The ratio 1:2:3 refers to the idea we could have: 1 red, 2 green, 3 blue. The order of the colors is important. Follow the order mentioned in the 1st sentence of the instructions. That order being red:green:blue.
Then the instructions mention that there are actually 5 red (instead of 1 red). This means we multiply each part of the ratio by 5
1*5 = 5 red2*5 = 10 green3*5 = 15 blueThe ratio 1:2:3 scales up to 5:10:15
We see that there are 15 blue marbles
Find each percent of increase.round to the nearest percent 60 to 70
The percent of increase from 60 to 70 rounded to the nearest percent is 17%.
What is the percent of increase?Percent increase is simply the amount of increase from the initial value to the new value in terms of 100 parts of the initial value.
It is expressed as;
C = ((x₂ - x₁) / x₁)100%
Where x₁ is initial value and x₂ is new value
Given that;
Initial value x₁ = 60New value x₂ = 70Percentage increase C = ?Plug in the given values and solve for C.
C = ((x₂ - x₁) / x₁)100%
C = ((70 - 60) / 60) × 100%
C = ( 10 / 60) × 100%
C = 1/6 × 100%
C = 17%
Therefore, the percentage increase is 17%.

Here is the graph of a sequence:
1. Is this sequence arithmetic or geometric?
Explain how you know.
2. List at least the first five terms of the
sequence.
3. Write a recursive definition of the sequence.
A graph is a visual representation of data or information using points, lines, or bars.
How to plot the Graph?
To plot a graph, you need to have a set of x and y values that correspond to points on the graph. Once you have the data, you can use a tool such as a graphing calculator, spreadsheet software or specialized graphing software to plot the points and create the graph.
This sequence appears to be a geometric sequence. In a geometric sequence, the ratio between any two consecutive terms is always the same. In this case, the ratio between consecutive terms decreases by a factor of 1/4 each time.
The first five terms of the sequence are: (64,1), (16,2), (4,3), (2,4), (0,5)
A recursive definition of the sequence is a definition that expresses each term of the sequence in terms of one or more of the previous terms.
This definition says that each term of the sequence is the previous term divided by 4.
It's important to note that the graph you provided does not have a clear representation of the sequence, the points (64,1) (16,2) (4,3) (2,4) (0,5) does not represent a sequence as the x-coordinate does not represent the nth term of the sequence. The graph does not provide enough information to determine if it's arithmetic or geometric, or to list the first five terms of the sequence, or to write a recursive definition of the sequence.

In order to use the formula sigma x = sigma/ calculate the standard deviation of the sampling distribution of the sample mean, which of the following condition must be met? n ge 30 The population's distribution is approximately Normal. The sample size is less than 10% of the population size. I only II only III only III and either I or II All three conditions must be met.
The standard deviation of the sampling distribution of the sample mean would be 5/√30, or 0.87.
In order to use the formula sigma x = sigma/ to calculate the standard deviation of the sampling distribution of the sample mean, all three conditions must be met. The first condition is that n must be greater than or equal to 30. This is because the larger the sample size, the more likely it is that the population's distribution is approximately normal. The second condition is that the population's distribution is approximately normal. This is because the Central Limit Theorem states that when the sample size is large enough (usually n ≥ 30) the sample means will have an approximately normal distribution. The third condition is that the sample size is less than 10% of the population size. This is because samples that are too large can lead to sample means that are not representative of the population.
To calculate the standard deviation of the sampling distribution of the sample mean, we can use the following formula:
σx = σ/√n
Where σ is the population standard deviation, and n is the sample size. For example, if the population standard deviation is 5, and the sample size is 30, then the standard deviation of the sampling distribution of the sample mean would be 5/√30, or 0.87.

In a certain college, 55% of the students are women. Suppose we take a sample of two students. Use a probability tree to find the probability
(a) that both chosen students are women.
(b) that atle a stone of the two students is a woman.
The probability that both chosen students are women is 0.3025 and the probability that at least one of the two students is a woman is 0.8075.
a) Probability of both chosen students being women = P(W1 ∩ W2) = P(W1) * P(W2)
= 0.55 * 0.55 = 0.3025
b) Probability of atleast one of the two students being a woman = P(W1 ∪ W2)
= P(W1) + P(W2) - P(W1 ∩ W2)
= 0.55 + 0.55 - 0.3025 = 0.8075

Correct answers only explained
------------------------------------------------------------------
We have the original equation as
72x + 12y = 60
If we multiply by 10 we get
720x + 120y = 600
First option
---------------------------------------------------------------
We can rewrite the original equation 72x + 12y = 60 as follows
Carry 72x to the right:
12y = 60 - 72x
Divide by 12
y = 5 - 6x
Second option
---------------------------------------------------------------
Rewrite 72x + 12y = 60 as
12y + 72x = 60 (same thing)
Divide by 6:
2y + 12x = 10
Third option
---------------------------------------------------------------
Rewrite 72x + 12y = 60 as
72x = 60 - 12y
Divide by 72
x = 60/72 -12y/72
Reduce to lowest fraction
x = 5/6 - y/6

The win percentage is 79%
How to find the percentage?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
Given;
Number of games won=52
Number of games lost=14
Now, total games played= 14+52=66

Answer:
The statement "The series converges by the Integral Test" is true. The Integral Test is a method used to determine the convergence or divergence of a series. The test states that if the series is of the form:
∑(f(n))
where f(n) is a positive and continuous function defined for n ≥ 1 and is decreasing for n ≥ 1, then if the integral of f(n) from 1 to infinity converges, the series also converges. If the integral diverges, the series diverges.
It is important to note that the Integral Test is only one method of determining the convergence or divergence of a series and that it has some limitations such as it only works when the function f(n) is positive and decreasing. Also, the test is only inconclusive if the necessary conditions are not met, so statement 4 and 5 are not true.

Alessandra is having a dinner party she calculates that each meal will cost 13.00$ a person she has an 85 dollar budget for her party which inequality represents the number of people she can invite without going over her 85$ budget
She can only invite a total of six individuals, and the inequality that best captures the circumstance is 13x ≤ 85.
What is inequality?In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.
Given, Alessandra is having a dinner party she calculates that each meal will cost 13.00$ a person she has an 85 dollar budget
Let "x" be the number of people she can invite to the party
Thus,
The total cost required for the party = 13x
Since her budget is $85.
Maximum people she can invite:
13x ≤ 85
x ≤ 85/13
