Answer: The total distance Fiona covers in two laps of the race = 880 meters
Step-by-step explanation:
Given : Fiona races BMX around a circular dirt course.
The radius of the course is 70 meters.
Then , Circumference of circular dirt course = 
=
![[\text{Use }\pi=\dfrac{22}{7}]](https://tex.z-dn.net/?f=%5B%5Ctext%7BUse%20%7D%5Cpi%3D%5Cdfrac%7B22%7D%7B7%7D%5D)
Now , the total distance Fiona covers in two laps of the race = 2 x (Circumference of circular dirt course)
= 2 x (440 meters)
= 880 meters
Hence, the total distance Fiona covers in two laps of the race = 880 meters
<u>Answer:</u>
C (third figure from left)
<u>Step-by-step explanation:</u>
The spirals in the first, second, and fourth figures are all clockwise from the outer end, i.e., if you trace these three spirals with your finger from the outside to the inside, your finger will move clockwise.
However, if you did the same with the third figure, you would see that the spiral is anti-clockwise from the outside moving in.
Therefore, the third figure doesn't belong.
Answer:
In the present, Jeremiah would be 29 and Raymond, 37. As such, in 15 years, both of them would be 44 and 52 respectively, thus meaning their ages would equal 96.
Step-by-step explanation:
29 + 37 = 66
29 + 15 = 44
37 + 15 = 52
44 + 52 = 96
Answer:

And using the probability mass function we can find the individual probabilities:


And replacing we got:
![P(X\geq 2)=1 -[0.2044 +0.3590]= 0.4366](https://tex.z-dn.net/?f=%20P%28X%5Cgeq%202%29%3D1%20-%5B0.2044%20%2B0.3590%5D%3D%200.4366)
Then the probability that at least 2 disapprove of daily pot smoking is 0.4366
Step-by-step explanation:
Let X the random variable of interest "number of seniors who disapprove of daily smoking ", on this case we now that:

The probability mass function for the Binomial distribution is given as:

Where (nCx) means combinatory and it's given by this formula:

And we want to find this probability:

And using the probability mass function we can find the individual probabilities:


And replacing we got:
![P(X\geq 2)=1 -[0.2044 +0.3590]= 0.4366](https://tex.z-dn.net/?f=%20P%28X%5Cgeq%202%29%3D1%20-%5B0.2044%20%2B0.3590%5D%3D%200.4366)
Then the probability that at least 2 disapprove of daily pot smoking is 0.4366
