A family moved to Orlando, FL and bought a home. They paid $254,876 for their house. In their neighborhood the mean price of a h

ome is $267,985 with a standard deviation of $5,834. Calculate the z-score for the price of their home and indicate if the price they paid for their home usual or unusual?

Answer:

Step-by-step explanation: standard score is equal to sample mean - population mean all over standard deviation.

Z=×-u/sigma. Where sigma is standard deviation. 267985-254876=13109. 13109/5834=2.247. Therefore the standard score is 2.247. The price they paid for the house is usual.

A force of 3 pounds is required to hold a spring stretched 0.6 feet beyond its natural length. how much work (in foot-pounds) is
ioda

The work done (in foot-pounds) in stretching the spring from its natural length to 0.7 feet beyond its natural length is 1.23 foot-pound

<h3>Data obtained from the question</h3>

From the question given above, the following data were obtained:

  • Force (F) = 3 pounds
  • Extension (e) = 0.6 feet
  • Work done (Wd) =?

<h3>How to determine the spring constant</h3>
  • Force (F) = 3 pounds
  • Extension (e) = 0.6 feet
  • Spring constant (K) =?

F = Ke

Divide both sides by e

K = F/ e

K = 3 / 0.6

K = 5 pound/foot

Thus, the spring constant of the spring is 5 pound/foot

<h3>How to determine the work done</h3>
  • Spring constant (K) = 5 pound/foot
  • Extention (e) = 0.7 feet
  • Work done (Wd) =?

Wd = ½Ke²

Wd = ½ × 5 × 0.7²

Wd = 2.5 × 0.49

Wd = 1.23 foot-pound

Therefore, the work done in stretching the spring 0.7 feet is 1.23 foot-pound
