Answer:
The coordinates of the reflected triangle are ,
and
.
Step-by-step explanation:
Let be a point , reflections across x- and y-axes are represented by the following operations:
x-Axis reflection:
y-Axis reflection:
If we know that ,
and
, the coordinates after both reflections are, respectively:
The coordinates of the reflected triangle are ,
and
.
Answer:
(a)
(b)
i.
ii.
iii.
Step-by-step explanation:
Given
Solving (a): List all possible elements using set-roster notation.
The possible elements are:
And the number of elements are:
Solving (bi) Exactly 1 girl
From the list of possible elements, we have:
And the number of the list is;
The probability is calculated as;
Solving (bi) At least 2 are girls
From the list of possible elements, we have:
And the number of the list is;
The probability is calculated as;
Solving (biii) No girl
From the list of possible elements, we have:
And the number of the list is;
The probability is calculated as;
so the slope of that line above is really -4/3, now
