Answer:
% Apple juice =
× Y × 100.
Step-by-step explanation:
Given:
Ratio of apple juice to water = 4 : 3 = Y i.e 4+ 3 = 7
To find the exact % of apple juice used in recipe, we use the ratio of juice to water provided, given Y as any amount of apple cider.
∴ equation
× Y = amount of apple juice.
for percentage,
× Y × 100 = amount of apple juice.
Proof:
In 200ml apple cider, amount of apple juice present
= 4/7 × 200 = 114.2ml of juice
To make upto 00ml cider, add (200-114.2)ml of water.

Answer:
Jones(20%), Smiths(30%)
Step-by-step explanation:
The relative dispersion of a data set is the ratio of its standard deviation to its arithmetic mean.
Mr. and Mrs. Jones' neighborhood mean family income is $45,000 with a standard deviation of $9,000.
Their Relative Dispersion is given as:
Standard Deviation: Mean
9000:45000
1:5
Expressed as a Percentage: (1/5)x100=20%
The Relative Dispersion of the family incomes in Mr. and Mrs. Jones' neighborhood is 20%
Mr. and Mrs. Smith's neighborhood mean family income is $100,000 and the standard deviation is $30,000.
Their Relative Dispersion is given as:
Standard Deviation: Mean
30000:100000
3:10
Expressed as a Percentage: (3/10)x100=30%
The Relative Dispersion of the family incomes in Mr. and Mrs. Smith's neighborhood is 30%
