I'm not sure about 2-3 but I am gonna say that 1 is (a) because of the gaps in the numbers and the gaps in the points on the graph.
the gap in 1st and 2nd numbers is a pretty big gap 2nd and 3rd gap not so big but 3rd and 4th again pretty good gap
Answer:
Step-by-step explanation:
5z-6-34=z-6
combine like terms (-6-34)
5z-40=z-6
subtract z on both sides
5z-z-40=-6
4z-40=-6
add -40 on both sides
4z=34
divide both sides by 4
z=
hope this helps
Since the distance is 3.667km and the time is 1/3 of an hour (20 minutes) we take the distance and divide it with time 3.667/20 thus the answer is
0.183 km/hr
Answer:
(a) P=0.694
(b) It is independent, beacuse the probability of having the disease for the children depends only on her mother condition (if she has the disease or not), not the condition of his brothers and sisters.
(c) P=0.25
Step-by-step explanation:
(a) If the mother has 0.33 probabilities of having the disease, the probability of the children having the disease is equal to the product of the probability of the mother having the disease (0.33) and the probability of inherit it (0.50).
So the probability of one child of having the disease is 0.33*0.5=0.167. The probability of not having the disease is then (1-0.167)=0.833
The probability of both children to not have the disease is 0.833^2=0.694.
(b) It is independent, beacuse the probability of having the disease for the children depends only on her mother condition (if she has the disease or not), not the ones of his brothers and sisters.
(c) If the mother has the disease, the child have a probability of 0.5 of having the disease.
The probability, given that the mother has the disease, of both child not having the disease is 0.5^2=0.25.
