Mathematics

Given - Length of the Rectangular Plot : 16 meters

Given - Width of the Rectangular Plot : 4 meters

We know that - Area of a Rectangle is given by : Length × Width

:\implies  Area of the Rectangular plot = (16 × 4) m²

:\implies  Area of the Rectangular plot = 64 m²

Given : Square plot and Rectangular plot have same Area

:\implies  Area of Rectangular plot = Area of Square plot

:\implies  Area of Square plot = 64 m²

We know that - Area of Square is given by : Side × Side

:\implies  Side × Side = 64 m²

:\implies  S² = 64 m²

:\implies  S² = 8² m²

:\implies  S = 8 m

<u>Answer</u> : One side of the Square Garden plot is 8 meter

Answer:

Side of the square plot = 8 m

Step-by-step explanation:

l = 16 m

b = 4 m

Area of the rectangular plot = l * b

                                                 = 16 * 4 = 64 m²

Area of square plot = Area of rectangular plot

          side  *  side    = 64 m²

                    side       =  √64 = 8 m

A researcher is 95% confident that the interval from 5.2 hours to 7.8 hours captures u = the true mean amount of time
igor_vitrenko [27]
<h3>Answer: Choice B</h3>

No, this is not a plausible value for the population mean, because 5 is not within the 95% confidence interval.

====================================================

Explanation:

The greek letter mu is the population mean. It has the symbol \mu which looks like the letter 'u' but with a tail at the front or left side.

The question is asking if mu = 5 is plausible if the researcher found the 95% confidence interval to be 5.2 < mu < 7.8

We see that 5 is <u>not</u> in that interval. It's a bit to the left of 5.2

Since mu = 5 is not in the interval, it's not a plausible value for the population mean.

Have we ruled it out with 100% confidence? No. Such a thing is not possible. There's always room for (slight) error. The researcher would need to do a census to be fully confident; however, such practices are very time consuming and expensive. This is the main reason why statistics is important to try to estimate the population with a sample.

Tina is saving to buy a notebook computer. She has two options. The first option is to put $200 away initially and save $10 ever
omeli [17]

The <em>correct answers</em> are:


It would take 5 months and she would save $250.


Explanation:


Let m be the number of months.


For the first way of saving, $200 up front and $10 each month, the expression would be

200+10m.


For the second way of saving, $100 up front and $30 each month, the expression would be

100+30m.


Setting them equal gives us the equation

200+10m = 100+30m


Subtract 10m from each side:

200+10m-10m = 100+30m-10m

200 = 100+20m


Subtract 100 from each side:

200-100 = 100+20m-100

100 = 20m


Divide both sides by 20:

100/20 = 20m/20

5 = m


It would take 5 months.


$200 up front and $10 each month for 5 months:

200+10m

200+10(5)

200+50

250


She would save $250.
