Answer: 0.6274
Step-by-step explanation:
Given: The proportion of patients experience injection-site reactions with the current needle : p=0.11
Sample size : n= 4
Let x be a binomial random variable that represents the people get an injection-site reaction.
Binomial probability formula: 
The required probability : P(x=0)

Hence, the probability that none of the 4 people get an injection-site reaction = 0.6274
Answer:
15
Step-by-step explanation
There are 4 children. They each get 2 pieces. 2*4=8 Joe had 7 candies for himself. 8+7=15.
Converting 653 to base 10.
6*102=600
5*101=50
3*100=3
Adding all to get Ans=65310
Step2 converting 65310 to 7
The equation calculation formula for 65310 number to 7 is like this below.
7|653
7|93|2
7|13|2
7|1|6
7|1|1
Ans:16227
Answer:
18.84cm
Step-by-step explanation:
There is a formula which for the diameter is pie (3.14) times the diameter. Now if you have the radius it would be pie (3.14) times 2 times whatever the radius would be. Now you could use either formula for this, just divide the diameter by two to get 3.
So 3x2x3.14=18.84cm
So then you could just multiply 6x3.14 and still get 18.84cm
