Answer:
A = - 2n - 1
Step-by-step explanation:
A=-3+(n-1)(-2)
<=> A = - 3 - 2(n-1)
<=> A = - 3 - 2n -2×(-1)
<=> A = - 3 - 2n + 2
<=> A = - 1 - 2n = - 2n - 1
Answer:
Step-by-step explanation:
The irregular shape's area consists of the sum of the areas of all the shapes that make it up.
Area of pink triangle:
Area of purple square:
Area of green quadrilateral:
Area of blue triangle:
Therefore, the area of the irregular polygon is .
The perimeter of the irregular polygon consists of certain shred sides from the four polygons that make up:
Answer: Garou has 0 apples left.

Step-by-step explanation:
a. P(mites OR ticks) = P(mites) + P(ticks) − P(mites AND ticks)
P(mites OR ticks) = 0.80 + 0.30 − 0.20
P(mites OR ticks) = 0.90
b. P(no ticks | mites) = P(no ticks AND mites) / P(mites)
P(no ticks | mites) = (0.80 − 0.20) / 0.80
P(no ticks | mites) = 0.75
c. If two events are independent, then P(A and B) = P(A) × P(B).
P(mites AND ticks) = 0.20
P(mites) × P(ticks) = 0.80 × 0.30 = 0.24
They are not independent.
