Answer:
c
1,400
Step-by-step explanation:
We take the sample proportion of skunks and estimate for the entire population.
Sample:
140 skunks out of 230 + 140 + 120 = 490 animals.
140/490 = 0.28571428571
If a random sample of 5,000 animals are trapped in the city, how many skunks would be estimated to be included?
0.28571428571 out of 5000. So
0.28571428571*5000 = 1429
Close to 1400, which means that the answer is given by option C.
Answer:
360 hours
Step-by-step explanation:
To convert 15 days into hours, we need to find hours in a day. There are 24 hours in a day.
We can take 15 days/1 and multiply it by 24 hours/1 day, and we can cancel out the day units.
Then, we multiply 15 by 24 to get 360 hours.
Hope this helps

since she has half a gallon and needs to split that between 18 dishes equally this means that 1/2÷18=1/36. each dish will have 1/36 of a gallon of salsa
<span>This is a matter of knowing the formulas involving the binomial distribution:
Mean = n*p = 125*0.46 = 57.5
Variance = n*p*(1-p) = 125*0.46*(1-0.46) = 125*0.46*0.54 = 31.05
Standard Deviation = sqrt(Variance) = sqrt(31.05) = 5.572252686</span>
