The probability that exactly 4 of the selected adults believe in reincarnation is 5.184%, and the probability that all of the selected adults believe in reincarnation is 7.776%.
Given that based on a poll, 60% of adults believe in reincarnation, to determine, assuming that 5 adults are randomly selected, what is the probability that exactly 4 of the selected adults believe in reincarnation, and what is the probability that all of the selected adults believe in reincarnation, the following calculations must be performed:
- 0.6 x 0.6 x 0.6 x 0.6 x 0.4 = X
- 0.36 x 0.36 x 0.4 = X
- 0.1296 x 0.4 = X
- 0.05184 = X
- 0.05184 x 100 = 5.184
- 0.6 x 0.6 x 0.6 x 0.6 x 0.6 = X
- 0.36 x 0.36 x 0.6 = X
- 0.1296 x 0.6 = X
- 0.07776 = X
- 0.07776 x 100 = 7.776
Therefore, the probability that exactly 4 of the selected adults believe in reincarnation is 5.184%, and the probability that all of the selected adults believe in reincarnation is 7.776%.

So a box has 5.2 oz
it takes 0.7 oz to clean one load
with 3 boxes (3 times 5.2) how many can be cleaned
3 times 5.2=15.6
15.6/0.7=156/7 how many loads=22 and 2/7 =22.285 loads or less than 22 loads (since you can't clean a decimal of a load)
22 Loads is the answer
If the side of the square flower bed was enlarged by 8 feet and the area of the new flower bed was 3 times the area of the old one then the length of the side of the old flower bed was 4 feet.
Given that the side of square flower bed was enlarged by 8 feet and the area of the new flower bed was 4 feet.
We are required to find the length of the side of the old flower bed.
We know that the area of rectangle is equal to the product of length and breadth of that rectangle.
let x represents the side of the square old flower bed.
Dimensions of new rectangular flower bed:
Width=x
Length =x+8
Area=3*
=3
Thus:
x(x+8)=3
+8x=3
2
=8x
2x=8
x=4
Hence if the side of the square flower bed was enlarged by 8 feet and the area of the new flower bed was 3 times the area of the old one then the length of the side of the old flower bed was 4 feet.

Answer:
c = 15: The height of candle is 15 inches when it is not lit.
m = -1.6: The height of candle decreases 1.6 inches for every hour it is lit.
Step-by-step explanation:
We are given the following in the question:
Height of candle = 15 inches

This function gives the length of the candle in inches left after it was burn for t hours.
Comparing the given equation to a linear equation, we have:

where m is the slope and c is the y-intercept.
Comparing we, get
m = -1.6 and c = 15
Interpretation:
c = 15 mean the y-intercept is 15 that is he value of function when t = 0, thus, the height of candle is 15 inches when it is not lit.
m = -1.6 is the rate of change of the function when t increases by 1 unit that is the height of candle decreases 1.6 inches for every hour it is lit.
