Answer:
Step-by-step explanation:
Urn U1: 3 red and 2 yellow marbles, in total 5 marbles.
The probability to select red marble is 
Urn U2: 3 red and 7 yellow marbles, in total 10 marbles.
The probability to select red marble is 
Urn U1: 1 red and 4 yellow marbles, in total 5 marbles.
The probability to select red marble is 
The probability to choose each urn is the same and is equal to 
Thus, the probability that the marble is red is
The vector written in its generic form is given by:
v = lvl cos theta ° i + lvl without theta ° j
Where.
lvl: magnitude of the vector
theta: angle of the vector with respect to the x axis.
For this case we have the following vector:
v = 3 cos 123 ° i + 3 without 123 ° j
Where,
lvl = 3
theta = 123 °
Answer:
The magnitude and direction angle for the vector v is:
D. 3, 123 °
Answer:
x = -8
Step-by-step explanation:
x- (-10) = 2
Subtracting a negative is like adding
x+10 =2
Subtract 10 from each side
x+10-10 = 2-10
x = -8
Answer:
the third answer is right
Step-by-step explanation:
its a rhombus because the 4 sides are of equal length and the opposite sides are parallel but there are no right angles.
Answer:
56 degrees
Step-by-step explanation:
i can't really explain but...
(96 - x)/2 = 20
48 = 20 + x/2
28 = x/s
x = 56 degrees
