To get the Area you need the Radius to get the Radius you need to divide 14 by 2 14/2=7
The Radius is 7 now to get the area we need to multiply 7 by 7 but also add pi 3.14
7*7*3.14=153.86
Average rate = distance / time
distance = average rate x time
Range of distance = 2.2(1) to 2.2(3) = 2.2 to 6.6
Required range is all real numbers from 2.2 to 6.6, inclusive.
Answer:
C
Step-by-step explanation:
Reflect over y axis the rotate 180 degrees.
X=

Or it would be approximately: x≈ 0.37228132, -5.37228132
Hope this helped! ;P
Answer:
It would change to 0.04802
Step-by-step explanation:
from this question we have that n became 400
40% of 400
= 160
p* = 160/400
= 0.4
1 - p* =
= 1 - 0.4
= 0.6
at confidence level,
1 - 0.95
= 0.05
alpha/2 = 0.025
z= 1.96
<u>margin of error. E</u>
= 1.96 x √[(0.4 x 0.6)/400]
= 1.96 x 0.0245
= 0.04802
M.E = 0.04802
