what variable is the most important in the human body? length,
viscosity or diameter
Answers
The most important variable in the human body is likely dependent on the specific context and system being considered.
Length, viscosity, and diameter are all important variables in the human body, but it is difficult to say which one is the most important as each plays a different role in different bodily systems.
Length, for example, is important in skeletal muscle physiology, where it determines the force and velocity of muscle contractions. Viscosity is important in the circulatory system, where it affects blood flow and the ability of the blood to transport oxygen and other nutrients. Diameter is also important in the circulatory system, as it determines the resistance to blood flow and the distribution of blood to different organs and tissues.
Therefore, the most important variable in the human body is likely dependent on the specific context and system being considered.

D) x = -2,6
Answers
The domain restrictions for (f/g)(x) are (c) x = 0, 6
How to determine the domain restrictions for (f/g)(x)?From the question, we have the following parameters that can be used in our computation:
f(x) = x² - 5x - 6
g(x) = x² - 6x
The composite function (f/g)(x) is calculated as
(f/g)(x) = f(x)/g(x)
substitute the known values in the above equation, so, we have the following representation
(f/g)(x) = (x² - 5x - 6 )/(x² - 6x)
For the domain restriction, we have
x² - 6x = 0
When solved, we have
x = 6 or x = 0
Hence, the domain restrictions for (f/g)(x) are (c) x = 0, 6

The probability of a randomly selected adult in one country being infected with a certain virus is 0.005. In tests for the virus, blood samples from 20 people are combined. What is the probability that the combined sample tests positive for the virus? Is it unlikely for such a combined sample to test positive? Note that the combined sample tests positive if at least one person has the virus.The probability that the combined sample will test positive is
Answers
Answer:
0.0954 = 9.54% probability that the combined sample tests positive for the virus. This probability is higher than 5%, and thus, it is not unlikely for such a combined sample to test positive.
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they test positive, or they do not. The probability of a person testing positive is independent of any other person, which means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)
In which \(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.
\(C_{n,x} = \frac{n!}{x!(n-x)!}\)
And p is the probability of X happening.
The probability of a randomly selected adult in one country being infected with a certain virus is 0.005.
This means that \(p = 0.005\)
Samples from 20 people
This means that \(n = 20\)
What is the probability that the combined sample tests positive for the virus? Is it unlikely for such a combined sample to test positive?
Probability of at least one positive test, which is:
\(P(X geq 1) = 1 - P(X = 0)\)
In which
\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)
\(P(X = 0) = C_{20,0}.(0.005)^{0}.(0.995)^{20} = 0.9046\)
Then
\(P(X geq 1) = 1 - P(X = 0) = 1 - 0.9046 = 0.0954\)
0.0954 = 9.54% probability that the combined sample tests positive for the virus. This probability is higher than 5%, and thus, it is not unlikely for such a combined sample to test positive.

First, you have to figure out how many words he types in one minute. Then, have to multiply by the number of minutes. So,
Number of words per minute:
742 = Total number of words in 14 min
14 = time given
742/14 = 53 words per minute

What is a function?We know that a function has to do with a mathematical rule that is used for the establishment of a fact. We have from the question that the function that models the car is; V = 2000000(1.025)^n
Let us recall that n has to do with the number of years.
a) In four years, the value of the car would be;
V = 2000000(1.025)^4
V = 2,207,626
b) The growth rate percent of the function can be obtained as;
1.025 * 100 = 102.5 %
c) To obtain the year in which the value of the car would reach 2624173.32, we have;
2624173.32 = 2000000(1.025)^n
2624173.32/2000000 = (1.025)^n
1.312 = (1.025)^n
ln1.312 = n ln (1.025)
n = ln1.312 /ln (1.025)
n = 0.272/0.025

Which function has the same range as \(f(x)= - 2\sqrt{x} =-3 + 8\\\)
Answers
Both g(x) = 5 - x² and h(x) = \(5 - e^(6-^x^)\)have the same range as f(x) = -2√(x) - 3 + 8, which is (-∞, 5].
To determine which function has the same range as f(x) = -2√(x) - 3 + 8, we need to first find the range of f(x).
The square root function √(x) takes non-negative values as input and gives non-negative outputs, so the expression -2√(x) will always be non-positive. Therefore, the range of f(x) will be all real numbers less than or equal to -3 + 8, which is 5.
In other words, the range of f(x) is (-∞, 5].
So, we need to find a function whose range is also (-∞, 5]. One possible function is g(x) = 5 - x². We can see that when x is zero, g(x) is at its maximum value of 5, and as we increase or decrease x, g(x) will decrease, eventually approaching negative infinity.
Another possible function is h(x) = 5 - e^(-x). When x is negative infinity, e^(-x) is approaching positive infinity, so h(x) is approaching 0. As we increase x, e^(-x) is approaching zero, so h(x) is approaching 5.

Domain is the set of all first numbers of the ordered pairs in a relation and range is the set of second numbers of the ordered pair in relation.
The domain is the set of independent values, meaning the set of x-coordinates of the ordered pair as x is an independent variable.
The range is set of dependent values, meaning the set of y-coordinates of the ordered pair as y is an independent variable.

Decide whether the rates are equivalent. Maria saves $50 in 4 months.
Ralph saves $60 in 5 months
Answers
Answer:
The rates are not equivalent since Maria saves $0.50 more per month than Ralph.
Step-by-step explanation:
We can determine if two rates are equivalent by comparing the rates at which they save per month.
Maria's savings per month:
Both 50 and 4 can be divided by 2, which gives us 25/2. As a regular number, this becomes 12.5/1 which means Maria saves $12.5 per month.
Ralph's savings per month:
Both 60 and 5 can be divided by 5, which gives us 12. Thus, Ralph saves $12 per month.
Thus, the rates are not equivalent as Maria saves $0.50 more per month than Ralph.

Para resolver esto, primero debemos analizar la información que se nos da:
El 18% de los árboles son aguacates.Hay 45 aguacates.Si definimos N como el número total de arboles, sabemos que el 18% de N es igual que 45.
Entonces podemos escribir:
(18%/100%)*N = 45
0.18*N = 45
Ahora podemos resolver esto para N:
N = 45/0.18 = 250
