Chloe's college raises the cost of room and board per semester. This increase raises Chloe's opportunity cost of attending colle
drek231 [11]

Answer:

The answer is "Option C"

Step-by-step explanation:

The choices were missing in the question, which is defined in the attached file please find it.

To attend university, Chole should pay the cost of a room and board each semester.  Even though the Chole will not be in college, she will still have a room as well as a board and continue living.  

  • If she will not attend college, it also has to equate rooms and board costs per six months since increase towards the room or board charges.  
  • If there's an increase in rooms and boarding costs because she did not understand below the rise in their school fees, therefore the financial cost reduces that desire of she attend.

The life in hours of a thermocouple used in a furnace is known to be approximately normally distributed, with standard deviation
Effectus [21]

Answer:

62 is the minimum sample size needed

Step-by-step explanation:

We know that the population is approximately normally distributed so we will use a z-score for 95% confidence, which is 1.96.  We are given the population standard deviation of σ = 20, and are given that the error should be 5 or less hours.  The fact that it gives us sample data is irrelevant since we are told the population is approximately normally distributed and are given the population standard deviation.

See the attached photo for the calculation of the minimum sample size

If 30% of John's photographs were perfect, but 210 photographs were not perfect, then how many photographs were there in all?
loris [4]
If 30% were perfect, 70% were not perfect.  So we know that 70% of the total number of photographs is 210.

p(70/100)=210  multiply both sides by 100

70p=21000  divide both sides by 70

p=300

So there are 300 photographs in all.
