Answer:

346.88 meters

Step-by-step explanation:

Given that the area of the square-shaped terrain is 470 square meters.

Let a be the side of the terrain, so

Area of the square-shaped terrain, a^2=470 square meters.

Therefore, the length of one side, a=\sqrt {470}=21.68 meters.

The length of single thread wire required in circulating the square-shaped terrain = the perimeter of the square-shaped terrain

As the perimeter of a square having side a = 4a

So, the length of single thread wire required in circulating the square-shaped terrain= 4 x 21.68 =86.72 meters

Therefore, the length of 4 thread wire required in circulating the square-shaped terrain= 4 x 86.72=346.88 meters.

X) = 5x^3 -2x and g(x) =3x^3. Find f(x) + g(x) &amp; state the domain!
expeople1 [14]
To add two functions, combine like terms. (5+3x^(3)) = 8x^3-2x. The domain is all real numbers. There is no bound on how small or large the numbers can be for cubed functions.

A process produces batches of a chemical whose impurity concentrations follow a normal distribution with a variance of175. A ran
Tom [10]

Answer:

the probability that the sample variance exceeds 3.10 is 0.02020 ( 2,02%)

Step-by-step explanation:

since the variance  S² of the batch follows a normal distribution , then for a sample n of  20 distributions , then the random variable Z:

Z= S²*(n-1)/σ²

follows a χ² ( chi-squared) distribution with (n-1) degrees of freedom

since

S² > 3.10 , σ²= 1.75 , n= 20

thus

Z > 33.65

then from χ² distribution tables:

P(Z > 33.65) = 0.02020

therefore the probability that the sample variance exceeds 3.10 is 0.02020 ( 2,02%)

Sue Jones is insured for bodily injury in the amount of 10/20. She is at fault in an accident in which Albert Smith is injured.
lianna [129]
For this case, what you should know is that Sue Jones insurance covers half of the expenses. Equivalently, her insurance covers:
 10/20 = 1/2 = 0.5
 Therefore, we have then that
 a. for Albert 
 0.5 * (12000) = $ 6000
 b. for Sam 
 0.5 * (8000) = $ 4000
 c. total
 The sum of the results of parts a and b
 $ 6000 + $ 4000 = $ 10,000
 answer
 $ 6000
 $ 4000
 $ 10,000
