The IQR tells you how spread out the "middle" values are. It can also be used to figure out if there are any outliers.

Ruby tosses a quarter off the main stree bridge into the St. John's River. The distance, in feet, the quarter is above the water
MatroZZZ [7]

Step-by-step explanation:

d(t) = -16t² + 96t + 112

A) The quarter's initial height is at t = 0.

d(0) = -16(0)² + 96(0) + 112

d(0) = 112

The quarter is tossed from a height of 112 feet.

B) The maximum height is at the vertex of the parabola, which is at x = -b/(2a).

t = -(96) / (2 × -16)

t = 3

The quarter reaches its maximum height after 3 seconds.

C) d(3) = -16(3)² + 96(3) + 112

d(3) = 256

The quarter reaches a maximum height of 256 feet.

D) When the quarter lands in the water, d(t) = 0.

0 = -16t² + 96t + 112

0 = t² − 6t − 7

0 = (t + 1) (t − 7)

t = -1 or 7

Since t can't be negative, t = 7.  So the quarter lands in the water after 7 seconds.

      Hey There!! (❁´◡`❁)

  1. The answer to this is: Map Key. Because, Large scale maps are typically used to show site plans, local areas, neighborhoods, towns etc. ... A 'small' scale map is one in which a given part of the Earth is represented by a small area on the map. Small scale maps generally show less detail than large scale maps, but cover large parts of the Earth.    
  2. The answer to this is: North. Like the wind rose, the compass rose was coincidentally designed in a fashion that resembled the rose flower. It helped to orient a map in the proper reading direction and gave the relative directions for certain points on the chart. Before compass roses were used on maps, lines were drawn from central points.
  3. The answer to this is: Map. Because, a Map help you to find places where you need to go.
  4. The answer to this is: Map Key. Because, A map usually has a legend, or key, that gives the scale of the map and explains what the various symbols represent. Some maps show relief, or changes inUsedLess elevation. A common way to show relief is contour lines, also called topographic lines.
  5. The answer to this is: Blue. Because Blue Water is mostly associated with the color blue. Uncolored versions of these symbols can be found in Earth, Air, Fire and Water Symbols.
  6. The answer to this is: Help you find directions: Because, A compass rose, sometimes called a windrose or rose of the winds, is a figure on a compass, map, nautical chart, or monument used to display the orientation of the cardinal directions (north, east, south, and west) and their intermediate points.
  7. The answer to this is: A system of vertical and horizontal lines. A grid system on a map is usually square and is represented by drawn lines on the map creating those squares. The purpose of the grid system is to give each point in the map an identifier, an address, by which we can refer to it by.
  8. The answer to this is: Map key Title, date, author, and sources usually appear on the map though not always together. The map's title tells what the map is about, revealing the map's purpose and content. For example, a map might be titled “Political Map of the World” or “Battle of Gettysburg, 1863.”

A box contains 14 large marbles and 11 small marbles. Each marble is either green or white. 8 of the large marbles are green, an
prisoha [69]

Answer:

Step-by-step explanation:

Given that:

Number of Large Marbles = 14

Number of Small Marbles = 11

Number of Green large marbles = 8

Number of White small marbles = 5

We can now find the number of white large marbles and green small marbles from the information stated above.

No of white large marble = total large marble minus green large marble

= 14-8

= 6

No of green small marbles = Total small marbles minus white small marble.

= 11-5

= 6

Let the following be represented

( X,Y, Z,Q ) as follows:

Let Y be the event of drawing small marble

Let X be the event of drawing large marble

Let Q be the event of drawing white marble

Let Z be the event of drawing green marble.

Since, only one marble is drawn at a time we calculate,

P( X ) = 14/25

P( Y) = 11/25

P(Z) = 14/25

P( Q) = 11/25

P(Y∪Q)=P(Y)+P(Z)−P(Y∩Z)...(1)

We need to find the value of

P(Y∩Z)

In 11 small marbles there are 6 green marbles so the value of P(Y∩Z) is given by P(Y∩Z)=6/11

Therefore, substitute the values in equation 1.

P(Y∪Z)=P(Y)+P(Z)−P(Y∩Z)=11/25+14/25-

6/11

=0.44+0.56−0.5455

= 1-0.5455

= 909/2000

= 0.4545

Then, one can conclude that the probability of drawing a small or green marble is 0.4545
