Answer:
![Probability = \frac{6}{29}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B6%7D%7B29%7D)
Step-by-step explanation:
Given
------------------------------Has a brother | Does not have a brother
Has a sister
--------------------------- 6 ----------------- 8
Does not have a sister -----------2 ------------------ 13
Required
Probability of having a sister and a brother
First, the total number of students has to be calculated;
Total = 6 + 2+ 8 + 13
Total = 29
Number of students that have a sister and a brother is represented with data in row 1 and column 1 i.e. 6
At this point, the probability can then be calculated;
Probability = Number of students that have a sister and a brother divided by Total number of students
![Probability = \frac{6}{29}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B6%7D%7B29%7D)
Answer:
2/9
Step-by-step explanation:
1/3 converted to 9ths is 3/9ths
add apples to oranges
3/9 + 4/9 = 7/9
7/9ths is the amount that is apple and orange
subtract all fruit (9/9) from the fruit accounted for (7/9)
9/9 - 7/9 = 2/9
2/9 is non-reducible therefore
your answer is 2/9 bananas
hope this helps:)
-3x=15
Divide both sides by -3 to get + x
-3x/-3= 15/-3
Cross out -3 and -3 , divide by -3 and then becomes 1*1*x= x
x=-5
Answer: x= -5
Option D.
First We need to find the center of the circle using midpoint formula.
2) we have to find the radius
3)substitute it in the equation of circle.
