Answer:
(a)0.3303
(b)0.6697
Step-by-step explanation:
Point estimation is the use of sample data to calculate a single value which serves as a best estimate of a given unknown population parameter.
Total Sample=1226
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
Answer:
C
Step-by-step explanation:
Using the pythagorean theorem, we can determine if these are right triangles or not.
equation: sqrt a^2+b^2=c
this means the square root of the two shortest sides squared must equal to the largest side, (the hypotenuese).
Work for C:
Squareroot of 32^2 + 24^2 = 40cm
Answer:
0=x
Step-by-step explanation:
9-(6x+1)=3x+8
9-6x-1=3x+8
9-8-1=3x+6x
9-9=9x
0=9x
0÷9=x
0=x
