How many 4 card hands that contain exactly 3 aces and 1 queen can be chosen from a 52 card deck?
sesenic [268]
There are 16 possible hands.

Choosing 3 aces from 4 possible is expressed by:
_4C_3=\frac{4!}{3!1!} = 4

Choosing 1 queen from 4 possible is expressed by:
_4C_1=\frac{4!}{1!3!}=4

This gives us 4*4 = 16 possible hands.

An engineer estimated the weight of a steel beam to be 600 pounds. The actual weight of the beam was 639 pounds. Find the absolu
mario62 [17]

Answer:

Absolute error = 39

Percent Error = 6.10%

Step-by-step explanation:

Actual value = 639 pounds

Observed Value = 600 pounds

The formula to find absolute error is:

Absolute Error = Actual value - Observed Value

                        = 639 - 600

                        = 39

The formula to find Percent error is:

Percent Error = (Actual value - Observed Value / Actual value)*100

                       = (639 - 600/639)*100

                       = 6.10%
