Answer:
120 ways
Step-by-step explanation:
To solve the question above, we use combination formula:
Where ;
nCr = n! / (n-r)! r!
10C7 = 10! / (10 - 7)! 7!
10C7 = 10! / 3! 7!
10C7 = (10 * 9 * 8) / 3 * 2 * 1
10C7 = 720 / 6
= 120 ways
estimate the product.23.8*349
The range is 7. Here's how i found it. First i ordered it from least to greatest. Like this:
2,3,4,8,9
Then i subtract the lowest number from the highest number:
9-2=7
So the answer is 7. I hope i helped!
