Answer:
28
Step-by-step explanation:
The binomial coefficient is calculated as:
It means that there are nCx ways to select x elements from a group of n elements.
So, If the researcher wants to determine the probability that 6 out of the next 8 individuals in his community are in favor of the president, we can replace n by 8 and x by 6 and calculated the binomial coefficient as:

<span>if 8 machine can do it in 5 days then 40 machines can do it in 1 day (8x5=40 machines worth of work)
for the first 2 days you have 4 machines only (2x4=8 machines worth of work)
leaving (40-8) 32 machines worth of work. From day 3 you have all 8 machines working. 32/8 = 4 more days
2 days (4 machines) and another 4 days (with 8 machines) = 6days to make all the bottles</span><span>

Answer:
There are 32 dogs and 72 animals in total.
Step-by-step explanation:
In order to find the amount of dogs, you need to set up an equation to solve for the missing variable. Let 'c' be the amount of cats and 'd' be the amount of dogs. We know that there are 40 cats, so c = 40. We also know that there are 25% more cats than dogs, so we can form an equation to express this difference: 1.25d = c, indicating that the number of cats is equal to the total number of dogs, plus an additional 25%. Since we know c = 40, we can set our second equation equal to 40: 1.25d = 40. Using inverse operations, we divide both sides by 1.25 to get d = 32. So, d + c, or 32 + 40 = 72 total animals.
