Answer:
No solution.
Step-by-step explanation:
8x - 4 = 2(4x - 4)
8x - 4 = 8x - 8
-4 = -8
-4 ≠ -8
To calculate this probability we must take into account that there is the same probability that any of the 3 urns is chosen.
This probability is:
P (U1) = P (U2) = P (U3) = 1/3
Urn 1 contains 7 black and 3 red marbles
Urn 2 contains 2 black and 8 marbles network
Urn 3 contains 5 black marbles and 5 red marbles.
The probability of obtaining a black marble in Urn 1 is 7/10.
The probability of obtaining a black marble in Urn 2 is 2/10
The probability of obtaining a black marble in Urn 3 is 5/10.
Then we look for the probability of obtaining a black marble from urn 1 or a black marble from urn 2 or a black marble from urn 3. This is:
P (U1yB) + P (U2yB) + P (U3yB)
So:
(1/3) * (7/10) + (1/3) * (2/10) + (1/3) * (5/10) = 0,2333 + 0,0667 + 0,1667 = 0, 4667.
The probability that it is a black marble is 46.67%
There are 4 coordinate places from (-6, 2)
But from the choices.. It's
B. (-6, -3)

Answer:
The number 0.507 is a statistic parameter and population proportion as it states the proportion since the beginning (historically).
Step-by-step explanation:
If you calculate it and it gives you stats then that makes it a statistic parameter, you have sample of 45 newborns and you multiply with 0.40 (out of hundred) you get 18 boys which just the sample proportion of the set given.
If you multiply it with 0.507, it just gives about 22.81500 which just estimates that for every set of 45 babies you would get about 22 boys average.
Brandon's backpack weighs = 3140 grams.
We know, 1000 grams in a kilogram.
Therefore, 3140 grams = 3000 grams + 140 grams = 3 kilogram 140 grams.
Brandon weighs(without backpack) = 22 kg 610 grams more than his backpack.
More than pharse represents addition.
22 kg 610 grams more than backpack weighs = 22 kg 610 grams + 3 Kg 140 = 25 Kg 750 grams.
Therefore, Brandon weighs(without backpack) = 25 Kg 750 grams.
Total weight of Brandon weighs and backpack weighs = Brandon weighs(without backpack) + backpack weighs.
= 25 Kg 750 grams + 3 Kg 140 grams
= 28 Kg 890 grams.
Therefore, Brandon got 28 Kg 890 grams on a scale when wearing his backpack.
