The latest poll of 400 randomly selected residents showed that 288 of them are hoping that the old town cinema stays open on Mai
Varvara68 [4.7K]
The approximate margin of error is 4%.

Using the formula given and our information, we have:

E=1.96\times \sqrt{\frac{\frac{288}{400}(1-\frac{288}{400})}{400}}&#10;\\&#10;\\=1.96\times \sqrt{\frac{0.72(1-0.72)}{400}}=1.96\times \sqrt{\frac{0.72(0.28)}{400}}&#10;\\&#10;\\=0.044\approx 0.04=4%

Stevan wants to build a fence around a square garden that is 506.25 ft squared. How many feet of fence will he need to complete
drek231 [11]

For side length s, the area of a square is given by

... A = s²

Then the side length can be found to be

... s = √A = √(506.25 ft²) = 22.5 ft

The perimeter is the sum of the lengths of the four equal sides.

... P = 4s = 4·(22.5 ft) = 90 ft

Stevan will need 90 ft of fence to complete the job.

A triangle has side lengths of 9 in, 13 in, and 20 in. What is the measurement of this triangle’s largest angle? 29.9° 129.9° 13
Kryger [21]

Answer:

x =  129.9 degrees to the nearest tenth.

Step-by-step explanation:

The largest angle will be opposite the longest side (20 in). So by the Cosine Rule:

20^2 = 9^2 + 13^2 - 2*9*13 cos x      where x is the  largest angle.

cos x =  (20^2-0.640 - 9^2 - 13^2) / (-2*9*13)

cos x = -0.641025641

x =  129.87 degrees.
