At a carnival game, it cost Noah $12 to toss 30 rings. Fill out a table of equivalent ratios and plot the points on the coordinate axes provided.
The table complete table that shows equivalent ratios is:
Toss Dollars
5 2
30 12
45 18
See image in the attachment that shows the points on a coordinate plane.
What are Equivalent Ratios?The ratios that give the same value when we compare them together are regarded as equivalent ratios.
For example, 2:3 is an equivalent ratio to 4:6, because 4/6 can be simplified as 2/3.
If it cost $12 to toss 30 rings, the ratio of dollars to number of toss would be: 12:30 = 2:5.
Let x = number of toss
Let y = amount in dollars
The equation that models the equivalent ratios can be written as y = 2/5x.
Therefore, when we have 2 dollars (y = 2):
2 = 2/5(x)
10 = 2x
10/2 = x
x = 5 toss
When we have 45 tosses (x = 45):
y = 2/5(45)
y = 18 dollars
The table of equivalent ratios would be:
Toss Dollars
5 2
30 12

Select all lengths that are equal to 3 yards 16 inches.
The lengths equal to 3 yards 16 inches are 3 yards, 108 inches, 3.44 yards (approximately), and 108.44 inches (approximately).
To determine the lengths that are equal to 3 yards 16 inches, we need to convert the measurements into a consistent unit. Since both yards and inches are units of length, we can convert the inches into yards or the yards into inches to find the equivalent lengths.
1 yard is equal to 36 inches (since 1 yard = 3 feet and 1 foot = 12 inches).
Therefore, 3 yards is equal to 3 * 36 = 108 inches.
Now, we can compare 108 inches to 3 yards 16 inches.
108 inches is equal to 3 yards, so it matches the given length.
To convert 16 inches into yards, we divide it by 36 since 1 yard = 36 inches. 16 inches / 36 = 0.44 yards.
Therefore, 3 yards 16 inches is equivalent to:
3 yards
108 inches
3 yards 0.44 yards (or approximately 3.44 yards)
108 inches 0.44 yards (or approximately 108.44 inches)

The functions f(m) = 18 + 0.4m and g(m) = 11.2 + 0.54m give the lengths of two differentsprings in centimeters, as mass is added in grams, m, to each separately.
STEP - BY - STEP EXPLANATION
What to do?
Graph each equation on the same set of axis.
Determine the mass that makes the spring the same length.
Determine the length of that mass.
Write a sentence comparing the two springs.
Given:
f(m) = 18 + 0.4m and g(m) = 11.2 + 0.54m
Step 1
Find the x and y-intercept of both function.
f(m) = 18 + 0.4m
f(0) = 18+0.4(0) = 18
0 = 18 + 0.4m
0.4m = -18
m=-45
The x and y -intercept of the function f(m) are (0, 18) and (-45, 0) respectively.
g(m) = 11.2 + 0.54m
g(0) = 11.2 + 0.54(0)
g(0) = 11.2
0 = 11.2+ 0.54m
0.54m = -11.2
m=20.7
The x and y - intercepts are (0, 11.2) and (20.7, 0).
Step 2
Graph the function.
Below is the graph of the function.
Observe from the graph that that the mass that makes the spring the same length is approximately 48.5 grams.
The length at that point is 37.4 centimeters.
Comparison between the two strings.
The string with the function f(m) started out longer, but does not stretch as quickly as the other spring with the function g(m).
ANSWER
b) 48.6 grams
c) 37.4 centimeters
d) The string with the function f(m) started out longer, but does not stretch as quickly as the other spring with the function g(m).
The following table (Table C2.1) is a partial listing of the sales transactions for the Watson Distributing Company for the year ended December 31, 200X. Select the first three sample items from the population using the following techniques. a. The systematic selection technique with a random starting point of 13 and a sampling interval of 30. b. The probability-proportional-to-size sampling selection technique with a random starting dollar of $17,240 and a sampling interval of $220,000. c. The random-number table selection technique using Figure 2.1 on pp. 24-25. Using the last four digits of the invoice number, begin at row (0004) and column (01), continuing across the row and then down to the beginning of the next row.
The three methods are used to select a sample from a larger population in order to make inferences about the population as a whole.
Probability-proportional-to-size sampling is a method where the probability of an item being selected is proportional to its size. In this case, the size is represented by the dollar amount of the sale.
Systematic selection involves selecting items at regular intervals. In this case, the starting point is 13 and the interval is 30. Every 30th item is selected, starting from the 13th item.
The starting dollar is $17,240 and the interval is $220,000. Every item with a sales amount that falls within the interval is selected with a probability proportional to its size.
The random-number table selection technique involves using a random number table to select items. The last four digits of the invoice number are used to determine which item is selected.
The selection process starts at row (0004) and column (01) and continues across the row and then down to the next row.
The probability of an item being selected in each method differs and is important in ensuring a representative sample is obtained.

You intend to estimate a population mean with a confidence interval. You believe the population to have a normal distribution. Your sample size is 4.
Find the critical value that corresponds to a confidence level of 99.9%. Round to three decimal places.
The critical value is 9.925, rounded to three decimal places.
How to solveTo calculate the critical value for a 99.9% confidence level with a sample size of 4, we will use the t-distribution, since the population standard deviation is unknown.
The t-distribution is used when the sample size is small (usually n < 30) and the population standard deviation is unknown.
First, find the degrees of freedom (df) for the t-distribution, which is equal to the sample size (n) minus 1:
df = n - 1df = 4 - 1df = 3Next, we need to find the critical value (t) that corresponds to a 99.9% confidence level (or a 0.999 probability) and 3 degrees of freedom. We will look this up in a t-distribution table or use a t-distribution calculator.
Using a t-distribution calculator or table, the t-score corresponding to a 99.9% confidence level (two-tailed) and 3 degrees of freedom is approximately 9.925.
So, the critical value is 9.925, rounded to three decimal places.

which expression is equivalent to X to the -4th power Y over X to the -9th power Y to the fifth power -2
The equivalent expression is \(X^5 * Y^{(-4)} - 2.\)
How to ffind the equivalent expressionThe expression can be simplified as follows:
\(X^(-4) * Y / (X^{(-9)} * Y^5) - 2\)
To simplify this expression, we can use the properties of exponents. When dividing terms with the same base, we subtract the exponents:
\(X^{(-4)} / X^{(-9)} = X^{(-4 - (-9))} = X^5\)
Similarly, when dividing terms with the same base, we subtract the exponents:
\(Y^1 / Y^5 = Y^{(1 - 5)} = Y^{(-4)}\)
Substituting these simplifications back into the expression:
\(X^5 * Y^{(-4)} - 2\)

How can u find a geometry-big circle mAB=56 mBC=59 mCD=63 mDE=63 mEF= 31
To find the measure of the geometry-big circle, we need to sum up the measures of all the arcs around the circle.
We are given the following measures:
\(\sf\:m\angle AB = 56 \\\)
\(\sf\:m\angle BC = 59 \\\)
\(\sf\:m\angle CD = 63 \\\)
\(\sf\:m\angle DE = 63 \\\)
\(\sf\:m\angle EF = 31 \\\)

Suppose u1= [2,3,1] and u2= [4,1,0]. For which value(s) of the constant k is [1,2,k] a linear combination of u1 and u2?
Answer:
The value of the constant \(k\) so that \(\vec u_{3}\) is a linear combination of \(\vec u_{1}\) and \(\vec u_{2}\) is \(\frac{7}{10}\).
Step-by-step explanation:
Let be \(\vec u_{1} = [2,3,1]\), \(\vec u_{2} = [4,1,0]\) and \(\vec u_{3} = [1, 2,k]\), \(\vec u_{3}\) is a linear combination of \(\vec u_{1}\) and \(\vec u_{3}\) if and only if:
\(\alpha_{1} \cdot \vec u_{1} + \alpha_{2} \cdot \vec u_{2} +\alpha_{3}\cdot \vec u_{3} = \vec O\) (Eq. 1)
Where:
\(\alpha_{1}\), \(\alpha_{2}\), \(\alpha_{3}\) - Scalar coefficients of linear combination, dimensionless.
By dividing each term by \(\alpha_{3}\):
\(\lambda_{1}\cdot \vec u_{1} + \lambda_{2}\cdot \vec u_{3} = -\vec u_{3}\)
\(\vec u_{3}=-\lambda_{1}\cdot \vec u_{1}-\lambda_{2}\cdot \vec u_{2}\) (Eq. 2)
\(\vec O\) - Zero vector, dimensionless.
And all vectors are linearly independent, meaning that at least one coefficient must be different from zero. Now we expand (Eq. 2) by direct substitution and simplify the resulting expression:
\([1,2,k] = -\lambda_{1}\cdot [2,3,1]-\lambda_{2}\cdot [4,1,0]\)
\([1,2,k] = [-2\cdot\lambda_{1},-3\cdot \lambda_{1},-\lambda_{1}]+[-4\cdot \lambda_{2},-\lambda_{2},0]\)
\([0,0,0] = [-2\cdot \lambda_{1},-3\cdot \lambda_{1},-\lambda_{1}]+[-4\cdot \lambda_{2},-\lambda_{2},0]+[-1,-2,-k]\)
\([-2\cdot \lambda_{1}-4\cdot \lambda_{2}-1,-3\cdot \lambda_{1}-\lambda_{2}-2,-\lambda_{1}-k] =[0,0,0]\)
The following system of linear equations is obtained:
\(-2\cdot \lambda_{1}-4\cdot \lambda_{2}= 1\) (Eq. 3)
\(-3\cdot \lambda_{1}-\lambda_{2}= 2\) (Eq. 4)
\(-\lambda_{1}-k = 0\) (Eq. 5)
The solution of this system is:
\(\lambda_{1} = -\frac{7}{10}\), \(\lambda_{2} = \frac{1}{10}\), \(k = \frac{7}{10}\)
The value of the constant \(k\) so that \(\vec u_{3}\) is a linear combination of \(\vec u_{1}\) and \(\vec u_{2}\) is \(\frac{7}{10}\).
