An oil tank has to be drained for maintenance. The tank is shaped like a cylinder that is 3.5 ft long with a diameter of 1.8 ft.

Suppose oil is drained at a rate of
1.7 n' per minute. If the tank starts completely full, how many minutes will it take to empty the tank?
Use the value 3.14 for at, and round your answer to the nearest minute. Do not round any intermediate computations.

Answer:

5 minutes

Step-by-step explanation:

Volume of cylinder = πr²h

Radius, r = diameter / 2 = 1.8 /2 = 0.9

Volume of cylinder = 3.14 * 0.9² * 3.5

Volume = 8.9019 feet³

Drain rate = 1.7 ft per minute

Volume / drain rate

8.9019 / 1.7

= 5.2364117

= 5 minutes (nearest minute)

Answer:

We select the option c.

y=0.114x+0.691

Step-by-step explanation:

<u>Best Fit Regression Model</u>

Scientists often wonder if there is a relationship between the variables under study. It's a vital matter in modern times where artificial intelligence technology is struggling to find answers where traditional approaches hadn't before.

The most-used tool to find relations between variables is the regression model and its best fit lines to try to find an expression who relates variable x (years from 1960) and variable y (minimum wage requirement) as of our case.

The data was entered into a digital spreadsheet and an automatic function was applied to find the best-fit model.

The automated tool's output was this equation:

y=0.11363x+0.6906

That can be rounded to three decimals

y=0.114x+0.691

We select the option c.
