Times for a surgical procedure are normally distributed. There are two methods. Method A has a mean of 33 minutes and a standard
lilavasa [31]

Answer:

Method A.

Step-by-step explanation:

For solving this question we need to find out the z-scores for both methods,

Since, the z-score formula is,

z=\frac{x-\mu}{\sigma}

Where, \mu is mean,

\sigma is standard deviation,

Given,

For method A,

\mu = 33

\sigma=8

Thus, the z score for 34 is,

z_1=\frac{34-33}{8}=0.125

While, for method B,

\mu = 37

\sigma = 4

Thus, the z score for 34 is,

z_2=\frac{34-37}{4}=-0.75,

Since, z_1 > z_2

Hence, method A is preferred if the procedure must be completed within 34 minutes.

fiona draws a 24 centimeter rectangle.gregory draws a 24 square inch rectangle.whose rectangle is in area .how do you know
Valentin [98]

Answer:

Therefore we come to a conclusion that,

Gregory's Rectangle is in Area.

Step-by-step explanation:

Given:

Fiona draws a 24 centimeter rectangle.

Gregory draws a 24 square inch rectangle.

To Find:

Whose rectangle is in area = ?

Solution:

Rectangle has a dimension as

Length and Width which are in meters, centimeters, inches, feet, units, etc.

For Area

Area\ of\ Rectangle=Length\times Width

here units are getting Multiplied so it becomes

unit × unit = unit²  = square units

m × m = m² =square meter

inch × inch = inch² =square inches

Hence Area is calculated in square units.

Therefore we come to a conclusion that,

Gregory's Rectangle is in Area.

A plane flew for 2 hours at 467 mph (miles per hour) and 5 hours at 536. How far did the plane fly in miles
Archy [21]

Answer:

3614 miles

Step-by-step explanation:

Given data

A plane flew for 2 hours at 467 mph

Let us find the distance covered

Speed= distance/time

Distance= speed*time

Distance= 467*2

Distance=934 miles

5 hours at 536

Let us find the distance covered

Speed= distance/time

Distance= speed*time

Distance= 536*5

Distance=2680 miles

Total distance

=2680+934

=3614 miles
