Answer:
0.0208<p<0.0592
Step-by-step explanation:
-Given the sample size is 400 and the desired proportion is 16.
-The confidence interval can be determined as follows:
#We the use this proportion to find the CI at 95%:
![CI=0.04\pm 1.96\times \sqrt{\frac{0.04(1-0.04)}{400}}\\\\=0.04\pm 0.0192\\\\=[0.0208,0.0592]](https://tex.z-dn.net/?f=CI%3D0.04%5Cpm%201.96%5Ctimes%20%5Csqrt%7B%5Cfrac%7B0.04%281-0.04%29%7D%7B400%7D%7D%5C%5C%5C%5C%3D0.04%5Cpm%200.0192%5C%5C%5C%5C%3D%5B0.0208%2C0.0592%5D)
Hence, the 95% confidence interval is 0.0208<p<0.0592
Answer:
1) B
2) C
3) B
Step-by-step explanation:
Radius = D/2 = 7/2 × 2 = 7/4
Circumference = pi × D
= 7/2 pi
7/2 × 3.14 = 10.99
Approximately 11
Answer:

Step-by-step explanation:
Answer:
Step-by-step explanation:
Notice when x increases 1, y is 4 times the previous one, so
the function is like 
To determine the constant C, put any pair of (x, y)
Use x = 0, y = 0.2, so
0.2 = 
= C * 1 = C
then
1) 24 square cm
2) 35 square cm
3) 9 square cm
4) 40 square cm
5) 18 square cm
6) 40 square cm
to find the area of a rectangle, all you have to do is multiply the length by the width.
