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)

The safe load, L, of a wooden beam of width w, height h, and length l, supported at both ends, varies directly as the product of
gladu [14]

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

Two samples, each with n=5 scores, have a pooled variance of 40. What is the estimated standard error for the sample mean differ
quester [9]

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
