can be used to determine the percentage of data values that must be within one, two, and three standard deviations of the mean for data having a bell-shaped distribution. a. a boxplot b. chebyshev's theorem c. the empirical rule d. a five-number summary
The empirical rule may be used to determine the percentage of data values that must be within only one, two, and three standard deviations of the mean for data having a bell-shaped distribution.
The 68 95 99 rule, commonly referred to as the empirical rule in statistics, asserts that given normal distributions, 68% of observed data points will fall within one standard deviation from the mean, 95% will fall between two standard deviations, and 99.7% will happen within three standard deviations.
Fairly anticipate that your data will resemble a normal distribution, the empirical rule, the mean, as well as the standard deviation become even more beneficial. Determine probabilities and percentages for many events just by knowing these two statistics.
The term "empirical rule" derives from empirical research, which relies on measurements and observations of actual results rather than theory. In other words, the term "empirical" denotes a foundation in actuality.

A vending machine containing jellybeans will only dispense one jellybean at a time. Inside the container is a mixture of 24 jellybeans: 12 red, 8 yellow, and 4 green. The yellow jellybeans have a rotten egg flavor. Write each answer as a decimal rounded to the nearest thousandth and as a percent rounded to the nearest whole percentage point. Part A: What is the probability of getting a red jellybean on the first draw? Decimal: P(1 st Red )= Percent: P(1 st Red )= Part B: Let's say you did get a red jellybean on the first draw. What is the probability that you will then get a green on the second draw? Decimal: P(2 nd Green | 1st Red )= Percent: P(2 nd Green | 1st Red )= Part C: If you had gotten a yellow on the first draw, would your answer to Part B be different? Part D: What is the conditional probability of the dependent event "red then green?" Decimal: P(1st Red and 2 nd Green )= Percent: P(1 st Red and 2 nd Green )=
Part A:What is the probability of getting a red jellybean on the first draw?
Given information: Red jellybeans = 12 Yellow jellybeans = 8 Green jellybeans = 4 Total jellybeans = 24 The probability of getting a red jellybean on the first draw is:
Probability of getting a red jellybean=Number of red jellybeans/Total jellybeans=12/24=1/2=0.5
Decimal: P(1st Red)=0.5 Percent: P(1 st Red )=50%
Part B: Let's say you did get a red jellybean on the first draw.
What is the probability that you will then get a green on the second draw?
Now, the total number of jellybeans is 23, since one red jellybean has been taken out. The probability of getting a green jellybean is: Probability of getting a green jellybean=Number of green jellybeans/Total number of jellybeans=4/23=0.174 Decimal: P(2nd Green | 1st Red )=0.174 Percent: P(2nd Green | 1st Red )=17%
Part C: If you had gotten a yellow on the first draw, would your answer to Part B be different?
Yes, because there is only 1 rotten egg yellow jellybean and if it were chosen in the first draw, it would not be returned back to the container. Therefore, the total number of jellybeans would be 23 for the second draw, and the probability of getting a green jellybean would be:
Probability of getting a green jellybean=Number of green jellybeans/Total number of jellybeans=4/23=0.174
Thus, the answer would be the same as Part B.
Part D: What is the conditional probability of the dependent event "red then green?"
Given that one red jellybean and one green jellybean are selected: Probability of the first jellybean being red is 1/2
Probability of the second jellybean being green given that the first jellybean is red is 4/23
Probability of "red then green" is calculated as follows: Probability of red then green=P(Red) × P(Green|Red)= 1/2 × 4/23 = 2/23 Decimal: P(1st Red and 2nd Green )=2/23 Percent: P(1st Red and 2nd Green )=8.70%

when a cone is cut by a plane parallel to its base, a cone similar to the original is formed. what is the ratio of the volume of the smaller cone to that of the original cone?
The ratio of the volume of the smaller cone to that of the original cone is equal to the cube of the ratio of their corresponding heights, which is (h'/h)³.
Let's consider the original cone with height h and radius r. When the cone is cut by a plane parallel to its base, a smaller cone is formed with a height h' and radius r'. Since the smaller cone is similar to the original cone, the ratios of their corresponding dimensions are equal.
The height ratio between the smaller cone and the original cone is h'/h, and the radius ratio is r'/r. Since the cones are similar, these ratios are the same. Therefore, we can express the ratio of their heights as r'/r = h'/h.
The volume of a cone is given by the formula V = (1/3)πr²h. Therefore, the volume ratio of the smaller cone to the original cone is (1/3)π(r')²(h') / (1/3)πr²h, which simplifies to (r'/r)²(h'/h).
Since we know that r'/r = h'/h, we can substitute this value into the volume ratio expression, giving us (h'/h)²(h'/h) = (h'/h)³.
Thus, the ratio of the volume of the smaller cone to that of the original cone is equal to the cube of the ratio of their corresponding heights, which is (h'/h)³.

Compute the z score for the applicant. Applicant's score 21.0; Mean 18.0; Standard Deviation - 3.0 O2.0 O-10 10 O-20 O None of these
To compute the z-score for the applicant, we can use the formula:
z = (x - μ) / σ
Where:
x is the applicant's score
μ is the mean
σ is the standard deviation
Given that the applicant's score is 21.0, the mean is 18.0, and the standard deviation is -3.0, we can substitute these values into the formula to calculate the z-score.
z = (21.0 - 18.0) / (-3.0)
z = 3.0 / -3.0
z = -1.0
Therefore, the z-score for the applicant is -1.0.

Step-by-step explanation:
For A = {6, 10, 14) and B=(3,5,7) find the
relation y = 1/2 x in AxB
By taking A as our domain and B as our range, we will see that the relation is {(6, 3), (10, 5), (14, 7)}
Here we have:
A = {6, 10, 14}B = {3, 5, 7}And we want to find the relation:
y = (1/2)*x in AxB.
So, we take values from A, and we input them in the given function, and then we must see if the outcome is in B.
For each value in A we will have:
y = (1/2)*6 = 3
(6, 3)
y = (1/2)*10 = 5
(10, 5)
y = (1/2)*14 = 7

if ∑an and ∑bn are both convergent series with positive terms, then ∑anbn is convergent.T/F
If the series ∑an and ∑bn are both convergent series with positive terms, then the series ∑anbn is also convergent.
This can be proven using the Comparison Test for series convergence. Since an and bn are both positive terms, we can compare the series ∑anbn with the series ∑an∑bn.
If ∑an and ∑bn are both convergent, then their respective partial sums are bounded. Let's denote the partial sums of ∑an as Sn and the partial sums of ∑bn as Tn.
Then, we have:
0 ≤ Sn ≤ M1 for all n (Sn is bounded)
0 ≤ Tn ≤ M2 for all n (Tn is bounded)
Now, let's consider the partial sums of the series ∑an∑bn:
Pn = a1(T1) + a2(T2) + ... + an(Tn)
Since each term of the series ∑anbn is positive, we can see that each term of Pn is the product of a positive term from ∑an and a positive term from ∑bn.
Using the properties of the partial sums, we have:
0 ≤ Pn ≤ (M1)(Tn) ≤ (M1)(M2)
Hence, if ∑an and ∑bn are both convergent series with positive terms, then ∑anbn is also convergent.
Therefore, the given statement is True.

By using factoring by grouping or synthetic division, we find that \(x = -2\) is a real solution.
Find all real solutions to the polynomial equations \(x³+2x ²-5x-6=0\) and \(5x³-17x²+21x-6=0\).Checking for Rational Roots
Using the rational root theorem, the possible rational roots of the polynomial are given by the factors of the constant term (24) divided by the factors of the leading coefficient (-4).
The possible rational roots are ±1, ±2, ±3, ±4, ±6, ±8, ±12, ±24.
By substituting these values into \(f(x)\), we find that \(f(-2) = 0\). Hence, \(x + 2\) is a factor of \(f(x)\).
Dividing \(f(x)\) by \(x + 2\) using long division or synthetic division, we get:
-4x⁴ + 26x³ - 50x² + 16x + 24 = (x + 2)(-4x³ + 18x² - 16x + 12)Now, we have reduced the problem to factoring \(-4x³ + 18x² - 16x + 12\).
Attempt 2: Factoring by Grouping
Rearranging the terms, we have:
-4x³ + 18x² - 16x + 12 = (-4x^3 + 18x²) + (-16x + 12) = 2x²(-2x + 9) - 4(-4x + 3)Factoring out common factors, we obtain:
-4x³+ 18x² - 16x + 12 = 2x²(-2x + 9) - 4(-4x + 3) = 2x²(-2x + 9) - 4(3 - 4x) = 2x²(-2x + 9) + 4(4x - 3)Now, we have \(2x^2(-2x + 9) + 4(4x - 3)\). We can further factor this as:
2x²(-2x + 9) + 4(4x - 3) = 2x² (-2x + 9) + 4(4x - 3) = 2x²(-2x + 9) + 4(4x - 3) = 2x²(-2x + 9) + 4(4x - 3) = (2x² + 4)(-2x + 9)Therefore, the fully factored form of \(f(x) = -4x⁴ + 26x³ - 50x² + 16x + 24\) is \(f(x) = (x + 2)(2x² + 4)(-2x + 9)\).

\(x³ ³ + 2x² - 5x - 6 = 0\)Using polynomial division or synthetic division, we can find the quadratic equation \((x + 2)(x² + 2x - 3)\). Factoring the quadratic equation, we get \(x² + 2x - 3 = (x +

Let f be the function given by f(x) 9x. If four subintervals of equal length are used, what is the value of the right Riemann sum approximation for (x) dx?
The value of the right Riemann sum approximation for integral ∫₀² f(x) dx is (c) 60.
The right Riemann sum approximation is obtained by dividing the interval [0, 2] into four subintervals of equal length and evaluating the function at the right endpoints of each subinterval. In this case, each subinterval has a length of (2-0)/4 = 0.5. The right endpoints of the subintervals are 0.5, 1.0, 1.5, and 2.0.
To calculate the right Riemann sum, we evaluate the function at these right endpoints and sum up the values multiplied by the subinterval length.
f(0.5) = \(9^{0.5\) = 3
f(1) = 9¹ = 9
f(1.5) = \(9^{1.5\) = 27
f(2) = 9² = 27
The right Riemann sum is then
= (0.5 * f(0.5)) + (0.5 * f(1.0)) + (0.5 * f(1.5)) + (0.5 * f(2.0))
= 0.5 * (3 + 9 + 27 + 81)
= 60.

if 200 group rooms are reserved and only 160 are ultimately occupied, the pick-up rate is group of answer choices 60% 70% 80% 90%
The pick-up rate in this scenario would be 80%. This is calculated by dividing the number of rooms occupied (160) by the number of rooms reserved (200), and then multiplying by 100 to get a percentage. So, (160/200) x 100 = 80%. This means that 80% of the reserved rooms were ultimately occupied.
It's important to note that a pick-up rate of 80% is generally considered to be a good result in the hospitality industry. It indicates that the hotel was able to accurately predict the number of rooms that would be needed by the groups, and that the groups themselves followed through on their reservations. A lower pick-up rate could suggest that the hotel overestimated demand, or that some of the groups cancelled their bookings at the last minute. On the other hand, a higher pick-up rate could indicate that the hotel was too conservative in its initial estimates, or that some of the groups requested additional rooms after the initial reservation was made. Ultimately, the pick-up rate is a useful metric for assessing the accuracy of a hotel's forecasting and planning processes.
