Huh what the heck is this i’m confused
Answer:
Event A. P(A) = 1/28
Event B. P(B) = 1/56
Step-by-step explanation:
Event A. We have 3! ways of arranging the juggler, acrobat and pianist and ⁶P₁ ways of arranging the rest of the performers. We ave ⁹P₁ ways of arranging all the performers.
So, P(A) = 3!⁶P₁/⁹P₁ = 3!6!/9! = 3!6!/(9 × 8 × 7 × 6!) = 6/(3 × 8 × 7) = 1/28
Event B. We have ³C₁ ways of combining the violinist, acrobat and comedian in any order and ⁶P₁ ways of arranging the rest of the performers. We ave ⁹P₁ ways of arranging all the performers.
So, P(B) = ³C₁ × ⁶P₁/⁹P₁ = 3!6!/9! = 3 × 6!/(9 × 8 × 7 × 6!) = 3/(3 × 8 × 7) = 1/56
That depends on the shape of the triangle.
A scalene triangle has no lines of symmetry.
An isosceles triangle has one line of symmetry.
An equilateral triangle has three lines of symmetry.
If my hunch is correct, Watson, there is no triangle
with two and only two lines of symmetry.
Answer:They intercept each other on one point
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Since x has a negative coefficient, the graph opens downwards meaning that it has a maximum.
The vertex formula is y = a(x - h)^2 + k so the coordinate must be (-6, 6).
