It is lower then 20 so most likely C (15)
Answer:
y=4
Step-by-step explanation:
A) 1/6
B) 5/6
C) 1
D) 20
Explanation:
A) There is one 6 on a 6-sided die, out of 6 numbers.
B) There are 5 numbers that are not 6 on a 6 sided die, out of 6 numbers.
C) P( 6 or ~6) = P(6) + P(~6) = 1/6 + 5/6 = 6/6 = 1
D) 1/6(120) = 120/6 = 20
0.045 = 45/1000
Divide top and bottom by their greatest common factor.
It looks to me as though the greatest common factor of 45 and 1,000 is 5 .
Divide top and bottom by 5 and we have <u>9/200</u> . That's the simplest form.
We have equation:
t=20x+31
x is number of years after 1997.
To calculate number of laptops in 2005:
x=2005-1997
x=8
t=20*8+31
t=160+31
t=191
In year 2005 school had 191 laptops.
