Reduced odds for rolling a 2, 4, or 5: 1:1
Reduced odds against rolling a 2, 4, or 5: 1:1
To determine the reduced odds for and against rolling a 2, 4, or 5 on a fair six-sided die, we need to calculate the probabilities of these events.
Step 1: Calculate the probability of rolling a 2, 4, or 5.
There are three favorable outcomes (rolling a 2, 4, or 5) out of a total of six possible outcomes.
[tex]\[ P(\text{rolling a 2, 4, or 5}) = \frac{3}{6} = \frac{1}{2} \][/tex]
Step 2: Calculate the probability of not rolling a 2, 4, or 5.
There are three unfavorable outcomes (rolling a 1, 3, or 6) out of a total of six possible outcomes.
[tex]\[ P(\text{not rolling a 2, 4, or 5}) = \frac{3}{6} = \frac{1}{2} \][/tex]
Step 3: Calculate the odds for rolling a 2, 4, or 5.
Odds for an event are given by the ratio of the number of favorable outcomes to the number of unfavorable outcomes.
[tex]\[ \text{Odds for rolling a 2, 4, or 5} = \frac{\text{Number of favorable outcomes}}{\text{Number of unfavorable outcomes}} = \frac{3}{3} = 1:1 \][/tex]
Step 4: Calculate the odds against rolling a 2, 4, or 5.
Odds against an event are given by the ratio of the number of unfavorable outcomes to the number of favorable outcomes.
[tex]\[ \text{Odds against rolling a 2, 4, or 5} = \frac{\text{Number of unfavorable outcomes}}{\text{Number of favorable outcomes}} = \frac{3}{3} = 1:1 \][/tex]
Therefore, The reduced odds for and the reduced odds against the event of rolling a fair die and getting a 2, 4, or 5
Reduced odds for rolling a 2, 4, or 5: 1:1
Reduced odds against rolling a 2, 4, or 5: 1:1

There are 190 students taking band, chorus, or both. If there are 180 students taking band and 60 students in both band and chorus, how many students are only in chorus?
70
60
10
120
The answer would be 10. I know this because I got it right on my assignment. Have a great day!
If there are 180 students taking band and 60 students in both band and chorus, then 180-60=120 students are taking only band.
Now:
120 students are taking band;60 students are taking both band and chorus;190 students in total.Then 190-(120+60)=190-180=10 students are taking only chorus.

A nut mixture of walnuts and cashew nuts at a small fair is $1.00 per pound of walnuts and $3.10 per pound of cashew nuts. Over the entire day, 134 pounds of the nut mixture were sold for $241.10. If p is the number walnuts and n is the number of cashew nuts, then the system of equations that models this scenario is: p+n=134p+3.10n=241.10 Determine the correct description and amount of pounds for walnuts and cashew nuts that were sold.
Answer: 83 pounds of walnuts and 51 pounds of cashew nuts.
Step-by-step explanation:
Let p be the amount of pounds for walnuts and n be the amount of pounds for cashew nuts that were sold.
Given : A nut mixture of walnuts and cashew nuts at a small fair is $1.00 per pound of walnuts and $3.10 per pound of cashew nuts.
Over the entire day, 134 pounds of the nut mixture were sold for $241.10.
Then, system of equation represents the given situation will be :-
[tex]p+n=134----------(1)\\\\p+3.10n=241.10----------(2)[/tex]
Eliminate (1) from (2), we get
[tex]2.10n=107.1[/tex]
Divide 2.10 from both sides , we get
[tex]n=51[/tex]
Put value of n in (1), we get
[tex]p+51=134\\\\\Rightarrow\ p=134-51=83[/tex]
Hence, the correct description will be : 83 pounds of walnuts and 51 pounds of cashew nuts.

Which of the following best describes set of numbers? 6, 9, 12, 15, ... infinite alternating sequence finite geometric sequence infinite arithmetic series infinite arithmetic sequence?
Answer:
It is an infinite arithmetic sequence
Step-by-step explanation:
we are given a set of numbers:
6,9,12,15,...
As we can see that
9-6=3
12-9=3
15-12=3
So, given set of numbers are a sequence of arithmetic progression with common difference 3 and terms in the sequence are infinite.
Hence, it is an infinite arithmetic sequence

A vaccine has 90% probability of being effective in preventing a certain disease. the probability of getting the disease if the person is not vaccinated is 50%. in certain geographic region, 25% of the people get vaccinated. if a person is selected at random , find the probability that he or she will contract the disease
Answer:
The probability that someone is vaccinated and contracts the disease is (0.25)(0.1)=0.025 (it is multiplied by 0.1 because if the vaccine is 90% effective, then there is a 10% chance someone that is vaccinated can contract the disease. Add these together for the total: 0.375+0.025=0.4
There is a 40% chance that someone chosen at random will contract the disease.
Which description compares the vertical asymptote(s) of Function A and Function B correctly?
Function A: f(x)= 1/ x+4
Function B
Both functions have a vertical asymptote at x=−4 .
Function A has a vertical asymptote at x = 1.
Function B has a vertical asymptote at x = 3.
Function A has a vertical asymptote at x = 4.
Function B has a vertical asymptote at x = 2.
Function A has a vertical asymptote at x=−4x=−4 .
Function B has a vertical asymptote at x = 2.
Function A has a vertical asymptote at x = -4.
The graph B has vertical asymptote is 2.
We have given function
A : f(x)=1/(x+4)
Since the rational function has the vertical asymptote at x=-4 then the denominator of function f(x) contains the term (x+4)
Function B :
What is the vertical asymptote?
A vertical asymptote is is a vertical line that guides the graph of function but is not part of it.
So from the graph we can see that the graph does not pass from the point at x=2
Therefore, the vertical asymptote is 2.

How can you express (15 + 30) as a multiple of a sum of whole numbers with no common factor? 2 × (7.5 + 15) 3 × (5 + 10) 5 × (3 + 6) 15 × (1 + 2)
The sum of 15+30 = 45 and can be expressed as a multiple of prime factors:
(3^2)5
So (15+30) could be expressed as 9*5, but it can not be expressed as a non-repeating multiple of prime factors.
Which of the following is an advantage of an observational study over a sample survey? A)Observational studies are not dependent on people’s responses, which may not be truthful.
B)Observational studies involve the random selection of subjects.
C)Observational studies do not manipulate variables.
D)Observational studies do not involve treatments.
Observational studies involve the random selection of subjects.
What is an observational study?An observational study is used in subjects like epidemiology, social sciences, psychology, and statistics to draw inferences from a sample to a population where the independent variable is not under the researcher's control due to ethical concerns or logistical restrictions.
Observational studies are ones in which a researcher makes observations about his thoughts and views. He observes the risk and other effects before the actual test takes place.
This is usually the initial phase of research where observations are made for the suitability of certain things that are to be researched. There is an initial feasibility test conducted to identify whether the further research process is beneficial or not.
Therefore Observational studies involve the random selection of subjects.

△XYZ∼△DEF , YZ is 10 meters, XZ is 15 meters, and EF is 8 meters.
What is DF ?
____ m
Answer:
The measure of KL is 12 meters.
Step-by-step explanation:
It is given that △XYZ∼△DEF.
The corresponding sides of two similar triangles are proportional.
[tex]\frac{YZ}{EF}=\frac{XZ}{DF}[/tex]
[tex]\frac{10}{8}=\frac{15}{DF}[/tex]
[tex]10\times DF=15\times 8[/tex]
Divide both sides by 10.
[tex]DF=\frac{120}{10}[/tex]
[tex]DF=12[/tex]
Therefore we can say that if △XYZ∼△DEF, then the measure of DF is 12 meters.
