Answer:
(-1,-0.5)
Step-by-step explanation:
We can see from our given graph that Fernando is at point (-4,-2) and Maria is at point (4,2). They will meet at the fountain located somewhere between them.
We can see that fountain will divide our given line segment internally, so we will use section formula, when a point internally divides a segment in ratio m:n.
![[\frac{m*x_2+n*x_1}{m+n},\frac{m*y_2+n*y_1}{m+n}]](https://tex.z-dn.net/?f=%5B%5Cfrac%7Bm%2Ax_2%2Bn%2Ax_1%7D%7Bm%2Bn%7D%2C%5Cfrac%7Bm%2Ay_2%2Bn%2Ay_1%7D%7Bm%2Bn%7D%5D)
Let location of Maria be point
and location of Fernando be
.
Upon substituting m=3 and n=5 in section formula we will get,
Therefore, the fountain is located at point (-1,-0.5).
Answer:
No, not a probability distribution.
Step-by-step explanation:
It appears that one of the probabilities in the table (-.3) is negative, which is not allowed.
Yes that’s the correct answer
Hello,
Let's x then number of students.
x is divisible by 12,15,18 thus by 180 (lcm)
x=180*k is a square
2²*3²*5*k= a square ==> k=5
x=180*5=900
Proof:
900/12=75
900/15=60
900/18=50
900=30²
1 and 2 are the only factors of 2
