Yes, 5:10 and 15:30 are equivalent ratios because they simplify to the same ratio of 1:2.
Ratios represent the relationship between two or more quantities or values. When two ratios have the same simplified form, they are considered equivalent because they represent the same relationship between the quantities being compared.
In the given example, the ratios 5:10 and 15:30 can be simplified to the same ratio of 1:2. This means that both ratios represent the same relationship between the quantities being compared. Specifically, both ratios represent a comparison between two quantities where the second quantity is twice as large as the first quantity.
To simplify a ratio, we divide both the numerator and denominator by their greatest common factor (GCF). The GCF is the largest number that divides evenly into both the numerator and denominator. In this case, the GCF of 5 and 10 is 5, and the GCF of 15 and 30 is 15. Dividing both ratios by their respective GCFs results in a simplified ratio of 1:2 for both ratios.
Therefore, 5:10 and 15:30 are equivalent ratios because they represent the same relationship between quantities, and have the same simplified form.

We can conclude after answering the provided question that Therefore, function g(x) = 1(x + 3)² + 0, which is in the form a(x - h)² + k with a = 1, h = -3, and k = 0.
what is function?In mathematics, a function appears to be a connection between two sets of numbers in which each member of one set (known as the domain) corresponds to a specific member of the second set (called the range). In other words, a function takes input from a set and produces output from another. The variable x has now been frequently sometimes used represent the inputs, and the flexible y is used to represent the outputs. A formula or a graph can be used to represent a function. For example, the formula y = 2x + 1 represents a linear model in which each x-value yields a unique value of y.
So, g(x) = f(x + 3) = (x + 3)² = x² + 6x + 9.
g(x) = x² + 6x + 9
= 1(x² + 6x + 9)
= 1(x² + 6x + 9 + 9 - 9)
= 1((x + 3)² + 9 - 9)
= 1(x + 3)² + 0
Therefore, g(x) = 1(x + 3)² + 0, which is in the form a(x - h)² + k with a = 1, h = -3, and k = 0.

4. Claire is considering investing in a new business. In the first year, there is a probability of 0.2 that the new business will lose $10,000, a probability of 0.4 that the new business will break even ($0 loss or gain), a probability of 0.3 that the new business will make $5,000 in profits, and a probability of 0.1 that the new business will make $8,000 in profits.
b. If Claire’s initial investment is $1,200 and the expected value for the new business stays constant, how many years will it take for her to earn back her initial investment?
My thoughts are that if she only invests 1200 she cant be loosing 10000 like the other people said about this question in here. The business would be loosing that amount of money not her right? but that question had a like 4.8 stars so i just want to confirm that it is correct they said it is 4 years to earn the money back but i think its less than a year. approx 0.6 Thanks to anyone who helps :)
a. Yes, she will make a profit of around $300.

Therefore, the probability that a randomly selected light bulb will last between 750 and 900 hours is 0.4772, or 47.72%.
What is deviation?
The degree to which anything deviates from a norm or expected value is referred to as its deviation. The deviation of a collection of data from the average or mean value in statistics is a measurement of how dispersed the data are. Absolute deviation and standard deviation are the two different types of variance.
We may determine that, according to the 68-95-99.7 rule, 68% of the data is within one standard deviation of the mean, 95% is within two standard deviations, and 99.7% is within three standard deviations.
Here, we're trying to determine the likelihood that a randomly chosen light bulb would live between 750 and 900 hours. One standard deviation to two standard deviations above the mean define this range.
First, we need to standardize the values using the formula:
z = (x - μ) / σ
where x is the value, we want to standardize, μ is the mean, and σ is the standard deviation.
For x = 750
z = (750 - 750)/75 = 0
For x = 900
z = (900 - 750)/75 = 2
Now we need to find the area under the standard normal distribution curve between z = 0 and z = 2. We can use a table or calculator to find this area, which is approximately 0.4772.

For each of the functions below, indicate whether the function is onto, one-to-one, neither or both. If the function is not onto or not one-to-one, give an example showing why.
(a) Let A be defined to be the set {1, 2, 3, 4, 5, 6, 7, 8}. f: P(A) → P(A). For X ⊆ A, f(X) = A-X. Recall that for a finite set A, P(A) denotes the power set of A which is the set of all subsets of A. Prove with a proof.
(b) A = {a, b, c}, h: P(A) → P(A). For X ⊆ A, h(X) = X ⊕ {a}.
the function f: P(A) → P(A), where f(X) = A-X, is onto but not one-to-one.
What is a function?
A unique kind of relation called a function is one in which each input has precisely one output. In other words, the function produces exactly one value for each input value. The graphic above shows a relation rather than a function because one is mapped to two different values. The relation above would turn into a function, though, if one were instead mapped to a single value. Additionally, output values can be equal to input values.
To determine if the function f: P(A) → P(A), where f(X) = A-X, is onto, one-to-one, neither, or both, we need to consider the following:
Onto: A function is onto if every element in the codomain has a corresponding preimage in the domain. In other words, for every Y in P(A), there exists an X in P(A) such that f(X) = Y.
Let Y be any subset of A. Then, we need to find an X such that f(X) = Y. Since f(X) = A-X, we need to find an X such that A-X = Y. Solving for X, we get X = A-Y. Therefore, we can choose X = A-Y, and we have f(X) = A-(A-Y) = Y. Hence, f is onto.
Next, we need to prove that f is not one-to-one. To do this, we need to find two different sets X1 and X2 such that f(X1) = f(X2).
Hence, the function f: P(A) → P(A), where f(X) = A-X, is onto but not one-to-one.

For a $250,000 mortgage, with interest rate 6% paid over 25 years, the monthly payment is $1,610.75. After 2 monthly payments, what is the balance of the loan? Give your answer to the nearest dollar . Do not include commas or the dollar sign in your answer.
The balance of the loan after 2 monthly payments is $246,778 (rounded to the nearest dollar).
What is compounding?Compounding refers to the process of earning interest on both the principal amount and the interest earned on that principal over time. In other words, it is the process of reinvesting earnings so that those earnings can also earn money, creating a compounding effect.
Compound interest is calculated on the initial principal amount and also on the accumulated interest of previous periods. This means that the interest earned in each period is added to the principal, and the interest for the next period is calculated on the new total.
To find the balance of the loan after 2 monthly payments, we first need to calculate the total number of payments over the life of the loan. Since the loan is paid over 25 years with monthly payments, the total number of payments is:
25 years x 12 months/year = 300 months
Next, we can use the formula for the present value of an ordinary annuity to calculate the remaining balance after 2 monthly payments. The formula is:
PV = PMT x ((1 - (1 + r)⁻ⁿ) / r)
where PV is the present value or remaining balance, PMT is the monthly payment, r is the monthly interest rate, and n is the total number of payments.
The monthly interest rate is the annual interest rate divided by 12, so in this case, it is:
6% / 12 = 0.005
Plugging in the values, we get:
PV = $1,610.75 x ((1 - (1 + 0.005)⁻³⁰⁰) / 0.005)
PV = $240,902.43
This is the remaining balance after 2 monthly payments. To find the balance after the second monthly payment, we need to subtract two monthly payments from the original loan amount:
$250,000 - ($1,610.75 x 2) = $246,778.50
Therefore, the balance of the loan after 2 monthly payments is $246,778 (rounded to the nearest dollar).

= [tex]\frac{3+76}{12}[/tex];
= [tex]\frac{79}{12}[/tex];

Step-by-step explanation:
Well to add fractions, you should make the denominator (denominator means the lower part for example 4 in ¼) the same for all numbers.
Forget the 6 for now, take only ¼ and ⅓ into consideration, make it have the same denominator
For 1/4 you multiply both up and down by 3 so it will become 3/12
For 1/3, multiply both by 4, so it becomes 4/12
You now have 3/12 and 4/12, let's not forget about the 6 now.
How do you obtain 6 if you have to make 12 denominator? (If you do 12×6 you get 72 right?) so 6 = 72/12
Your answer will be obtained like this
1/4 + 6 + 1/3 = 3/12 + 72/12 + 4/12 = 79/12 and you can make it a whole number if you can.
Ans : 79/12 which is also equal to 6 and 7 over 12 (6 7/12)
Find the distance covered by a wheel of radius 1.4 m, if it makes 250 revolutions. show working too
Answer:
The distance covered by a wheel is given by the formula:
distance = circumference of the wheel x number of revolutions
The circumference of the wheel can be found using the formula:
circumference = 2πr

There are approximately 720 blue balls, 1080 red balls, 360 green balls, 540 orange balls, and 900 yellow balls in the bin.
How many of each color do you predict are in the bin?To predict how many of each color are in the bin, we can assume that the ratio of each color in the bin is the same as the ratio in the sample of 20 balls.
First, we calculate the total number of each color in the sample:
Blue: 4 balls
Red: 6 balls
Green: 2 balls
Orange: 3 balls
Yellow: 5 balls
Next, we calculate the total number of balls in the sample:
4 + 6 + 2 + 3 + 5 = 20
Now, we can set up proportions to estimate the number of each color in the bin:
Blue: (4/20) * 3600 = 720
Red: (6/20) * 3600 = 1080
Green: (2/20) * 3600 = 360
Orange: (3/20) * 3600 = 540
Yellow: (5/20) * 3600 = 900

what is arithmetic progression ?An arithmetic progression (AP) is a series of numbers where each term is created by multiplying the previous term by a fixed constant (also known as the common difference). In other words, an AP is a set of numbers whose any two consecutive terms' differences are always the same. For instance, the mathematical progression 2, 5, 8, 11, and 14 has a common difference of 3. An algebraic progression generally takes the following form: "a," "a+d," "a+2," "a+3,"... where a denotes the sequence's first word, d is its common difference, and the ellipsis (...) denotes that the series is infinite. Mathematical progressions are crucial and are utilised in many disciplines, such as algebra, calculus, and number theory.
given
We can use the arithmetic sum formula to determine the sum of the mathematical series with initial term a=2 and common difference d=3:
Sn = (n-1)d/2(2a + n-1)a
where Sn is the sequence's initial n phrases added together.
The value of the nth term can be determined by substituting n into the arithmetic calculation, a = 3n - 1:
We can use the following words to get the value of n for the final term in the sequence:
a n = 14 = 3n - 1
3n = 15
n = 5
Hence, the series contains 5 terms. Now we can calculate the sum using the arithmetic sum formula:
S5 = 5/2(2(2) + (5-1)3)
S5 = 5/2(4 + 12)
S5 = 5/2(16) (16)

What is Cosine rule?The Cosine Rule says that the square of the length of any side of a given triangle is equal to the sum of the squares of the length of the other sides minus twice the product of the other two sides multiplied by the cosine of angle included between them.
The law of cosines states that:
c² = a² + b² - 2ab cos(C)
where a, b, and c are the lengths of the sides of the triangle, and C is the angle opposite to the side c.
According to our figure,
UW²=UV²+VW²-2(UV).(VW).Cos V
UW²=1²+2.8²-2(1)(2.8).Cos 17⁰
UW²=3.49

an animal shelter has fixed weekly expenses of 750. each animal in the shelter cost an additional 6 a week. during the winter month, the weekly expenses are at the most 900. write and solve an inequality that represents the number of animal at the shelter for expenses to be at the most 900 a week
Answer:
Let's use "x" to represent the number of animals in the shelter.
The fixed weekly expenses of the animal shelter are $750, and each animal costs an additional $6 per week. Therefore, the total weekly expenses of the animal shelter would be:
Total Weekly Expenses = Fixed Weekly Expenses + (Cost Per Animal * Number of Animals)
Total Weekly Expenses = 750 + 6x
We know that during the winter month, the weekly expenses are at most $900. So we can write the following inequality to represent this situation:
Total Weekly Expenses ≤ 900
Substituting the expression for the total weekly expenses, we get:
750 + 6x ≤ 900
Simplifying this inequality, we get:
6x ≤ 150
Dividing both sides by 6, we get:
x ≤ 25
Therefore, the inequality that represents the number of animals in the shelter for expenses to be at most $900 a week is:
x ≤ 25
This means that the shelter can have at most 25 animals during the winter month for the expenses to be within the limit of $900 a week.

A construction crew has just built a new road. They built the road at a rate of 3 kilometers per week. They built 93.75 kilometers of road. How many weeks did it take them?
Answer:
31.25 weeks
Step-by-step explanation:
You want to know how many weeks it took to construct 93.75 km of road at the rate of 3 km/week.
TimeThe relation between time, rate, and quantity is ...
time = quantity/rate
time = (93.75 km)/(3 km/wk) = (93.75/3) wk = 31.25 wk
It took the crew 31.25 weeks to build 93.75 km of road.

A. Construct grouped frequency distribution for the above data.
B. Draw histogram, frequency polygon, less than and more than cumulative freq uency curve
A. To construct a grouped frequency distribution for the given data, we first need to determine the range of the data:
Range = Maximum value - Minimum value
Range = 39 - 5
Range = 34
Next, we need to decide on the width of each class interval. A common rule is to choose the number of classes to be between 5 and 20, and then choose a class width that is a convenient number. In this case, we will choose 8 classes and a class width of 5.
Class width = Range / Number of classes
Class width = 34 / 8
Class width ≈ 4.25
We can round up the class width to 5 to get a convenient number. The class intervals are:
5 - 9.99
10 - 14.99
15 - 19.99
20 - 24.99
25 - 29.99
30 - 34.99
35 - 39.99
40 - 44.99
Next, we count the number of observations that fall into each class interval. This gives us the frequency of each interval. The grouped frequency distribution is:
Class Interval Frequency
5 - 9.99 5
10 - 14.99 8
15 - 19.99 9
20 - 24.99 16
25 - 29.99 7
30 - 34.99 6
35 - 39.99 1
40 - 44.99 0
B. To draw the histogram, frequency polygon, and cumulative frequency curves, we first need to calculate the cumulative frequencies. The less than cumulative frequency is the running total of the frequencies up to each class interval, while the more than cumulative frequency is the running total of the frequencies from each class interval to the end.
Class Interval Frequency Less than Cumulative Frequency More than Cumulative Frequency
5 - 9.99 5 5 62
10 - 14.99 8 13 57
15 - 19.99 9 22 49
20 - 24.99 16 38 40
25 - 29.99 7 45 24
30 - 34.99 6 51 17
35 - 39.99 1 52 11
40 - 44.99 0 52 10
Now we can draw the graphs:
