Answer:
calculus, geometry, arithmetic among a few
Step-by-step explanation:
Mathematics is involved in winter Olympics in different aspects like arithmetic which helps in scores, measurements, quantities and motion of the sport like hockey, running.
Scoring in ice skating involves arithmetic operation when an individual element is assigned points and judged on performance level( triple axle is 3 points but overall performance and artistry is measured by the judges).
Another is Calculus which helps to understand the change in acceleration and velocities while each skaters start at zero then win, Lines in Geometry such as the finish/start/sight lines helps players with angles of reflection, measuring angles and angles of incidence.
Answer: 60°
Step-by-step explanation: this is because angles 1 and 3 are the same, so if line y is moved 5 degrees to the right (clockwise), then it expands angles 1 and 3, so you add 5° to the already known 55°. Hope I helped!
Answer:
0.025
Step-by-step explanation:
Given that the arrival time of a professor to her office is uniformly distributed in the interval between 8 and 9 A.M.
If the professor did not arrive till 8.20 he will arrive between 8.21 and 8.40
Hence probability for arriving after 8.20 is 1/40
Prob he arrives at exactly 8.21 is 1/60
To find the probability that professor will arrive in the next minute given that she has not arrived by 8: 20.
= Prob that the professor arrives at 8.21/Prob he has not arrived by 8.20
This is conditional probability and hence
=
