Answer:
3s-4bbb=17
Step-by-step explanation:
brother=4bbb
sister=3s
3s-4bbb=17
4/(5+3/x)= 1/2 t 8 = 5 +3/x 8x = 5x + 3 or x = 1
i do not confirm that this is correct by the way
Let X be the number of defective transistors. Let p be the probability that defective transistor.
P(defective transistor) = 0.04
P(non defective ) = 1- 0.04 = 0.96
A random sample of size 30 is tested for defects and we want to find probability of no defective transistor
P(No defective transistor) = P(X= 0)
Here X follows binomial distribution with parameters n=30 and p=0.04
The Binomial probability function with parameters n and p is
P(X=x) =
P(X=0) =
Using n=30 and p=0.04
P(X=0) =
P(X=0) = 1*1*(0.96)^30
P(X=0) = 0.2938
The probability that there are no defective transistors in the sample is 0.2938

Answer:
23
Step-by-step explanation:
because there is a 90 degree angle and then the 67 degree angle, and triangle law says that all angles add up to 180.
