Answer:

C. 0.12

Step-by-step explanation:

<u>Independent events</u>

The outcome of one event does not affect the outcome of the other. If A and B are independent events then the probability of both ocurring is:

P(A and B) = P(A) x P(B)

With P(A) = 0.40 and P(B) = 0.30 then

P(A and B) = 0.40 x 0.30 = 0.12

Find this shape’s area
natali 33 [55]

Answer:

90ft

Step-by-step explanation:

I draw it out and add a dotted line to make a triangle and rectangle then you find the area of them individually and add the two together.

Rectangle:

6*3=18

Triangle:

Add the 6+6 together to get the height of the triangle and subtract the 3 from the 15 to get the base

(12*12)\frac{1}{2}

144/\frac{1}{2}

72

Total area:

18+72

90ft

The central angle of a regular polygon is 18 degrees. Th e perimeter of the polygon is 144 ft. What is the area of the polygon t
Diano4ka-milaya [45]
Given that the central angle of a polygon is 18, then the number of sides of the polygon will be:
360/18
=20 sides
thus the side length will be:
144/20
=7.2 ft
hence the area will b given by:
p=s×n
a=s/[2tan(180)/n]
where:
Area=(a×p)/2
p=perimeter, s=side length, n=number of sides
p=7.2×20=144
a=7.2/[2tan (180/20)]=22.73
thus
A=(144×22.73)/2
A=1632.524 ft²
