Answer:
15 races
Step-by-step explanation:
The team has competed in 45 and has won 30. So the success rate is:
Success rate is:
[tex]Sccess\ rate=r= \frac{30}{45}*100\\ =66.7\ percent[/tex]
We have to find the number of races the team needs to win for 75% success rate
Which means that
[tex]r = \frac{30+x}{45+x} = 0.75\\[/tex]
We have to solve the equation for x
[tex]\frac{30+x}{45+x}=0.75\\ 30+x = 0.75(45+x)\\30+x=33.75+0.75x\\x-0.75x=33.75-30\\0.25x=3.75\\x=\frac{3.75}{0.25}\\ x=15[/tex]
The team needs to win 15 races to get 75% success rate ..
Karen is looking at the edge of a large circular object from a distance. From her view, the object appears as a line segment. She knows that the distances between herself and the points on the edges of what appears to be a line segment measure 25 feet. She also knows from her location, the edges form an angle at the point she is standing at that measures 45°. Find the diameter of the object that Karen is looking at.
d = 25 ft
ω = (45º) ⁄ 2 = 22.5º
sin(ω) = R ⁄ d
sin(22.5º) = R ⁄ 25
R = 9.57 feet
Diameter = 2R
Diameter = 2 • (9.57)
Diameter = 19.1 feet
Diameter = 19 feet (when rounded)

Mason has 108 feet of material to build a fence around a rectangular pool on his property. If the width of the fence must be 6 feet, what is the length of the fence in yards if he uses all 108 feet of material? A. 48 yards B. 16 yards C. 96 yards D. 32 yards
Answer:
Option A (48 yards).
Step-by-step explanation:
The perimeter of any shape other than the ellipse is given by:
Perimeter = Sum of all sides.
Since there are two pairs of lines and both lines in the pair are congruent in each other in a rectangle, the formula can be updated as:
Perimeter of a rectangle = 2L + 2W; where L is the length and W is the width.
The perimeter of the fence around the rectangular pool is 108 feet and the width of the pool is 6 feet. The length can be calculated by plugging in the values in the above equation:
108 = 2L + 2(6).
2L = 108 - 12.
L = 96/2.
L = 48 feet.
So Option A is the correct answer!!!
The length of the fence in yards, if he uses all 108 feet of material, is 48 feet if Mason has 108 feet of material to build a fence around a rectangular pool on his property.
What is a rectangle?It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.
It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
It is given that:
Mason has 108 feet of material to build a fence around a rectangular pool on his property.
As we know,
Perimeter = Sum of all sides.
The perimeter of a rectangle (P) = 2L + 2W
Here L is the length and W is the width.
P = 109 feet
W = 6 feet
108 = 2L + 2(6)
2L = 108 - 12
L = 96/2
L = 48 feet.
Thus, the length of the fence in yards, if he uses all 108 feet of material, is 48 feet if Mason has 108 feet of material to build a fence around a rectangular pool on his property.

Among the options given, the number of siblings is an example of a discrete random variable. Discrete random variables have countable values obtained from counting, not measuring. Therefore, examples like number of siblings where counts are involved are discrete.
Explanation:In the realm of probability and statistics, discrete and continuous are two classifications for random variables. They differ in the way that their possible values are characterized or measured. We can summarize it as follows: discrete random variables are countable, while continuous random variables are uncountable, bearing values that are brought about through measurement.
In the options given - hours worked at a job, weight of a child, number of siblings, length of a fish - the one that best represents an example of a discrete random variable is the number of siblings. This is an example of a discrete random variable because it involves counting (you count the number of siblings) and not measuring.
It's important to understand that the type of a random variable, whether it's discrete or continuous, depends on how it's defined. For instance, number of miles you drive to work is considered discrete as you count the miles. However, if it's the distance you drive to work, it's measured and is considered a continuous random variable.

How do you calculate the percentage of a number?
Percentage is related to 100 and tells us how much we have of a quantity compared to another one. Suppose you have 100 cars and want to know how much cars are in red color. If 70 cars are red, then 70 percent of the cars are red. In general, we can find the percentage of a number following the steps:
For this example, let's take number 200 and the percentage 20%:
STEP 1: Multiply the number by the percentage:
200 x 20 = 4000
STEP 2: Now divide the number by 100:
400/100 = 40
STEP 3: If necessary., round to the desired precision.
To calculate the percentage of a number, divide the part by the whole and multiply by 100.
Explanation:The percentage of a number is a measure of the proportion that a given quantity represents in relation to a whole, expressed as a fraction of 100. It's commonly used to express portions, ratios, and comparisons. For example, 25% of 100 is 25.
To calculate the percentage of a number, you can use the formula: (part/whole) * 100. Start by dividing the part by the whole, then multiply the result by 100. For example, if you want to find 25% of 80, you would divide 25 by 100 to get 0.25, then multiply 0.25 by 80 to get 20. So, 25% of 80 is 20.

Circle 1 is centered at (5, 8) and has a radius of 8 centimeters. Circle 2 is centered at (1, −2) and has a radius of 4 centimeters. What transformations can be applied to Circle 1 to prove that the circles are similar? Enter your answers in the boxes.
Answer:
The answer in the procedure
Step-by-step explanation:
we know that
Figures can be proven similar if one, or more, similarity transformations (reflections, translations, rotations, dilation's) can be found that map one figure onto another.
In this problem to prove circle 1 and circle 2 are similar, a translation and a scale factor (from a dilation) will be found to map one circle onto another.
we have that
Circle 1 is centered at (5,8) and has a radius of 8 centimeters
Circle 2 is centered at (1,-2) and has a radius of 4 centimeters
step 1
Move the center of the circle 1 onto the center of the circle 2
the transformation has the following rule
(x,y)--------> (x-4,y-10)
so
(5,8)------> (5-4,8-10)-----> (1,-2)
center circle 1 is now equal to center circle 2
The circles are now concentric (they have the same center)
step 2
A dilation is needed to decrease the size of circle 1 to coincide with circle 2
scale factor=radius circle 2/radius circle 1-----> 4/8----> 0.5
radius circle 1 will be=8*scale factor-----> 8*0.5-----> 4 cm
radius circle 1 is now equal to radius circle 2
therefore
A translation, followed by a dilation will map one circle onto the other, thus proving that the circles are similar

Solve for x. x3=8125 Enter your answer in the box as a fraction in simplest form.
The value of x is 20.1036 given that x³=8125. This can be obtained by using prime factorization.
Calculate the value of x:The number 8125 can be written as factors of primes as,
8125 = 5×5×5×5×13
x³ = 5×5×5×5×13
Take cube roots on both sides,
⇒ x = ∛5×5×5×5×13
x = 5∛5×13
x = 5 × 4.02072 ⇒ x = 20.1036
Hence the value of x is 20.1036 given that x³=8125.

brainly.com/question/27863878
#SPJ2
To solve the equation x^3 = 8125 for x, we need to take the cube root of both sides of the equation. The cube root of a number y, denoted as y^(1/3), is a number which, when raised to the power of 3, gives y.
So, let's calculate the cube root of 8125:
First, we can factor 8125 into its prime factors to help simplify the cube root:
8125 = 5 * 1625 = 5 * 5 * 325 = 5 * 5 * 5 * 65 = 5 * 5 * 5 * 5 * 13 (Since 65 = 5 * 13)
Now that we have the prime factorization of 8125, we can group the factors into triples:
8125 = (5 * 5 * 5) * 13
Notice that there are three 5s in one group and a leftover 13 that cannot form a triple.
The cube root of a product of factors is the product of the cube roots of those factors, so taking the cube root of both sides of the equation gives us:
x = (5 * 5 * 5)^(1/3) * 13^(1/3)
x = 5 * 13^(1/3)
Because 13 is a prime number and cannot be broken down any further, it does not have a rational cube root. As a result, 13^(1/3) is an irrational number and cannot be represented exactly as a fraction. However, we can write the exact answer as:
x = 5 * 13^(1/3)
To find an approximate rational representation, we can look for a fraction that is close to the cube root of 13. Since we cannot do this exactly without a calculator, we can only leave our final answer like this, with the understanding that the cube root of 13 remains irrational.
In conclusion, the exact result, in simplest form without using an irrational-to-rational conversion (which would not be exact), is:
x = 5 * 13^(1/3)

Answer:
A. x ≈ 9/8
Step-by-step explanation:
We can see that left side > right side at x=1 and left side < right side at x=2. So, the solution is between x=1 and x=2.
As a first approximation, we can choose x = 3/2. Left side ≈ 0.73, right = 3.5
The solution is between x=1 and x=3/2.
For the 2nd approximation, we choose x = 5/4. Left ≈ 1.28, right = 2.25
The solution is between x=1 and x=5/4.
For the 3rd approximation, we choose x = 9/8. Left ≈ 1.62, right ≈ 1.63
The solution is between x=1 and x=9/8. The next estimate will be 17/16.
Our third estimate of the solution is 9/8.

Let the goal scored by Skylar and Wyatt be x and y respectively. Now, given Wyatt scored 2 times as many goals as Skylar. Therefore,
y = 2x
Also, Together they scored 15 goals. Therefore,
x + y = 15
x + 2x = 15
3x = 15
x = 5
Thus, Skylar and Wyatt have scored 5 and 10 goals respectively.
Hence, the correct option is A.

Solve the following compound inequality: x>= -1 or x<2
Answer:
All the real numbers.
Step-by-step explanation:
We have that x≥-1 or x<2.
The 'or' means that it can be one value or another: [-1, +∞) U (-∞, 2) = ℝ. Then, the solution to the compound inequality is All the real numbers. In set notation: ℝ.
Final answer:
The compound inequality x ≥ -1 or x < 2 is satisfied by all real numbers between -1 and 2, inclusive on the -1. The solution set can be expressed as -1 ≤ x < 2 and visualized on a number line, including all numbers from -1 to just below 2.
Explanation:
To solve the compound inequality x ≥ -1 or x < 2, we need to consider the two parts of the inequality separately and then find the union of their solutions. The first inequality, x ≥ -1, represents all real numbers greater than or equal to -1. The second inequality, x < 2, represents all real numbers less than 2. Since any real number that satisfies either condition is part of the solution set, we find that the entire set of real numbers between -1 and 2, inclusive on the -1, satisfies the compound inequality.
To visualize this, we can plot the solution on a number line. The number -1 will be included in the solution set (as indicated by a closed circle or bracket), and extend to the right, towards infinity. Simultaneously, we will plot the solution for the second inequality, which starts from negative infinity and continues to the number 2, not including 2 (indicated by an open circle or parenthesis). The overlap of these two ranges gives us the final solution set for the inequality.
The solution to the compound inequality is therefore all real numbers that are greater than or equal to -1 or less than 2, which can be expressed simply as -1 ≤ x < 2.

Which statements are true of functions? Check all that apply.
All functions have a dependent variable.
All functions have an independent variable.
The range of a function includes its domain.
A vertical line is an example of a functional relationship.
A horizontal line is an example of a functional relationship.
Each output value of a function can correspond to only one input value.
Answer:
The correct statements that are true to functions are :
All functions have a dependent variable. All functions have an independent variable.These above two can be explained as : We write a function as y = f(x), where x is the independent variable, and y is dependent as it depends on x values.
A horizontal line is an example of a functional relationship.Rest all options are incorrect.
Answer:
The correct options are:
Option A: All functions have a dependent variable.
Option B: All functions have an independent variable.
Option E: A horizontal line is an example of a functional relationship.
Step-by-step explanation:
Consider the provided information.
Function: A function is a relationship where each input has only one output.
Which is denoted by "y=f(x)" where x is input value, also the variable x is independent and y is dependent.
Each input value has exactly one output value vice versa is not true.
Vertical line test: A equation is said to be a function if all vertical lines intersect the graph at most once.
Now consider the provided options:
Option A: All functions have a dependent variable.
This option is true, by the above definition of function.
Option B: All functions have an independent variable.
This option is true, by the above definition of function.
Option C: The range of a function includes its domain.
This option is false.
Understand this with the help of an example:
Consider the function [tex]y=x^2[/tex]
The range of the function is [0,∞) and domain of the function (-∞,∞).
Here range doesn't contains the domain.
Thus this option is wrong.
Option D: vertical line is an example of a functional relationship.
The equation of the vertical line is x=a where a can be any real number.
We have different values of y for a unique x also the function fails the vertical line test.
Thus the option D is False.
Option E: A horizontal line is an example of a functional relationship.
The equation of horizontal line is y=a where a can be any real number.
For each input has only one output also it satisfy the vertical line test. We will have same value of y for any x. Which satisfy the property of function.
Thus this option is true.
Option F: Each output value of a function can correspond to only one input value by definition of function.
Understand this with the help of an example:
Consider the function y=a
The function has same output value for each input value. Which is the contradictory to the option's statement.
Thus, this option is false.
The correct options are:
Option A: All functions have a dependent variable.
Option B: All functions have an independent variable.
Option E: A horizontal line is an example of a functional relationship.

Step-by-step explanation:
Jayda's house is located at (1, 5). She can walk in a straight line to get to Cristian's house. A fast-food restaurant is located at (9, 1) and partitions the way from Jayda's house to Cristian's house by a ratio of 4:1. Find the coordinate of Cristian's house.
Coordinates are the group of a number used to indicate the position of a point in a graph or at a scale.the coordinate of Cristian's house are (11,0)
Given-
Jayda's house is located at (1, 5).
A fast-food restaurant is located at (9, 1).
Fast-food restaurant partitions the way from Jayda's house to Cristian's house by a ratio of 4:1
What is the coordinate point?Coordinates are the group of a number used to indicate the position of a point in a graph or at a scale.
Let the coordinate of jadya's be A (1,5))
Let the coordinate of Cristian's be B ([tex]x_2,y_2[/tex])
Let the coordinate of fast food restaurant be R (9,1)
The ratio is 4:1. Thus m is 4 and n is 1.
The coordinate of the point B is,
[tex]x_R=\dfrac{nx_1+mx_2}{m+n}[/tex]
[tex]9=\dfrac{1\times1+4\times x_2}{1+4}[/tex]
[tex]9=\dfrac{1+4 x_2}{5}[/tex]
[tex]4 x_2=9\times 5-1[/tex]
[tex]x_2=\dfrac{44}{4} =11[/tex]
Find the other point of Critian's house,
[tex]y_R=\dfrac{ny_1+my_2}{m+n}[/tex]
[tex]1=\dfrac{1\times5+4\times y_2}{1+4}[/tex]
[tex]1=\dfrac{5+4 y_1}{5}[/tex]
[tex]4y_1=5-5[/tex]
[tex]y_1=0[/tex]
Thus the coordinate of Cristian's house are (11,0).

Find the next four terms in the arithmetic sequence.
-15, -7, 1, ...
a)7,13,19,21
b) 10,19,28,37
c)9,17,25,33
d)7,15,25,37
To find the arithmetic sequence, we can first find it's common difference by deducting the first term by the second term:
-7-(-15)
=-7+15
=8
Therefore the common difference is 8, and to find the remaining terms we can add 8 for the respective terms.
T(4) = 1+8 =9
Therefore the answer is c)9,17,25,33.
Hope it helps!
Answer: c) 9,17,25,33
Step-by-step explanation:
Use the equation [tex]a_n=a_1+d(n-1)[/tex]
Where "n" is the nth term, [tex]a_1[/tex] is the first term, "d" is the common difference and "n" is a integer greater than zero.
Find the common diference "d":
[tex]d=(-7)-(-15)\\d=8[/tex]
Then we know that:
[tex]a_1=-15\\d=8\\[/tex]
Since we need to find the next four terms and we know three terms then:
For [tex]n=4[/tex]:
[tex]a_4=-15+8(4-1))=9[/tex]
For [tex]n=5[/tex]:
[tex]a_5=-15+8(5-1))=17[/tex]
For [tex]n=6[/tex]:
[tex]a_6=-15+8(6-1))=25[/tex]
For [tex]n=7[/tex]:
[tex]a_7=-15+8(7-1))=33[/tex]

Need help with a math question
For this case we have that there are a total of 14 male students and a total of 16 female students. Thus, there is a total of 30 students distributed in the four categories.
On the other hand, we have a total of 8 Junior students.
Then, the probability of selecting a student Junior is [tex]\frac {8} {30} * 100 = 26.67[/tex]
Rounding off we have 27%
Answer:
27%
The probability that the student is junior to the nearest whole percent is 27%
Probability is defined as the likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcome
The total outcome will be the total number of students (both male and female)
Total outcome = 4+6+2+2+3+4+6+3
Total outcome = 30
Since we are to find the probability that the student is a junior.
Total Juniors = 2 + 6 = 8
Expected outcome = 8
Probability that the student is junior = 8/30
Express as a percentage:
[tex]Pr(Juniors)=\dfrac{8}{30} \times 100\%\\ Pr(Juniors)=\dfrac{800}{30}\\ Pr(Juniors)=26.66\%\\[/tex]
Hence the probability that the student is a junior is 27%.
