Answer:
Yes, reflecting a shape across the x-axis and then rotating it 90° clockwise about the origin gives the same results as reflecting it across the y-axis followed by rotating it 90° counterclockwise about the origin. This means these two sequences of transformations are equivalent.

Answer:
Capital: 2 400
Tasa: 5% = 5/100 = 1/20
Tiempo: 4 años
A) Interés = capital*tasa*tiempo
Interés = 2400*(1/20)*4
Interés = 480 soles
B) Interés = Capital*((1 + tasa)^tiempo+1)
Interés = 2400*((1 + 1/20)^4 + 1)
Interés = 2400*((21/20)^4 + 1)
Interés = 2400*(194 481/160 000 + 1)
Interés = 2400*(354 481/160 000)
Interés = 5 317,215Step-by-step explanation:
Answer:
8.81% probability that the student answers exactly 4 questions correctly
Step-by-step explanation:
For each question, there are only two possible outcomes. Either he answers it correctly, or he does not. The probability of answering a question correctly is independent of other questions. So we use the binomial probability distribution 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.
In which 
is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
A multiple choice exam has ten questions.
This means that 
The probability of answering any question correctly is 0.20.
This means that 
What is the probability that the student answers exactly 4 questions correctly
This is P(X = 4).
8.81% probability that the student answers exactly 4 questions correctly
