Final answer:
The length of the line segment connecting points (4, -1) and (9, 7) in the coordinate plane is approximately 9.43 units, when rounded to the nearest hundredth.
Explanation:
To find the length of the line segment that connects the points (4, −1) and (9, 7) in the coordinate plane, we can use the distance formula which is derived from the Pythagorean theorem:
The distance (Δ) between two points (x1, y1) and (x2, y2) is given by:
Δ = √((x2 - x1)² + (y2 - y1)²)
Substituting the given coordinates:
Δ = √((9 - 4)² + (7 - (−1))²)
Δ = √(5² + 8²)
Δ = √(25 + 64)
Δ = √89
Using a calculator, we can find that:
Δ ≈ 9.43
Therefore, the length of the line segment is approximately 9.43 units, rounded to the nearest hundredth.

Lola takes the train from Paris to Nice. The distance between the two cities is about 900,000 meters. If the train travels at a speed of 180 kilometers per hour, how long will it take Lola to travel from Paris to Nice?
Answer:
It will take 5 hours for Lola to travel from Paris to Nice.
Step-by-step explanation:
Lola takes the train from Paris to Nice. The distance between the two cities is about 900,000 meters.
We will convert this to km.
1000 meter = 1 km
900000 meter = [tex]\frac{900000}{1000}[/tex] = 900 km
The train travels at a speed of 180 kilometers per hour, so time taken to travel from Paris to Nice will be = [tex]\frac{900}{180} =5[/tex] hours
Hence, it will take 5 hours for Lola to travel from Paris to Nice.

Answer:
Triangle with interior angles measuring 36° and 32°
Triangle with interior angles measuring 32° and 112°
Step-by-step explanation:
we know that
If two triangles are similar, then its corresponding angles are congruent
If two triangles have two equal internal angles, then the triangles are similar by AA Similarity Postulate
step 1
Calculate the measure of the third internal angle
Remember that the sum of the internal angles of a triangle must be equal to 180 degrees
so
Let
x------> the measure of the third internal angle
[tex]x\°+36\°+112\°=180\°\\ \\x=180\°-148\°\\ \\x=32\°[/tex]

Verify each triangle
case A) Triangle with interior angles measuring 36° and 32°
Is true -----> by AA Similarity Postulate
case B) Triangle with interior angles measuring 36° and 148°
Is false -----> Is not a triangle because the sum of its internal angles is greater than 180 degrees
case C) Triangle with interior angles measuring 32° and 112°
Is true -----> by AA Similarity Postulate
case D) Triangle with interior angles measuring 112° and 148°
Is false -----> Is not a triangle because the sum of its internal angles is greater than 180 degrees

Table
Food - 1/3
Housing - 1/3
Medical Care - 1/4
This year, the managers of the farm will change the fraction of the budget for housing to 1/8 but will leave the fraction of the budget for food and medical Care the same. Again, the remaining portion of the budget will be for maintenance expenses. What is the difference between the fraction of the budget for maintenance this year and last year?
Answer:
[tex]\frac{5}{24}[/tex]
Step-by-step explanation:
Previous year table .
Food - [tex]\frac{1}{3}[/tex]
Housing - [tex]\frac{1}{3}[/tex]
Medical Care - [tex]\frac{1}{4}[/tex]
So, total =[tex]\frac{1}{3}+\frac{1}{3}+\frac{1}{4}[/tex]= [tex]\frac{11}{12}[/tex]
Since we are given that the remaining portion of the budget will be for maintenance expenses.
So, maintenance expenses = [tex]1-\frac{11}{12}=\frac{1}{12[/tex]
Present year table
Food -[tex]\frac{1}{3}[/tex]
Housing -[tex]\frac{1}{8}[/tex]
Medical Care - [tex]\frac{1}{4}[/tex]
So, total =[tex]\frac{1}{3}+\frac{1}{8}+\frac{1}{4}=\frac{17}{24}[/tex]
Since we are given that the remaining portion of the budget will be for maintenance expenses.[tex]1-\frac{17}{24}=\frac{7}{24}[/tex]
The difference between the fraction of the budget for maintenance this year and last year = 7/24 - 1/12 = 5/24
Hence the difference between the fraction of the budget for maintenance this year and last year is 5/24

the area of a baseball field bounded by home plate, first base, second base, and third base, and third base is a square. If a player at first base throws the ball to a player at third base, what is the distance the player has to throw?
it's C, [tex]\sqrt{16,200}[/tex]
Final answer:
The distance a player has to throw the ball from first base to third base is the length of the diagonal of the square field. Using the Pythagorean theorem, this distance is found to be approximately 127.28 feet.
Explanation:
If the baseball field is a square, then when a player throws the ball from first base to third base, the player is throwing the ball along the diagonal of the square. To calculate the distance of the throw, which is the length of the diagonal, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b).
Since the bases form a square, both sides a and b are equal in length.
The formula we use is c = √(a² + b²), where 'c' would be the diagonal distance. If we assume the side of the square (the distance from home plate to first base, or from first base to second base, and so forth) is 90 feet, which is a standard distance in a baseball diamond, then we can plug 90 feet in for both 'a' and 'b' to calculate the diagonal:
c = √(90² + 90²)
= √(8100 + 8100)
= √(16200)
= 127.28 feet (approximately).
Therefore, the distance the player has to throw from first base to third base is about 127.28 feet.
50% of babies are born female. Olive wants to find the probability that 20 or more of the 50 babies born today were female. Use the simulation data to find the probability. Round to the nearest percent.
To find the probability that 20 or more out of 50 babies are female, use a binomial distribution with parameters n=50 and p=0.5. Calculate the cumulative probability for P(X ≥ 20). Based on a potential sample output, the probability rounded to the nearest percent is 95%.
Finding the Probability Using Binomial Distribution
The question is about finding the probability that 20 or more out of 50 babies born today are female, given that 50% of babies are born female. This scenario can be modeled using a binomial distribution.
In a binomial distribution, n represents the number of trials (in this case, 50 babies), and p represents the probability of success on a single trial (in this case, the probability of a baby being female, which is 0.5). The binomial distribution formula is:
P(X = k) = (nCk) * (p^k) * ((1-p)^(n-k))
Where nCk represents the combination of n items taken k at a time.
To find the probability that 20 or more out of 50 babies are female, we need to calculate the cumulative probability from 20 to 50:
Use a binomial table or software to find P(X ≥ 20) for n=50 and p=0.5.If using a calculator or software: P(X ≥ 20) = 1 - P(X < 20).After calculating or using a binomial table, you might get a result. For example, suppose the cumulative probability is found to be 0.9523. Rounded to the nearest percent, the probability is 95%.
Which of the following values is closest to the mean for the set of data shown below?
99, 78, 56, 11, 43, 22, 16, 31, 49, 28, 37, 29 38, 34
The mean of the given set of numbers is approximately 40.07, determined by summing all the numbers in the set and then dividing by the count of numbers in the set.
The question asks for the mean of a set of numbers. The mean is found by adding all the numbers in a set and then dividing by the total number of values in the set. To find the mean for the given data set (99, 78, 56, 11, 43, 22, 16, 31, 49, 28, 37, 29, 38, 34), we first add all the numbers:
99 + 78 + 56 + 11 + 43 + 22 + 16 + 31 + 49 + 28 + 37 + 29 + 38 + 34 = 561.
Next, we divide by the number of values, which is 14:
Mean = 561 ÷ 14 = 40.07. Therefore, the mean of the data set is approximately 40.07.
