Answer:
139
Step-by-step explanation:
Inside angles of a triangle = 180 degrees
61 + 78 = 139
180 - 139 = 41
unknown interior angle = 41 degrees
So m<1 = 139
(Or just add the two interior angles together)
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:
2
Step-by-step explanation:
It is the number before the variable (m).
