Step-by-step explanation:
You need to use the Pythagorean theorem:
L =
= 13,4 feet
Answer:
2
Step-by-step explanation:
7/3+3(2/3−1/3)^2
=7/3+6/9-3^2/9
=7/3+6/9-9/9
=7/3+2/3-3/3
=6/3
=2
No.
A scalene triangle is one with no sides equal.
An equilateral is one with the three sides equal.
So a scalene triangle can not be equilateral.
Answer:
L = 3.9
Step-by-step explanation:

L = 3.9
Answer:
The probability of the temperature exceeding 65 degrees Fahreneit but not needing a rolling blackout is 0.4- Hence, there is a 40% chance.
Step-by-step explanation:
Lets call F the event 'the temperature will exceed 85 degrees Fahrenheit' and B the event 'a blackout will be needed'.
We want P(F ∩ B^c), note that if F happens, there could be 2 disjoint possible events: B or B^c, hence
P(F) = P(F ∩ B) + P(F ∩ B^c)
Hence
P(F ∩ B^c) = P(F) - P(F ∩ B) = 0.6 - 0.2 = 0.4
