Answer:
Yes, it will be enough.
Step-by-step explanation:
In this problem, we must check if the number of all possible variations of the five-digit ID code will be greater than the expected 75,000 students.
If all the numeric symbols from 0 to 9 will be used in the ID, there are ten possible values for each of the five digits. Therefore, the total number of possibilities (N) can be determined as follows:
![N=10*10*10*10*10\\N=100,000\\](https://tex.z-dn.net/?f=N%3D10%2A10%2A10%2A10%2A10%5C%5CN%3D100%2C000%5C%5C)
Since the total number of possible five-digit IDs is bigger than the expected number of students, this system will be enough.
Answer:
30×pi ft
Step-by-step explanation:
ST is the diameter.
the formula for the circumference of a circle is
C = 2×pi×r
r = radius = diameter / 2
so,
C = 2×pi×30/2 = pi×30
therefore, the first answer option is correct.
Answer:c
Step-by-step explanation of the
(-10)/(-20)
-1/(-2)
Negative sign result in positive result, so
1/2; c
Answer:
The candidate should get 5829 votes.
Step-by-step explanation:
This is a proportion question. The ratio should hold for both the pole and the actual vote.
Equation
x /9570 = 67/110 Multiply both sides by 9570
x = 67 * 9570 / 110 Multiply the two numerators.
x = 641190 / 110 Divide by 110
x = 5829
