A pythagorean theorem must satisfy a² + b² = c²
16² + 20² = 25²
256 + 400 = 625
656 ≠ 625 so no, the set 16, 20, 25 does not represent a pythagorean triple
Kenilworth = 9
Total = 40
Divide 9 by 40 to get the probability
9 ÷ 40 = 9/40
Your answer is 9/40 (22.5%)
Hope this helps :)
Answer:
-1 degree
Step-by-step explanation:
1.) Subtract 19 from 14.
14 - 19 = -5
2.) Add 4 to -5.
-5 + 4 = -1
Final temperature: -1 degree
Answer:
D) 7/8
Step-by-step explanation:
The probability that there is at least one student at both Saturday's and Sunday's events is the inverse of the probability of having all students selecting either Saturday OR Sunday.
Since the probability of a student selecting Saturday is 0.5, the probability of all 4 students selecting that day is
0.5 * 0.5 * 0.5 * 0.5 = 1/16
Then the probability of having all students selecting either Saturday OR Sunday is twice that, which is 2/16, or 1/8
Therefore the probability that there is at least one student at both Saturday's and Sunday's events is 1 - 1/8 = 8/8 - 1/8 = 7/8
