The weights of boxes of a certain brand of pasta follow an
approximately normal distribution with a mean of 16 ounces and a standard
deviation of 0.05 ounces.
What percentage of boxes have weights that are more than 1 standard
deviation above the mean? (Use the Empirical Rule 68, 95, 99.7)
a) 15%
b) 14%
c) 20%
d) 16%
Answer:
d) 16%
Step-by-step explanation:
The empirical rule states that for a normal distribution population with a mean (μ) and standard deviation (σ), the following conditions occur:
68% falls within one standard deviation μ ± σ95% falls within two standard deviation μ ± 2σ99.7% falls within three standard deviation μ ± 3σGiven μ = 16 ounce and σ = 0.05 ounce.
68% falls within one standard deviation = μ ± σ = 16 ± 0.05 = (15.95, 16.05)
the number that falls outside one standard deviation = 100% - 68% = 32%
Therefore percentage of boxes have weights that are more than 1 standard deviation above the mean = 32% / 2 = 16%
Approximately 32% of boxes have weights that are more than 1 standard deviation above the mean.
Explanation:To find the percentage of boxes that have weights more than 1 standard deviation above the mean, we can use the Empirical Rule. According to the Empirical Rule, approximately 68% of the data falls within 1 standard deviation of the mean, 95% falls within 2 standard deviations, and 99.7% falls within 3 standard deviations.
Since we want to find the percentage of boxes that have weights more than 1 standard deviation above the mean, we can subtract 68% from 100% to get 32%. So, the answer is 32%.

You roll a fair number cube. Find each probability:
2. P(2, then 2)
1. P(3, then 5)
3. P(4, then odd)
Answer:
P(2, then 2) = [tex]\frac{1}{36}[/tex]
P(3, then 5) = [tex]\frac{1}{36}[/tex]
P(4, then odd) = [tex]\frac{1}{12}[/tex]
Step-by-step explanation:
Given: A fair number cube is rolled
To find: P(2, then 2) , P(3, then 5) , P(4, then odd)
Solution:
Probability refers to chances of occurrence of some event.
Probability = Number of favourable outcomes/Total number of outcomes
Sample space = [tex]\left \{ 1,2,3,4,5,6 \right \}[/tex]
Total number of outcomes = 6
P(2, then 2) = P(2)P(2) = [tex]\frac{1}{6}(\frac{1}{6})=\frac{1}{36}[/tex]
P(3, then 5) = P(3)P(5) = [tex]\frac{1}{6}(\frac{1}{6})=\frac{1}{36}[/tex]
Odd numbers out of the sample space = [tex]\left \{ 1,3,5 \right \}[/tex]
P(4, then odd) = P(4)P(odd) = [tex](\frac{1}{6})(\frac{3}{6} )=\frac{1}{12}[/tex]
To calculate the probability of rolling specific numbers on a fair, six-sided die, multiply the probabilities for each individual roll. P(2, then 2) and P(3, then 5) are both 1/36. P(4, then odd) is calculated as P(4) multiplied by the combined probability of rolling an odd number, resulting in 1/12.
Understanding Probability with a Fair Number Cube:
When rolling a fair, six-sided die, each outcome has an equal probability of occurring. Specifically, the probability (P) of any one number, such as a 2 or a 3, is 1/6 since it is a fair die. When considering sequential rolls, we have to calculate the probability of each event happening one after another, which involves multiplying the probabilities of the individual events.
P(2, then 2) = P(2) * P(2) = (1/6) * (1/6) = 1/36.P(3, then 5) = P(3) * P(5) = (1/6) * (1/6) = 1/36.P(4, then odd) involves the probability of rolling a 4 first, and then an odd number, which could be a 1, 3, or 5. The probability for each odd number is 1/6, and since there are three odd numbers, the combined probability of rolling an odd number is 3/6 or 1/2. Therefore, P(4, then odd) = P(4) * P(odd) = (1/6) * (1/2) = 1/12.Thus, to find the probability of rolling specific numbers or combinations on a number cube, you can calculate each probability separately and then combine them as needed using multiplication.
Ben collected data from a group of 12 people. He measured each persons resting heart rate and recorded the average number of hours each person exercised per week. He created a scatter plot to show the data he collected. Based on the scatter plot, what is the best prediction of the resting heart rate, in beats per minute, of a person who exercises an average of 8 hours each week?
To predict the resting heart rate of a person who exercises 8 hours per week, you can find the corresponding point on the scatter plot that represents 8 hours of exercise and read off the corresponding resting heart rate value.
Explanation:A scatter plot is used to show the relationship between two sets of data. In this case, Ben collected data on the resting heart rate and average hours of exercise per week for 12 people. Based on the scatter plot, we can make a prediction of the resting heart rate for a person who exercises an average of 8 hours per week. To do this, we can find the point on the scatter plot that corresponds to an average of 8 hours of exercise per week and then determine the corresponding resting heart rate.
Let's find the point on the scatter plot that represents an average of 8 hours of exercise per week.
Find the x-coordinate of the point on the scatter plot that corresponds to 8 hours of exercise per week (horizontal axis).From the x-coordinate, find the corresponding y-coordinate (vertical axis), which represents the resting heart rate.Once you have the corresponding point, you can read off the resting heart rate value in beats per minute.

Answer:
the answer is B
Step-by-step explanation:
did the question on test
The visiting team took fewer shots than the home team, as inferred by comparing the medians represented by the line in each box plot.
Explanation:When comparing the medians of the two data sets from the box plots provided by a hockey coach, an inference that can be made is that the visiting team took more shots than the home team. This is determined by comparing the median number of shots, which is indicated by the line dividing the box within each box plot. For the home team, the median is at 22 shots, while for the visiting team, the median is at 18 shots. Since the median represents the middle value of the data set, having a lower median suggests that the visiting team took fewer shots on average than the home team.

The formula a=119e^0.027t models the population of a particular city, in thousands, t years after 1998, when will the population of the city reach 178 thousand
Answer:
By year 2092
Step-by-step explanation:
In this question, we are asked to calculate the year at which the population of the city will reach 178,000
The equation that models the population of the city is given as;
A = 119e^0.027t
Here, we plug A to be 178,000
178000 = 119e^0.027t
we take the natural logarithm of both sides)
ln 178,000 = ln (119e^0.027t)
12.09 = 0.027t ln 119
12.09/ln 119 = 0.027t
2.53 = 0.027t
t = 2.53/0.027
t = 93.7 which is approximately 94 years
Since t is number of years after 1998, the exact time the population will reach 178,000 will be 1998 + 94 years = 2,092
Answer:
The population of the city will reach 178 thousand almost 15 years after 1998, that is, in the last months of 2012.
Step-by-step explanation:
The equation to be solved is:
[tex]178 = 119\cdot e^{0.027\cdot t}[/tex]
Now, the variable is cleared with the help of algebraic handling:
[tex]\frac{178}{119} = e^{0.027\cdot t}[/tex]
[tex]\ln \frac{178}{119} = 0.027\cdot t[/tex]
[tex]t = 37.037\cdot \ln \frac{178}{119}[/tex]
[tex]t \approx 14.913\,yr[/tex]
The population of the city will reach 178 thousand almost 15 years after 1998, that is, in the last months of 2012.
If a cone with a diameter of 10 m has a surface area of 190.6m2, find its slant height. Round to the nearest tenth.
Slant Height = m
Answer: The slant height of the cone is 65.6 m
Step-by-step explanation:
Given: The diameter of a cone = 10 m
Surface area of cone = 190.6 m²
To find: Slant height
Diameter of cone = 10 m
Therefore Radius of cone = [tex]\dfrac{\text {Diameter }}{2} = \dfrac{10}{2} =5m[/tex]
As we know that surface area of a cone is given by
[tex]S.A. = \pi r(l+r)[/tex]
Where S.A. is surface area , r is the radius of cone and l is the slant height of the cone.
Let Slant height = l
So we have
[tex]190.6 = \dfrac{22}{7} \times 5 ( 5+l)\\\\\Rightarrow 5+l= \dfrac{190.6 \times 7}{22}\\\\\Rightarrow l= \dfrac{1334.2}{22}+5\approx 60.64+5 = 65.64\approx65.6[/tex]
Hence the slant height of the cone is 65.6 m

Two triangular pyramids are similar the volume of the large pyramids is 729cm and the volume of the smaller pyramids is 64 cm . If the perimeter of the base of the similar pyramids is 8 cm what is the perimeter of the base of the larger pyramids
Answer:
18 cm for larger base
Step-by-step explanation:
For similar figures, there is a formula regarding volume, area, and length
Large: small = y: x for length
large: small = (y^3) / (x^3) for volume
729 cm cube/ 64 cm cube = large : small
9: 4 = large: small by length
large/ 8cm = 9/ 4
large = 8*(9/4) = 2*9 = 18 cm

It has been decided that 100 people need to be surveyed to decide the publics opinion on a school building project. A student suggests that they survey the first 100 people who enter the school. Do you think that this proposed way of sampling is an unbiased way to perform the survey?
Answer:
The proposed way of sampling is a biased way to perform the survey.
Step-by-step explanation:
Convenience sampling is a kind of non-probability sampling method that comprises of the sample being taken from that portion of the population that is near to hand. In this type of sampling method, all items doesn’t have an equivalent chance of being selected, which doesn’t comprises of random collection of items.
Convenience sampling is where we take in items which are easy to reach.
Convenience sampling consists of selection bias, i.e.e the bias involved in the sample due to inappropriate selection procedures.
For example, randomly selecting 4 people sitting near him to guesstimate the mean age of the class is a convenience sampling example. or gathering information on customer satisfaction by interviewing 6 randomly selected customers from a local store is an illustration of convenience sampling.
In this case, the sample suggested by the students consists of surveying the first 100 people who enter the school, about the public opinion on a school building project.
This is an example of convenience sample.
So, there is a selection bias present in the sample.
Thus, the proposed way of sampling is a biased way to perform the survey.

The difference between two numbers is 12. Four times the larger number decreased by 25 equals 48 increased by 3 times the smaller number. Find the numbers.
The larger number is 37 and the smaller number is 25.
Explanation:To solve this problem, let's assume that the larger number is x and the smaller number is y.
According to the problem, x - y = 12 and 4x - 25 = 48 + 3y. We can solve this system of equations by substituting the value of x from the first equation into the second equation.
Substituting x = y + 12 into the second equation, we get 4(y + 12) - 25 = 48 + 3y. Simplifying this equation, we have 4y + 48 - 25 = 48 + 3y. By combining like terms, we get 4y + 23 = 48 + 3y. Subtracting 3y from both sides, we obtain y + 23 = 48. Finally, subtracting 23 from both sides, we find y = 25. Plugging this value into the first equation, we can solve for x: x - 25 = 12. Adding 25 to both sides, we get x = 37.Therefore, the larger number is 37 and the smaller number is 25.
