Answer:
Win=436584.2477 cm3/min
Step-by-step explanation:
Volume for a conical tank
V=π/3 r^2 h
We need a relation between r and h
r/h=252.5/1301.3=0.194 --> r=0.194h
sust. in Volume equation
V=π/3 (0.194r)^2 h=0.0394h^3
taking derivative with time respect in both sides
dV/dt=3(0.0394) h^2 dh/dt and we know when h=404cm, dh/dt=22.022 cm/min
dV/dt=3(0.0394)(404)^2 (22.022)=424984.2477 cm^3/min
Also, we know
dV/dt=Win-Wout and Wout=Win-11600.01160
Finally
Win=424984.2477+11600.0116
Answer
Win=436584.2477 cm3/min
Answer:
Hello some data related to your question is missing attached below is the missing data
a) we will reject the null hypothesis hence it can be determined that the salary of politicians is greater than that of EMTs through the use of two-sample t procedures. since ( to > critical value )
b) <em>( 3.819 , 8.5226 ) </em>
Step-by-step explanation:
Applying the Given data:
The test hypothesis :
H0 : μ1 = μ2
Ha : μ1 > 2
A) since ( to > critical value ) we will reject the null hypothesis hence it can be determined that the salary of politicians is greater than that of EMTs through the use of two-sample t procedures
B ) construct and interpret
next calculate the SP value
=
where: S1 = 7524 , n1 = 50 , n2 = 100 , S2 = 5551 ( input values into equation above )
∴ = 39354491.3716
hence : = 6273.32
next calculate the value of test statistic
to = ( X1 - X2 - Δo ) / Sp
where: X1 = 61234 , X2 = 54529 , Sp = 6273.32 , n1 = 50 , n2 = 100 ( input values into equation above )
to = 6705 / 1086.5702 = 6.1708
Df ( degree of freedom ) = n1 + n2 - 2 = 148
critical value at ∝ = 0.01 = ± 2.3518 ( using excel function : T.INV(0.01,148) )
hence the confidence Interval
= ( 6.1708 ± 2.3518 )
<em>= ( 3.819 , 8.5226 ) </em>
