The two numbers are very near 7200 and 300. The sum of those is a good estimate of your sum:
... 7200 + 300 = 7500
_____
If you're taught methods of addition that include "make a ten" or "make a hundred", you know you can "borrow" a 1 from 7203 (making it 7202) and loan that 1 to 299 to make it 300. Now, you know your sum is exactly 7202+300 = 7502, with no estimation necessary.
The possibilities of an even number are 2, 4, 6, 8, 10, 12, 14, and 16 .
The possibilities of an odd prime are 3, 5, 7, 11, and 13.
8 even numbers + 5 odd primes = 13 possibilities of success
out of 16 total possible outcomes.
Probability of success = 13/16 = 0.8125 = 81.25% .
Rounded to the nearest thousandth, it's 0.813 .
Answer:
5
Step-by-step explanation:
35 in total, sliced into 7 equal parts (1 per week).
so, each weekly part is therefore 35/7 = 5.
Hi there!
We can find the zeros of a function by solving f(x) = 0. We find the following:

Add 300 to both sides.

Divide by 3.

Take the root and minus root of both sides.

Therefore, the zeros are
x = 10 and x = -10.
