Answer:
1) 0.1667
2) 0.8333
3) 1
Step-by-step explanation:
Let A be the event that 3 is observed on the first trial.
Let B be the event that at least two trials are required to observe a 3
a) A six-sided die has 6 possible outcomes of 1,2,3,4,5,6
3 is one of the six possible outcomes
P(A) = no of favourable outcomes /no of possible outcomes
P(A) = 1/6 = 0.1667
b) The event of requiring at least two trials to observe a 3 is the event of not observing a 3 on the first trial.
P(B) = P(A')
P(A')= 1 - P(A)
P(B) = 1 - 1/6
= 5/6 = 0.8333
c) P(AnB) = P(A) + P(B)
= 1/6 + 5/6
= 6/6 = 1
Distributive property. look. 15f-40g+2g then -40+2 is -38 so 15f-38 is your answer
Perpendicular means opposite and reciprocal (in reference to the slope).
The opposite of 1/2 is -1/2. The reciprocal of -1/2 is -2.
Now we know the slope we can plug the point they gave us into the X and Y positions to solve for b (in the point (2, 3) there is a X - Value (2) and a Y-value (3)
y= -2x+b
3= -2(2)+b
3= -4+b
1=b
Now we plug b and the slope in the generic y=mx+b equation:
y= -2x+1
Answer:
b) b
e) c
f) 2b
Step-by-step explanation:
you look for numbers that can divide them all at once
