Answer:
1) 0.1504
2) 0.432
Step-by-step explanation:
1) The given information are;
The proportion of the morning appointments that are with elderly patients = 60%
The number of patients in the appointments = 10 patients
The proportion of the morning appointments that are with non-elderly patients = 100 - 60 = 40%
The binomial probability distribution is given as follows;
= 0.000105
= 0.0016
= 0.01062
= 0.0425
The probability that the first four patients are elderly is 0.000105 + 0.0016 + 0.1062 + 0.0425 = 0.1504
2) The probability that exactly 2 out of 3 morning patients are elderly patient is given as follows
= 0.432
Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees.
Answer:
18 ferrets
Step-by-step explanation:
From the statement you can write the following:
c+r+f= 108
c=cats
r= rabbits
f= ferrets
Then, you have that one third of the animals are cats:
c= 108*(1/3)= 36
Next, three fourths of the remaining animals are rabbits:
r= (108-36)*(3/4)= 72*(3/4)= 54
Now, as you have determine the amount of cats and rabbits, you can isolate f and find the amount of ferrets:
f=108-c-r
f=108-36-54
f= 18
According to this, the answer is that there are 18 ferrets.
Answer:
2
Step-by-step explanation:
this took me 2years to solve
That would be at quadrant to so you want to plot -1 and then half a box to the left. Then you want to point -5 and then just go up half. Hope this helps
