Answer:1,0.5, or 0 it depends
Explanation:
The probability that one event occurred depends on the total of random event, being 1 the most of the probabilities
If the two marbles are blue the probability to select a marble blue is 1
If one of the marbles is blue and the other marble is of any color the probability to select the blue marbles is:
P=1 - 1/2=1/2
Being 1/2 or 0.5 the answer
If any of the marbles are blue then the probabilities are 0
You find the slope of the line by using the formula 
where x1 and y1 is the first point, and x2 and y2 are the second point.
Answer:
Arc DE = 90°
m<GAB = 82°
Arc DC = 49°
Step-by-step explanation:
Given:
m<EAF = 74°
m<EAD = right angle = 90°
Arc BG = 82°
Required:
Arc DE,
<GAB, and
Arc DC
Solution:
Recall that the central angle measure = the intercepted arc measure.
Therefore:
✔️Arc DE = m<EAD
Arc DE = 90° (Substitution)
✔️m<GAB = arc BG
m<GAB = 82° (Substitution)
✔️Arc DC = m<CAD
Find m<CAD
m<CAD = ½(180 - m<GAB)
m<CAD = ½(180 - 82)
m<CAD = 49°
Arc DC = m<CAD
Arc DC = 49°
Answer:
3
Step-by-step explanation:
Again, anything to the 0th power is equal to 1.
The 0th power is attached to the b, so this means that b = 1. Multiply 9 and (1) together to get 9.
Now you can subtract 9 from 12 to get 3 as your final answer.
