Answers
Answer:
the numbers would be 5 and 7.
Step-by-step explanation:
"the difference of two numbers is 2."
7 - 5 = 2"their sum is 12."
7 + 5 = 12since the difference of 7 and 5 is 2 and the sum of 7 and 5 is 12, 5 and 7 are the numbers that fulfill the statement.

Suppose that mean retail price per gallon of regular grade gasoline is 3.53 with a standard deviation of and that the retail price per gallon has a bell-shaped distribution. NOTE: Please use empirical rule approximations for this problem. a. What percentage of regular grade gasoline sells for between and per gallon (to decimal)
Answers
Answer:
Incomplete question, but I gave a guide to solve using the Empirical Rule.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
It is also important to note that the normal distribution is symmetric. This means of the 68% of the measures are within 1 standard deviation of the mean, for example, 68/2 = 34% are between 1 standard deviation below the mean and the mean, and 34% are between the mean and 1 standard deviation above the mean.
In this question:
You take the mean and the standard deviation. Then you take both bounds that the percentage asks, and see how many standard deviations each are from the mean, and you then use the empirical rule to solve.
For each of the following situations, explain why the combinations rule or the permutations rule should be used. (a) Determine the number of different groups of 5 items that can be selected from 12 distinct items. Use the permutations rule, since the number of arrangements within each group is of interest. Use the combinations rule, since the number of arrangements within each group is of interest. Use the permutations rule, since only the items in the group is of concern.
Answers
Answer:
Use the combinations rule, since the number of arrangements within each group is of interest.
Step-by-step explanation:
Arrangments rule:
Number of items to be arranged is the same as the number of places.
Permutations formula:
Number of items to be arranged is different of the number of places, and the order in which the items are placed is important(AB and BA are different outcomes).
Combinations formula:
Number of items to be arranged is different of the number of places, and the order in which the items are placed is not important(AB and BA are the same outcomes).
In this question:
5 items from a set of 12. The order in which the items are chosen is not important(for example, a book and a pencil would be the same as a pencil and a book). So the combinations formula is used, and the correct option is given by:
Use the combinations rule, since the number of arrangements within each group is of interest.
A jar contains 38 red marbles numbered 1 to 38 and 38 blue marbles numbered 1 to 38 a marble is drawn at random from the jar
Answers
Answer:
[tex]P(Red) = 0.50[/tex]'
[tex]P(Odd) = 0.50\\[/tex]
Step-by-step explanation:
Given
[tex]Red = 38[/tex]
[tex]Blue = 38[/tex]
Required (Missing part of the question)
(a) The marble is red. (b) The marble is odd-numbered
Solving (a): Probability of Red.
This is calculated as:
[tex]P(Red) = \frac{Red}{Total}[/tex]
[tex]P(Red) = \frac{38}{38+38}[/tex]
[tex]P(Red) = \frac{38}{76}[/tex]
[tex]P(Red) = 0.50[/tex]
Solving (b): Probability of Odd
Since each marble type is numbered 1 to 38, then half of it are odd.
i.e. 19 odd numbered red marbles and 19 odd numbered blue marbles.
So, the probability of odd is:
[tex]P(Odd) = \frac{Odd}{Total}[/tex]
[tex]P(Odd) = \frac{19+19}{38+38}[/tex]
[tex]P(Odd) = \frac{38}{76}[/tex]
[tex]P(Odd) = 0.50\\[/tex]
