The probability of the black sock is 6/26 for the white is 16/26 and for the brown is 4/26
Answer:
f(- 2) = 23
Step-by-step explanation:
substitute x = - 2 into f(x) and evaluate
f(- 2) = 3(- 2)² - (- 2) + 7 = 12 + 4 + 7 = 23
Step-by-step explanation:
hey there....I only knew the last question
Answer:
-71i + 12j +47k
Step-by-step explanation:
The notation of the distance moved
In x-direction = -71
Considering the left side as the positive y- direction;
In y-direction= 12
In z-direction = 47
Therefore, the vector notation is
Displacement r = -71i + 12j + 47k
A= 35° because 180°-80°-65°= 35°
b=50° because 180°-95°-35°= 50°
c=85° because 180°-95°= 85°
d=30° because 180°-65°-85°= 30°
For these you just have to remember that the sum of the angles of a triangle is 180°, and the same for a straight line.
