When using the empirical rule and you have a mean of 10 and a standard deviation of 1, approximately 68% of values fall between 9 and 11.
The empirical rule is also known as the three-sigma rule, which states that the values under a normal distribution curve are given by:
Approximately 68% of values fall within one standard deviation from the mean
Approximately 95% of values fall within two standard deviations from the mean
Approximately 99.7% of values fall within three standard deviations from the mean
To solve the problem, we have to calculate how many standard deviations the given values are from the mean:
Lower value = 9Mean = 10
Upper value = 11
Standard deviation = 1
Now, calculate the z-scores:
Lower z-score = (9 - 10) / 1 = -1
Upper z-score = (11 - 10) / 1 = 1
The values between 9 and 11 are within one standard deviation from the mean, so we use the first part of the empirical rule:
Approximately 68% of values fall within one standard deviation from the mean
Therefore, approximately 68% of the values fall between 9 and 11.

Determine if the given functions are even, odd or neither f(x)=x^2-7
The function f(x) = x² - 7 is an example of a function that is neither even nor odd, as it does not exhibit either type of symmetry.
To determine whether a function is even, odd, or neither, we need to examine its algebraic form and look for a particular type of symmetry.
Let's apply this concept to the given function, f(x) = x² - 7. To determine whether f(x) is even or odd, we need to evaluate f(-x) and compare it to f(x).
f(-x) = (-x)² - 7 // substitute -x for x
= x² - 7 // simplify
Comparing f(-x) to f(x), we can see that they are not equal:
f(-x) = x² - 7
f(x) = x² - 7
Since f(-x) is not equal to f(x), the function is not even. To determine whether it is odd, we need to evaluate f(-x) + f(x) and see if the result is zero.
f(-x) + f(x) = (x² - 7) + (x² - 7) // substitute -x for x in the second term
= 2x² - 14
Since f(-x) + f(x) is not equal to zero for all values of x, the function is not odd either.
Therefore, we can conclude that the given function, f(x) = x² - 7, is neither even nor odd.

if a fair die is rolled 5 times, what is the probability, rounded to the nearest thousandth, of getting at least 2 fours?
So the probability, rounded to the nearest thousandth, of getting at least 2 fours in 5 rolls of a fair die is 0.194.
What is the simple definition of probability?A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.
According to the given information:The probability of getting at least 2 fours is the sum of the probabilities of getting exactly 2, 3, 4, or 5 fours:
P(X ≥ 2) = P(X=2) + P(X=3) + P(X=4) + P(X=5)
Using the binomial formula, we can calculate each of these probabilities:
P(X=k) = (n choose k) p^k (1-p)^(n-k)
where (n choose k) is the binomial coefficient, which represents the number of ways to choose k items from n distinct items.
P(X=2) = (5 choose 2) (1/6)² (5/6)³ = 0.1608
P(X=3) = (5 choose 3) (1/6)³ (5/6)² = 0.0322
P(X=4) = (5 choose 4) (1/6)⁴ (5/6)¹ = 0.0013
P(X=5) = (5 choose 5) (1/6)⁵ (5/6)⁰ = 0.00003
Therefore,
P(X ≥ 2) = 0.1608 + 0.0322 + 0.0013 + 0.00003 = 0.1943
So the probability, rounded to the nearest thousandth, of getting at least 2 fours in 5 rolls of a fair die is 0.194.

justin recently drove to visit his parents who live 420 miles away. on his way there his average speed was 24 miles per hour faster than on his way home (he ran into some bad weather). if justin spent a total of 12 hours driving, find the two rates (in mph). round your answer to two decimal places, if needed.
Justin's speed on his way to his parents' house was 42 mph. Therefore, his speed on his way back home was 18 mph slower, or 18 mph.
Let's use x mph to represent the pace at which Justin was travelling to his parents' house. Then, as he travelled 24 mph slower owing to the terrible weather, his speed on the way back would be (x - 24) mph.
By dividing the distance he drove by his speed, one may determine how long it took Justin to drive to his parents' house, or:
Time is a function of both speed and distance.
Similar to how long it would take Justin to drive back home:
Time is a function of distance and speed (x - 24)
Justin drove for a total of 12 hours, so we can construct the following equation:
420/x + 420/(x-24) = 12
By multiplying both sides of the equation by x(x-24), we may simplify the equation and find the value of x. After some algebraic fiddling, we arrive at:
[tex]x^2 - 24x - 840 = 0[/tex]
We can find the value of x by using the quadratic formula:
[tex]x = (24 +- \sqrt{(242 + 41840)}) / 2[/tex] or x = -18
We can determine that Justin was travelling at a speed of 42 mph as he made his way to his parents' home because the speed cannot be negative. Thus, he travelled at a speed of 18 mph less on the way back home.
We can confirm the following to see if the solution is accurate:
420/42 + 420/18 = 10 + 23.33 = 33.33
Justin did, in fact, drive for a total of 12 hours, proving that our answer is accurate.

The length of the straw, which fits exactly along this diagonal, is also [tex]\sqrt{11}[/tex] inches.
What is Pythagorean theorem?
The Pythagorean theorem is a fundamental concept in mathematics that describes the relationship between the sides of a right triangle. It states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
The problem states that the straw fits exactly into the box diagonally from the bottom left corner to the top right back corner. We can visualize this diagonal as a line that runs through the center of the box, from one corner to the opposite corner.
To find the length of this diagonal, we can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the sum of the squares of the lengths of the two shorter sides (the legs) is equal to the square of the length of the longest side (the hypotenuse).
In this case, the bottom and back sides of the box form the legs of a right triangle, and the diagonal of the box forms the hypotenuse. So we can apply the Pythagorean theorem as follows:
Diagonal = [tex]\sqrt{bottom^2 + back ^2 + height ^2 }[/tex]

The probability that the second crayon drawn is blue and the first crayon drawn is blue is 1/28.
To solve this problem, we can use the conditional probability formula:
P(A and B) = P(B|A) * P(A)
where:
P(A and B) is the probability that both events A and B occur
P(B|A) is the probability of event B given that event A has already occurred
P(A) is the probability of event A occurring
In this case, we want to find the probability of selecting a blue crayon on the second draw given that the first crayon selected was blue. So we have:
P(the second crayon is blue and the first crayon is blue) = P(blue on the second draw | blue on the first draw) * P(blue on the first draw)
To find each of these probabilities, we can start by calculating the total number of possible outcomes:
Total number of outcomes = 8 crayons in the box
Next, we need to find the probability of selecting a blue crayon on the first draw:
P(blue on the first draw) = 2/8 = 1/4
After the first blue crayon has been set aside, there are only 7 crayons left in the box, so the probability of selecting a blue crayon on the second draw given that the first crayon was blue is:
P(blue on the second draw | blue on the first draw) = 1/7
Putting it all together:
P(the second crayon is blue and the first crayon is blue) = P(blue on the second draw | blue on the first draw) * P(blue on the first draw)
= (1/7) * (1/4)
= 1/28
Therefore, the probability that the second crayon drawn is blue and the first crayon drawn is blue is 1/28.

tanner is 2 years older than kiara. in 8 years the sum of their ages will be 80. how old is tanner now?
Tanner is currently 16 years old and Kiara is 14 years old. In 8 years, the sum of their ages will be 80, and Tanner will be 24 years old and Kiara will be 22 years old.
Tanner is currently 16 years old. Kiara is 14 years old. We can use algebra to solve this problem.
Let x be Tanner's age and y be Kiara's age. We can write the equation x + y = 80.
Since Tanner is two years older than Kiara, we can write x = y + 2. Substituting x for y + 2, we can write (y + 2) + y = 80.
Simplifying this equation, we get 2y + 2 = 80. We can subtract 2 from both sides of the equation, leaving us with 2y = 78. Dividing both sides by 2 gives us y = 39.
Since y represents Kiara's age, we know that Kiara is currently 39 years old. Since Tanner is two years older, we can say that Tanner is 41 years old.
Therefore, Tanner is currently 16 years old and Kiara is 14 years old. In 8 years, the sum of their ages will be 80, and Tanner will be 24 years old and Kiara will be 22 years old.

we change the shape of the graph of the function. Specifically, changing the value of "a" stretches or compresses the graph vertically, and changes the direction of the opening of the parabola.
If "a" is positive, the parabola opens upwards, and if "a" is negative, the parabola opens downwards. The larger the absolute value of "a", the more stretched or compressed the parabola becomes.
In the case of g(x) = 6x^2, "a" is positive and equal to 6, which means the graph is stretched vertically by a factor of 6 compared to the parent function. The parabola opens upwards and is narrower than the parent function.
If we were to change the value of "a" to a different positive value, for example "a" = 3, the graph would still open upwards but would be less stretched than g(x) = 6x^2. On the other hand, if we were to make "a" negative, for example "a" = -6, the graph would open downwards, and be a reflection of the graph of g(x) = 6x^2 about the x-axis.
In summary, changing the value of "a" in the quadratic function affects the vertical stretch or compression and the direction of the opening of the parabola, compared to the graph of the quadratic parent function.

What is the volume of the cone expressed in terms of pi?
Answer: V≈339.29 in
Step-by-step explanation:
the defect levels, as reported by motorola in their six sigma program, were higher than they expected from using a standard normal table for their capability calculations. why was this true? motorola found their processes followed the exponential distribution motorola allowed for failure in one tail only motorola had not allowed for a 1.5 sigma shift in the mean motorola found that six sigma efforts increased process variation
The defect levels reported by Motorola in their Six Sigma program were higher than expected because of the nature of their processes following an exponential distribution.
This means that Motorola only allowed for failure in one tail of the distribution, which increases the likelihood of failure and causes the defect levels to be higher than the standard normal table's capability calculations. Additionally, Motorola had not accounted for a 1.5 sigma shift in the mean, which also contributed to the higher defect levels. Through their Six Sigma efforts, Motorola found that their process variation had increased, which explains why their defect levels were higher than expected.

when using sample data to estimate a population-level relationship, why is it necessary to engage in hypothesis testing?
Hypothesis testing is an important step when using sample data to estimate a population-level relationship because it helps ensure that the conclusions drawn from the data are accurate.
Hypothesis testing allows us to determine the probability that the observed results are due to chance, rather than reflecting a real relationship between the variables. When constructing a hypothesis, we set up two competing hypotheses, the null and the alternative. The null hypothesis states that there is no relationship between the variables and that the observed results are due to chance. The alternative hypothesis states that there is a relationship between the variables and that the observed results are not due to chance.
We can then use the sample data to conduct a test of statistical significance to compare the results of the two hypotheses. This test helps us determine whether the observed results are due to chance or if they are significant enough to suggest a real relationship between the variables. In conclusion, hypothesis testing is essential when using sample data to estimate a population-level relationship because it allows us to determine the probability that the observed results are due to chance, rather than reflecting a real relationship between the variables.
