Hi! For the area of a parallelogram, we just need to multiply the base and the height. It may sound simple but the tricky part in this problem is determining which one is the height.
For a parallelogram, the height is defined as the measurement PERPENDICULAR to the base. Therefore, for this problem, we need to multiply 14 and 4.5 instead of 14 and 6.
ANSWER: B. 63 square meters.
Answer:
435 ft
Step-by-step explanation:
area of triangle:
A = (b x h) : 2
A = (15 x 4) : 2
A = 60 : 2
A = 30 ft
area of rectangle:
A = b x h
A = 25 x 15
A = 375 ft
area of the yard = area of the triangle + area of the triangle + area of the rectangle (Here, both triangles have the same area.)
area of the yard: 30 + 30 + 375 = 435 ft.
So, the area of the yard is 435 ft.
I hope this was helpful. :)

Answer:
a) The expected number of smokers in a random sample of 140 students from this university is 16.8 smokers.
b) No, it is unlikely that smoking habits and waking up early to go to the gym on Saturday are independent.
Step-by-step explanation:
To calculate the expected numbers of smokers in a sample with size n=140 and proportion p=12%, we use the expected value of the binomial distribution:
The expected number of smokers in a random sample of 140 students from this university is 16.8 smokers.
If we take a sample at the opening of the gym, the sample is not expected to be representative of the population of the students. Most of the students that go to the gym usually have healthy habits, so the proportions of smokers is expected to be lower than the average of the university population.
You also need to brake down this answer farther.
There are a lot of other step that will be in between but the answer will end up being.....
