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:
13-h is h less than 13. this is how you answer this.
Answer:
y = -1/2x + 1/2
Step-by-step explanation:
perpendicular lines have slopes that are opposite signs and reciprocal
therefore, use m=-1/2 and point (9, -4) to complete the equation by finding 'b' (the y-intercept)
-4 = -1/2(9) + b
-4 = -9/2 + b
-4 + 9/2 = b
-4 + 4 
= b
b =
So for every 9 star beads you have, you have 6 moon beads. The rule is dividing.
6 divided by two (because we have two moon beads) is 3.
9 divided by three (because that's the answer to the first part) is 3.
So there are 3 star beads.
Answer:
The answer is x15
