The length of time a full length movie runs from opening to credits is normally distributed with a mean of 1.9 hours and standar
Margarita [4]

Answer:

  1. 0.26
  2. 0.91
  3. 1.43

Step-by-step explanation:

given data

mean = 1.9 hours

standard deviation = 0.3 hours

solution

we get here first  random movie between 1.8 and 2.0 hours

so here

P(1.8 < z < 2 )

z = (1.8 - 1.9) ÷ 0.3

z = -0.33

and

z = (2.0 - 1.9) ÷ 0.3

z = 0.33

z = 0.6293

so

P(-0.333 < z < 0.333 )

=  0.26

so random movie is between 1.8 and 2.0 hours long is 0.26

and

A movie is longer than 2.3 hours.

P(x > 2.3)

P( \frac{x-\mu }{\sigma}  > \frac{2.3-\mu }{\sigma} )

P (z  > \frac{2.3-1.9 }{0.3}  )

P (z  > 1.333  )

= 0.091

so chance a movie is longer than 2.3 hours is 0.091

and

length of movie that is shorter than 94% of the movies is

P(x > a ) = 0.94

P(x <  a ) = 0.06

so

P( \frac{x-\mu }{\sigma } <  \frac{a-\mu }{\sigma } )

\frac{a-1.9 }{0.3 } = -1.55

a = 1.43

so length of the movie that is shorter than 94% of the movies about 1.4 hours.

Surface area is always measured in square units.<br><br> True<br> False
OLEGan [10]
<h3>Answer: True</h3>

Often we replace "units" with something like "feet" or "meters"

examples: square feet, square meters, square yards, etc

The "square" refers to the idea that any surface area can be unwrapped and lay flat, then you can break the area of that flat figure into smaller squares. A good example of this is a dice has 6 faces and each face is a square itself, so the total surface area is the sum of all the 6 square areas.
