Hello,
y=sin²(cos(2x))
y'=2*sin(cos(2x))*cos(cos(2x))*(-sin(2x)*2)
= -4*sin(cos(2x))*cos(cos(2x))*sin(2x)
Answer:
each person will pay $10.36 for tickets and snacks.
Answer:
2257 pounds
Step-by-step explanation:
First, get the volume of each and since density is the same, we shall use the density to get the other mass
First volume
Volume=lwh where l is length, w is width and h is height.
Substituting with the given figures
Volume=4*9*168=6048
Density
Density is mass per unit volume
D=m/v
Mass is given as 7900 pounds
Density is 7900/6048=1.3062169312169
Volume of second box
V=2*6*144=1728
Mass is product of volume and density hence 1.3062169312169*1728=2257.1428571428 pounds
Rounded off as 2257 pounds
Estimated standard error for the sample mean difference= 17.93
<u>Step-by-step explanation:</u>
<u> </u>Given data,
n=5
variance, σ =40
Standard error = σ / sqrt (n)
= 40/ sqrt (5)
= 40/2.23
=17.93
Estimated standard error for the sample mean difference= 17.93
