Carpet is sold in square yards. How much carpet would a person need to buy for a rectangular room that has dimensions of 10 yard
Dafna1 [17]

Alright, lets get started.

Here the dimensions of the room are given 10 yards by 18 feet.

We need to first convert this 18 feet into yards to make the units same.

3 feets = 1 yards

1 feet = \frac{1}{3} yards

18 feet = \frac{1}{3}* 18 = 6 yards

It means the dimensions of the room is 10 yards by 6 yards.

So, the carpet we need should be equal to the area of the room.

Area of the room is = 10 * 6

Area of the room = 60 square yards

Hence we need 60 square yards carpet for the room. : Answer

Hope it will help :)

Heights of young adult women in the United States are approximately Normal with a mean of 64 inches and standard deviation 2.7 i
sweet-ann [11.9K]

Answer:

The proportion of all young adult women in the United States are taller than 6 feet(72 inches ) is  

   P( X >  72) =0.0015233

Step-by-step explanation:

From the question we are told that

   The mean is  \mu =  64 \ inches

    The standard deviation is  \sigma =  2.7 \  inches

Generally  6 feet  is equivalent to 6 * 12 = 72 inches

Generally the proportion of all young adult women in the United States are taller than 6 feet(72 inches ) is mathematically represented as

       P( X >  72) =  P(\frac{X - \mu }{\sigma }  >  \frac{72  - 64 }{ 2.7 } )

\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )

       P( X >  72) =  P(Z >  2.963 )

From the z-table

  The area under the normal  curve to the right corresponding to 2.963  is  

     P(Z >  2.963 ) = 0.0015233

=>   P( X >  72) =0.0015233
