It is possible to have a function f:A→B with an element b∈B so that f does not assign any element to b?

The probability that the customer is served by Charter with market share of 30% is equal to 34.9%.

Let A be the event that the customer is served by Charter,

and B be the event that the customer is experiencing an internet speed of 12Mbps.

Probability of A given B, which can be written as P(A|B).

Use Bayes' theorem to find P(A|B),

P(A|B) = P(B|A) × P(A) / P(B)

P(A) = 0.3 (the market share of Charter)

and P(B) = P(B/A) × P(A) + P(B / A') × P(A'),

where P(A') = 1 - P(A) = 0.7 (the market share of Xfinity).

P(B|A), the probability of experiencing an internet speed of 12Mbps given that the customer is served by Charter,

All speeds between 7Mbps and 15Mbps are equally likely.

This implies, the probability of experiencing a speed of 12Mbps given Charter is,

P(12Mbps/A) = 1 / (15Mbps - 7Mbps)

                     = 1 / 8

P(B|A'), the probability of experiencing an internet speed of 12Mbps given that the customer is served by Xfinity,

All speeds between 10Mbps and 20Mbps are equally likely.

This implies, the probability of experiencing a speed of 12Mbps given Xfinity is,

P(12Mbps|A') = 1 / (20Mbps - 10Mbps)

                     = 1 / 10

Now substitute all the values into Bayes' theorem,

P(A|B) = P(B|A) × P(A) / [P(B|A) × P(A) + P(B |A') × P(A')]

= (1/8) × 0.3 / [(1/8) × 0.3 + (1/10) × 0.7]

= 0.349

Therefore, the probability that the customer is served by Charter given that they are experiencing an internet speed of 12Mbps is 0.255, or about 34.9%.

Answer:

The table shows that the highest level of education achieved among the 450 adults surveyed by the National Society of Acupuncturists was a bachelor's degree or higher, with 240 respondents having achieved this level of education. The next highest level of education was a high school diploma or equivalent, with 120 respondents having achieved this level. There were also 60 respondents with some college education but no degree, and 10 respondents with a graduate degree.

Based on this information, it appears that there is a positive correlation between education level and the belief that acupuncture is a reasonable form of medicine. This could be due to a variety of factors, such as increased exposure to scientific and medical knowledge through education, a more open-minded and skeptical approach to healthcare, or a greater willingness to try alternative therapies. It is important to note, however, that correlation does not necessarily imply causation, and there may be other factors at play that are not captured by this data.

The percentage of saline solution in brand B is 3%. Then the correct option is B.

Let x be the percent of saline solution in brand B.

Since Danielle combined brands A and B to create a total of 18 gallons of 8% saline solution, we know that the total volume of saline solution in the combination is 18% of 6 gallons + x% of (18 - 6) gallons.

Thus, we can set up the equation:

0.18(6) + 0.01x(18 - 6) = 0.08(18)

Simplifying and solving for x, we get:

1.08 + 0.12x = 1.44

0.12x = 0.36

x = 3

Therefore, the percentage of saline solution in brand B is 3%.

Answer:165+12x=y

Step-by-step explanation:there is 3 $55 games and x12 dollars game so that the equation.

The solution of the differential equation that satisfies the given initial condition is -1/L = k[t㏑t - t + 1] + 1/4.

Given is the differential equation is given as:-

dL/dt = kL²㏑t with initial condition L(1) = -4,

Now separate the variable and its derivative,

dL/L² = k㏑t dt

Integrating,

∫dL/L² = k∫㏑t dt + c

(-1/L) = k[t㏑t - ∫t·1/t dt] + c

-1/L = k[t㏑t - t] + c

Now apply the initial condition L(1) = -4,  

1/4 = k(-1) + c

c = 1/7 + k

Therefore, the solution is =

Here, we know that Asymptomatic:

Any condition that a patient tests positive for but does not manifest any symptoms of is referred to in medicine as being asymptomatic. After a diagnosis, a medical illness may be deemed asymptomatic if no obvious symptoms emerge.

Absence of symptoms is referred to be asymptomatic. If your doctor says you are asymptomatic, this indicates you have a disease or condition but don't show any symptoms or outward indicators of being ill.

Instances of sickness that are symptom-free for all or part of the time are frequently referred to be asymptomatic. Pre-symptomatic, however, is a word sometimes used to describe patients that initially have no symptoms but later develop them.

The Vector R will be 4.8 units in the direction of East of South. Then the correct option is B.

Given that:

Vector C is 3.5 units West

Vector D is 3.3 units South

The quantity which has magnitude, and direction, and follows the law of vector addition is called a vector.

Vector R is equal to Vector D - Vector C. Then we have

Vector R = Vector D - Vector C

Vector R = 3.3 units South - 3.5 units West

Vector R = 3.3 units South + 3.5 units East

Using the system of equations, the number of adults and the number of children who were committed are 140 and 104 respectively.

Given that,

The admission fee at an amusement park is $1.50 for children and $4 for adults.

Let x be the number of adults and y be the number of children who were admitted.

On a certain day, 244 people entered the park, and the admission fees collected totaled 716.00 dollars.

We get a system of equations,

x + y = 244

4x + 1.5y = 716

From the first equation,

y = 244 - x

Substituting this to second equation,

4x + 1.5(244 - x) = 716

4x + 366 - 1.5x = 716

2.5x = 350

x = 140

y = 244 - x = 104

Hence the number of children equals 104 and the number of adults equals 140.
