Answer:
Step-by-step explanation:
1) (-13)* .......(-13) for 35 times = (-13)³⁵
2) (2/3) * ...... * (2/3) for 4 times = (2/3)⁴
3)(-3.1)* ......(-3.1) for 4 times = (-3.1)⁴ = 92.2531
Short answer: 3240 handshakes.
Remark
If you watch hockey, you've actually seen this happen. After the game, the winning team will stay on the ice usually on center ice. As you look at them, the man on your right will go down the line and rough up or shake hands or say something to each of his teammates on the line. Then he goes into the dressing room. So he has talked to n - 1 people. The next person going down the line will talk to n - 2 people. and so on all the way down the line.
Formula
Sum = (n + 1)*n/2 is what the formula is.
Givens
n = 80
Sub and Solve
Sum = (80 + 1)*80 / 2
Sum = 81 * 40
Sum = 3240 handshakes.<<<<< Answer
The fifth period class has a greater fraction of students that like to bowl.
Any number in the form of p/q where p and q are integers and q is not equal to 0 is a rational number. Examples of rational numbers are 1/2, -3/4, 0.3, or 3/10.
Here we have,
In second period, 37.5% students like to bowl
∴, 37.5% = 37.5/100
= 375/1000
= 0.375 students like to bowl in second period
And in fifth period, 12 students out of 29 like to bowl
Therefore, 12/29 = 0.413 students like to bowl in fifth period
Hence, on comparison
0.375 < 0.413
= 375/1000 < 12/29
Thus, fifth period class has a greater fraction of student that like to bowl as compared to second period class.

Answer:
First choice: 0, pi
Step-by-step explanation:
I am assuming the equation is
(the =0 part is missing in the original problem)
So, the full solution for q is three values: 0, pi, 2pi. This matches the first choice (which is not complete, but that is ok)
