<u>2. What is P(M), the probability that a student plans to major in mathematics?</u>
- P(M) = number of students who plan to major in mathematics / number of students
Answer:
x = 107°
Step-by-step explanation:
The sum of all 3 angles in any triangle needs to equal 180°.
This means that 44° + 29° + x = 180°
180° - 44° - 29° = 107°
Answer:
18 days
Step-by-step explanation:
Let x represent number of days.
We have been given that Brandy's watch falls 1 second every day. So Brandy's watch will fall 
seconds behind in x days.
We are also told that Brandy set her watch 4 seconds behind, so Brady's watch will be behind by total 
seconds in x days.
Since Brady's watch is 22 seconds behind, so we will equate by 22 to solve for x as:
Therefore, Brandy set her watch 18 days ago.
Answer:
6 quarters 2 dime 3 nickels
Step-by-step explanation:
Not sure if you want an equivalent fraction for 2/3 or 2 and 3 so I will give both!
2 can be any fraction where the numerator is 2x larger than the denominator.
Example, 2/1, 4/2, 6/3, 8,4 etc.
3 can be any fraction where the numerator is 3x larger than the denominator.
Example, 3/1, 6/2, 9/3, 12/4 etc.
An equal fraction to the fraction 2/3 would be anything that has a numerator is 2/3x larger than the denominator.
Example, 4/6, 6/9, 8/12 etc.
Hope this helps. :)
