Answer:
0.40
Step-by-step explanation:
Members who run only long distance = 8%
So, probability that a member will run only long distance = P(A) = 0.08
Members who compete only in field events = 32%
So, probability that a member will compete only in field events = P(B) 0.32
Members who are sprinters = 12%
So, probability that a member is sprinter = P(C) 0.12
We have to calculate the probability that a randomly chosen team member runs only long-distance or competes only in field events. i.e we have to find P(A or B). Since these events cannot occur at the same time, we can write:
P(A or B) = P(A) + P(B)
Using the values, we get:
P(A or B) = 0.08 + 0.32 = 0.40
Thus, the probability that a randomly chosen team member runs only long-distance or competes only in field events is 0.40
Answer: C the set of all integers, the set of all rational numbers, and the set of all real numbers
Step-by-step explanation: The value of square root of 9 is ±3. This means that there two answers to square root of 9: 3 and -3.
As far as 3 is concerned, it is one of the elements of the natural number set. It is already known that natural numbers are also whole numbers, also integers, also rational numbers, and also real numbers.
As far as -3 is concerned, it is not a natural number since the set of natural numbers does not contain negative numbers. -3 is an integer. Which means that -3 is also a rational number and also a real number.
After identifying the common sets and taking the intersection of both the above classifications, it yields the set of all integers, the set of all rational numbers, and the set of all real numbers
Hopes this helps bro
y=2x+5
2(2x+5)+4x=10
4x+10+4x=10
8x=20
So there's one solution, x=2.5
Answer:59.3km
Step-by-step explanation:
Convert 5346m to km to give= 5.346km
Then 4536cm to km gives 0.04536km
Total 5.39136km/day
In eleven days, multiply km per day by 11
It gives 59.3km
