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)
First it is reflected in the x axis (beacuse the x value becomes negative but the y values stays the same)
second its dilated by a factor of a half ( the sides of the figure are reduced by a half)
then its translated 2 units to the left and 2 units upwards
V = lwh
V = 35 x 15 x 22
V = 11,550 m³
hope this helps :)
Answer:
O A. Yes, because 92 + 122 = 152
B. No, because 9 + 12 15.
C. Yes, because 92 + 122> 152.
