There are 92 students in a chemistry class. The instructor must choose two students at random. Students in a Chemistry Class Aca
Sergio039 [100]

Answer:

0.0108 = 1.08% probability that a sophomore non-Chemistry major and then a junior non-Chemistry major are chosen at random.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Probability that a sophomore non-Chemistry major

Out of 92 students, 9 are non-chemistry major sophomores. So

P(A) = \frac{9}{92}

Then a junior non-Chemistry major are chosen at random.

Now, there are 91 students(1 has been chosen), of which 10 are non-chemistry major juniors. So

P(B) = \frac{10}{91}

What is the probability that a sophomore non-Chemistry major and then a junior non-Chemistry major are chosen at random

P = P(A)*P(B) = \frac{9}{92}*\frac{10}{91} = \frac{9*10}{92*91} = 0.0108

0.0108 = 1.08% probability that a sophomore non-Chemistry major and then a junior non-Chemistry major are chosen at random.

When you multiply a function by -1, what is the effect on its graph?
nataly862011 [7]

C.


If you multiply a function by -1, you are inverting its sign. It means that you have the parent function f(x), and the child function -f(x).


This means that, if you choose the same input x, it will be mapped once to f(x), and once to -f(x).


So, if you draw the two graphs, you will associate two opposite y values to the same x value.


This kind of transformation, (x,y) \to (x,-y) is exactly a reflection with respect to the x axis.
