23.21 is the answer i believe
Answer:
1.0
Step-by-step explanation:
The 6 is bigger than 5, so that bups the number up to 1.0.
Answer:
1329.85≤μ≤1330.14
Step-by-step explanation:
z score for 99% confidence interval
from the z table we can find that the score for 99% confidence is 2.58
formula
z=![\frac{x-μ}{[tex]\frac{{σ}[tex]\sqrt{n}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-%CE%BC%7D%7B%5Btex%5D%5Cfrac%7B%7B%CF%83%7D%5Btex%5D%5Csqrt%7Bn%7D)
}[/tex]}[/tex]
where
x-sample mean
μ-population mean
σ-population standard deviation
n-sample size
2.58=![\frac{1330-μ}{[tex]\frac{{442}[tex]\sqrt{24}](https://tex.z-dn.net/?f=%5Cfrac%7B1330-%CE%BC%7D%7B%5Btex%5D%5Cfrac%7B%7B442%7D%5Btex%5D%5Csqrt%7B24%7D)
}[/tex]}[/tex]
1330-2.58×24÷442≤μ≤1330+2.58×24÷442
1329.85≤μ≤1330.14
Answer:
14 x (2 + 5)
Step-by-step explanation:
This is because 2 and 5 do not have a factor greater than 1
Answer:Volume = Area of the base × height
Step-by-step explanation:
If the rectangular box were filled with 1 cm cubes, there would be:
6 × 2 cubes in the bottom layer
As there are 3 layers,
Volume = 36 cubic centimetres
Now note that the area of the box's base is given by:
Area = 12 square centimetres
From the above discussion, we can derive a formula for the volume of a rectangular box as follows:
