Answer: Choice C) Multiplication property of inequality

The rule basically says that if you start with a < b and you multiply both sides by some positive number c, then a*c < b*c. The sign doesn't flip if you multiply both sides by a positive number.
The sign will flip if c is negative. So we'll go from a < b to a*c > b*c if c is negative.

Example 1:
1 < 5
-2 > -10 ... multiplied both sides by -2; sign flips

Example 2: 
3 < 7
9 < 21 ... multiplied both sides by 3; sign does not flip

Similar rules apply to a > b, a \le b and a \ge b

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.

I don't understand this question?...
olganol [36]

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!

The arrival time of a professor to her office is uniformly distributed in the interval between 8 and 9 A.M. Find the probability
NeTakaya

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

= P(professor arrives at 8.21)/P(professor arrives after 8.20)\\= \frac{\frac{1}{60} }{\frac{40}{60} } \\=\frac{1}{40} \\=0.025
