Answer: 0.27648
Step-by-step explanation:
Given : The proportion of all individuals have group A blood : p=0.040
Total individuals give blood : n= 6
Let X be the number of individuals have group A blood.
Since all individual are independent of each other.
Formula : 
, where n= sample size , p = probability of getting success in each trial.
The probability that exactly three of the individuals have group A blood. :
The probability that exactly three of the individuals have group A blood. is 0.27648
a)
We know that a 4-sided polygon's angles add up to 360 degrees
so to find x:
360-(69+118+84)=89 degrees
b)
For a 4-sided polygon we also know that the outside angles add up to 360 degree.
so to find p:
360-(100+62+106)=92 degrees
Hope it helps!
The answer is 3. Divide 5375 by 4 to get 1343.75. Remainder for each friend is .75, so multiply .75 by 4. 3 cards left over.
Step-by-step explanation:
Let Andrew wage be = X
Cammi earns $20 more than Andrew So Cammi earns = 20 + X
Brenda earns $30 less than twice Andrew's wage
So she earns = 2X - 30
Their total combanied wage is $400
So Andrew + Cammi + Brenda = $400
X + 20+X + 2X-30 =400
4X - 10 =400
4X=400+10
4X=410
X= $102.5
So Andrew earns $102.5
Cammi earns $122.5
Brenda earns $175
