Answer:
8
Step-by-step explanation:
62 divided by 8 is 7.75
you can't cut people so round it up and you get 8
Answer:
y - 6 = -3(x - 4)
y - 6 = -3x + 12
y = -3x + 18
Standard form: 3x + y = 18 (c)
Step-by-step explanation:
Yes because the range values don't repeat
Answer:
Mean is 19.43
Standard deviation is 2.5322
Step-by-step explanation:
For each student who graduated from high school in 2012, there are only two possible outcomes. Either they have enrolled in college, or they have not. The probability of a student having enrolled in college is independent of other students. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
67% of students who graduated from high school in 2012 enrolled in college.
This means that
Sample of 29 high school graduates
This means that
Mean
Standard deviation
9.75 x 7.2 = 70.2
Swimming Pool Area: 70.2
The Park Area: 70.2 x 1.5 = 105.3
Total Area of both Swimming Pool & Park area: 70.2 + 105.3 = 175.5
Final Answer: 175.5
