Vlad1618 [11]

Answer:

- 12 meters

28 meters

40 meters

Step-by-step explanation:

Given that:

A fish is 12 meters below the surface of the ocean. What is its elevation?

Position of fish = 12 meters below the surface = - 12 ;

Sea level = 0

Elevation = sea level + position

Elevation = 0 + (- 12)

= - 12 meters

2. A sea bird is 28 meters above the surface of the ocean. What is its elevation?

Position of bird = 28 meters below the surface = (28) ;

Sea level = 0

Elevation = sea level + position

Elevation = 0 + 28

= 28 meters

3. If the bird is directly above the fish, how far apart are they?

If bird is directly above the fish;

Distance between bird and fish :

Elevation of bird - elevation of fish

28 - (-12)

28 + 12

= 40 Meters

Assume that Thermometer readings are normally distributed with a mean of 0°C and standard deviation of 1.00°C. A Thermometer is

Ne4ueva [31]

Answer:

0.2857

Step-by-step explanation:

The probability of interest is the area under the probability density curve between the z-values associated with the temperature limits of interest.

__

The first attachment shows a "sketch" of the distribution and the area of the portion of interest. (It also shows the probability as 0.2858.)

__

The second attachment shows the table values of interest for this problem. The z-values that we want to look for in the table are ...

z1 = (0.50° -0°)/1.00° = 0.50

and

z2 = (2.00° -0°)/1.00° = 2.00

The area of the probability density function to the left of each of these z-values is given in the table, so the area between them is the difference of table values:

0.9772 -0.6915 = 0.2857

The probability of a reading between 0.50 and 2.00 is about 0.2857.

Managers at an automobile manufacturing plant would like to estimate the mean completion time of an assembly line operation, . T

Vinil7 [7]

Answer:

The appropriate answer is "144".

Step-by-step explanation:

Given:

Population standard deviation,

$\sigma=10.4$

Margin of error,

$E=1.7$

$CL=95$ %

$CL=1-\alpha$

Or,

$\alpha=1-CL$

$=1-0.95$

$=0.05$

Now,

Critical value,

= $Z_{\frac{\alpha}{2} }$

= $Z_{\frac{0.05}{2} }$

= $1.96$

The minimum sample size will be:

⇒ $n=\frac{Z^2_{\frac{\alpha}{2} }(\sigma)^2}{E^2}$

By putting the values, we get

$=\frac{(1.96)^2(10.4)^2}{(1.7)^2}$

$=\frac{415.5074}{2.89}$

$=143.774$

or,

$=144$
