Answer:
D,E are not functions
Step-by-step explanation:
A function is a relation in which every input has not more than one output.But the output of the inputs may be same.Here in D the input 1 has 4 different outputs as 1,2,3,4.So its not a function.Similarly in E 6 has 2 outputs as 2 and -1.For remaining sets the inputs has only one output.so they are functions.
Answer:
The probability of being older than 25 years and having a hemoglobin level above 11 is 19.58%. Since the question is referring to persons older than 25 years, we'll include all the data above 25 years.
So under 25-35 years old is 44 and under 35 years old is 40.
44 + 40 = 84
84 / 429 = 0.1958 or 19.58%
The probability of having a hemoglobin level above 11 is 35.66%. We would just get the ratio of 153 people who have hemoglobin level above 11 over the population of 429. 153 / 429 = 0.356643 or 35.66%
Being older than 25 years and having a hemoglobin level above 11 is not dependent on each other. Since the data is inversely proportional. The older the person gets, the lesser the number of people having hemoglobin level above 11 (A) 19.58%.
I hope this helps!
Answer:
the son is 30 and the daughter is 15
Step-by-step explanation:
the mom is 55 in 15 years
100-55=45
45-30=15
15x2=30
First you would figure out what "x" equals. And then you would replace the "x" in your problem to figure out what the answer is.
I think it is c sorry if I get it wrong
