Answer:
The probability that more than half of them have Type A blood in the sample of 8 randomly chosen donors is P(X>4)=0.1738.
Step-by-step explanation:
This can be modeled as a binomial random variable with n=8 and p=0.4.
The probability that k individuals in the sample have Type A blood can be calculated as:
Then, we can calculate the probability that more than 8/2=4 have Type A blood as:
Answer:
x^2 + (y – 3)^2 = 36
Step-by-step explanation:
The standard equation of a circle with center at (h, k) and radius r is
(x - h)^2 + (y - k)^2 = r^2.
If the center lies on the y-axis, then h = 0: (x - 0)^2 + (y - k)^2 = r^2
If the circle diameter is 12, then the circle radius is 6, and so r^2 = 36
So, among the given equations, your
x^2 + (y – 3)^2 = 36 is correct (but only if you use " ^ " for exponentiation).
Answer:
a) 60%
Step-by-step explanation:
This problem can be solved through binomial probability
Let's say probability of success is the probability of absent
p = 5% = 0.05
Probability of failure
q = 1-p = 0.95
The number of trial in this case is the number of employees randomly selected
n = 10
Since we are looking for 0 absent employee, we are looking for the probability that the success is nil (i.e 0)
x = 0
Binomial therorem
B(n,x,p) = B(10,0,0.05)
= C(10,0) * p^x * q^(n-x)
= 1 * (0.05^0) * (0.95^10)
= 1 * 1 * 0.95^10
= 0.59873693923
= 0.6 or 60%
A cube has 12 edges and each edge is 3 inches. If the ant only crawls on the edges it would be a distance of 36 (3*12)
