The number of tourists at the beach per weekend in July was 55,000, In November, the number of tourists per weekend was 18,000.

Ganezh [65]

Answer:

The percentage change from July to November is 67.27 %

Step-by-step explanation:

Given as :

The number of tourists at the beach per weekend in the month of July = $x_1$ = 55,000

The number of tourists at the beach per weekend in the month of November = $x_2$ = 18,000

Let the percentage change from July to November = A %

Or, % decrease change = $\dfrac{\tetxtrm new value - \textrm old value}{\textrm old value}$ × 100

So , A % = $\dfrac{\tetxtrm [tex]x_2$ - \textrm $x_1$ }{\textrm $x_1$ }[/tex] × 100

or, A % = $\frac{55000 - 18000}{55000}$ × 100

Or, A % = $\frac{37000}{55000}$ × 100

Or, A = 67.27 %

So percentage change between two months = 67.27 %

Hence The percentage change from July to November is 67.27 % Answer

Skylar is answering the following math problem: The value of an investment decreased by 10%. The original amount of the investme

Alona [7]

Answer:

The given parameters of the investment are;

The rate of decrease of the investment, r = -10%

The original amount of the investment, P = $75.00

Let 'A' represent the final answer (value of the investment) after the decrease in the investment, 'r', is applied, we have;

The algebraic equation that can be used to arrive at the final answer, 'A', is given as follows;

A = P + r·P

Therefore by substituting the given values, we have;

A = $75.00 + (-10/100) × $75.00 = $75.00 - 0.1 × $75.00 = $75.00 - $7.50

A = $75.00 - $7.50 = $67.50

The final amount or answer, A = $67.50

Find the range of the function: f(x) = x + 3, for x ≠ 1

Tju [1.3M]

Answer:

All Real Numbers except for 4

Step-by-step explanation:

Objective: Specify domain and range of a function.

The equation is a linear equation. A linear equation range is all real numbers. However x cannot equal 1 so let plug in x to find where the y value CANT be.

$f(1) = 1 + 3 = 4$

So the range is
