The given function f gives the distance of a dog from a post in feet as a function of time t in seconds since the owner left. We wrote 3 true statements about this situation using function notation.

Given a function f, which gives the distance of a dog from a post in feet as a function of time t in seconds since the owner left. We need to write 3 true statements about this situation using function notation.

1) Let's consider the function f(t), the input t is the time since the owner left, and the output f(t) is the distance of the dog from the post.

2) Since the function f gives the distance of the dog from a post, it can only take non-negative values. Therefore, the domain of the function is the set of non-negative real numbers.

3) If the dog is stationary, that means the distance from the post will be zero, which means that the value of the function f(t) will be zero when t is equal to zero

Conclusion:In summary, the given function f gives the distance of a dog from a post in feet as a function of time t in seconds since the owner left. We wrote 3 true statements about this situation using function notation.

The Mae takes the absolute values of the forecast errors to ensure they don't cancel each other out.

By considering only the magnitude of the errors, the MAE (Mean Absolute Error) provides a measure of the average deviation between forecasts and actual values.

To ensure that forecast errors don't cancel each other out, the Mean Absolute Error (MAE) calculation involves taking the absolute values of the errors. The MAE is a commonly used metric to measure the accuracy of a forecasting model.

Forecast errors represent the differences between predicted values and actual values. These errors can be positive or negative, depending on whether the forecast overestimates or underestimates the actual value. By taking the absolute values, the direction of the error is disregarded, and only the magnitude of the deviation is considered.

By summing up the absolute values of all the forecast errors and dividing by the number of observations, the MAE provides an average measure of how far the forecasts deviate from the actual values. It allows for the evaluation of the average absolute magnitude of the errors without considering their direction.

In summary, the Mean Absolute Error (MAE) takes the absolute values of the forecast errors to ensure they don't cancel each other out. This approach allows for a measurement of the average deviation between forecasts and actual values by considering only the magnitude of the errors.

To find the number of years it will take for the population of a city to increase from 120000 to 180000, we need to use the formula:

Years = log (target population / starting population) / log (1 + annual growth rate)

Where the annual growth rate is 2.5% or 0.025.

Plugging in the values, we get:

Years = log (180000 / 120000) / log (1 + 0.025)

Years = log (1.5) / log (1.025)

Years = 7.36 years

Rounding to the nearest tenth, we get:

Years = 7.4 years

So it will take approximately 7.4 years for the population of the city to increase from 120000 to 180000 people, assuming a constant annual growth rate of 2.5%.

The given infinite geometric series converges, its sum is 1/4.

To determine the sum of the infinite geometric series 1 - 3 + 3^2 - 3^3 + ..., we can use the formula for the sum of an infinite geometric series. The formula is as follows:

S = a / (1 - r),

where 'a' is the first term and 'r' is the common ratio.

In this case, the first term 'a' is 1, and the common ratio 'r' is -3.

Substituting these values into the formula, we have:

S = 1 / (1 - (-3)) = 1 / (1 + 3) = 1/4.

Therefore, if the given infinite geometric series converges, its sum is 1/4.

The convergence of an infinite geometric series depends on the absolute value of the common ratio being less than 1. In this case, the absolute value of -3 is 3, which is greater than 1. Hence, the given series does not converge, and as a result, there is no finite sum for this infinite geometric series.

Answer:

The first one is right

Step-by-step explanation:

The absolute value of the PED is greater than 1, which means that the demand for oranges is elastic at this price point.

The 10% increase in price leads to a 20% decrease in quantity demanded, indicating that consumers are sensitive to price changes and will decrease their purchases by a relatively larger proportion compared to the change in price.

The price elasticity of demand measures the change in consumption of a product in response to a price change. If the price elasticity of a good is infinite, it is perfectly elastic (if demand changes substantially even with minimal price change).

If the price elasticity is greater than one, the good is elastic; if it is less than one, the good is inelastic. A good is perfectly inelastic if its price elasticity is 0 (no amount of price change causes a change in demand).

PED = percentage change in quantity demanded / percentage change in price

Using the given values, the percentage change in price is:

%Δprice = (new price - old price) / old price x 100%

%Δprice = ($1.10 - $1) / $1 x 100%

%Δprice = 10%

The percentage change in quantity demanded is:

%Δquantity demanded = (new quantity demanded - old quantity demanded) / old quantity demanded x 100%

%Δquantity demanded = (800 - 1000) / 1000 x 100%

%Δquantity demanded = -20%. This negative sign indicates that the change in quantity demanded is a decrease.

Thus, the PED can be calculated as:

PED = %Δquantity demanded / %Δprice

PED = (-20% / 10%)

PED = -2

Answer:

  (c)  not enough information

Step-by-step explanation:

You want to identify the true statements about whether lines with the same slope are dependent or independent.

Linear equations are classified according to whether they are dependent or independent. Independent equations can be further classified as consistent or inconsistent.

The equations are dependent if one equation can be formed from a linear combination of the other(s). Two dependent equations in two variables will graph as the same line.

In the slope-intercept form of the equation of a line, there are two constants: the slope, and the y-intercept. For two equations to be dependent, both of these constants must be the same.

If only the slopes are the same, there is not enough information to know whether the equations are dependent or independent.

__

Additional comment

If the slopes are the same, but the y-intercepts are different, the equations are independent, but inconsistent. They describe parallel lines. There will not be any values of the variables that will satisfy both equations simultaneously.

A card is drawn randomly from a standard 52-card deck. then the probabilities are a) 1/13 b) 3/13 and c) 10/13

There are four 3's in the deck. This means that, from 52 possible cards to drawn, we have 4 chances of drawing a 3. This means that the probability will be:

p = 4/52

p= 1/13

b.

For every suit, there are three face cards, J, Q and K. There are 4 suits, so, the total number of face cards its:

4*3 =12

The total possible cards are, still, 52, so, the probability will be

p= 12/52

p=3/13

c.

We know that the card drawn must be a face card, o not being a face card. There is no third choice here. So, the probability of drawing a face card OR not drawing a face card its:

p=52/52

p=1

so

p( the card is a face card ) + p( the card is not a face card) =1

but, we know that

p( the card is a face card ) =3/13

so

p( the card is not a face card) =1- 3/13

The function that has the greatest x-intercept is the function h(x)

The x-intercept of a function is the x-value of the function when the y-value is 0, which is the set of points at which the graph of the function intersects the x-axis.

The x-intercept of each function are found as follows;

f(x) = 3·x - 9 = 0

x = 9/3 = 3

g(x) = |x + 3| = 0

(x + 3) > 0 and |x + 3| = x + 3 = 0

x = 0 - 3 = -3

|x + 3| < 0 and |x + 3| = -(x + 3) = 0

x = -3

h(x) = 2·x - 16 = 0

x = 16/2 = 8

x = 8

j(x) = -5·(x - 2)² = 0

The x-intercept is x = 2

The function that has the greatest x-intercept is therefore the function h(x) = 2·x - 16
