Answer:
volume = 537.2 cm^3
Step-by-step explanation:
base area = (pi / 4) * d^2
= (pi / 4) * 6^2 = 28.3 cm^2
volume = 28.3 * 19 = 537.2 cm^3
Answer:
The 80% confidence interval is
Step-by-step explanation:
From the question we are told that
The sample size is n = 23
The sample mean is ![\= x = 0.036 \ cc/m^3](https://tex.z-dn.net/?f=%5C%3D%20x%20%3D%200.036%20%5C%20cc%2Fm%5E3)
The standard deviation is ![\sigma = 0.012](https://tex.z-dn.net/?f=%5Csigma%20%20%3D%200.012)
From the question we are told the confidence level is 80% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of
is
Generally the margin of error is mathematically represented as
=>
Generally 80% confidence interval is mathematically represented as
=>
4:3
3:1
6:2
hope this is what you need and hope it helps :)
10) S is the midpoint of RT.
Sx= Rx+Tx/2=2
Tx=13
Sy=Ry+Ty/2= -1
Ty= -1
T=(13,-1)
11) Sx=Rx+Tx/2=-4
Rx= -1
Sy=Ry+Ty/2= -6
Ry= -9
R=(-1,-9)
12)B is midpoint of AC.
Bx= Ax+Cx/2=-5
By= Ay+Cx/2= 1
B=(-5,1)
E is midpoint of BD.
Ex= Bx+Dx/2=-4
Dx=-3
Ey=By+Dy/2=-3
Dy=-7
D=(-3,-7)
The y intercept is -4 and the 2/3x is the slope
