Answer:
0.5220
Step-by-step explanation:
Since the probability of contamination is 0.15, the probability of no contamination is 1 - 0.15 = 0.85
The probability that they are all contaminated will be 0.85 * 0.85 0.85 * 0.85 = 0.52200625
This is 0.5220 to four decimal
There are 10,254 toy trucks
and 10,254 * 3 = 30,762 toy cars.
In total, there are 10,254+30,762= 41,016 toys
when we divide 41,016 by 35, the quotient is the number of the full boxes, and the remainder is the number of toys left.
41,016=35*1171+31
Answer: 1171 full boxes, 31 toys left for the last box
Answer:

Step-by-step explanation:
Given
The attached graph
Required

This is the point where

On the attached graph;
when 
Hence:

Note that
108° = 90° + 18°
so
sin(108°) = sin(90° + 18°) = sin(90°) cos(18°) + cos(90°) sin(18°) = cos(18°)
Then
sin²(108°) + sin²(18°) = cos²(18°) + sin²(18°) = 1
by the Pythagorean identity.
