Answer:
0.6 or 60%.
Step-by-step explanation:
Given: There are 8 number of boys in the class.
There are 12 number of girls in the class.
Now, finding total number of students in the class of Mr Rossi.
Total number of students=
∴ Total number of students in the class=
Next finding the probability of having representative will be a girl.
Probability of having girl=
⇒ Probability of having girl=
∴ Probability of having girl as a representative=
Converting the fraction into decimal, we will get 0.60 and in percentage, we will get 60%.
∴ 0.60 or 60% probability that the representative will be a girl.
Answer:
D (2,-2)
Step-by-step explanation:
- The coordinates are the pair (x,y) in the axis.
- We already have three vertexs: a: (x,y)=(2,3); b:(x,y)= (7,3) and c: (x,y)=(7,-2).
- If you see the picture attached, where all points available are in pink, you will see that the distance between the sides that are already defined equals 5.
- Because all squares have equals sides, then we must find the missing side that will be at a distance of 5 between the other two vertexs.
- That point is d (x,y)=(2,-2).
