I think b because all the other lines are the same length and b lines aren’t
Answer:
A.) Y= 8
B.) X= 9
Step-by-step explanation:
I noticed that the equation is x4 because 4x4= 16 and 5x4= 20.
So, I multiplied 4x2 to get 8 and divided 36/4 to get 9.
Answer:
A) -56
Step-by-step explanation:
B) First, you have to ignore the plus sign, and recognize that the second negative number means you are subtracting that number.

Answer:
0.362
Step-by-step explanation:
When drawing randomly from the 1st and 2nd urn, 4 case scenarios may happen:
- Red ball is drawn from the 1st urn with a probability of 9/10, red ball is drawn from the 2st urn with a probability of 1/6. The probability of this case to happen is (9/10)*(1/6) = 9/60 = 3/20 or 0.15. The probability that a ball drawn randomly from the third urn is blue given this scenario is (1 blue + 5 blue)/(8 red + 1 blue + 5 blue) = 6/14 = 3/7.
- Red ball is drawn from the 1st urn with a probability of 9/10, blue ball is drawn from the 2nd urn with a probability of 5/6. The probability of this event to happen is (9/10)*(5/6) = 45/60 = 3/4 or 0.75. The probability that a ball drawn randomly from the third urn is blue given this scenario is (1 blue + 4 blue)/(8 red + 1 blue + 1 red + 4 blue) = 5/14
- Blue ball is drawn from the 1st urn with a probability of 1/10, blue ball is drawn from the 2nd urn with a probability of 5/6. The probability of this event to happen is (1/10)*(5/6) = 5/60 = 1/12. The probability that a ball drawn randomly from the third urn is blue given this scenario is (4 blue)/(9 red + 1 red + 4 blue) = 4/14 = 2/7
- Blue ball is drawn from the 1st urn with a probability of 1/10, red ball is drawn from the 2st urn with a probability of 1/6. The probability of this event to happen is (1/10)*(1/6) = 1/60. The probability that a ball drawn randomly from the third urn is blue given this scenario is (5 blue)/(9 red + 5 blue) = 5/14.
Overall, the total probability that a ball drawn randomly from the third urn is blue is the sum of product of each scenario to happen with their respective given probability
P = 0.15(3/7) + 0.75(5/14) + (1/12)*(2/7) + (1/60)*(5/14) = 0.362
Answer:
The answer to your question is: # of times = 60.7
Step-by-step explanation:
data
7.4 billion people
each person occupied 13 inches
Earth circumference = 25000 miles
length of the lines = 13 in x 7.4 billion people
= 13 x 7 400 000 000
= 9.62 x 10 ¹⁰ in
Convert in to miles
1 mile --------------- 63360 in
x mi --------------- 9.62 x 10 ¹⁰ in
x = 1518308.1 mi
Now divide, the line of people by the circumference
# of times = 1518308.1 mi / 25000 mi = 60.7
