Answer: Min : $750\ ,\ Q_1= \$800\ ,\ Median : \$925\ ,\ Q_3=\$1050\ ,\ Max: \$1100

Step-by-step explanation:

The five -number summary consists of five values :

Minimum value , First quartile (Q_1) , Median , Third Quartile (Q_3)  , Maximum value.

Given : The Insurance Institute for Highway Safety publishes data on the total damage caused by compact automobiles in a series of controlled, low-speed collisions.

The following costs are for a sample of six cars:

$800, $750, $900, $950, $1100, $1050.

Arrange data in increasing order :

$750,$800, $900, $950, $1050, $1100

Minimum value =  $750

Maximum value = $1100

Median = middle most term

Since , total observation is 6 (even) , so Median = Mean of two middle most values ($900 and  $950).

i.e.  Median=\dfrac{900+950}{2}=\$925

First quartile (Q_1) = Median of lower half ($750,$800, $900)

= $800

, Third Quartile (Q_3)  = Median of upper half ($950,  $1050, $1100)

= $1050

Hence, the five-number summary of the total damage suffered for this sample of cars will be :

Min : $750\ ,\ Q_1= \$800\ ,\ Median : \$925\ ,\ Q_3=\$1050\ ,\ Max: \$1100

An unknown number w is 30 more than an unknown number p. The number w is also p less than 5
AleksandrR [38]
The problem statement gives rise to two equations.
  w = 30 + p . . . . . w is 30 more than p
  w = 5 - p . . . . . .. w is p less than 5

Add these two equations to get
  2w = 35
  w = 35/2 = 17.5
  p = 5 - w = -12.5

The unknown number w is 17.5.
The unknown number p is -12.5.

Explain a real life situation where you may use trig ratios to find measure in right triangles.
OLEGan [10]
One example is if you wanted to measure the height of a tall building. You'll need to measure the distance from where you're standing to the base of the building. You'll also need the angle of elevation. To get the angle of elevation, start by looking completely horizontal, then tilt upward until your eyeline reaches the top of the building. Once you have those two things (the side and angle) you can use the tangent ratio to find the height. This is because

tan(angle) = opposite/adjacent

where in this case
angle = angle of elevation
opposite = height of building
adjacent = distance from your position to the base of the building

It takes a bit of algebra, but the opposite side can be solved for. You'll most likely need a calculator to compute the tangent ratio.

What is the value of x?
yuradex [85]

Answer:

the value of x is the answer.

Step-by-step explanation:

ok so say that there is a question that you get and it says 9 (x-2) ok so then you would take the x and replace it with the 9 so then you do (9-2=7 so then you would have x=7
