The locations in a city are mapped out on a grid, where the origin represents the city center. A traffic helicopter travels due

north and then due east to get to the location at (-3,4) to the location at (7,13).
About how many fewer units would the helicopter have traveled if it went directly from one location to the other?

Answer:

Helicopter have traveled  5.55 units of distance approximately  if it went directly from one location to the other.

Step-by-step explanation:

We are given the following in the question:

A traffic helicopter travels due north and then due east to get to the location at (-3,4) to the location at (7,13).

The attached image shows the path of helicopter.

Distance Formula:

(x_1,y_1), (x_2,y_2)\\\\d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}

Distance traveled by helicopter =

d((-3,4),(-3,13)) + d((-3,13),(7,13))\\\\=\sqrt{(-3+3)^2 + (13-4)^2} + \sqrt{(7+3)^2 + (13-13)^2}\\= 9+10\\= 19 \text{ units}

If the helicopter goes directly:

d((-3,4),(7,13))\\\\=\sqrt{(7+3)^2+(13-4)^2}\\\approx 13.45 \text{ units}

Difference in distances =

19 - 13.45 = 5.55\text{ units}

Thus, helicopter have traveled  5.55 units of distance approximately  if it went directly from one location to the other.

The quotient of 24 and x equals 14 minus 2 times x
vaieri [72.5K]

Answer:

x = 3, x = 4

Step-by-step explanation:

Given

\frac{24}{x} = 14 - 2x ( multiply through by x , x ≠ 0 )

24 = 14x - 2x² ( subtract 14x - 2x² from both sides )

2x² - 14x + 24 = 0 ( divide through by 2 )

x² - 7x + 12 = 0 ← in standard form

(x - 3)(x - 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

x - 4 = 0 ⇒ x = 4

Explain why you cannot calculate the probability that a randomly selected passenger weighs more than 200 pounds?
djyliett [7]

Answer:

We cannot calculate the probability  that a randomly selected passenger weighs more than 200 pounds

Step-by-step explanation:

We cannot calculate the probability  that a randomly selected passenger weighs more than 200 pounds because we do not know the number of possible outcomes, the events , sample space or the sample size. Probability is calculated  with frequency or occurrences or how much certainty there is.It is a number between 0 and 1. 1 indicates certainty and  0 indicates impossibility. Without a range or frequency how can we depict the possibility or impossibility of an occurrence of 200 pounds.
