1 answer:
Zielflug [23.3K]3 years ago
3 0

Answer:

  To write the equation y = ax + b in function notation, substitute f(x) for y

Step-by-step explanation:

The only true statement is the last one.

__

A function assigns exactly one output value to each input value.

The domain is the set of all input, or x-values.

The range is the set of all output, or y-values.

y=ax+b can be written in function notation by replacing y with f(x).

Age (years) Population Under 15 2600 15 - 64 16000 Over 64 4000 Calculate the child dependency ratio from the chart above. Round
Brums [2.3K]

Answer:

16.25%

=0.163 (correct to 3 decimal places)

Step-by-step explanation:

The child dependency ratio of a population is defined as the number of children (Under 15 years) divided by the working-age population (15–64 years old).

\mathrm{ Child}\;\mathrm{ dependency}\;\mathrm{ ratio}=\dfrac{{\mathrm{ Population}\,\left( \text{Under 15} \right)}}{{\mathrm{ Population}\,\left( {15-64} \right)}}\times 100

From the given table:

Population Under 15 years = 2600

Population of the working class (between 15-64) = 16000

Therefore:

\mathrm{ Child}\;\mathrm{ dependency}\;\mathrm{ ratio}=\dfrac{2600}{16000}\times 100\\\\=16.25\%

=0.163 (correct to 3 decimal places)

-0.70 — (-2/5)+ 0.4 + (-1/4)
Liono4ka [1.6K]

Answer:

-0.15

Step-by-step explanation:

the easiest way to do this is to convert all of the numbers to decimals. -2/5 becomes -0.4, and -1/4 becomes -0.25. Then you simplify the equation to get - 0.7 + 0.4 + 0.4 - 0.25, which you then solve to get -0.15.
