Answer:
<h2>
3/5</h2>
Step-by-step explanation:
If Jennifer has 25 books on her bookshelf and she has 10 fiction books, the number of non-fiction books she has will be 25-10 = 15 non- fiction books.
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome of event/total outcome.
Since we want the expression that represents the probability that the book she selects will be a non-fiction book, our expected outcome will be 15(the total non fiction she selected)
The total outcome will be the total number of books i.e 25.
Probability that she elects non fiction book = 15/25
= 3/5
Answer: X= 6 or X=-4
Step-by-step explanation:
Answer:
x + 10 = 4x
Step-by-step explanation:
Let x = her age 10 years ago.
Her age now is x + 10.
x + 10 = 4x
A garph y=2 represents a line parallel to the x axis with the y coordinate equal to 2.
The point which lies on the y=2 graph has its y coordinate equal to 2.
In the given options, (3,2) is the coordinate with the y coordinate equal to 2.
Hence, (3,2) lies on the graph of y = 2.
Option (D) is the answer.
For this case we have that by definition, the circumference of a circle is given by:
Where:
d: It is the diameter of the circle
They tell us that:
Substituting:
Thus, the circumference of the circle is 55 centimeters.
