Answer:
The correct answer is "4.8137 m³". The further explanation is given below.
Explanation:
Firstly we have to calculate the concentration of Se:
Concentration the fish can take:
According to the general dilution principle will be:
⇒
The volume that can take the farmer will be:
On converting this into m³, we get
=
Finally the volume the farmer can remove would be:
Answer:
Explanation:
Sample size, n=20
Degrees of freedom is 1
Number of degrees of freedom for error is n-2 hence 20-2=18
Total number of degrees of freedom is 18+1=19
Standard error estimate is
Here,
Coefficient of determination
Here,
The total sum of squares is
SS total=SSR+SSE=7200+1800=9000
MSR=SSR=7200
F value is given by
The ANOVA table is then
Answer:
attached below is the detailed solution and answers
Explanation:
Attached below is the detailed solution
C(iii) : versus the parameter C
The parameter C is centered in a nonlinear equation, therefore the standard locus will not apply hence when you use a polynomial solver the roots gotten would be plotted against C
Answer:
The outer diameter of the ball is 6.2138 cm
Explanation:
The formula to apply is ;
Heat loss ,
where ;
Q/t=total heat loss from the ball = 1600 w
k=coefficient of heat transmission through the ball= 2.75 W/m.˚C
A=area in m² of the ball with the coefficient of heat transmission
T₁=Hot temperature
T₂=Cold temperatures
d=thickness of the ball
Area of spherical ball using internal diameter, 3cm= 0.03 m will be
Radius = half the diameter = 0.03/2 = 0.015
Area = 4 *π*r²
Area = 4*π*0.015² = 0.002827 m²
Apply the formula for heat loss to get the thickness as:
1600 = {2.75 * 0.002827 *(250-30 ) }/d
1600 =1.711/d
1600d = 1.711
d=1.711/1600 = 0.001069 m
d= 0.1069
Using internal radius and the thickness to get outer radius as;
3 + 0.1069 = 3.1069 cm
Outer diameter will be twice the outer radius
2*3.1069 = 6.2138 cm
