Answer:
86,664 randomly selected U. S Adults
Step-by-step explanation:
The sample is a subset of the population, that is a representative observation which is chosen from a larger population usually used in place of the population due to various reasons which may hamper the use of the entire population on a certain research project. Here, the population of interest is the entire U.S adult.
The subset of the population employed is the 86,664 randomly sampled US adults, this is called the sample as it representative of the population of interest.
Answer:
16 inches
Step-by-step explanation:
Perimeter of a rectangle is
P = 2(l+w)
=2(6+2)
=2(8)
= 16 inches
5x + 3x = 64
8x = 64
x = 8
If we then insert that...
5(8) = 40 fl oz strawberry
3(8) = 24 fl oz water
Answer:
52:49
Step-by-step explanation:
pink:green
The ratio of pink to green marbles is
3k:4k
He removes 5 green marbles and adds 8 pink marbles.
Now the ratio of pink to green marbles is
(3k + 8):(4k - 5)
This rario is equal to 29:23.
(3k + 8)/(4k - 5) = 29/23
29(4k - 5) = 23(3k + 8)
116k - 145 = 69k + 184
47k = 329
k = 7
Original amounts:
3 * k = 3 * 7 = 21 pink
4 * k = 4 * 7 = 28 green
Original total = 21 + 28 = 49
Amounts after replacement:
3k + 8 = 3(7) + 8 = 29 pink
4k - 5 = 4(7) - 5 = 23 green
Total after replacement = 23 + 29 = 52
Answer: The ratio of the total number of marbles in the jar after replacement to the total number of marbles in the jar originally is 52:49.
