Answer:
a) 220
b) 10
c) 4.55% probability that the selected group will consist of all women.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the people are selected is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
a. In how many ways can three people be selected from this group of twelve?
b. In how many ways can three women be selected from the five women?
Three women, from a set of 5. So
c. Find the probability that the selected group will consist of all women.
Desired outcomes:
3 women from a set of 4. So
Total outcomes:
3 people, from a set of 12. So
Probability:
4.55% probability that the selected group will consist of all women.
Answer: 1.2704 ohm
Step-by-step explanation:
Since resistance is directly proportional to the length of the conductor.
Let x be the resistance of the same conductor at 800 feet.
Then by direct proportion,
hence, the resistance of same conductor at 800 feet = 1.2704 ohm
Answer:
a. True, because they are corresponding angles.
b. False, because angles 1 and 2 are supplementary, meaning that they add up to 180 degrees, but 125 + 65 = 190 degrees.
c. True, because they are corresponding angles.
d. True, becuase they are two angles that add up to 180 degrees.
e. True, because they are both interior angles on opposite sides of the transversal.
Your answer is option d. (3,-1)
Answer: 14-degree decrease
Step-by-step explanation:
because it is getting colder and we know this because anytime temperature goes from positive to negative it becomes mad cold.
Anyways subtracting 14 from our initial temp at 8 degrees celsius brings us to a brisk -6 celsius
