Answer:
y=11
Step-by-step explanation:
your slope when you use y2-y1
---------
x2-x1
will become -12/0 so the equation will be y=11
The size of the next smaller scale wil about 1.464.
The scale factor represents the change between the different sizes. We multiply by it to increase and divide by it to reduce.
1.772 / 1.21 = 1.464
A = -11
B= -12
This is because of how calculations work in negatives. Because they are both negative they work similarly to addition
Answer:
95% confidence interval for the proportion of preschool children vaccinated in that suburb lie between (.5042 , .6958) 0r 50.42% to 69.58%
Step-by-step explanation:
Given -
A random sample of 100 preschool children in Camperdown revealed that only 60 had been vaccinated
Sample size ( n) = 100
Sample proportion = = 0.6
confidence interval = 95%
1 -.95 = .05
= = 1.96
95% confidence interval for the proportion of preschool children vaccinated in that suburb =
=
=
=
= (0.6 - .0958) , (0.6 + .0958)
= (.5042 , .6958)
