The minimum number of rows is 1: if A is sorted in descending order, every next students will arrive in a row where everyone is taller than him, and no new rows will be created.
For example, consider
A = [190, 175, 170, 165, 150]
The first students creates the first row.
The second student is 175cm tall. In the first row everyone is taller than him (there's only the 190cm student), so he'll stand in this row.
The third student, 170cm, will find the row filled by the students who are 190 and 175cm tall. So, everyone is taller than him and he'll stand in that row as well.
You keep going with the other students, and you'll see that no one will form a new row.
Answer:
3cos(x)
Step-by-step explanation:
use cot(t) = 1/tan(t), transform the expression:
3tan(x)cos(x)x1/tan(x)
reduce the expression with tan(x):
3cos(x)
Answer:
Step-by-step explanation:
To determine how much are you making on your investment, we will apply the simple interest formula. It is expressed as
I = PRT/100
Where
P = principal or amount invested,
R = interest rate
T = time
From the information given,
P = $1,500
T = 1 year
R = 8.5
I =( 1500×8.5×1)/100
I = $127.5
For a year you owe $1,600 on a credit card. You pay 19% interest a year on this credit card debt.
Interest paid = (1600×19×1)/100 = $304
The loss is 304 - 127.5 = - $176.5
I would say 50/50 chance because it can go ether ways one can go heads the others can go tails
