Answer:

18/19 = About 95%

Step-by-step:

If only six are noble gases, 108 are not noble gases.

114-6= 108

So, the probability of not picking a noble gas is 108 out of 114. This simplifies to 18/19 which is about 95%.

The interval​ time, I, in​ minutes, between appointments is related to total number of minutes T that a doctor spends with patie
zmey [24]

Answer:

Approximately 5.19 hours.

Step-by-step explanation:

The question is asking that you solve for T (the amount of time spent with patients in a day). To do so, simply input the values which it has given you for your variables. We can substitute 16 for I as that is the doctor's preferred interval time and we can substitute 21 for N as that is the amount of appointments the doctors wishes to have per day.

16=1.08(\frac{T}{21} )

To solve, start by multiplying both sides by 21.

336=1.08T

Next, divide both sides by 1.08.

311.11=T

Your answer comes out to 311.11 minutes. The question is asking for this to be translated into hours per day, which equates to approximately 5.19 hours.

roasted beef protein = 20 grams  ( mean value )

sample size of soybean compound = 5

mean value of their protein = ( 15 + 22 + 17 + 18 + 23)  / 5 = 19

The conditions that have been met are :

The data is a random sample from the population of interest. and

we can say the sample size is less than 10% of population size because we do  know the population size is a large supply
