Number who said that they were not confident that the food they eat in country A is safe=405.
The point estimate of those who said that they were not confident that the food they eat in country A is safe is given as 
(a)Point Estimate for p,

(b)Point estimate for q,
1- (point estimate for p)
=1-0.3303
=0.6697
Hypotenuse therom ( a^2 + b^2 = c^2)
1) find c^2
22^2 + 16.1^2= c^2 ———->743.21
2) square root c^2 to find c
square root of 743.21 = 27.2 so D
Answer:448
Step-by-step explanation:
So to start,you can see that 8 times 2 is 16.And 16 times 4 is 64.So the pattern is times 2 then times 4 then times 6.On the edges you can see 64.You multiply 64 by 6 and you get 384.Then you multiply 8 times 6 that equals 48.And you multiply 4 times 4 and get 16.After you add 384 and 48 which equals 432.And then your done.(I think that's the answer)
If the box is a square and the length of one side is 46cm, then the area of the box in square centimeters is 46 * 46 = 2116.
