The correct option is C) 210.
Step-by-step explanation:
Consider the provided information.
The analyst has narrowed down the list of potential stocks to 7. She choose and rank her top 3 picks.
Since the order matter so we will use permutation.
The formula for permutation is:
Substitute n=7 and r=3 in above formula.
Hence, the correct option is C) 210.
Answer:
0
Step-by-step explanation:
1/3 m -1 -1/2 n
Let m =21 and n =12
1/3 (21) - 1 - 1/2 (12)
Multiply
7 - 1 - 6
Subtract
6-6
0
For questions 5-7, you see how there's corners in which you can draw a line through? For example number 6 you can at up 10yd+8yd which would give you 18yd. After that, split that. by 6yd because of the 11yd on the side. Sorry if I don't make much sense Good luck
Answer: 29/30
Step-by-step explanation: To add these two fractions together, we start by finding their common denominator.
The common denominator for 15 and 10 is 30 so we multiply the top and bottom of our first fraction by 2 to get 8/30 and we multiply the top and bottom of our second fraction by 3 to get 21/30.
Now we are adding like fractions. To add like fractions, we simply add across the numerators.
8/30 + 21/30 = 29/30
Therefore, 4/15 + 7/10 = 29/30.
The largest number that divides evenly into both 42 and 70 is 7.
