Answer:
0.8
Step-by-step explanation:
The question here says that In a class of 30 students, 18 are men, 6 are earning a B, and no men are earning a B. If a student is randomly selected from the class, find the probability that the student is a man or earning a B.
Since the question says that 18 out of 30 students are men,6 out of the remaining people earn a "B" and non of the 18 men earn a "B".
The probability of picking a man or a person that earns a "B" is
18/30 (since there are 18 men out of the 30 students)
And 6/30(since there are 6 people that earn a "b")
The probability of picking a man or a "b" earner is
18/30 + 6/30
= 24/30 or 0.8
Answer:
![y=x^2+5x+20\\ \\ y=8x^2+35](https://tex.z-dn.net/?f=y%3Dx%5E2%2B5x%2B20%5C%5C%20%5C%5C%20y%3D8x%5E2%2B35)
Explanation:
The <em>end behavior</em> of a <em>rational function</em> is the limit of the function as x approaches negative infinity and infinity.
Note that the the values of even functions are the same for ± x. That implies that their limits for ± ∞ are equal.
The limits of the quadratic function of general form
as x approaches negative infinity or infinity, when
is positive, are infinity.
That is because as the absolute value of x gets bigger y becomes bigger too.
In mathematical symbols, that is:
![\lim_{x \to -\infty}3x^2=\infty\\ \\ \lim_{x \to \infty}3x^2=\infty](https://tex.z-dn.net/?f=%5Clim_%7Bx%20%5Cto%20-%5Cinfty%7D3x%5E2%3D%5Cinfty%5C%5C%20%5C%5C%20%5Clim_%7Bx%20%5Cto%20%5Cinfty%7D3x%5E2%3D%5Cinfty)
Hence, the graphs of any quadratic function with positive coefficient of the quadratic term will have the same end behavior as the graph of y = 3x².
Two examples are:
![y=x^2+5x+20\\ \\ y=8x^2+35](https://tex.z-dn.net/?f=y%3Dx%5E2%2B5x%2B20%5C%5C%20%5C%5C%20y%3D8x%5E2%2B35)
Answer:
The question may be incomplete.
I guess the answer is as follows:
we are given the function adn we can see that when t is increased, P(t) is decreasing because of the negative sign. This means the value of the population which is the original of 64 billion will have to decrease.The answer that makes sense here is D. D. In 1990, there were 5.33 billion people.
Multiply it by 16/5, or the reciprocal
