Find the total surface area of this cuboid.

-Dominant- [34]

Step-by-step explanation:

I just learned this in class lol

Find the area of all the sides.

This cubiod has 6 sides.

6 x 5 = 30

4 x 5 = 20

6 x 4 = 24

30 + 30 + 20 + 20 + 24 + 24 = 148

Thefore, the surface area of this cuboid is 148.

Hope this helps! If it did, please mark it as brainliest! It would help a lot! Thanks! :D

Answer:

The minimum sample size required to construct a 95% confidence interval for the population mean is 65.

Step-by-step explanation:

We are given the following in the question:

Population standard deviation,

$\sigma = 3.10\text{ milligrams}$

We need to construct a 95% confidence interval such that the estimate is within 0.75 milligrams of the population mean.

Thus, the margin of error must me 0.75

Formula for margin of error:

$z_{critical}\times \dfrac{\sigma}{\sqrt{n}}$

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

Putting values, we get,

$0.75 = 1.86\times \dfrac{3.10}{\sqrt{n}}\\\\\sqrt{n} = \dfrac{1.96\times 3.10}{0.75}\\\\\sqrt{n} = 8.101\\\Rightarrow n = 65.63\approx 65$

Thus, the minimum sample size required to construct a 95% confidence interval for the population mean is 65.
