The width is 3 feet. If you set up your equation like so...
lwh = A
(4) (2) (w) = 24
Then proceed to divide 24 by 4 and 2.
(4) (2) (w) = 24
/4 /4
2w = 6
/2 /2
w = 3 feet
B = x^2−x / 3g

Answer:A - smoothing constant
Step-by-step explanation: A smoothing constant is forecasting model, a parameter that provides the weight given to the most recent time series value in the calculation of the forecast value.
This smoothing constant determines how the historical time series values are weighted and it must have a value between 0 and 1.
There are three smoothing constants and they are: alpha, betta and gamma.
It will take 6 days for it to reach 9F hope this helps
From the information given, we have that:
1. The null hypothesis is: ![H_0: \mu = 85](https://tex.z-dn.net/?f=H_0%3A%20%5Cmu%20%3D%2085)
2. The t-statistic is t = 3.78.
Item 1:
We want to test if there is a significant difference from the population mean of 85, thus, at the null hypothesis, it is <u>tested if the population mean is of 85</u>, that is:
![H_0: \mu = 85](https://tex.z-dn.net/?f=H_0%3A%20%5Cmu%20%3D%2085)
Item 2:
The t-statistic is given by:
![t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%7D%7D)
In which:
- X is the sample mean.
is the value tested at the null hypothesis.- s is the sample standard deviation.
- n is the sample size.
For this problem, we have that:
. Then:
![t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%7D%7D)
![t = \frac{90 - 85}{\frac{7}{\sqrt{28}}}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B90%20-%2085%7D%7B%5Cfrac%7B7%7D%7B%5Csqrt%7B28%7D%7D%7D)
![t = 3.78](https://tex.z-dn.net/?f=t%20%3D%203.78)
The t-statistic is t = 3.78.
