Dog breeding is a perfect example of how humans select for desirable or fashionable traits. Breeders deliberately mate parents with the hope of producing offspring with specific traits (such as color, size, ear shape, snout length, and so on).
Common mistakes and misconceptions
Evolution is not the same as adaptation or natural selection. Natural selection is a mechanism, or cause, of evolution. Adaptations are physical or behavioral traits that make an organism better suited to its environment.
Heritable variation comes from random mutations. Random mutations are the initial cause of new heritable traits. For example, a rabbit can't choose to have a different fur color. Rather, a genetic mutation causes a difference in fur color, which may help that rabbit hide better in its environment.
Natural selection acts on existing heritable variation. Natural selection needs some starting material, and that starting material is heritable variation. For natural selection to act on a feature, there must already be variation, and that variation must be able to be passed on to offspring.
Natural selection depends on the environment. Natural selection doesn't favor traits that are somehow inherently superior. Instead, it favors traits that are beneficial in a specific environment. Traits that are helpful in one environment might actually be harmful in another.
Step-by-step explanation:
To figure out the distance for a trip, you use a ruler to measure the distance from Orlando to Gainesville on the map. You measure 2.3 cm. Find the actual mileage
between the two cities, rounded to the nearest mile.

Answer:
The answer is 71
Step-by-step explanation:
Why because
1 cm /31 mi = 2.3 cm / m
1 x m = 31 x 2.3
n = 71.3
71.3 rounded to nearest mile is 71.
