Answer:
4 Quarters and 11 Dimes
Step-by-step explanation:
In the first equation, we know that [tex]D=15-Q[/tex] If we plug this into the second equation, we get 25q+10(15-Q)=210. If we simplify this equation, we get 25q+150-10q=210, which can be simplified to 15q+150=210. And since 15q=60, q=4. Then, you subtract 4 from 15, to get 11 dimes. So, there are 4 quarters and 11 dimes. Hopefully, this helps!

According to a study done by a university student, the probability a randomly selected individual will not cover his or her mouth when sneezing is . Suppose you sit on a bench in a mall and observe people's habits as they sneeze. (a) What is the probability that among randomly observed individuals exactly do not cover their mouth when sneezing? (b) What is the probability that among randomly observed individuals fewer than do not cover their mouth when sneezing? (c) Would you be surprised if, after observing individuals, fewer than half covered their mouth when sneezing? Why? (a) The probability that exactly individuals do not cover their mouth is nothing. (Round to four decimal places as needed.) (b) The probability that fewer than individuals do not cover their mouth is nothing. (Round to four decimal places as needed.) (c) Fewer than half of individuals covering their mouth ▼ would would not be surprising because the probability of observing fewer than half covering their mouth when sneezing is nothing, which ▼ is is not an unusual event. (Round to four decimal places as needed.)

Answer:
a
[tex]P(X = 8) = 0.0037[/tex]
b
[tex]P(X < 5) = 0.805[/tex]
c
[tex]P(X > 6) = 0.0206[/tex]
I would be surprised because the value is very small , less the 0.05
Step-by-step explanation:
From the question we are told that
The probability a randomly selected individual will not cover his or her mouth when sneezing is [tex]p = 0.267[/tex]
Generally data collected from this study follows binomial distribution because the number of trials is finite , there are only two outcomes, (covering , and not covering mouth when sneezing ) , the trial are independent
Hence for a randomly selected variable X we have that
[tex]X \ \ \~ \ \ { B ( p , n )}[/tex]
The probability distribution function for binomial distribution is
[tex]P(X = x ) = ^nC_x * p^x * (1 -p) ^{n-x}[/tex]
Considering question a
Generally the the probability that among 12 randomly observed individuals exactly 8 do not cover their mouth when sneezing is mathematically represented as
[tex]P(X = 8) = ^{12} C_8 * (0.267)^8 * (1- 0.267)^{12-8}[/tex]
Here C denotes combination
So
[tex]P(X = 8) = 495 * 0.000025828 * 0.28867947[/tex]
[tex]P(X = 8) = 0.0037[/tex]
Considering question b
Generally the probability that among 12 randomly observed individuals fewer than 5 do not cover their mouth when sneezing is mathematically represented as
[tex]P(X < 5 ) =[P(X = 0 ) + \cdots + P(X = 4)][/tex]
=> [tex]P(X < 5 ) =[ ^{12} C_0 * (0.267)^0 * (1- 0.267)^{12-0} + \cdots + ^{12} C_4 * (0.267)^4 * (1- 0.267)^{12-4} ][/tex]
=> [tex]P(X < 5 ) = 0.02406 + 0.10516 + 0.21067 + 0.25580 + 0.20964[/tex]
=> [tex]P(X < 5) = 0.805[/tex]
Considering question c
Generally the probability that fewer than half(6) covered their mouth when sneezing(i.e the probability the greater than half do not cover their mouth when sneezing) is mathematically represented as
[tex]P(X > 6) = 1 - p(X \le 6)[/tex]
=> [tex]P(X > 6) = 1 - [P(X = 0) + \cdots + P(X =6)][/tex]
=> [tex] P(X > 6)=1 - [^{12} C_0 * (0.267)^0 * (1- 0.267)^{12-0}+ \cdots + ^{12} C_4 * (0.267)^6 * (1- 0.267)^{12-6} ][/tex]
=> [tex] P(X > 6)= 1 - [0.02406 + \cdots + 0.0519 ][/tex]
=> [tex]P(X > 6) = 0.0206[/tex]
I would be surprised because the value is very small , less the 0.05
(a )randomly observed individuals exactly do not cover their mouth when sneezing
[tex]P[x=8]=0.0037[/tex]
(b) randomly observed individuals fewer than do not cover their mouth when sneezing
[tex]P[x < 5]=0.805[/tex]
(c) fewer than half covered their mouth when sneezing
[tex]P(x > 6)=0.0206[/tex]
What will be the probability?It is given in the question that
The probability a randomly selected individual will not cover his or her mouth when sneezing is
[tex]P=0.267[/tex]
Generally, data collected from this study follows binomial distribution because the number of trials is finite, there are only two outcomes, (covering, and not covering mouth when sneezing ), the trial is independent
The probability distribution function for binomial distribution is
[tex]P(x=8)=n C_X\times p^x\times (1-p)^{n-x}[/tex]
Generally, the probability that among 12 randomly observed individuals exactly 8 does not cover their mouth when sneezing is mathematically represented as
[tex]P(x=8)=12c_8\times (0.267)^8\times (1-0.267)^{12-8}[/tex]
[tex]p(x=8)=495\times 0.000025828\times 0.2886794[/tex]
[tex]p(x=8)=0.0037[/tex]
Generally, the probability that among 12 randomly observed individuals fewer than 5 do not cover their mouth when sneezing is mathematically represented as
[tex]p(x < 5)=[p(x=0)+......+p9x=4)][/tex]
[tex]p(x < 5)=[12c_0\times(0.267)^0\times(1-0.267)^{12-0}+........+12c_4\times(0.267)^4\times (1-0.267)^{12-4}[/tex]
[tex]p(x < 5)=0.02406+0.10516+0.21067+0.25580+0.20964[/tex]
[tex]p(x < 5)=0.805[/tex]
Generally the probability that fewer than half(6) covered their mouth when sneezing(i.e the probability the greater than half do not cover their mouth when sneezing) is mathematically represented as
[tex]p(x > 6)=1-p(x\leq 6)[/tex]
[tex]p(x > 6)=1-[p(x=6)+......+p(x=6)][/tex]
[tex]p(x > 6)=1-[12c_0(0.267)^0\times(1-0.267)^{12-0}+....+12c_4\times(0.267)^6\times(1-0.267)[/tex]
[tex]p(x > 6)=1-[0.02406+.....+0.0519][/tex]
[tex]p(x > 6)=0.0206[/tex]
Thus
(a )randomly observed individuals exactly do not cover their mouth when sneezing
[tex]P[x=8]=0.0037[/tex]
(b) randomly observed individuals fewer than do not cover their mouth when sneezing
[tex]P[x < 5]=0.805[/tex]
(c) fewer than half covered their mouth when sneezing
[tex]P(x > 6)=0.0206[/tex]

Two consecutive vertices of a regular octagon are located at (1, 4) and (4,8). This octagon's perimeter is.....?
Answer:
40 units
Step-by-step explanation:
An octagon is a polygon with 8 sides. A regular octagon is an octagon in which all their sides and angles are equal to each other.
Since the vertices of a regular octagon are located at (1, 4) and (4,8), hence the length of the side is gotten using the formula for calculating the distance between two points [tex]X(x_1,y_1)\ and\ Y (x_2,y_2)[/tex].
[tex]|XY|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Hence:
[tex]Length=\sqrt{(4-1)^2+(8-4)^2}=5\ units[/tex]
Since all the sides of a regular octagon are equal, therefore:
Perimeter = 8 × length = 8 × 5 = 40 units

How could you describe the maximum the LCM between two numbers could be?
Answer:
the product of the two numbers
Step-by-step explanation:
The LCM of two numbers is their product, divided by their GCF. If their GCF is 1, then the LCM will be their product. That is the most it can be.
__
We assume you're concerned with whole numbers. For rational numbers, the GCF may be a fraction, so the LCM may be larger than the product of the numbers.
LCM(5, 6) = 5·6/GCF(5, 6) = 5·6/1 = 30
LCM(1/2, 3/4) = (1/2)(3/4)/GCF(1/2, 3/4) = (3/8)/(1/4) = 3/2

Casey has 48 red peppers and 16 yellow peppers.
If Casey wants to put the peppers into baskets so that each basket has the same number of red peppers and the same number of yellow peppera, what is the greatest number of baskets he can make? How many of each type of pepper will be in each basket?
Answer:
Casey should use 16 baskets and put 4 red peppers 1 yellow pepper into each one of them.
Step-by-step explanation:
Greatest Common Divisor (GCD)
The GCD of x and y is the maximum possible number that evenly divides both of them.
For example, GCM(36,48) is 12 because 36/12 is a whole number and 48/12 is also a whole number and 12 is the greatest of all possible candidates. Note that 6 is also a common divisor (36/6 and 48/6 are whole numbers), but it's not the maximum.
Casey has 48 red peppers and 16 yellow peppers. Since he wants to put them into baskets in such a way that each basket has the same number of red peppers and the same number of yellow peppers, we must find the greatest divisor for both numbers to maximize the number of baskets.
The GCM(48,16) is 16. Number of red peppers per basket=48/16=4. Number of yellow peppers per basket=16/16=1, thus:
Casey should use 16 baskets and put 4 red peppers 1 yellow pepper into each one of them.
For each of the following questions, say whether the random process is a binomial process or not, and explain your answer. As part of your explanation, you will want to comment on the potential validity of each of the four things that must be true for a process to be a binomial process.
a. One basketball player attempts 10 free throws and the number of successful attempts is totalled.
b. Ten different basketball players each attempt 1 free throw and the total number of successful attempts is totalled.
Answer:
a
This process follows is a binomial process
b
This process is not a binomial process
Step-by-step explanation:
Considering the first statement
One basketball player attempts 10 free throws and the number of successful attempts is totaled.
This process is a binomial process because
The number of trials is finite Each trial is independent of the other There is only two possible outcome (make a basket and make no basket The probability of making a basket and not making a basket is constant throughout the trialsOne basketball player attempts 10 free throws and the number of successful attempts is totaled.
This process is not a binomial process because chance that is the probability of success and failure will remain constant throughout the trial is not equal (what this means is that given the number of player is more than on their probability of success and failure will differ.)

which one of the following inequalities can help you
find the least possible value of b, the number of
boxes of cookies Linda must sell so she will make
more money than Carol?
Answer:
This inequality is impossible. Assuming this is realistic, Linda cannot sell part of a box of cookies and therefore cannot make less than $220.
