Answer:
Tests is 100% Accurate, so by using the formula of random variable probability.
Step-by-step explanation:
Total number of people = 10
Sample space = p(A) = 10
Number of people that have flu = n(s) = 4
Pick random 3 persons, the possibility that they have flue is n(A) = ?
Let X is the random variable, consisting of number of positive flu test,
Tests is 100% Accurate, so by using the formula of random variable probability, we get
P(X) = n (A) / n(S)
P(X) = ¾, is the probability of having positive flu test
Answer: 3x -4
Step-by-step explanation:
18.24 pounds on each shelf because the weight divided by the amount of bags would be .96 pounds per bag. And then the total amount of bags divided by the amount of shelves would be 19 so 19x.96 pounds is 18.24 on each shelf
-7 + x = 6x - 12
-7 +12 = 6x - x
5 = 5x
x = 1
hope this helps
Answer: The answer is C) 44 units.
Step-by-step explanation:
The question is asking for perimeter, not area. Instead of multiplying 9*13 to get area, we need to add the sides together. If the width on one side is 13, so is the witdh on the other side. This rule applies to the length as well.
9 + 9 + 13 + 13 = 44, so the perimieter of the rectangle is 44 units.
