Answer:
3/2
Step-by-step explanation:
In order to find the slope with two points, you use this formula:
y2-y1 / x2 - x1.
y2 is 5 and y1 is -4. 5 - -4 = 9
x2 is 2 and x1 is -4. 2 - - 4 = 6
9/6 = 3/2.
First make 4 1/2 improper
4 1/2 = 9/2
Divide = multiply reciprocal
9/2 * 5/3 = 45/6
Simplify 45/6
Final answer: 7 1/2
Answer:
I'd say A because this question is just like y and xays.
Step-by-step explanation:
All triangles should equal 180 so the answer is B. When you solve it you get 60, 60, 60 which equals 180
1/ 816
Step-by-step explanation:
Step 1 :
Given
Total number of students in the school = 18
Number of students randomly selected = 3
Step 2 :
Number of ways in which 3 students can be selected out of 18 students is
C(18,3) = 18! /(3!(*18-3)!) = 18*17*16/3*2*1 = 816
Number of ways in which 3 students are selected and they are the youngest = 1
Hence the probability of selecting 3 youngest students from the available students is 1/ C(18,3) = 1/ 816
