Answer:
a)- Given that a student is a 10th grader, there is a 14% chance he or she has a job.
Step-by-step explanation:
Option (a) is correct here because Relative frequency means the probability of occurrence or number of time-specific event occurs to the total event.
Option (b) is not correct because We already know that student is in 10th or 11th grade, after that we get to know about 14% chance.
Option (c) & (d) are clearly not possible.

the last is the answer
Answer:
98.83
Step-by-step explanation:
Since 37° is 37/360th of the full circle, the area of the size of pie will be 37/360th of the full area. The radius is d / 2 = 17.5 so the area is:
37/360 * πr²
= 37/360 * 3.14 * 17.5²
= 98.83
Answer:
<em>3 hours</em>
Step-by-step explanation:
Given that:
Average speed of Willie = 40 km/h
After 2 hours, Gabriella traveled in opposite direction at an speed of 70 km/h.
After some time, they are 410 km apart.
To find:
Number of hours = ?
Solution:
For the first two hours, Willie traveled alone.
Formula for distance:

Distance traveled in two hours by Willie = 
Now, they both travel in opposite directions.
So the relative speed is = 40 + 70 = 110 km/h
The distance traveled by them = 410 - 80 = 330 km

Therefore, the time taken is <em>3 hours.</em>
