Answer:
36cm(squared)
Step-by-step explanation:
The top rectangle is 8*(6-4)2=16cm
the bottom is the square which is 4*5=20cm
16+20=36cm(squared)
9 x 2 = 18
6 x 3 = 18
and 18 x 1 = 18
Answer: 0.24 +/- 0.088 = (0.152, 0.328)
Step-by-step explanation:
The point estimate p is given by;
p= 24/ 100 = 0.24
Z value for 96% confidence interval is 2.05
The solution for the given confidence interval is derived using the equation
p +/- z√(pq/n)
Where p = 0.24 q= 1-p = 0.76, n=100 z= 2.05
= 0.24 +/- 2.05√(0.24×0.76/100)
= 0.24 +/- 2.05(0.0427)
=0.24 +/- 0.088
= ( 0.152, 0.328)
