The answer is 1600m2 assuming the side of the barn is at least 40 meters long.
An enclosure is usually a parallelogram and since you already have one side you need to make three more. If you dive 120m by 3 you get 40m. Each wall will be 40m. The enclosure ends up being a square and a formula for a square is base times height, therefore the dimensions of the enclore would be 40m times 40m which gives you the answer of 1600m2.

How do you write 3.5 × 10^3 in standard form?
Nutka1998 [239]

Answer:

3500

Step-by-step explanation:

Given the following question:

3.5\times10^3

To convert a scientific notation into standard form we first need to keep in mind that the exponent in indeed a positive. Knowing this we know that the decimal point is going to move to the right.

Since the exponent is three, we know that the decimal point is going to move to the right THREE times.

3.5\times10^3
3.5\times10^3=3.5.0.0.
3.5.0.0.=3500
=3500

Your answer in standard form is "3500."

Hope this helps.

Answer:

- 6.547

Step-by-step explanation:

Given that:

Sample size (n) = 1207

p = 0.85

p0 = 0.92

The test statistic :

Z = (p - p0) / √(p0(1 - p0) / n)

Z = (0.85 - 0.92) / √(0.92(1 - 0.85) / 1207)

Z = - 0.07 / √(0.92(0.15) / 1207)

Z = - 0.07 / √0.0001143

Z = - 0.07 / 0.0106926

Z = - 6.5465446

Z = - 6.547
