Answer:

32,000 square feet gross area and 28,750 square feet net area

Step-by-step explanation:

Given a rectangular site measures 125 feet (frontage) by 256 feet (depth), of which 26 feet is in the public right of way. We have to find the the gross and net site area.

As, 26 feet width is in the public right of way which excluded in the net area but included in gross area.

For gross area,

Length=125 feet

Width=256 feet

$Area=Length\times width=125\times 256=32000 square feet$

For net area,

Length=125 feet

Width=256-26=230 feet

$Area=Length\times width=125\times 230=28750 square feet$

Hence, last option is correct.

The answer is: 32,000 square feet gross area and 28,750 square feet net area

Researchers found a linear relationship between tail-feather length (in mm) and weight (in g) in a random sample of 20 male long

Dafna11 [192]

Answer:

Step-by-step explanation:

As far as I know, this question is not correct. I have the searched the internet and found a similar question which makes sense. In the correct question, 95% Confidence Interval is already given calculated from the software and

<em>95% prediction interval is asked (PI) for the weight of one male long tailed finch weighing 20 g.</em>

We have this data given in the correct question found on internet. And they have calculated this data using software:

New Obs = 20

Fit = 92.34

SE Fit = 5.26

95% Confidence Interval = (81.29, 103.38)

95% Prediction Interval = (67.61, 117.06)

Now, Just look at the prediction interval:

Now the formula for Prediction Interval = Point Estimate ± Margin of Error

Upper limit for prediction interval = 117.06

lower limit = 67.61

Formula for point estimate = (Upper + Lower)/2

Point Estimate = (117.06 + 67.61)/2

Point Estimate = 92.34

Formula for margin of error = (Upper - Lower)/2

Margin of Error = (117.06 - 67.61)/2

Margin of Error = 24.72

Formula for Prediction Interval = Point Estimate ± Margin of Error

PI = 92.34 ± 24.72

I'm not sure what your variables are, but I will try task 3 with you.

y=$500(in billions)

x= the number of years that have passed since 2009

percentage of decrease: 1 - % =

so your formula will look like this: y(1 - %)^x

Write a division equation that can be solved by multiplying each side by <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B9%7D%7B

sveta [45]

For example:
(4/9) x=8

Now can solve this equation multiplying each side by 9/4.

(9/4)(4/9)x=(9/4)8
x=18

To check:
(4/9)(18)=(4*18)/9=72/9=8
