Answer:
85%
Step-by-step explanation:
If 30 of them have their own lawn service then that means 170 of them do not have their own lawn service.
Seeing as there are 200 houses in total, the fraction of people who don't have lawn service is 170/200. This is equal to 0.85 or 85%.
I think it is c, because the probability is the littlest thing and you add most of it, you are welcome my boy
Answer:
455ways
Step-by-step explanation:
This is expressed as 15 C 3 ( C- combination)
The concept of combination is used when we talk about selection.
Now we are selecting 3 from a sample of 15
15 C 3 = 15! / (15-3)! 3! = 15 ×14×13×12!/12!×3×2
= 5 × 7 × 13 = 455ways
Answer:
The least common multiple would be 140.
Step-by-step explanation:
The least common multiple is known to be a multiple that is the lowest value that satisfies being a multiple with the other factors given.
The least common multiple was 140 as it was the lowest value that satisfied being a multiple of 14, 10, AND, 20,
14 * 10 = 140
20 * 7 = 140
10 * 14 = 140
First,
149,500 * .10 = 14,950
149,500 - 14,950 = 134,550
then,
134,550 * .05 = 6727.50
134,550 - 6727 = 127,822.55
127,822.50 * .04 = 5112.90
trade discount = 14950 + 6727.50 + 5112.90
26790.40
hope this help
