Answer:

  yes, the rates are proportional

Step-by-step explanation:

You want to know if $120 over 36 days is a rate proportional to $10 over 3 days.

A proportion is a statement that two ratios are equal. Here, the ratios of interest can be reduced to lowest terms and compared:

  $120/(36 days) = (12×10)/(12×3) $/day = 10/3 $/day

  $10/(3 days) = 10/3 $/day . . . . . . the same ratio

The rates of money raising are proportional.

A stem and leaf plot is a graphical representation of data that allows us to see how many data points fall into certain ranges. It is similar to a histogram, but instead of bars, it uses numbers to display the data.

In a stem and leaf plot, the numbers are separated into two parts: the stem, which includes all the digits except for the last one, and the leaf, which is the last digit. For example, if we have the numbers 23, 25, 26, 27, and 29, the stems would be 2 and 2, 2 and 6, and 2 and 7, and the leaves would be 3, 5, 6, 7, and 9.

The stem and leaf plot is useful because it allows us to see the distribution of the data and identify outliers or clusters of data points. It is also easy to read and interpret, making it a popular tool for data analysis. Overall, the stem and leaf plot is an effective way to display and analyze numerical data.

An ice cream shop has 10 flavors and one can choose 4 different flavors. The question asks for the total number of possible flavor combinations.Therefore, we need to find the number of ways in which 4 flavors can be chosen from 10 flavors.

In such cases where order does not matter and repetitions are not allowed, we can use the formula for combinations which is as follows:C(n, r) = n! / (r! (n - r)!)Where n is the total number of items, r is the number of items being chosen at a time and ! represents the factorial function.

Using this formula we can find the total number of possible flavor combinations. Substituting the values in the above formula, we get:C(10, 4) = 10! / (4! (10 - 4)!)C(10, 4) = (10 * 9 * 8 * 7) / (4 * 3 * 2 * 1)C(10, 4) = 210Hence, there are 210 possible flavor combinations when one can choose 4 different flavors

.Explanation:The formula to be used for this type of question is combination. Combination is the method of selecting objects from a set, typically without replacement (without putting the same item back into the set) and where order does not matter. The formula for combination is given by C(n,r)=n!/(r!(n-r)!).

The linear equation is $1.72 + 20*x = $43.52

And the solution is x = $2.09

Here the information we have is:

Cameron bought a bag of popcorn for $1.72 and a 20 bottles of juice, and we know that the total cost before tax was $43.52

Now, if we define x as the cost of each bottle of juice, then the cost for the 20-pack is 20 times x, then we can write the linear equation:

$1.72 + 20*x = $43.52

Solving that linear equation we can get the value of x:

20*x = $43.52 - $1.72 = $41.80

x = $41.80/20  =$2.09

Thus, we conclude that each bottle costs $2.09.

Alternating Series Estimation Theorem with n = 1255, we have|S - S1255| < |an+1|wherea

n+1 = |1256|/5(1256)/5

This is accurate to more than four decimal places, so we have S ≈ S1255 ≈ 2.2830. Thus, the approximate sum of the series, accurate to four decimal places, is 2.2830.

The Alternating Series Estimation Theorem is a mathematical theorem that provides a way to approximate the sum of a given alternating series. When trying to approximate the sum of an alternating series, the formula can be used. It works with alternating series in which the terms decrease in absolute value.ExplanationFirst, we need to verify the condition of the Alternating Series Estimation Theorem, which is the following:if limn→∞|an+1/an|<1 then ∑n=1∞(−1)n+1anconverges.Since we have an=n/5, we must compute|

an+1/an|=|(n+1)/5/n|

=1/(5n)+1/5

We want to find a value of n such that|an+1/an|<1/(2n).

Therefore, we want to solve the inequality

1/(5n)+1/5<1/(2n)

Solving for n, we getn>2, which means the series converges. Thus, we can apply the Alternating Series Estimation Theorem. The formula of the Alternating Series Estimation Theorem states that|Sn - S| < an+1, where Sn is the sum of the first n terms, S is the actual sum of the series, and an+1 is the absolute value of the first neglected term.

The first term is a1 = 5 and the signs alternate. Therefore, a2 = -5/2,

a3 = 5/3,

a4 = -5/4, and so on.

We want to approximate the sum of the series to four decimal places, so we need to find a value of n such that|an+1| = |n+1|/5(n+1)/5 < 0.0001.

Solving for n, we get n > 1254, so n = 1255.

We have∑n=1∞n5(−1)n+1≈S1255where

S1255 = 5 - 5/2 + 5/3 - 5/4 + ··· - 5/2510 + 5/2511 < S < 5 - 5/2 + 5/3 - 5/4 + ··· - 5/2511 + 5/2512

Using the Alternating Series Estimation Theorem with n = 1255, we have

|S - S1255| < |an+1|

where

an+1 = |1256|/5(1256)/5

= 1/25105So|S - S1255| < 1/25105

This is accurate to more than four decimal places, so we have S ≈ S1255 ≈ 2.2830. Thus, the approximate sum of the series, accurate to four decimal places, is 2.2830.

The correct option is c) Easier interpretation. One of the main advantages of simple models is their ease of interpretation. Simple models tend to have fewer parameters and less complex mathematical equations, making it easier to understand and interpret how the model is making predictions.

This interpretability can be valuable in various domains, such as medicine, finance, or legal systems, where it is important to have transparent and understandable decision-making processes.

Complex models, on the other hand, often involve intricate relationships and numerous parameters, which can make it challenging to comprehend the underlying reasoning behind their predictions. While complex models can sometimes offer higher accuracy or make more detailed predictions, they often sacrifice interpretability in the process.

The correct solution to the equation is -13.

-12x + 12 = -3(5x + 8)

Split the right-hand side,

-12x + 12 = -15x + 24 (This line have error, instead of + there will be - )

Shifted the values of x to the left-hand side and the constant values to the right-hand side,

3x + 12 = 24

3x = 12

x= 4, which is the incorrect value of x.

The correct solution to the equation,

-12x + 12 = -3(5x + 8)

Step-by-step explanation:

None of the statements are true for the given angle θ = 2π/3.

For the given angle θ = 2π/3, let's evaluate the statements:

1. cos(theta) = √3/2

To determine if this statement is true, we can calculate the cosine of θ:

cos(2π/3) = -1/2

The statement cos(theta) = √3/2 is not true for θ = 2π/3.

2. The measure of the reference angle is 30°.

The reference angle is the positive acute angle between the terminal side of the angle and the x-axis. Since the given angle θ = 2π/3 is in the second quadrant, the reference angle cannot be 30°.

3. The measure of the reference angle is 45°.

Similar to the previous statement, since θ = 2π/3 is in the second quadrant, the reference angle cannot be 45°.

4. The measure of the reference angle is 60°.

Again, considering the quadrant of θ = 2π/3, the reference angle cannot be 60°.

5. tan(theta) = -√3

To verify this statement, we can calculate the tangent of θ:

tan(2π/3) = √3

The statement tan(theta) = -√3 is not true for θ = 2π/3.

In summary, none of the statements are true for the given angle θ = 2π/3.
