Hello!
We are asked to find the number of lines the choir has to learn in time for a concert.
We're given that the concert is in 7 weeks, but they learn new lines each day, so we have to convert it to days. We know that there is 7 days in a week, we would multiply 7 weeks by 7 days, which is 49 days.
Now, we would take the total number of lines, which is 3016, and divide that by 49 days.
3016 lines / 49 days ≈ 61.55 lines/day
Since this is a real-world situation, we should round our answer is to nearest whole number, which would be 62 lines/day.
Therefore, Ester's choir needs to learn about 62 lines per day in time for the concert.
Answer:
A. y = sine (x + 90 degrees)
Step-by-step explanation:
- y = cosine(x) is a curve that crosses the y-axis at y = 1 and completes one cycle at 360 degrees.
- sine(x) have the same curve than cosine(x), but translated 90° to the right respect cosine(x)
- f(x + c) translates f(x) horizontally c units to the left.
- Then, sine(x + 90) is equivalent to cosine(x)
The probability that both the chosen students are sophomores is 6/20 or 3/10 simplified.
the expresión that represents the probability that both students have chosen are sophomore is (6c1) (5c1) /(20c2)
Now find equation of the graph. It passes through the point (2,3), and intersects y-axis at -2.
