Which of the following is an arithmetic sequence with a common difference of +3?

The probability that your box is a winner is 1/10,000,000.

The probability that your box is a winner can be calculated as the probability of a box rattling and being a winner, divided by the probability of a box rattling.

P(Winner | Rattle) = 1/1,000,000

P(Rattle) = 1/100

P(Winner) = P(Winner | Rattle) * P(Rattle)

= (1/1,000,000) * (1/100)

= 1/10,000,000

a. The expected number of points after one roll is the average of the possible outcomes, which are 1, 2, 3, 4, 5, and 6.

The average is (1 + 2 + 3 + 4 + 5 + 6) / 6 = 3.5.

b. The expected number of points after two rolls is the average of the possible outcomes of the sum of two rolls.

For example, the possible outcome of 2 rolls could be (1,1), (1,2), (1,3), ..., (6,6).

The average of these 36 possible outcomes is 7.

c. The expected number of points after 100 rolls is the average of the possible outcomes of the sum of 100 rolls, which would be approximately 350.

This is because the expected value for each roll is 3.5, and for 100 rolls it would be 100 * 3.5 = 350.

The temperature at which the rate constant becomes five times greater than the rate constant at 275 K is 325 K.

Let's say that temperature is represented by t and the rate constant is represented by r.

Let' say r₁ = R, r₂ = 3R, t₁ = 275 K and t₂ = 300 K.

considering the relationship between rate constant and temperature is linear.

t - 300 = [(300 - 275)/(3R - R)](r -  3R)

t - 300 = (25/2R)(r - 3R)

We are asked to determine the temperature at which the rate constant becomes five times greater than the rate constant at 275 K.

t - 300 = (25/2R)(5R - 3R)

t - 300 = (25/2R)(2R)

t - 300 = 25

t = 325 K

Hence, the temperature at which the rate constant becomes five times greater than the rate constant at 275 K is 325 K.

The reason that best supports Statement 4 in the

given proof is option A. Addition Property of Equality

The statement 4, "4x + 18 = 78," is an equation that is being derived from the previous statements in the proof. The left side of the equation (4x + 18) represents the value of m/X, which was given as 4x + 18 in statement 2.

The right side of the equation (78) represents the value of m2Y, which was given as 78° in statement 3.

Therefore, statement 4 is derived by substituting the known values of m/X and m2Y into the equation m/X = m2Y, which was given as statement 1.

The reason for this substitution is the Addition Property of Equality, which states that if you add the same value to both sides of an equation, the two sides remain equal.

In this case, the same value (4x + 18) is being added to both sides of the equation m/X = m2Y, resulting in the equation 4x + 18 = 78.

To find the lowest common multiple (LCM) of 1080, 1188, and 1815, we need to find the smallest number that is a multiple of all three numbers.

One way to find the LCM is to use prime factorization. We can prime factorize each number and then multiply the highest exponent of each prime factor to get the LCM.

1080 = 2^4 * 3^3

1188 = 2^2 * 3 * 199

1815 = 5 * 11 * 163

The LCM is:

2^4 * 3^3 * 5 * 11 * 163 = 1080 * 11 * 163

So the LCM of 1080, 1188, 1815 is 207940.

Answer:

[tex]m\angle A = 44\textdegree, a = 13.9, b = 18.0[/tex]

Step-by-step explanation:

Step 1: Solve for the Missing Angle

The measures of all of the interior angles of a triangle will always add up to [tex]180\textdegree[/tex]. Therefore,

[tex]m\angle A = 180\textdegree - (m\angle B + m\angle C) = 180\textdegree - (64\textdegree + 72\textdegree) = 44\textdegree[/tex]

Step 2: Solve for the Missing Sides

When we are given the side lengths and angle measures of a triangle, we can use either the Law of Sines or the Law of Cosines to solve for the rest of the triangle.

The Law of Sines is as follows: [tex]\frac{sinA}{a} = \frac{sinB}{b} = \frac{sinC}{c}[/tex]

The Law of Cosines is as follows: [tex]c^{2} = a^{2} +b^{2} -2abcosC[/tex] (you can exchange c for a or b, respectively)

In this case, we are only given 1 side length and all 3 angle measures, so it would be more appropriate to use the Law of Sines as we need at least 2 side lengths to use the Law of Cosines.

Now that we know which formula to use, let's start by solving for [tex]a[/tex], using the given values of [tex]c=19[/tex], [tex]\angle A = 44\textdegree[/tex], and [tex]\angle C = 72\textdegree[/tex].

Substituting these values in, we get:

[tex]\frac{sinA}{a} = \frac{sinC}{c} \\ \frac{sin44\textdegree}{a} = \frac{sin72\textdegree}{19}\\a=\frac{19sin44\textdegree}{sin72\textdegree} \approx \bf 13.9[/tex]

Repeating this process for [tex]b[/tex], this time using [tex]\angle B = 64\textdegree[/tex], we get:

[tex]\frac{sinB}{b} = \frac{sinC}{c} \\ \frac{sin64\textdegree}{b} = \frac{sin72\textdegree}{19}\\b=\frac{19sin64\textdegree}{sin72\textdegree} \approx \bf 18.0[/tex]

The ratio of blue marbles to the total number of marbles is; 3:16.

The total number of marbles in the jar is 18 red + 12 blue + 20 yellow + 14 green = 64.

So, the ratio of blue marbles to the total number of marbles can be expressed as 12:64.

This ratio can be simplified by dividing both the numerator and denominator by the greatest common factor, which in this case is 4.

So, the simplified ratio becomes 12/4 : 64/4 = 3:16.

This means for every 16 marbles in the jar, 3 of them are blue.

The simplified ratio of 3:16 can be understood as a fraction, where the numerator represents the number of blue marbles and the denominator represents the total number of marbles in the jar.

This fraction can be converted to a percentage by multiplying it with 100, which gives 18.75%.

Therefore, the ratio of blue marbles to the total number of marbles is 12:64, which simplifies to 3:16.

The area under the curve between z = −2.0 and z = −1.0 is 0.1359.

We can use tables to find the area under the normal curve between two values of z.

However, tables give areas from z = 0 to z = 3.9 (beyond which there is literally no change). But as the normal curve is symmetric at z = 0, we can use it to find between any two given z values.

For example, for the area under the curve between z = −2.0 and z = −1.0, we can take values for z = 2.0 and z = 1.0; their difference will give the area between z = −2.0 and z = −1.0.

From tables for z = 1.0, we have 0.8413 and for z = 2.0, we have 0.9772 and

Hence, the Area under the curve between z = −2.0 and z = −1.0 is 0.9772−0.8413 = 0.1359.

Step-by-step explanation:

True, the general form of a large-sample 100% confidence interval for a population proportion p is where is the sample proportion of observations with the characteristic of interest.

The general form of a large-sample 100% confidence interval for a population proportion p is given by the formula:

p ± z(standard error of p)

where p is the sample proportion of observations with the characteristic of interest and z is the critical value from a standard normal distribution corresponding to the desired level of confidence (e.g. z = 1.96 for a 95% confidence interval). The standard error of p is calculated as the square root of (p(1-p)/n), where n is the sample size.

This formula is based on the central limit theorem and the assumption that the sample is random and large enough (n > 30). In this case, the distribution of p is approximately normal and the confidence interval provides a range of plausible values for the true population proportion.
