Answer:
5/8
Step-by-step explanation:
3/8 + 1/4
To add these fractions, you need a lowest common denominator. Both 4 and 8 "go into" 8, so the lowest common denominator is 8.
In order to change the denominator 4 to 8, you need to multiply both the numerator and the denominator by 2. So, 1/4 becomes 2/8.
Now, the problem is 3/8 + 2/8.
You can add the numerators, because the denominator is the same for each fraction.
3/8 + 2/8 = 5/8
Answer:
Option b
Step-by-step explanation:
A function is even if and only if f(-x) = f(x).
This means that there is the same value of y for 
and for 
Where is any point belonging to the function .
Therefore you must select a graph whose ordered pairs are of the form 
and 
Therefore the correct answer is option b. Assume that each box in the graph equals 1 unit. Then, for x = 2 y = -3 and for x = -2 y = -3. Then it is shown that the function is even.

Probability = number of positive outcomes / number of possible outcomes
Probability that a student in grade 9 is in favor of extending the school day =
number of students in 9 grade in favor / number of students in grade 9
number of students in 9 grade in favor = 5
number of students in 9 grade = 5 + 3 + 9 = 17
Probability = 5 / 17
Answer: 5 / 17
